NEW 2011 Ford Mustang V-6

Today, fuel economy plays an equally important part. Chevrolet fired an opening salvo by installing a potent yet thrifty V-6 into its 2010 Camaro, but Ford's firing back with its tweaked 2011 Mustang.
Ford's entry-level Mustang no longer makes do with the antiquated 4.0-liter V-6 used since the 2005 model. Instead, it gleans a new variant of Ford's Duratec V-6, which also appears in the likes of the Fusion, Edge, and Taurus. For the Mustang, it's been bored out to displace 3.7 liters, but retains its aluminum construction and twin-independent variable cam timing with the 3.5-liter unit used in the Fusion Sport.
