2009 F-150 fuel efficiency details revealed

Image via WikipediaWe still don't know when it will officially go on sale (maybe in a month or so), but more details of the upcoming F-150 have been revealed, including fuel efficiency ratings. Ford is promising that it will be the most fuel efficient truck in it's class.

Using the tried-and-true fuel-saving techniques of lowering weight and improving aerodynamics, Ford claims the 2009 F-150 models will get, on average, 8%-better fuel economy than their 2008 predecessors. The SFE package will get as much as 21 mpg city with a V-8 engine, which, as full-size-truck drivers know, is a substantial improvement.

"Ford has committed to have the best or equal to the best fuel economy with every new product we introduce, and we are delivering with the new F-150," says Matt O'Leary, Ford F-150 chief engineer. "Fuel economy has moved from 10th to third place among pickup buyers' top purchase considerations -- right behind durability and value. The new F-150 delivers on all three as the industry leader."

To maximize your fuel economy with the F-150, you'll want to opt for the SFE package, which stands for "Superior Fuel Economy." The SFE package is available only on the F-150 SuperCrew XL and XLT 2WD models with the 5.5-ft beds. They'll come with a 4.6L three-valve V-8 that's been worked over to squeeze every last bit of efficiency out of it. It will feature a new technology called open-valve injection, which will allow the engine to run more spark advance at high engine speeds and loads and get the most efficiency out of each drop of gas. The engine will also use an aggressive fuel cutoff program that will cut fuel to the engine the instant you take your foot off the gas pedal and turn it back on when the engine reaches a low speed, or when you put your foot back on the gas.

Proprietary Ford software keeps the fuel cutoff and restart smooth, unlike, say, the fuel cutoff when you hit the rev limiter. The SFE also picks up a six-speed transmission, 3.15:1 rear-axle ratio and 18-in. chrome wheels with low rolling-resistance tires. The SFE's drag coefficient has been dropped to 0.403, 6% better than the 2008 F-150. All this is good for 15 mpg in the city and 21 mpg on the highway. Even with the small V-8 and low-ratio rearend, the SFE can still tow up to 7500 lb. The SFE package will be a no-cost option on SuperCrew XLTs, but will cost $1095 on SuperCrew XLs.

Across the entire 2009 F-150 lineup, Ford has switched to lighter-weight ultra-high-strength steel that shaves 100 lb off the curb weight. Every model also features improved aerodynamics, such as a reworked front valence that will improve airflow under the truck. Up top, the rear of the cab has been reworked to smooth out airflow over the bed, and a lip on the top of the tailgate helps direct airflow cleanly off the back of the truck. The larger 5.4L 3-valve V-8 in non-SFE-equipped trucks also gets open-valve injection for maximum power and efficiency, though it isn't clear whether non-SFE equipped trucks will get the six-speed automatic. The 5.4L-equipped trucks will tow up to 11,300 lb and can haul up to 3030 lb in the bed, the best in the class.

Delaying the new F-150 may have aggravated some that were anxiously awaiting it's arrival, but Ford has seemingly done the right thing by fine tuning the truck. With the economy in a state of flux and gas prices still rising, it will be important for the venerable F series to continue to enjoy some success. Even if it's long run as the best selling vehicle in America has finally come to an end.
