Like an IndyCar, you can summon up the electric boost through the Instant Power Assist System with a steering-wheel button. The P1 will even travel for six miles on electric power alone, fueled by the dense power pack mounted at the bottom of the carbon-fiber chassis that can be charged in just two hours. Oh, and if you notice a second, blue button on the steering wheel labeled DRS, that’s the Drag Reduction System that adjusts the rear wing angle at speed. In short, it's an F1 car for the road - just what you'd expect from McLaren.
