McLaren not tempted to build own F1 engine

Martin Whitmarsh has played down the likelihood that McLaren might build its own engine for the new V6 rules in 2014.

The British team's F1 chief said in March that McLaren is "ruling nothing out", after the Woking based outfit produced its own 3.8 litre twin-turbo V8 for its new MP4-12C production sports car.
