The 3.8-litre twin turbo V8 petrol engine has upheld the honour for McLaren Automotive, having won under the '3.0-litre to 4.0-litre' category at the 2014 Engine of the Year awards. The success marks the second consecutive year McLaren has claimed the prestigious title, having been named the first new winner of the accolade for five years in 2013.

The M838T engine, designed and developed by McLaren in collaboration with Ricardo, has recently undergone significant changes to produce a class leading 641bhp and 678Nm of torque in the McLaren 650S Coupe and Spider. Acceleration from a standstill to century mark is accomplished in just 3.0 seconds, while the car returns 8.5km/L while emitting just 275g/km.

The International Engine of the Year awards were presented at Engine Expo 2014, and voted for by an independent panel of leading automotive journalists from around the world. Richard Farquhar, Head of Powertrain, and Graham Langham, Engine Manager from McLaren Automotive, received the award at a ceremony in Stuttgart, Germany.

Commenting on the engine, Co-Chairman of the Awards and one of the international judges, Dean Slavnich, explained, "Supercar trailblazing in every sense - lightweight, twin turbocharging, reduced displacement and so very flexible with a wide power output - the M838T V8 is just a wonderful piece of powertrain engineering".
