Ford's 1,000 lap challenge at Bristol Speedway involving the 2011 Mustang V6 is complete, and the miles per gallon average entered Prius territory.

When the folks at Ford Motor Company last set out to boast the impressive fuel economy of one of their new rides, they do so in a 2010 Ford Fusion Hybrid. At the time, the idea was to see how many miles they could log on a single tank of gas on public roads in the Washington, D.C., area.

When it was all said and done the fusion managed an impressive 81.5 miles per gallon, and traveled 1,445.7 miles on a single tank of gas. Not to be outdone in its own right, the new 2011 Mustang with its 3.7-liter, 305 horsepower V6 engine set out to reach its maximum range on a single tank of gas at Bristol Speedway. The 2011 Mustang V6 coupe, equipped with a six-speed automatic is officially rated at 19 city and 31 highway miles per gallon.

In order to achieve the best possible fuel economy, the V6 Mustang traveled at an average speed of 43.9 mph, including driver changes, and covered a total of 1,457 laps at Bristol Speedway. In total, 776.5 miles were traveled, resulting in an average fuel economy of 48.5 mpg - a new record for Bristol Speedway - and not too shabby for a 305 horsepower sports coupe.

Ford utilized five different drivers pilot the Mustang, four of which were Mustang team engineers, as well as Nascar driver David Ragan.
