Tata has re-entered the Indian SUV segment with the comeback of the Sierra, reviving a nameplate that has been absent for more than two decades. The reborn Sierra arrives with near concept-car styling, modern technology, and a price tag that feels shockingly affordable for what it offers.

The new Sierra first appeared as a concept in 2023, and the production version remains remarkably faithful to that design. Its squared-off silhouette and rugged stance lend it Land Rover vibes, a detail made all the more interesting given Tata’s ownership of JLR.

Premium Looks

The strong B-pillar and wraparound rear glass nod to the original three-door Sierra of 1991, which stayed in production until 2003. Those retro cues meet contemporary details like glossy black cladding, aluminum-effect skid plates, sculpted rear haunches, and an upright tail capped with full-width LEDs.

Base models sit on 17-inch steel wheels, while top trims roll on 19-inch alloys with a more polished look. The overall design wouldn’t feel out of place alongside a modern-day Freelander or even a compact Defender.

Tata has also given us a glimpse of the upcoming Sierra EV that stands out thanks to a Tesla-like full-width LED bar and a grille-less look for the redesigned front bumper.

The Sierra measures 4,340 mm in length, 1,841 mm in width, and 1,715 mm in height, with a 2,730 mm wheelbase and 205 mm of ground clearance. That footprint plants it squarely among rivals such as the Hyundai Creta, Kia Seltos, Honda Elevate, Suzuki Grand Vitara / Victoris, Toyota Urban Cruiser Hyryder, Skoda Kushaq, and VW Taigun.

High-Tech Interior

Step inside and the Sierra greets you with a triple-screen setup: a 10.25-inch digital cluster, a 12.3-inch infotainment screen, and a matching 12.3-inch passenger display.

The options list runs deep, including a 12-speaker JBL system with a dashboard sound bar, ambient lighting, dual-zone climate control, wireless charging, ventilated seats, and what Tata calls the largest panoramic sunroof in its class.

Tata promises a roomy and comfortable five-seat cabin, finished with soft-touch materials and offering a 622-litre (22-cubic-foot) boot. The company has also placed strong emphasis on safety, even showcasing a crash test that recreated a vehicle-to-vehicle impact. Standard equipment includes six airbags and an ADAS suite with Level 2+ autonomous features.

Flexible Underpinnings

The Sierra rides on Tata’s new ARGOS platform (All-Terrain Ready, Omni-Energy, and Geometry Scalable architecture), designed to support multiple powertrain types.

At launch, the Sierra will be available with a naturally-aspirated 1.5-liter gasoline engine producing 105 hp (78 kW / 106 PS), a turbocharged 1.5-liter with 158 hp (118 kW / 160 PS), and a 1.5-liter turbodiesel with 116 hp (87 kW / 118 PS).

Transmission choices include a six-speed manual, a seven-speed dual-clutch, or a six-speed automatic. All versions are front-wheel drive for now, with selectable terrain modes, but all-wheel drive is planned. Later on, the lineup will expand to include fully electric, hybrid, and CNG options.

Priced To Sell

And that brings us to price, arguably the Sierra’s biggest talking point. Tata has announced a starting figure of ₹11.49 lakh (around $12,800 or about what you’d pay for a bespoke color at Range Rover), which positions it as strong value in its class.

Even so, it lands just above the Hyundai Creta, priced from ₹10.72 lakh ($12,100), which continues to dominate India’s SUV charts.

Orders for the Sierra open on December 16, with deliveries beginning January 16. For now, Tata says the model will be sold exclusively in India, with no export plans on the table.

EV adoption in India, the world’s most populous nation, has been slower than policymakers anticipated, but the country’s Supreme Court now believes it may have found a new lever to accelerate change.

The judges have urged the government to consider a gradual phase-out of luxury ICE cars, arguing that a targeted approach could push cleaner mobility without disturbing the broader market.

The bench suggests that withdrawing luxury and premium models with combustion engines, including hybrids and plug-in hybrids, could act as a test case for a measured “phased transition” toward electric mobility.

According to Autocar India, EVs already account for around 12 percent of sales in the premium segments, far higher than the 2–3 percent share seen among mass-market models.

Could a Luxury Ban Spark an EV Shift?

Critics point out that luxury vehicles represent a tiny fraction of India’s automotive landscape, arguing that the proposed ban would have a limited impact on national emissions. Others blame the weak scrappage policy for the country’s aging fleet of cars and LCVs which poses a far bigger pollution problem.

Others point instead to the weak vehicle scrappage framework, which leaves aging cars and light commercial vehicles on the road far beyond their prime, an issue that poses a much larger pollution challenge.

