McLaren Automotive has finally released full engine specs on its new supercar, the P1.

In total, the successor to the McLaren F1 supercar makes 903 hp and 664 lb-ft of torque thanks to a twin-turbo 3.8-liter V8 engine mated to an electric motor. The gasoline engine itself is a modified version of that found in the MP4-12C, making 727 hp and 531 lb-ft of torque, while an electric motor developed in-house by McLaren Electronics is mounted directly to the engine. It is capable of adding 176 hp and 192 lb-ft of torque. Combined in a special IPAS (Instant Power Assist System) mode, McLaren claims the turbocharged hybrid engine delivers power, “more akin to a naturally aspirated engine.”
