BMW’s latest step into its electric future comes with more stamina than we expected. The second-generation iX3 , unveiled a few months ago with a projected range of 497 miles (800 km) under the WLTP cycle, has quietly outperformed even BMW’s own estimates, though, as always, there are a few caveats tucked in the fine print.

In a real-world run, the electric SUV managed to stretch its legs to more than 621 miles (1,000 km) on a single charge.

Eager to see how far their new creation could really go, a small team from BMW decided to take the iX3 on a proper road trip. They set off from the Debrecen plant in Hungary, where the model is built, and pointed it toward Munich, the automaker’s home base in Germany.

Not only did they complete the 626.1-mile (1,007.7 km) journey, but they did so with 2 percent charge remaining, which could have been enough to travel an extra 12 miles (20 km).

What Are The Caveats?

As you could have probably guessed, the team did everything they could to extend the iX3’s driving range. For example, they avoided highways during the journey, sticking to smaller and lower-speed roads where the SUV’s regenerative braking system would be most effective.

Additionally, the iX3 was equipped with smaller 20-inch wheels, rather than the 21- and 22-inch wheels it’s also available with. They also didn’t use the heating, cooling, or radio during the test, to save as much energy as possible.

BMW picked the iX3 50 xDrive, the only version announced to date, which has a pair of electric motors delivering 463 hp and 476 lb-ft of torque, meaning it can hit 60 mph (96 km/h) in just 4.7 seconds, and a sizeable 108.7 kWh battery pack.

Crashes on Houston’s busy freeways are an unfortunate reality of city life, and one earlier this week proved especially tragic. The driver of a BMW was killed, and the driver of a Tesla Cybertruck died in hospital after the two vehicles collided in Houston, Texas.

Shockingly, police say the BMW’s driver had mistakenly entered the freeway, traveling the wrong way after driving down an exit ramp and heading westbound in the eastbound lanes.

The crash occurred around midnight on October 28 along the I-10 Katy Freeway. According to police, the BMW, whose specific model hasn’t been identified, slammed into the Cybertruck and burst into flames almost instantly. The force of the impact also pushed the Tesla into an 18-wheeler.

Initially, it was only the driver of the BMW who was declared dead on the scene, and the driver of the Cybertruck was taken to a nearby hospital in critical condition. Sadly, the Tesla driver succumbed to their injuries.

Houston Police Department Sgt. Rebecca Dallas told KHOU that the BMW driver had entered the freeway in the opposite direction, ignoring multiple Do Not Enter and Wrong Way signs along the ramp.

Investigators are expected to conduct an autopsy of the BMW driver to see if they were impaired at the time of the collision. The name of the driver who caused the crash hasn’t been released. However, the driver of the Cybertruck has been confirmed as a 38-year-old father of two young children.

Accidents Like This Are Far Too Common

Accidents like this are far from rare. More than 1100 wrong-way fatalities have been recorded across Harris County in the past decade, and last year alone, 233 people were injured in similar incidents throughout the area. Clearly, something needs to be done to reduce these numbers.

Local authorities may need to explore a combination of measures, from adding more signage to exit ramps to enhancing driver education. Small changes could go a long way toward preventing future tragedies on Houston’s highways.