Even so, the court maintains that an EV-only requirement for high-end models would send a clear signal without harming affordability for the masses and disrupting the nation’s new car market.

As India Today reports, Justice Kant noted that carmakers already offer a range of premium electric models matching the comfort and performance of their combustion counterparts.

He explained, “Since these vehicles cater to a very small and affluent segment, imposing restrictions on high-end petrol and diesel cars can be a starting point. The common man will not be affected.”

The Government’s Willing To Discuss

Luxury brands such as Mercedes and BMW already maintain substantial zero-emission lineups, yet an internal combustion ban would inevitably reshape their operations in India, bringing possible ripple effects for local employment and supplier investment.

More: EU May Quietly Ban Gas Rentals Starting In 2030

For now, the idea remains a proposal without firm timelines. However, the Supreme Court has asked the government to review its National Electric Mobility Mission Plan, with another hearing scheduled for December.

India’s Attorney General confirmed that the administration is “alive to the idea,” citing ongoing coordination across 13 ministries and departments, covering everything from manufacturing incentives to charging infrastructure.

Toyota has just unveiled the new generation of the Hilux, and while the new model has barely touched showroom floors, it’s already been reimagined to showcase just how far owners can take customization.

More: New Toyota Hilux Debuts Sumo-Inspired Looks And EV Option

During the truck’s official launch in Thailand, the brand presented a lineup of rugged, modified builds, blending genuine factory accessories with a few aftermarket touches to hint at the model’s versatility.

GR Flavor in Full Effect

The display featured no fewer than six distinct takes on the pickup, each aimed at a different type of driver. One stood out for its GR Parts catalogue treatment, equipped with a black grille, red skid plate, glossy black fender extensions, branded side steps, and black wheels wrapped in chunky off-road tires.

Accessories from Toyota’s Gazoo Racing division didn’t stop there. The brand also showcased roof and bed racks, plus the signature red mudflaps familiar to GR-badged models.

A GR Sport version of the new Hilux is expected to follow, with a tougher stance, refined performance, and chassis upgrades tailored to those seeking a sharper drive.

Interestingly, the GR Parts build wasn’t the star of the show. That honor went to an off-road-focused version developed by Australian tuner ARB, which looked ready to tackle almost anything.

It sat higher thanks to a lift kit and wore a rugged front bumper with clearance cutouts, auxiliary LEDs, a roof rack, a side awning, and a bed rack designed for specialized gear.

Overlanding Camper

Still, what caught our eye was an overlanding camper conversion of the Hilux with a tent mounted on a custom bed rack. The adventure-packed model came with a lifted suspension, all/terrain tires, beadlock wheels, rock sliders, a skid plate with integrated lights, an LED bar on the roof, and an aerodynamic snorkel.

Another rugged example took a different visual route, wearing a matte gray-and-red color scheme with a snorkel, protective hardware, raised suspension, and carbon-plated tailpipe. Mudflaps and new wheels rounded out its stance.

Unlike the European and Australian Hilux, which come exclusively in double-cab form, the Thai-market truck is available in Standard Cab and Smart Cab configurations.

The Standard Cab provided the base for a particularly practical build featuring a lift kit, black wheels, white-and-black graphics, extended mirrors, and a metal cage that expanded the load capacity of the open cargo area.

Rounding out the lineup was a sportier, road-focused Hilux finished in yellow with a carbon-textured wrap for the hood and tailgate. It sat lower on new wheels, backed by uprated brakes, though the heart remained unchanged, a 2.8-liter turbodiesel producing 201 hp (150 kW / 204 PS).

Depending on the market, the new Hilux range will also include mild-hybrid diesel, petrol, and fully electric options, underscoring its global versatility.

Available Accessories

Toyota Thailand’s official website lists a comprehensive range of add-ons for the new Hilux. Among them are additional plastic cladding for the doors, larger wheel arch extensions, door handle covers, a rear spoiler, stainless steel exhaust outlets, and bed liners.

Owners can also choose underbody protection and metal-look garnish for the taillights, tailgate, hood, and bumper intakes. Inside, options include heavy-duty floor mats, aluminum scuff plates, and clever storage solutions.

Thailand has a prominent tuning culture, which is why most automakers advertise the customization capabilities of their trucks. Judging from the aforementioned builds and the popularity of the Hilux, we expect to see a lot of interesting conversions in the future.

While the Ford F-150 dominates North America, the Toyota Hilux continues to reign just about everywhere else. Now entering its ninth generation, Toyota’s workhorse returns with sharper styling, a thoroughly redesigned cabin, reinforced ladder-frame underpinnings, and, for the first time, a fully electric powertrain.

