- McLaren M838T engine
-
The McLaren M838T engine is a 3.8 litre twin-turbocharged flat-plane V8. Developed with help from Ricardo with technology acquired from Menard Competition Technologies, it is McLaren's first engine.[1] The engine redlines at 8500 rpm, however 80% of the engines torque is available as low as 2000 rpm.[2][3] The design of the engine was based on the Nissan VRH35 racing engine used in Le Mans in 1998. However, other than the 93 mm bore, little of that engine remains in the M838T.[4] McLaren claims that the engine has the highest horsepower to CO2 emission ratio of any current production engine.[5] The engine is built at Ricardo's engine assembly facility in Shoreham-by-Sea, West Sussex.[6]
Applications
The engine was designed and built for the McLaren MP4-12C supercar where it produces 592 horsepower and 466 ft·lbf of torque. For the GT3 racecar, the engine produces less power at only 493 hp.[7]
