2010 Ford Mustang to be powered by a twin-turbo V6 engine

The biggest news is a EcoBoost V6 engine that will meet the 35mpg CAFE regulation. The EcoBoost engine, which is currently scheduled to debut in a performance version of the Fusion, could be the more fuel efficient alternative for Mustang in the long term. Depending on spec, the EcoBoost is capable of up to at least 415hp, and has the torque to match a regular V8.

If the EcoBoost version will not go into production, the V8 engine will still be very much part of the Mustang program. There won’t be much of a price difference, if any - although the base V-6 is a cheaper engine, by the time things like turbochargers are added it’s basically V-8 money, say our sources.

The current 4.6 liter V8 engine will be replaced by a 5.0 liter that will deliver around 350 hp and will be offered in a limited edition run-out series of current model Mustang GTs.