More: Toyota’s Baby Land Cruiser FJ Looks Retro Enough To Break Your Heart

The new design theme, dubbed “Cyber Sumo,” takes a different path from the hammerhead styling found in other recent Toyota models. Up front, slimmer LED headlights flank a body-colored honeycomb grille, while angular bumper intakes and a solid skid plate add a functional, squared-off presence.

The fully electric version wears a unique front bumper with a closed grille and redesigned intakes, a subtle cue to its zero-emission identity.

The profile remains familiar because the greenhouse, pillars, and doors carry over from the outgoing model that’s been around since 2015. Even so, re-sculpted front and rear fenders with boxy wheel arches, paired with fresh wheel designs, give it a tougher stance.

At the rear, the Hilux shows more definition than before, with sharper LED taillights and a modernized bumper that now incorporates practical side steps similar to those on the Ford Ranger.

Its footprint stays consistent with its predecessor at 5,320 mm in length and a 3,085 mm wheelbase. Toyota has chosen to offer only the dual-cab version in Europe and Australia, while markets such as Thailand retain the Single Cab and Smart Cab configurations.

How Has The Interior Changed?

The cabin has been thoroughly overhauled, blending modern tech with the Hilux’s traditionally utilitarian nature. A boxy dashboard frames a free-standing 12.3-inch infotainment screen (8-inch in the base Thai-spec model) and a 12.3-inch digital instrument cluster (7-inch in lower trims). Importantly, physical controls remain for core functions such as climate and audio, preserving tactile ease of use.

The chunky steering wheel with buttons is borrowed from the Land Cruiser, while the compact gear knob and drive mode selector sit on the center console. Dual storage compartments line the passenger side, and dashboard-mounted cupholders complete the layout.

Toyota has also expanded the Hilux’s safety credentials with a “significantly extended” suite of advanced driver-assistance systems, bringing it in line with the brand’s passenger car range.

Multiple Powertrain Options

Toyota’s “Multipathway” approach to propulsion continues here, and the new Hilux exemplifies it. Depending on the market, buyers can choose from the familiar 2.8-liter turbodiesel engine in regular or mild-hybrid form, as well as a 2.7-liter gasoline option.

The biggest leap, however, is the all-electric version. It uses dual electric motors producing a combined 193 hp (144 kW / 196 PS), powered by a 59.2 kWh battery pack.

Toyota quotes a range of 240 km (149 miles) under the WLTP cycle, or just over 300 km (186 miles) using NEDC standards. It may not rival long-range EVs, but Toyota plans to add a hydrogen fuel-cell variant by 2028.

Payload and towing capacities remain robust: up to 1,000 kg (2,205 lbs) and 3,500 kg (7,716 lbs) respectively for internal combustion models. The Hilux BEV, with its heavier battery setup, carries 715 kg (1,576 lbs) and tows 1,600 kg (3,527 lbs).

Upgraded Underpinnings

Under the skin, the Hilux rides on an upgraded version of the IMV ladder-frame architecture of its predecessor rather than moving to the more modern TNGA-F used by the Tacoma and Land Cruiser. 

Still, it benefits from a new electric power steering, new engine and cabin mounts for reduced vibrations, new front rail extensions for improved crash perfromance, and a revised suspension setup.

The suspension setup combines independent coil springs at the front with a rigid rear axle supported by leaf springs. Toyota Australia says there are two distinct calibrations: one tuned for heavy-load and towing performance, and another focused on everyday ride comfort.

In terms of off-road credentials, the 4×4 versions use a part-time 4WD system with high and low range ratios, now improved with the standard fitment of a rear locking differential and the available Multi-Terrain Select system.

Pricing and Availability

Production remains centered in Thailand, where the diesel-powered Hilux Travo is already on sale, priced between ฿767,000 ($23,700) and ฿1,366,000 ($42,200). The fully electric model starts at ฿1,491,000 ($46,100), placing it at the top of the lineup.

The new Hilux will reach Europe and Australia in December 2025, followed by broader Asian rollouts in 2026 and a home-market debut in Japan by mid-2026. Detailed specifications and pricing for each region will be announced closer to launch.

The California Air Resources Board (CARB) proposed an emergency action to continue enforcing engine emissions regulations because it says federal government efforts to undo them could result in the sale of vehicles that are not certified to any standard.

