Confirming one of the worst-kept secrets in the industry, Ford Motor Company announced today that its 2011 F-150 lineup will receive four new powertrains, ranging from a base 3.7-liter V6 to a pair of V8s and even a twin-turbocharged EcoBoost V6.
The F-150 was redesigned for the 2009 model year, but it made due with three rather outdated V8 setups, including two 4.6-liters and a 5.4-liter. Ford says that the 2011 lineup will offer more power, more refinement and better fuel economy.
All four of Ford’s new engines will be mated exclusively to six-speed automatic transmissions in the F-150. The 6R80 transmission gains Ford’s SelectShift system for full manual-style control to reduce upshifts. Gear ratios have also been modified and a one-way clutch is said to give the transmission smoother 1-2 or 2-1 shifts.
The 2011 F-150s will make their formal debut later this year at the State Fair of Texas’ auto show in September. The automaker hasn’t specified if there will be any cosmetic or suspension changes to go with the new V6s and V8s.
300-horsepower base V6
Ford dropped its base six-cylinder for the 2009 model year thanks to sluggish sales of its predecessor. Now, Ford thinks it has the right configuration for a base model. Taking the 3.7-liter Duratec V6 from the 2011 Ford Mustang, base variants of the F-150 will put out an impressive 300 horsepower (estimated).
That figure exceeds the horsepower output of all but the range-topping 2010 F-150.
Ford estimates 275 lb-ft. of torque at 4,000 rpm, meaning the powertrain won’t be best suited for customers who want to tow, however. Ford rates the 3.7-liter at up to 6,100 lbs. when properly configured.
5.0-liter V8
Ford’s truck engineers also looked to the 2011 Ford Mustang GT for its all-new 5.0-liter V8. Putting out 360 horsepower (at 5,500 rpm) and 380 lb-ft. of torque (at 4,250 rpm), the V8 has been modified significantly from its Mustang application.
Ford says that the camshafts were retuned for better low-end torque and that a 10.5:1 compression ratio helps reduce engine knock at low speeds for towing. The V8 uses an additional oil cooler to help give it 10,000 mile oil change intervals.
F-150s equipped with the 5.0-liter V8 and the proper towing configurations will be rated at an impressive 9,800 lbs. towing capacity.
Standard F-150 gains Raptor’s 6.2
Already available in the F-150 SVT Raptor, the automaker’s range-topping 6.2-liter V8 will make its appearance on the standard F-150 lineup.
Rated at 411 horsepower (at 5,500 rpm) and 434 lb-ft. of torque (at 4,500 rpm), the 6.2-liter helps the F-150 tow up to 11,300 lbs.
Ford says that the 6.2-liter will be available in certain “specialty applications,” like the recently-unveiled F-150 Harley-Davidson.
EcoBoost hits haulers
Already available in a number of Ford vehicles – like the Taurus SHO and Flex EcoBoost – the automaker twin-turbo, direct-injected 3.5-liter V6 will be a late-introduction offering on certain F-150 configurations.
Ford promises V8-like power with V6-level fuel economy, although the automaker hasn’t released specifics for either category. At any rate, look for horsepower near the Flex’s 355 ponies and torque somewhere around its 350 lb-ft. – which is spread from 1,500 rpm to 5,250 rpm thanks to the twin turbochargers.
As far as fuel economy, Ford suggests a 20 percent improvement over current F-150 5.4-liter figures, so figure around 16-17 mpg in the city and 24 mpg on the highway.
