GENEVA — The McLaren P1's hybrid powertrain will produce 903 horsepower and 663 pound-feet of torque, the automaker confirmed on Wednesday ahead of the supercar's debut at the 2013 Geneva Auto Show.

The supercar is a plug-in hybrid, and is equipped with a plug-in charger that can recharge the battery in only two hours.

The critical bits of information about the production-ready McLaren P1 continue to round out the preview of the supercar ahead of its unveiling. Pricing, however, has not yet been announced.

The McLaren P1 is equipped with a mid-mounted twin-turbo V8 engine, an upgraded version of the M838T unit fitted to the McLaren MP4-12C. The P1's electric motor is mounted directly onto the engine. All drive is channeled through the dual-clutch seven-speed gearbox to drive the rear wheels. The car also features a lightweight battery pack that weighs 212 pounds and is mounted onto the underbody of the carbon-fiber chassis.

The V8 is rated at 727 hp, while the electric motor produces 176 hp.

McLaren did not provide fuel economy estimates on the P1. The McLaren P1 can travel in electric mode for up to six miles. The lightweight electric motor is unique to the McLaren P1. The company did not say how fast the P1 is under electric-power only, but noted "even in E-model the performance is strong."

The hybrid setup "ensures versatility and ease of transportation, allows use in low-emission zones and residential driving is optimized with near-silent running," the company said in a statement.

Two steering-wheel-mounted buttons activate the Drag Reduction System and the Instant Power Assist System, two Formula 1-derived technologies.

With the Drag Reduction System, speed is increased by reducing the amount of drag on the rear wing. The system immediately deactivates when the button is released or if the driver touches the brake pedal.

The driver will be able to activate the electric motor via the Instant Power Assist System. "The instant response of the electric motor provides a sharper throttle response more associated with a normally aspirated engine," said McLaren.

Edmunds says: Details on the McLaren P1 plug-in hybrid continue to fall into place. Pricing is expected at the supercar's debut in Geneva.
