Trio of 2009 F-150 engines offers power and better fuel economy
The new F-150 is powered by three modern V-8 engines, mated to either a 4-speed or a new fuel-efficient 6-speed automatic transmission. The engines include:
- 5.4-liter, 3-valve Triton V-8, which has been optimized for better performance with improved horsepower and torque and is capable of running on E85 (85 percent ethanol and 15 percent gasoline), pure gasoline or any blend in between.
- 4.6-liter, 3-valve V-8, which is new for F-150. Both the 5.4-liter and 4.6-liter 3-valve V-8's utilize open valve injection. This unique feature improves the flow of fuel into the combustion chamber, which results in an increase in horsepower during towing and reduced emissions.
- 4.6-liter, 2-valve V-8, a third V-8 choice in the line-up that delivers more horsepower with the same fuel economy performance as the outgoing truck's V-6.
This all-V-8 engine lineup delivers a fleet-average 1 mpg improvement in fuel economy versus the outgoing F-Series. Diesel and EcoBoost gas turbo direct injection engines are planned for F-150 in 2010, as well.
Towing and hauling: The new 2009 Ford F-150 will feature class-leading towing and hauling capability made possible by the stronger and lighter frame. All internal components of the smooth-shifting 6-speed transmission have been upgraded to handle the higher torque capacities, including more robust clutch packs, bigger pump and bigger output shaft. The transmission's hydraulic system was also beefed up to enable improved idle speeds and improved converter clutch duty cycles.
