Chevrolet quietly announced a new hypercar with 1,250 horsepower. It is the stunning cross between the ZR1 and a hybrid power train.

The ZR1’s turbos are the largest ever installed on a production passenger car, according to GM. The inertia of such large turbos is a recipe for turbo lag—that’s the delay between the time when a driver floors the gas pedal and the engine’s turbo reaches full boost to provide maximum power.
