Back in March Ford announced that they’ve set themselves a challenge to prove the new 3.7 liter V6 engine which powers the 2011 Mustang is as much about fuel efficiency as it is about performance. The goal was to do a 1000 laps of Bristol Motor Speedway track on a single tank of fuel. They’ve done it, and much to the surprise of anyone the Mustang way passed the target by doing 1,457 laps and averaging 48.5 mpg!
Of course that 48.5 mpg record has been achieved by driving consistently on a track with average speed of 43.9 mph. The real life economy of the V6 Mustang is 31 mpg which is still very impressive considering that it delivers 305 hp. We’d just like to say well done to Ford and all those drivers who tolerated hours hours of mind-numbingly boring consistent economy driving to set this record!
“To see a Mustang post average fuel economy of 48.5 mpg while running at Bristol is impressive,” said Dave Pericak, Mustang chief engineer. “The new V-6 engine along with the advanced six-speed transmission in the car is a key element in delivering both fuel economy and performance for Mustang.”
Ford is committed to being a fuel economy leader in every segment it competes in and Mustang’s leads in its class along with other Ford fuel economy leaders like the Ford Fiesta, Fusion Hybrid and new Lincoln MKZ Hybrid, America’s most fuel efficient luxury sedan.
The Challenge team, which included NASCAR star David Ragan and four Ford Mustang engineers, completed the challenge in 17 hours and 40 minutes, showing off the 2011 Mustang V-6’s class-leading fuel economy by averaging 48.5 mpg over the course of the 776.5 miles logged during the Challenge. That distance is more than the two complete NASCAR Sprint Cup events that take place in Bristol every year.
Ragan pushed the Mustang past the 1,000-lap mark at 7:26 p.m., 12 hours and 26 minutes into the Challenge, but the car wasn’t close to being out of fuel. Mustang engineer Seong Park was behind the wheel when it finally came to a halt (on the backstretch) of the famed NASCAR track at 12:41 a.m. local time.
Other Mustang Challenge team drivers included Tom Barnes, Jonathan Mehl and Carl Ek, who along with Park, rotated through one-hour driving stints during the event, which took place at the world’s fastest half-mile track.
“When we hit 1,000 laps we still had a quarter of a tank of gas left,” said David Ragan, driver of the No. 6 UPS Ford Fusion for Roush Fenway Racing, and the man who drove the 2011 V-6 Mustang past the 1,000 lap mark. “The last driving stint before I passed 1,000 laps I was averaging 43.7 miles a gallon and that is unbelievable. These guys have run the distance of more than two Sprint Cup races at Bristol and they still have fuel left. Congratulations to everyone behind the Mustang and to everyone at Ford, because this 2011 Mustang V-6 is really something special.”
A team of Ford engineers prepared for the challenge by implementing fuel efficient driving tips like minimizing the use of air conditioning, steady and consistent driving, avoiding sudden stops/starts and by keeping the RPMs low. The engine in the Mustang is powered by a lightweight, all-aluminum 3.7-liter dual-overhead-cam (DOHC) V-6 engine that uses advanced engineering to deliver its combination of power and economy. Twin independent variable camshaft timing (Ti-VCT) adjusts the valve train in microseconds depending on driver inputs, further contributing to the engine’s overall efficiency. The Mustang used in the challenge is a stock production vehicle that can be purchased through a Ford dealer.
“This is beyond our wildest dreams,” said Tom Barnes, the lead engineer for the Ford Mustang 1,000 Lap Challenge. “There have been a lot of people who have done a lot of things in preparing this 2011 Mustang V-6 to run the Mustang 1,000 Lap Challenge and have the success we have had today. It was great when we went past the 1,000 lap mark with David, but nobody could ever imagine that we still had five hours ahead of us. This is a fantastic feeling and it shows again what a great car the 2011 Mustang V-6 is.”
