Porsche Taycan Turbo S Spotted Testing at GMKGP Photography

Spy photographers caught General Motors testing a Porsche Taycan Turbo S at its Milford Proving Grounds in Michigan.

Seeing Porsche's most capable EV wearing Michigan manufacturer plates and lapping GM's test track adds fuel to the rumor that GM could be spinning off the Corvette nameplate as its own brand, with an all-electric sedan and SUV.

The rumor, first published by our colleagues at Car and Driver in November, suggests the two Corvette-branded EVs could launch by 2025 using an 800-volt architecture, a two-speed transmission, brake-by-wire, four-wheel steering, and torque vectoring. None of this has been confirmed by GM, of course.

As far as EVs go, the Taycan Turbo S is among the quickest in production right now. It holds the lap record for electric cars at the Nürburgring, and can rocket to 60 mph in just 2.6 seconds thanks to its 750-hp drivetrain.

This isn't the first time we've seen GM benchmarking exotics from Europe. In August 2022 spy photographers caught the company testing a Ferrari SF90 Stradale hybrid at the same Milford test track. Five months later, GM launched the Corvette E-Ray, a mid-engine V-8 hybrid of its own. Only time will tell what this testing will result in this time around.
