McLaren P1 Engine Details Released - Total Output is an Impressive 903bhp

McLaren has released powertrain details for the P1 supercar, which combines a mid-mounted 3.8-litre twin-turbo V8 petrol engine and a highly effective electric motor for a total output of 903 bhp and a maximum torque figure of 900Nm.

The 3.8-litre twin-turbo V8 petrol engine in the McLaren P1 is a new version of the M838T unit, producing 727 bhp at 7,500 rpm, and 720Nm of torque from 4,000 rpm. The lightweight electric motor, developed by the McLaren Electronics produces another 176 bhp.

In purely electric model, the P1 has a range around 6 miles and when the battery is empty, the petrol engine will automatically start to maintain drive and charge the battery.

The electric motor can be activated via the Instant Power Assist System (IPAS) button mounted on the steering wheel. There is also a button for the Drag Reduction System (DRS), a technology similar to that employed on Formula 1 cars. In short the McLaren P1 has a wing that reduces in angle to lower drag by 23%.

McLaren P1 will debut in early March at the Geneva Motor Show.
