How To Drive For 100 MPG
A Driving Expert Shows You How to Save Fuel (and Money)
Posted: Oct, 28 2009
by: Rex Roy | AOL Autos

We first met Gil Portalatin -- a 25 year veteran at Ford -- in Los Angeles when testing the 2010 Fusion Hybrid. In a fuel-economy competition against the media, Gil (an engineer by trade) effortlessly triumphed by racking up economy numbers that significantly bested the journalists and EPA estimates. On some runs, Gil's Fusion returned nearly 47 mpg. We immediately wanted to know Gil's fuel economy secrets so we could tell them to you. While 100 MPG might sound like an incredible number, it's not impossible. And even if you use a portion of Gil's advice, you'll immediately improve your mileage and save money. Most cars could see mileage well above 50 MPG and even up to 100 MPG with the right driver.

To learn Gil's special driving techniques, we visited his group's modest offices in Dearborn, Michigan, the city Henry Ford (founder of Ford Motor Company) put on the map. After a brief interview that covered technical aspects of Ford's new hybrid technologies as well as touching on a running dispute with Toyota, we went for an instructional drive.

The 2010 Ford Fusion Hybrid
In case you missed our coverage from the 2008 Los Angeles and 2009 Detroit Auto Show, teams of skilled engineers in and around Detroit are creating great products. Yes, really. Some would have you believe that Detroit is incapable of engineering a tissue box let alone a competitive modern car, but those people are wrong.

Proof comes in the form of the 2010 Ford Fusion Hybrid, a car that demonstrates active minds are working on great cars in Detroit. The crisply styled sedan is rated at 41 mpg city, 36 mpg highway. For the record, the Fusion bests the Toyota Camry Hybrid by 8 mpg around town and 2 mpg on the highway. While hundreds of individuals contributed to the new Fusion Hybrid, Portalatin is the point man for Ford's hybrid vehicles.

According to Gil, whose official title is Hybrid Propulsion System Applications Manager, getting good mileage out of any vehicle goes well beyond maintenance basics like making sure your tires are aired up. Gil believes that the driver is the key to great mileage. (Drivers control the car, not the other way around.) Following Gil's advice will help improve the mileage in any car, not just in hybrids. However, Gil also has special tips just for them.

Tip 1: Easy on the throttle, then glide.
Gil says, "Most people accelerate way too hard from a stop. This wastes huge amounts of energy. You'll get much better mileage accelerating gently up to the speed limit. Once you're at the limit, then you need to glide." By this, Gil means releasing most of the pressure on the accelerator so you're using the bare minimum amount of power to maintain your speed. In most cars, this will enable the automatic transmission to shift into its highest, most efficient gear.

Tip 2: Anticipate traffic.
"I watch people drive and waste gas every day," Gil observed. "Most drivers don't pay attention to the flow of traffic. If you're in traffic, you know you're going to stop again, so anticipate that stop by easing off the accelerator pedal early and coasting as much as you can. Looking way down the road helps you anticipate traffic flow because you can see when traffic lights are going to change and how other cars are behaving." Gil knows that this driving technique won't put you in the pole position at every traffic light, but your mileage will go up, as will the life of your vehicle's braking system components.

Tip 3: Slow down on the highway.
"I drive 50 miles each way to work," Gil explained, "so I've had plenty of time to study and test techniques for getting the best highway fuel economy." The advice is not complex. "People just have to slow down," Gil noted. "Unless you work in an aerodynamic lab, you don't understand how much more energy it takes to push a car through the air at 75 mph than at 65 mph, but it's huge." During our drive, Gil went on to note that most cars have a "sweet spot" of efficiency between 65-70 mph, so you don't have to drive at snail-like speeds to improve your mileage, although driving between 55-65 mph will improve mileage even further.

Tip 4: Drive with the terrain, and drive smoothly.
"It takes more energy to climb a hill than roll down the other side," Gil said, pointing out the obvious. "So when you're on the highway, it's OK to lose a few miles per hour when you're driving up an incline. You can regain the lost speed when you head down the other side." While this tip may seem easy, it requires constant attention. "Some drivers will be better off just driving with their cruise control," he said. "This helps those drivers who are constantly on and off the accelerator. That kind of throttle control kills mileage. A smooth, steady accelerator pressure is much greener, regardless of the speeds you travel."

Hybrid Tip 1: Don't accelerate too slowly.
"This is something that trips up hybrid drivers; in their excitement to use only battery power, they accelerate too slowly from a stop. While super-gentle acceleration keeps the vehicle in electric-only mode, it also drains the batteries quickly, often causing the gasoline engine to come on just to recharge the battery pack." Instead of accelerating so slowly, accelerate with a bit more vigor, and then lift off the throttle. Once at speed (up to nearly 50 mph in the Fusion Hybrid), the gasoline engine will often shut completely off, leaving propulsion to the battery powered motor to maintain cruising speed. This technique yields maximum mileage.

Hybrid Tip 2: Keep the batteries charged.
All hybrids have two fuel tanks; one holds gasoline and the other electrons (the hybrid battery pack). Both "tanks" need to be kept full to go the farthest distance, but the process for filling up on electrons is a bit different than stopping at the gas station. "Coasting and gentle braking are the fastest and most efficient way to recharge your hybrid's batteries," Gil said. "On our Fusion, you can see by the gauges that when you coast or apply the brakes that the hybrid system is using the car's kinetic energy to recharge the batteries. The longer you can coast or gently slow down, the more energy you can store. Keeping the batteries above 50-percent full extends the distance you can run on battery power, saving fuel."

Ford versus Toyota -- The Hybrid Technology War of Words
There's a rumor going around that Ford is using Toyota-patented technology in their hybrid vehicles. The insinuation is that Ford is incapable of engineering their own competitive hybrid, so they are using Toyota's. According to Gil -- and this represents the official Ford Motor Company stance -- the rumor is completely untrue.

"When we started developing our hybrid system, it was the normal course of business to do a patent search," Gil explained. "We realized that some of our ideas might infringe on Toyota's hybrid patents. We contacted them. It just so happened that Toyota was developing some diesel engine technology that might infringe on existing patents owned by Ford. The companies decided to allow the patent infringement as kind of a trade."

Interesting that Ford and Toyota had a patent swap... Looks like Toyota got the **** end of that trade, hahaha

haha, yeah, I forgot about that. Doesn't seem to be affecting Ford, since they're posting surprise profits!

That's really how you should be, lol. If you buy a mustang, especially a v8, you shouldn't make gas mileage a primary concern. If mileage is that big an issue...buy a more economical car, like a prius

The 2011's with the new engines are claiming improvements in mileage, especially the v6, but I wouldn't be disappointed if they didn't reach those goals. ..it's a mustang.
