What happens when you mix a group of die-hard Ford engineers, a renowned oval track, and a bone-stock 2011 Ford Mustang V6?  You get some fine folks out to make a mark in history and put their hooves to the pavement, making history for the legendary pony car.  Most of the time, a Ford Mustang rider is out for pure speed, cornering, lap times, or straight-line bursts of adrenaline.  This time, on June 23rd, 2010, a team of Ford fanatics were out for one thing and one thing only; economy.  Wait.  What?

Yes, the 1,000 mile lap challenge held at Bristol Motor Speedway in Tennessee pitted a base 2011 Mustang against, who else, but itself and its own design & engineering specifications.  The goal: see just how far the V6 Mustang could go on just one tank of fuel.  Well, after over twelve and a half ours after the green flag, the Mustang covered 1,457 laps with an average speed of 43.9 mph and the 16-gallon fuel tank was sipped at a miserly 48.9 mpg.  That’s right, folks–the new Mustang V6, sporting 305hp, was able to eek out compact and sub-compact fuel economy numbers…in a sterile environment.  Either way, who cares?  This just goes to show how well Ford and its team have it together in this latest pony car installment.

MUSTANG V-6 AVERAGES 48.5 MPG; RUNS 1,457 LAPS AT BRISTOL ON A SINGLE TANK OF GAS

* The 2011 Ford Mustang V-6 sets a new record by averaging 48.5 mpg on a track while completing 1,457 laps with an average speed of 43.9 mph
* Mustang is powered by a new 3.7-liter V-6 engine that uses advanced engineering and technology to deliver great performance and fuel economy
* More than 51,000 entries were received for the Mustang 1,000 Lap Challenge with 22 entries guessing the winning number of laps
* A team of five drivers, including four Ford Mustang engineers and Ford NASCAR star David Ragan, drove the Mustang during its record run

BRISTOL, Tenn., June 24, 2010 – The 2011 Ford Mustang, which made history when it became the first car ever to deliver more than 30 mpg and 305 horsepower, has set a new record by running 1,457 laps at Bristol Motor Speedway while averaging 48.5 mpg.

The Mustang 1,000 Lap Challenge was designed to demonstrate that a stock production Mustang V-6 could run 1,000 laps and 533 miles on a single of tank of fuel. With the aid of fuel efficient driving techniques by Ford engineers, the Mustang far surpassed its goal of 1,000 laps.

“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.”
