HIGH POINT, N.C. – Thomas Built Buses (TBB), a leading manufacturer of school buses in North America and a division of Daimler Truck Specialty Vehicles, today announced the launch of Saf-T-Liner eHDX2 Wattson, the company’s first electric Type D school bus. Type D, or “transit-style” buses, are the largest in the industry, featuring a flat front, high seating capacity and unparalleled visibility for drivers managing busy routes. Built on Thomas Built’s proven HDX2 platform and designed for districts ready to take the next step in electrification, Wattson draws from years of EV manufacturing experience and customer input to deliver a solution engineered for long-term fleet planning.

“Wattson represents our next step in electrification,” said T.J. Reed, president and CEO of Daimler Truck Specialty Vehicles. “It reflects our belief that the best electric solutions are the ones that feel familiar, fit within your fleet and are built to last. That’s what we’ve heard from our customers, and that’s what we’re delivering.”

Wattson is powered by Accelera’s 14Xe electric axle, the same system featured in Jouley Gen 2. The integrated e-axle combines the motor, gearbox and power electronics into a single, compact unit. This results in smoother driving performance and fewer mechanical parts, which means less maintenance and fewer service disruptions.

Wattson performance highlights include:

Battery capacity: 246 kWh
Estimated range: Up to 150 miles
Charging: Standard SAE CCS1 charging; 2–3 hours at a DC fast-charging station (minimum 60 kW output); V2G-capable system; optional AC/DC SAE J1772 CCS1 charging with 20kW onboard charger for additional flexibility while on the road
Charging range: 20kW (AC); 120kW (DC)
Torque and power: 295 peak horsepower; 750 lb-ft of torque
Two-speed transmission
Liquid-cooled battery system
Additional features:

277” wheelbase
LCD instrument cluster providing real-time vehicle and diagnostic data
Optional 69” pass-through luggage compartments for activity or dual-use buses
Standard rear charging port, with optional front charging available
“Wattson showcases the strength of Daimler Truck Specialty Vehicles, bringing together proven manufacturing, operational excellence and deep customer insights to deliver the right solutions at the right time,” said Jeff Allen, senior vice president of operations and specialty vehicles at DTNA. “From design through production, our teams at Thomas Built Buses and across the DTNA network are aligned to support customer needs in whatever powertrain they choose with confidence.”

“We know electrification can feel like a big step,” continued Reed. “With Wattson, we’re making that step easier by giving districts a familiar Type D solution they already trust – now in electric.”

Wattson will be available for order by the end of 2025, with initial deliveries scheduled for late 2026.

Across the country, school districts are rethinking what it means to move students safely, efficiently and responsibly. For some, that includes exploring or expanding electric bus fleets. For others, it means keeping an eye on how technology and infrastructure evolve before making the switch.

When it comes to powertrain innovation, Thomas Built Buses meets both realities — designing solutions for those ready to make a switch today and learning alongside those who have already gone through the process.

From Insight to Innovation

When Thomas Built introduced the Saf-T-Liner^® eC2 Jouley^®, it marked a milestone — the company’s first Type C electric school bus became an early signal of its commitment to cleaner, smarter student transportation. But Jouley wasn’t just an innovation; it was a learning experience.

Years of real-world operation, supported by feedback from school districts, drivers, dealers and service teams, gave Thomas Built invaluable insight into what electrification looks like in practice — how buses perform in different environments, how charging infrastructure evolves and how drivers adapt to new technology.

That continuous feedback inspired the Saf-T-Liner^® eC2 Jouley^® Gen 2, released earlier this year — a reimagined version built on those lessons, delivering greater efficiency, serviceability and driving dynamics. And it was that same cycle of collaboration and learning that paved the way for Thomas Built’s next step forward: the Saf-T-Liner^® eHDX2 Wattson, the company’s first Type D electric school bus.

“Customer feedback has become one of our most valuable design tools,” says Kendra Eads, vice president of engineering at Daimler Truck Specialty Vehicles, a division of Daimler Truck North America, which includes both Thomas Built Buses and Freightliner Custom Chassis Corporation (FCCC). “Every insight from the field helps us refine performance, comfort, driver experience, reliability and serviceability. Those real-world insights translate directly into real innovation.”

No One-Size-Fits-All

Every school district approaches electrification differently. Geography, fleet size, infrastructure and route patterns all play a role in determining what works — and what doesn’t. Rather than offering a one-size-fits-all solution, Thomas Built has embraced flexibility, ensuring that both Jouley Gen 2 and the new eHDX2 Wattson are available to meet the unique needs of each customer.

With its sales and dealer teams serving as the “ears to the ground,” Thomas Built continually gathers input from the field — capturing what customers value most and where improvements can be made. That feedback moves directly into engineering and design, ensuring that every advancement — from ease of operation to serviceability — is informed by the people who rely on these buses every day.

Co-Creation in Motion

The development of Wattson became a true collaboration, fueled by the lessons learned from Thomas Built’s years of EV leadership with Jouley. Engineers worked hand in hand with districts and dealers to refine everything from torque response and drivability to serviceability and charging accessibility.

The result is a next-generation Type D electric bus that embodies Thomas Built’s learning-driven approach: pairing proven durability with cutting-edge EV technology. Features like the Accelera 14Xe e-Axle, 800-volt battery system and optional 20kW onboard charger reflect customer feedback around performance and infrastructure flexibility.

“Electrification isn’t static — it’s a journey,” adds Eads. “We’re still learning, and so are our customers. That’s what makes this work exciting. Each new model represents what we’ve learned together.”

A Balanced Path Forward

As national policies and state-level commitments shift, the future of electric school transportation remains fluid. Some districts are moving forward with confidence. Others are watching closely as funding and priorities evolve.

For Thomas Built Buses, that reality reinforces the importance of choice. The company continues to invest in advanced diesel, alternative fuels, and electric solutions alike — ensuring that every district, no matter where they are on their journey, can find the right fit for their needs.

With the introduction of Wattson, Thomas Built demonstrates that progress doesn’t mean abandoning practicality. It means offering solutions that balance innovation with reliability, vision with readiness and ambition with real-world application.

Because at the end of the day, the road ahead isn’t just about where the industry is headed — it’s about helping customers get there on their own timeline.

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.