As California’s lawsuit continues against the Trump administration, challenging the presidential executive order in January directing federal agencies to terminate state emissions waivers and a resulting revocation of those waivers through the Congressional Review Act (CRA) signed into law in June, CARB said it wants to provide regulatory certainty and flexibility to manufacturers. For school buses and trucks, manufacturers could meet the Omnibus Low-NOx regulation adopted in 2020 or the previous regulation that met the U.S. Environmental Protection Agency levels set in 2010. The CRA this spring revoked three waivers, one of which allowed CARB to set a new level of 0.05 g/bhp-hr of NOx.

The public had five business days from Monday’s announcement to weigh in on CARB’s intent to enact its Emergency Vehicle Emissions Regulations by filing comments with the state’s Office of Administrative Law.

The emergency regulations do not address the Advanced Clean Trucks rule, which the CRA also revoked an EPA waiver for.

“The amendments would confirm that, until a court resolves the uncertainty created by the federal government’s actions, certain antecedent regulations (displaced by Advanced Clean Cars II and Omnibus) remain operative (as previously adopted) with the caveat that CARB may enforce Advanced Clean Cars II and Omnibus, to the extent permitted by law, in the event a court of law holds invalid the resolution purporting to disapprove those waivers,” the proposal reads.

In other words, manufacturers would be able to continue certifying engines under either the earlier-adopted emissions standards or the more stringent standards.

CARB noted that most engine and vehicle manufacturers have already planned on or achieved compliance with the more stringent emissions requirements. But CARB also warned that manufacturers choosing to certify to previous emissions levels assume the risk of having engines out of compliance with regulations, should current legal cases brought against the Trump administration go in California’s favor.

Cummins spokeswoman Drew Blair told School Transportation News that it was premature to respond in detail to CARB’s proposal, as it was not final. But she added Cummins is following the issue closely.

“Cummins is focused on delivering products with the power and performance our customers need to get their jobs done, while also meeting emissions requirements,” she commented. “We also will continue to advocate for national standards to bring clarity to our business and customers and ensure efficient and affordable products are available to power their needs.”

Earlier this month, a group of vehicle manufacturers led by Daimler Truck North America, the parent company to Thomas Built Buses, filed a suit against CARB, claiming the agency would need to re-enact previous legislation before it could enforce earlier emissions regulations.

“In the event the vehicle manufacturer’s claims were deemed correct … then CARB must take immediate action to maintain a stable vehicle market in the state and prevent the sale of vehicles into the state that would not be certified to either set of standards …,” CARB writes. “… Otherwise, in light of these unprecedented circumstances, there may remain questions — for the first time since CARB’s program began decades ago — as to whether any California standard is in effect.”

A Daimler Truck spokesperson said Wednesday the company could not comment on CARB’s proposal.

International, the parent to IC Bus, signed onto the Daimler Truck lawsuit. An International spokesman declined comment because the litigation is ongoing.

Meanwhile, CARB said Tuesday 23 percent of new medium- and heavy-duty vehicle sales in 2024 were zero emissions, more than double the minimum statewide requirement. The data is based on 30,026 zero-emission trucks, buses and vans reported to CARB by manufacturers. School buses are included in the reporting.

It was the fourth year in a row that ZEV sales increased. More than 57,000 ZEVs have been sold in California since 2021.

New research published by the World Resources Institute (WRI) and Carleton University finds that the U.S. could see an estimated $1.6 billion in societal benefits every year by using electric school buses.

This first-of-its-kind data released Wednesday accounts for the cost of using diesel-burning school buses as compared to using electric school buses, measured by two metrics: Health impacts and climate effects. WRI stated that by “comparing these costs at the local level, the data provides annual societal benefit figures in dollar terms for every county in the contiguous U.S.”

People in every state would experience positive benefits from ESBs, the research suggests, but it would be most pronounced in countries operating the oldest-burning school buses, and in communities with higher proportions of people of color and in countries with larger populations and dense, urban areas.

Still, the research indicates New York, California, Florida and Texas are poised to benefit the most from ESBs. However, nearly every county nationwide stands to benefit by using electric school buses, with the study finding more than $509,000 in average annual benefits per county and some counties seeing more than $30 million in societal benefits each year. Annual benefits vary by county based on school bus fleet size, population density, electricity fuel type mix, and age of the current diesel fleet.

“For years, communities in New York have experienced outsized impacts of diesel pollution,” commented Matt Berlin, CEO of New York City School Bus Umbrella Services. “As this new data from WRI proves, school bus electrification makes sense for New Yorkers. Investing in electric school buses means making the bus ride for kids and bus attendants and drivers on the bus quieter and healthier. Beyond the bus itself, reducing pollution near schools and in the communities where we all live means we all enjoy these benefits.”

WRI stated that the research is among the first to “model and quantify the county-level health and climate impacts of using electric school buses instead of aging diesel-burning school buses.”

