The P1's hybrid system is geared toward performance, not just fuel economy. The electric motors can give instant boost while the engine's turbochargers are still spinning up to speed.
With that extra boost, the car will be able to bolt from zero to 62 miles per hour in under three seconds, McLaren promises. Speeds of 124 miles per hour will be attainable in just four seconds more. The car will have a top speed that will be electronically limited to 218 miles per hour.
When driven at slow speeds -- averaging 30 miles per hour -- the car should have an all-electric driving range of about 12.4 miles, according to McLaren.
