The Ford Mustang is the original pony car, dating back to the spring of 1964. With millions sold over the years, the Mustang means a lot of things to a lot of folks … but few speak of the Mustang with fuel economy and performance in the same breath. While a relatively fuel-efficient four-cylinder engine was offered in the Mustang for model years 1974 through 1993, its performance was less than awe-inspiring. The Mustang’s gas mileage ratings may have topped 30 MPG for the four-cylinder engine models, but they weren’t much fun off the line.
Flash forward. Ford made a big change with the 2011 model year, with a new 3.7-liter V6 engine that is smaller, more fuel-efficient and markedly more powerful than the outgoing 4.0-liter V6 engine. To commemorate the event, they took the new model to the racetrack to prove a point. The goal: put the new V6 Mustang to the test to see how many miles could be coaxed out of one tank of gas under ideal conditions.