When looking at the the factors of population health and climate change, the research notes that about 90 percent of the nearly half-million school buses operating in the U.S. run on diesel fuel and the harmful pollutants in diesel can cause respiratory illness, cognitive impairment and cancer, as recognized by the World Health Organization.

ESBs, however, produce zero tailpipe emissions and have the lowest greenhouse gas footprint of any school bus type at the national level, even when accounting for emissions from the associated electricity generation, the research claims. It examines the effects of diesel-burning school buses in operation, as well as the production and distribution of the fuel used.

The health impacts of diesel-burning school buses were estimated by determining the excess mortality associated with exposure to PM2.5, despite federal regulations over the past 15 years that have reduced diesel emissions by approximately 90 percent. The impacts were calculated into dollar figures based on a sociological metric that reportedly looks at how much society is willing to pay for small reductions to the risk of dying from health conditions that may be caused by environmental pollution. The sociological metric is referred to as the Value of a Statistical Life.

Meanwhile, the climate impacts of diesel-burning school buses were measured by calculating the Social Cost of Carbon, an established metric for the societal damage from extreme heat, sea level rise, food insecurity and other impacts of climate change, from these buses’ carbon dioxide emissions. The study notes that because health impacts were measured only by excess mortality from PM2.5, there are likely more health benefits of electric school buses that aren’t captured in this data, including reduced exposure to ozone pollutants, nitrogen dioxide, nitrogen oxide (NOx) and volatile organic compounds, or VOCs.

Further Studies Needed

 

A technical note acknowledges several research limitations in addition to only studying excess mortality of PM2.5 and recommends additional environmental analysis and higher resolution modeling in urban areas. The study does not address environmental justice or equity benefits of ESBs and disparities in air pollution based on race, ethnicity or income, the latter which the researchers said could reveal additional ESB benefits for marginalized communities. The research also makes assumptions about brake and tire-wear emissions and relies on “not yet mature” ESB operational parameters and emissions based on data from 2020 that does not account for changes in fleet composition changes, vehicle standards and the electricity grid. Additionally, benefits per ton remain consistent between 2016 and 2020 and “may not fully capture changes in atmospheric composition or emissions.”

Once the costs of diesel school bus impacts were determined, the research calculated the same types of impacts for ESBs, including electricity generation, and compared them to that of diesel to provide a dollar figure from each county.

Brian Zepka, research manager for WRI’s Electric School Bus Initiative said the research used a new modeling approach to trace air pollution back to its source, “allowing us to directly attribute which health impacts stem from diesel-burning school buses. While other approaches start with the air pollution source and estimate its impact, this approach, developed in peer-reviewed research funded by the Health Effects Institute, starts with the health impacts, like early deaths from air pollution, and traces that pollution back to its source—in this case, school buses.”
WRI noted the research “uses state-of-the-art models and county-level data to more specifically estimate where electric school buses would provide the most health and climate benefits through reduced emissions. It doesn’t look at the cost to own or operate different types of school buses, instead examining the impact on society from the use of the buses.”

Sue Gander, director of WRI’s Electric School Bus Initiative, said the new research shows “undeniably” that ESBs give kids a cleaner ride to school.

“In every region of the country, North, South, East and West, communities stand to see real, significant benefits from the cleaner air and reduced emissions of electric school buses. And as this research demonstrates, everybody wins when kids get to school on a clean ride, to the tune of $1.6 billion dollars every year in health and climate benefits nationwide,” she said. “Given the outsize benefits of electrifying the most polluting diesel-burning school bus fleets, and the concentration of those buses in low income areas and areas with more people of color, this data reinforces the need to ensure that those most impacted by diesel exhaust pollution are among the first to benefit from electric school buses.”

The 10 percent of diesel-burning school buses that are the most polluting are responsible for nearly 50 percent of the total health impacts of diesel-burning school buses nationwide, the research notes. Breaking that down by per-mile health impacts from diesel school buses, while varying, results to under $10 to nearly $4,000 per 1,000 miles driven, depending on the school bus age and operating location.

While the research only focused on PM2.5-related premature mortality as the primary health end point, diesel-burning school buses also emit large amounts of NOx, which contribute to ozone formation and nitrogen dioxide (NO2) exposure—both are linked to asthma, morbidity and additional premature deaths.

The research does not include the additional health effects or impacts of other diesel pollutants. WRI stated the research is likely underestimating the total benefits of electrification. Incorporating NOx-related outcomes in the future could show greater contrasts between diesel and electric.

Engine manufacturers using selective catalytic reduction (SCR) emission control technology have new federal guidance allowing them to more gradually “derate” systems when diesel exhaust fluid (DEF) depletes.

