2011 Ford Mustang V6

A 2011 Ford Mustang V6 has completed 1,457 laps (776.5 miles / 1250km), on a single tank of gas, at the Bristol Motor Speedway.

Exceeding all expectations, the Mustang averaged an amazing 48.5 mpg. To get this impressive figure, the driving team (which consisted of NASCAR’s David Ragan and four engineers) used a variety of fuel efficient techniques such as limiting use of the air conditioner and keeping engine revs low.

After 17 hours and 40 minutes, the Mustang finally ran out of gas – literally. In the end, the car posted an average speed of 43.9 mph (70.7 km/h).

According to Dave Pericak, the Mustang’s chief engineer, “To see a Mustang post average fuel economy of 48.5 mpg while running at Bristol is impressive. The new V6 engine along with the advanced six-speed transmission in the car is a key element in delivering both fuel economy and performance for Mustang.”
