NEW F-150 ENGINES
In addition to the new 6.2-liter, several other powerplants are coming. The 2011 model-year F-150 will offer four new engines. The smallest, a Duratec 3.7-liter V-6, has also been seen in the 2011 Edge. Its estimated 300 horsepower and 275 pound-feet of torque are higher than those of both the Ram 1500 and Silverado/Sierra 1500 sixes and comes backed by a six-speed automatic, where the competitors have four-speeds. At that horsepower level, the Ford 3.7's power approaches what the base V-8 Rams and Chevrolets offer. It also has 52 more horsepower than the two-valve 4.6-liter V-8 and 6 more pound-feet. The engine has variable timing control of the intake and exhaust camshafts (Ti-VCT), piston-cooling jets, and forged-steel crankshaft, and is E85 compatible. Ford expects this will have best-in-class fuel economy. F-150s equipped with this engine can tow up to 6100 pounds.
The 5.0-liter V-8, which is very close to the 5.0-liter engine of the 2011 Mustang GT, is also equipped with Ti-VCT. This DOHC eight has a power output of 360 horses and 380 pound-feet of torque. That's 68 more horses than the three-valve 4.6-liter, available 200 rpm sooner, and 60 pound-feet more torque with a peak rpm that's now 250 higher. Even though this engine is a lot like the one in the Mustang, the F-150 application comes with another oil cooler and cast exhaust manifolds. Other features include a forged-steel crank and E85 capability, and its compression ratio goes from 11:01 in Mustang to 10.5:1 in the 5.0-liter F-150 to reduce knock at lower speeds while towing. These numbers are higher than those of the Ram's 4.7-liter V-8, Chevrolet's 4.8-liter, and Chevrolet's 5.3-liter. The 5.0-liter can tow as much as 9800 pounds and is also backed by a six-speed automatic.