U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced during the Iowa State Fair last week the new action designed to protect American farmers, truckers and other diesel equipment operators from sudden speed and power losses caused by DEF systems.

“We have heard loud and clear from small businesses across the U.S. that the current DEF system is unacceptable,” Zeldin said in a statement. “It is unacceptable that farmers, truckers, construction workers, and many other small businesses continually experience failures of diesel-powered equipment when they need it most—costing millions of dollars in lost productivity. Today, we are responding to those concerns by calling on manufacturers to take action to update their software and eliminate the unnecessary sudden loss of power and frustrating shutdowns that too many Americans have experienced.”

EPA issued the guidance urging diesel engine and off-road farm equipment manufacturers to revise DEF system software in existing vehicles and equipment to prevent these sudden shutdowns. Starting with model year 2027, all new diesel on-road trucks and motorcoaches must be engineered to avoid sudden and severe power loss after running out of DEF.

EPA said it also has a fix for derate issues in legacy diesel vehicles with SCR.

“To fix the problem for vehicles already in use, EPA’s new guidance, developed in collaboration with manufacturers, will work to ensure that the necessary software changes can be made on the existing fleet,” the press release notes. “In addition to providing certainty to manufacturers about how EPA wants this issue resolved, the agency is not requiring separate approvals beyond that provided in EPA’s guidance. This ensures that bureaucratic steps do not delay manufacturers’ ability to put solutions into the field.”

Since 2010, SCR has used on-board diagnostics sensors to detect when DEF runs out or diesel particulate filters clog and then initiate a rapid derate of the engine. Within four hours of DEF depletion, vehicles automatically slow to five miles per hour.

But the results for industries have been “catastrophic,” said EPA, as disruptions have occurred to logistics, agriculture and construction. Several diesel engine manufacturers also initiated recalls over their SCR technology. Cummins recalled 2010 to 2015 medium- and heavy-duty engines, including the ISB 6.7 for school buses, because the SCR unit catalysts degraded faster than expected.

“At Cummins, we recognize our responsibility in powering some of the country’s most economically vital applications, from the buses that take our kids to and from school to the trucks that deliver critical goods,” a statement from the company reads. “Collaboration with our customers is at the heart of what we do, ensuring we deliver solutions that meet their business needs while continuously innovating to improve fuel efficiency, reduce costs and enhance reliability. SCR is a widely accepted, proven technology utilized in many applications, and we are committed to working closely with the EPA and the select customers affected by SCR inducements. Together, we aim to provide regulatory certainty, greater flexibility and the dependable solutions that contribute to the American economy.”

Daimler Truck North America told School Transportation News it welcomes the new guidance.

“We are supportive of the efforts to provide more flexibility with regard to DEF inducement and are actively working on solutions to support our customers,” the statement reads.

The Engine Technology Forum and several other organizations also support the new derate guidance.

“EPA has heard from users of diesel trucks, tractors and equipment and, working with manufacturers, has responded with these adjustments to improve operational performance while ensuring emissions integrity,” Executive Director Allen Schaeffer said. “EPA’s announcement [Aug. 12] provides new guidance that allows manufacturers to adjust these systems to ensure that farmers, motor coach operators, and truckers, who all rely on diesel engines and equipment, will be able to complete critical work with sufficient lead time for scheduling maintenance and repairs.”

The Environmental Protection Agency on Tuesday announced sweeping changes to rules governing diesel exhaust fluid (DEF) systems, aimed at preventing sudden power losses that have long frustrated farmers, truckers and bus operators.

The Trump administration says the guidance, which takes effect immediately, will ease operational disruptions and reduce safety risks while maintaining emissions standards.

EPA Administrator Lee Zeldin unveiled the changes during a press call from the Iowa State Fair alongside Small Business Administrator Kelly Loeffler, Agriculture Secretary Brooke Rollins and Sen. Joni Ernst, R-Iowa.

“The United Motorcoach Association applauds the new guidance from the Environmental Protection Agency (EPA) under the leadership of Administrator Lee Zeldin regarding Diesel Exhaust Fluid regulations for motorcoaches,” remarked UMA’s President and CEO Scott Michael. “EPA’s new guidance will improve safety, avoid passengers stranded on the side of the road, and unnecessary towing costs while maintaining the goal of safeguarding the environment.”

The policy allows manufacturers to reprogram existing vehicles to avoid abrupt “derates” — a rapid reduction in engine power — that can cut a vehicle’s speed to as little as 5 mph within hours of a DEF system fault.

