General Motors was recently caught benchmarking the Porsche Taycan, the German automaker’s all-electric four-door sedan, which was spotted in the vicinity of GM’s Milford Proving Ground.
Offered as Porsche’s first all-electric production vehicle, the Porsche Taycan is available in multiple body styles and configurations, including the Taycan Sedan, the Taycan Sport Turismo, and the Taycan Cross Turismo. The Sedan model lineup incorporates a gently sloping roofline and four-door body, while the Sport Turismo and Cross Turismo incorporate a longer roofline and more hatch-like rear end.
Looking over the images, it appears as though GM is benchmarking the base-model Porsche Taycan Sedan. Specs for the base model include 242 miles of driving range on a full charge (EPA estimate, Performance Battery Plus), 321 horsepower (up to 402 horsepower with Overboost Power mode and Launch Control active), and 254 pound-feet of torque. The sprint to 60 mph takes 5.1 seconds, with top speed set at 143 mph. Pricing for the base model starts at $86,700.
The rest of the Porsche Taycan Sedan lineup includes the Taycan 4S, Taycan GTS, Taycan Turbo, and Taycan Turbo S, offering increasing levels of horsepower and higher performance levels. The most expensive model is the Porsche Taycan Turbo S Cross Turismo, which starts at $190,000 and lays out 750 horsepower, enough to send the EV to 60 mph in 2.7 seconds. The Taycan Turbo S is slightly quicker to 60 mph, completing the test in 2.6 seconds, with pricing starting at $187,400.
As GM Authority exclusively covered in August, GM is considering the development of a new EV Corvette sedan to rival the Porsche Taycan and Tesla Model S. With GM poised to transition it’s entire light-duty vehicle lineup to all-electric powertrains by 2035, the prospect of a battery-powered Chevy Corvette is all but assured at this point. What’s more, GM President Mark Reuss previously confirmed that GM would offer a “fully electric, Ultium-based Corvette in the future.” With all that in mind, perhaps this benchmark is setting the groundwork for development.
