The MP4-12C features a carbon fibre composite chassis, and is powered by a mid-mounted McLaren M838T 3.8-litre V8, twin-turbo engine developing approximately 616 bhp (459 kW; 625 PS) and around 443 lb·ft (601 N·m) of torque. The car makes use of Formula 1-sourced technologies such as "brake steer",where the inside rear wheel is braked during fast cornering to reduce understeer. Power is transmitted to the wheels through a seven-speed Seamless Shift dual-clutch gearbox.

I love that Mclaren opts to go for a highly tuned V8 instead of just throwing in bigger and bigger engines. Solid engineering!