“This is yet another common-sense policy,” Zeldin said. “We can protect the environment and grow the economy at the same time.”

Under current rules, a sensor failure in a DEF system can trigger severe speed limits within four hours, sometimes leaving vehicles stranded mid-operation. Zeldin said the new guidance will extend that timeline significantly.

‘Massive Deregulation’

Loeffler said the new policy will save America’s 1.8 million family farms an estimated $727 million annually.

“This is massive deregulation,” she said. “It’s solving a huge, long-standing issue that has gone on for 15 years.”

Rollins called the announcement “a big deal” for producers already struggling with higher costs and frequent downtime.

“We’re doing God’s work,” she said. “This is how we return power to the people and get the strangulation of overregulation out of everyday mom-and-pop small business owners’ lives, especially our farmers.”

While much of the call centered on agriculture and freight, Zeldin emphasized the rule’s importance for the passenger transportation industry.

“This was one of the concerns we heard from bus operators,” Zeldin told Bus & Motorcoach News. “It’s a safety concern when a bus is forced to park unexpectedly on the side of the road for an extended period of time. That’s all a product of poor government policy that didn’t think through the consequences.”

Phil Streif, of Vandalia Bus Lines in Caseyville, Illinois, told Bus & Motorcoach News in a separate interview that the change is the result of years of advocacy to bring operators’ perspectives to federal regulators. Streif began contacting the EPA five years ago, warning that the four-hour repair window was “just not realistic” for the motorcoach industry.

“After countless meetings with EPA and CARB, we finally got relief,” Streif said, “but the question remained about existing fleets.”

That question led to additional negotiations — and resistance from some engine manufacturers — before regulators agreed to modify the rules for vehicles already in service.

Uncertainty over future federal regulations already has disrupted one engine maker’s plans. Cummins Inc., a manufacturer of diesel engines, announced this month the postponement of the launch of its new X15 diesel engine for heavy-duty trucks to late 2026.

Initially unveiled in February with features meeting 2027 EPA and CARB standards, the engine was set for pre-orders in mid-2025 and deliveries in 2026. A statement from Cummins touted the technology used in the X15.

“Selective Catalytic Reduction (SCR) is a widely accepted, proven technology utilized in many applications, and we are committed to working closely with the EPA and the select customers affected by SCR inducements. Together, we aim to provide regulatory certainty, greater flexibility, and the dependable solutions that contribute to the American economy.”

Ending a Safety Risk

Streif said two moments proved decisive in resolving the derating issue: meeting EPA’s Amy Kopin, “who strongly advocated for us,” and the change in agency leadership when Zeldin took over. “They came out early, promising a goal to reduce regulation and the red tape that makes our businesses more challenging to operate. After many exchanges, we made great progress, and now we’re finally at the finish line.”

The new rules give bus operators 40 hours before even a minor torque reduction — something Streif calls “a game changer.”

“There are so many things that run through your head when you see an inducement code and know you have four hours before the bus is essentially inoperable,” he said. “We’re moving the most precious cargo there is — people — and derating created a profound safety risk for our drivers and passengers.”

Streif recounted an incident just two weeks ago in which a bus in New Orleans began showing a DEF-related fault code. Mechanics attempted repairs, but the problem reappeared within hours, forcing the company to dispatch a replacement bus from Alabama to ensure passengers could return home on time.

“Something that could have waited until we got the bus back created an obstacle for us that we had limited options for,” he said.

The industry’s challenge was compounded by the scarcity of repair shops for motorcoaches, especially in remote areas or during off-hours. “There were no signs that could predict when a sensor would go bad, so it was like rolling the dice every time a bus went out,” Streif said.

Streif credited the American Bus Association, United Motorcoach Association, and International Motorcoach Group with helping build the case for reform.

“With their help and many members’ feedback, we were able to collect hard data and surveys that provided factual statistics on the impact derates have,” he said. “Honestly, without the strength of these great organizations, we probably wouldn’t have the results we were able to achieve.”

Putting Focus on Bus Industry

The advocacy also exposed a gap in federal oversight. “When I initially reached out to the EPA, their response was, ‘Oh, we didn’t even consider buses,’” Streif said. “It’s been stated before that our industry has been left out in the past, but I think that’s going to change going forward.”

He said the industry will need to maintain its presence in regulatory discussions. “Although our industry is small, we all work together in a way that other industries don’t see. That’s what will make us successful as long as we continue to support one another.”

Ernst praised the EPA’s move, calling the previous guidelines “arbitrary” and harmful to productivity. She also tied the changes to broader Republican efforts to roll back regulations enacted during the Biden administration.

Zeldin said the change reflects a broader philosophy of governance.

