This car drives like a regular plug-in hybrid as it silently cruises along on just its electric motors. However, mash the gas pedal and the twin-turbo V8 comes to life with a snarl, rocketing you to extra-legal speeds in the blink of an eye. It's as stealthy as it is sleek, reaching speeds up to 93 mph on electric power alone when E-Drive mode is engaged.
