2011 Ford Mustang V-6 - new Duratec 3.7-liter
To this day, the Ford Mustang remains one of the best selling sports cars on the planet despite having an archaic suspension design and one of the worst V-6 powertrains currently in production. With the introduction of the new 2011 Ford Mustang, however, the legendary muscle car is poised to accelerate to the top of its class--both in terms of performance and fuel efficiency.
We already know that the base 2011 Ford Mustang gets a brand-new 3.7-liter V-6 engine and a six-speed manual transmission. We can now confirm that the 305 horsepower V-6 will return an EPA-rated fuel economy of 19 mpg in the city and 31 mpg on the highway--the first time a production car with more than 300 horsepower has achieved a fuel economy of more than 30 mpg. By comparison, the similarly powerful Chevrolet Camaro V-6 returns a fuel economy of 18 mpg in the city and 29 mpg on the highway, while the Dodge Challenger gets by with 18 mpg in the city and 25 mpg on the highway.
The Mustang's stellar numbers are achieved with variable control of the engine’s valve operation right across the rev range. The 3.7-liter unit’s variable cams operate on Ford's new Direct Acting Mechanical Bucket (DAMB) valvetrain using polished buckets and roller finger followers to reduce friction. The end result is as much as a three percent improvement in fuel economy and a ten percent improvement in power output versus traditional engines without these advanced features. Furthermore, a cold air induction system and dual exhaust give the advanced powerplant its free-breathing feel, 7,000 rpm redline and near-instantaneous response to throttle inputs.
Further reducing fuel consumption is the Mustang’s electronic steering system and minor aerodynamic improvements such as the new front fascia, tire spats on the rear wheels, modified underbody shields, taller air dam and an added rear decklid seal.