“Today’s guidance bridges the gap between now and 2027, ensuring existing vehicles on the road and in the field are just as dependable,” he said. “We’re both protecting human health and the environment and the people who depend on diesel engines to do their job.”

The EPA said no additional agency approval will be required for manufacturers to implement the new software changes.

For Streif, the new timeline — 40 hours before a small torque derate, then 200 hours before a 50 mph limit — is one the industry can live with. “On flat stretches we won’t see any impact,” he said. “I think we can all live with that.”

While the immediate future remains uncertain on federal emissions regulations and funding, school bus OEMs say they are prepared with varied solutions going forward to meet the needs of every customer, no matter the fuel or where they operate.

That was the key takeaway from a July 13 panel at STN EXPO West in Reno, Nevada. The OEM representatives on stage were Francisco Lagunas, general manager of North America Bus for Cummins; Jim Crowcroft, general sales manager for Thomas Built Buses; Katie Stok, product marketing and commercial readiness for IC Bus; Frank Girardot, the PR, marketing and government relations leader at RIDE; and Brad Beauchamp, EV product segment leader for Blue Bird. The session attempted to provide some clarity to the ever-changing funding and fuel landscape.

“The only certainty is that everything is so uncertain,” Lagunas punctuated during the “The Engines & Emissions Pathway Forward” session, facilitated by School Transportation News Editor-in-Chief Ryan Gray.

Lagunas added that Cummins is seeing an increased demand in diesel, confirming that the new B6.7 octane engine will be available in January. Though, he noted that investments in electric batteries and drive systems have not slowed down. Accelera, the zero-emissions division of Cummins, is a member of a joint venture with Daimler Truck North America and Paccar to create a U.S.-based battery cell manufacturer, Amplify Cell Technologies.

Crowcroft agreed, adding that one year has made a huge difference in industry focus. Several of the same panelists sat on a similar panel last year at STN EXPO, where he said EV was the focus of the industry.

“Now, it’s been a complete 180 [degree turn] this year,” he shared, adding that the industry has spent too much time talking about EVs and not enough time talking about the other offerings.

This year has been about being diverse, being nimble and ready to adapt to change when necessary. “What is the most practical plan?” he asked, noting that diesel technology has advanced and EV fatigue is setting in.

He shared that Thomas is not telling customers what fuel or energy type to use but instead empowering them to choose what works best for their fleets. Noting the Trump administration’s relaxation of a federal push for zero-emission vehicles, Crowcroft said there has been a sigh of relief from customers for not feeling like they have to purchase electric school buses.

He noted that with all the changes and technologies, it puts more pressure on the OEMs to keep up. He said Thomas is committed to investing in quality, citing that ahead of the 2027 GHG Phase 3 regulations targeting lower NOx (the EPA currently has it on hold pending a proposal to remove GHG regulations), school districts might want to pre-buy within the next 12 months to avoid cost increases tied to the new technology.

Beauchamp said Blue Bird has always focused on a fuel-agnostic path for its customers, and the company plans on continuing with propane being a low emission source. While he said Blue Bird had yet to see EV order cancellations as of last month, he anticipates those orders will flatten. Regardless, Blue Bird is committed to EV, noting an $80 million grant from the U.S. Department of Energy last year (and double that amount in company matching funds) to build a new Type D electric school bus plant.

He noted that while the supply chain has improved coming out of COVID-19, “We’re not out of the words on it, yet,” he said.

Stok noted that the industry conversation should not be about low costs but having a supplier that delivers good quality on time. She noted that, like the other OEMs, EV is still very much part of the IC Bus product portfolio, as is diesel. However, she said the change in federal regulations will usher in changing order preferences across the industry, noting that IC is reintroducing its own gasoline school bus with the upcoming Cummins engine.

For the remainder of 2025, she said IC Bus is on track to have the highest production output from its Tulsa, Oklahoma plant. Communication is key right now, she added, and the manufacturer is working with its dealer network to listen to the customers and continue to improve.

Meanwhile, Girardot said it’s too early to predict what the future holds but BYD electric school bus company RIDE believes it holds a promise to furthering the deployment of EVs and enhancing the capabilities of vehicle to grid technology. He noted that V2G holds value and is something that communities need to consider. He highlighted success stories of V2G, such as in the Oakland Unified School District in California.

Girardot added that technician training on electric school buses is a must.

Additionally, RIDE announced a range extension on its blade battery, which took home the Best Green Technology, as judged by attendees at the STN EXPO West Trade Show Innovation Awards. Girardot added RIDE, too, received a competitive grant to expand its manufacturing facility.
