GM Authority has once again spotted The General benchmarking the Ford Mustang Mach-E electric crossover near the GM Milford Proving Ground, showing that testing of the popular EV model from GM’s cross-town rival is still ongoing.
Spy photographers from GM Authority obtained shots of the Mustang Mach-E EV in its white exterior paint as it continued road testing in late August 2023, including the image shown below.
We previously spotted and photographed the exact same vehicle out on the road for benchmarking back in December 2021. Some 20 months later, GM has either been constantly testing the Ford Mustang Mach-E throughout the intervening time, or more likely has retrieved it from storage to study some aspect of its performance in a new series of benchmarking tests.
This particular unit of the Ford Mustang Mach-E is outfitted with the instruments and transmitters needed to collect the performance data The General wants to obtain while putting it through its paces. It is also marked as a benchmarking vehicle by the small white sticker attached to the driver-side corner of the rear bumper.
As we previously detailed, this specific Mustang Mach-E is a Premium trim vehicle, while the “X” on the front-door Mach-E nameplate badge indicates the extended-range battery is equipped. The powertrain consists of an 88 kWh battery with 150 kW DC quick charge capacity. Motivation is supplied by a single-motor RWD setup developing 290 horsepower and 317 pound-feet of torque. Per-charge driving range is 303 miles for the 2022 model-year vehicle, and 310 miles for the 2023 model.
GM is following standard practice in the auto industry by benchmarking competitor’s vehicles, though as with the first appearance of this Mustang Mach-E back amid the snows of a Michigan winter almost two years ago, its appearance on public roads where it can be photographed is rather unusual.
Back in late 2021, almost simultaneous with GM testing the Mustang Mach-E, Rivian was also photographed benchmarking the Blue Oval’s Mustang-branded crossover, as was reported on our sister site Ford Authority. Rivian and Ford originally had a partnership with the goal of developing EVs jointly, but this fell through and each automaker pursued its own electric vehicle program.
The Ford Mustang Mach-E not only outsells its ICE counterpart, but also outsold the Chevy Bolt EUV by roughly a hundred units in Q2 2023. However, the Chevy Bolt family, including the Chevy Bolt EV alongside the EUV, sold several thousand more units during the second quarter, continuing a trend already seen in Q4 2022.
