When McLaren showed its P1 concept last year, it looked like an evolution of its MP4-12C model, yet the P1 breaks cover at the 2013 Geneva auto show with a hybrid drivetrain, capable of running the car at 217 mph.

GENEVA--McLaren did the unexpected with its new P1 model: built it with a plug-in hybrid drivetrain. In that respect, it follows the Porsche 918 Spyder as a high-performance hybrid. The P1 uses a carbon fiber monocoque body, rear-wheel drive, and a midmounted engine. The lightweight construction, perfect for a high-performance car, also helps its electric drive system.
Top speed: 217 mph (electronically limited) 0 to 62 mph: under 3 seconds 0 to 187 mph: under 17 seconds

The engine in the P1 is similar to that of McLaren's MP4-12C model, a twin turbo 3.8-liter V-8. Its high compression gives it output of 727 horsepower. A 176 horsepower electric motor is integrated with the engine, the output of both being delivered to the rear wheels through a seven-speed dual clutch transmission. McLaren has not specified exactly how the power of engine and motor are combined, but the system lets the car drive under pure electric power.

Given the plug-in hybrid drive system, the P1 should be using LED headlights, but these look like standard halogen projectors. The headlight shape resembles the McLaren logo.

The sheen of ceramic brakes is obvious from the rotors. McLaren made these rotors from a new type of carbon ceramic, designed to shed heat better than current carbon ceramic braking systems. The P1 also uses braking regeneration to recharge its lithium ion battery pack.

McLaren integrated the 212 pound battery pack into the chassis. The car's charger, necessary to connect it to an electric vehicle charging station, can be stored in the luggage area or left out, to save weight. McLaren says the P1 will travel 12 miles under electric power at 30 mph, useful for urban zero emission driving.

McLaren calls the automated wing a Drag Reduction System (DRS). In track driving, the wing can provide maximum downforce. On public roads and when using electric power, the wing will lessen downforce for better range.

These racing bucket seats use a traditional shoulder seat belt harness.

Buttons on the steering wheel activate the Drag Reduction System and the Instant Power Assist System, the latter letting loose the full potential of the electric drive system to complement the engine's output. Carbon fiber shift paddles on the steering column allow for manual sequential gear selection. The center stack also holds a small LCD for controlling and viewing the car's infotainment features. The instrument cluster is also LCD-based.

Instead of a shifter, the McLaren P1 uses buttons for the various drive modes.
If you have not put your order in for the P1 by now, it is probably too late. McLaren only plans on building 375. Of course, at a cost of about $1.3 million each, not many will be able to afford one.
