After years of complaints about the ancient old 4.0-liter V6 engine in the base Mustang, Ford has finally replaced it for 2011 and it will be paying dividends at the pump for owners. The EPA has finished certification of the fuel efficiency for the new 3.7-liter Mustang and it is both the most economical Mustang ever and the first car with over 300 horsepower to top 30 miles per gallon. When paired up with a six-speed automatic transmission, the 3.7-liter Mustang is rated at 19 mpg around town and 31 mpg on the open road. Models with the new six-speed manual transmission retain the 19 mpg city rating but drop slightly to an even 30 mpg on the highway. Those numbers top the 18/29 mpg of the V6-powered 2010 Chevrolet Camaro.
The new engine, along with careful calibration of the new transmission, was the most important part of the mileage equation. However, replacing hydraulic power steering with electric power assist and numerous small aerodynamic tweaks helped, too. 2011 Mustangs are available for order now and deliveries will start in the next few weeks. We're told that this is just the beginning of the improvements in the 2011 Ford lineup.
