Acceleration from 0 to 60 mph takes less than 4.0 seconds, and to 100 mph in 12 seconds, aided by braking performance from 60 mph to 0 in less than 100 feet. Weighing less than 3400 pounds, it has a Cd of 0.39, as the aerodynamic work focuses on downforce and high-speed stability. Featuring a "double bubble" room to increase headroom, and an expanded luggage area at the back, the production model may have a bigger ducktail spoiler.
