Drivers trained in mileage-maximizing techniques such as smooth acceleration and coasting to red lights were able to get an extraordinary 1,445.7 miles out of a single tank of gas during a fund-raising effort in Washington, D.C. that concluded April 28. They did it by averaging 81.5 miles per gallon in an off-the-showroom floor, non-modified 2010 Ford Fusion Hybrid, the most fuel-efficient midsize car in North America - nearly doubling its U.S. certified mileage.
The Fusion Hybrid 1,000-Mile Challenge started at 8:15 a.m. Eastern time on Saturday, April 25, from Mount Vernon, Va., and ended April 28 at 5:37 a.m. on George Washington Parkway. After more than 69 continuous hours of driving, the Fusion Hybrid finally depleted its tank and came to a stop with an odometer reading of 1,445.7 miles - setting a world record for gasoline-powered, midsize sedan.
The challenge team, which included NASCAR star Carl Edwards, high mileage trailblazer Wayne Gerdes and several Ford Motor Company engineers, raised more than $8,000 for the Juvenile Diabetes Research Foundation (JDRF) by exceeding the goal of 1,000 miles on a single tank of gas. The Fusion Hybrid's official estimated range is approximately 700 miles per tank.
A team of seven drivers prepared for the challenge by learning a few mileage-maximizing techniques, most of which can be used in any vehicle to improve fuel economy, but are especially useful in the Fusion Hybrid where the driver can take advantage of pure electric energy at speeds below 47 mph.
CleanMPG.com founder Wayne Gerdes, an engineer from Illinois who coined the term "hypermiling" to describe the mileage-maximizing techniques, provided the pointers. They include:
- Slowing down and maintaining even throttle pressure;
- Gradually accelerating and smoothly braking;
- Maintaining a safe distance between vehicles and anticipating traffic conditions;
- Coasting up to red lights and stop signs to avoid fuel waste and brake wear;
- Minimize use of heater and air conditioning to reduce the load on the engine;
- Close windows at high speeds to reduce aerodynamic drag;
- Applying the "Pulse and Glide" technique while maintaining the flow of traffic;
- Minimize excessive engine workload by using the vehicle's kinetic forward motion to climb hills, and use downhill momentum to build speed; and
- Avoiding bumps and potholes that can reduce momentum
In addition, it is important for Fusion Hybrid drivers to manage the battery system's state of charge through the use of regenerative braking and coasting, and balancing the use of the electric motor and gas engine in city driving to avoid wasting fuel.
Fusion Hybrid drivers also can stay more connected to the hybrid driving experience with Ford's SmartGaugeTM with EcoGuide, a unique instrument cluster that helps coach drivers on how to optimize performance of their hybrid.
The Fusion Hybrid 1,000-Mile Challenge team took turns driving several routes in and around the national capital over the course of approximately three days and nights. The route involved elevation changes, and ranged from the relatively open George Washington Parkway to a 3-mile stretch in the heart of the city that is clogged with roughly 30 traffic signals.
Ford NASCAR star Carl Edwards took time away from the high speed world of professional car racing to contribute to the Fusion Hybrid team's success in D.C.
"It was exciting to be an active part in this challenge. The fact that it will help spread the word about the Fusion Hybrid's great mileage, and help out a great charity, makes it even more special," said Edwards, whose '99' team has used fuel-saving techniques to win races. "There's no question that the Fusion Hybrid will help consumers save fuel when they drive it. Having driven the car, I feel strongly about how great it is - so strong that I've purchased
