First Look: 2011 Ford F-150 Powertrain
Looking for major changes? Just pop the hood.

Yes, it's possible to sell full-size pickups on sheer bravado and brand loyalty, but it seems most buyers are looking for a little something extra: fuel economy. Believe it or not, Ford says nearly 70 percent of all full-size truck buyers would like to see an improvement in fuel consumption -- and amazingly, nearly 32 percent of the diehard, badge-loyal buyers surveyed would jump ship to another brand to cut their fuel consumption.

Fear not, Ford fans. For 2011, the F-150 is blessed with an all-new lineup of engines, many of which are designed to offer more power while simultaneously reducing the pain felt at the gas pump.

2011 Ford F 150 V 6 Engine
Base Engine? Six Cylinders, Not Eight
To start, an eight-cylinder engine is no longer the base engine. While entry-level 2010 F-150s used the aging 4.6-liter, two-valve V-8, that engine is superseded by a 3.7-liter, DOHC V-6.

First launched in the 2011 Mustang, the aluminum-block six-cylinder features twin independent camshaft timing, and has been slightly re-tuned -- notably in its intake and exhaust systems - to be less rev-happy and more towing-friendly. The truck-tuned 3.7-liter is rated at 300 horsepower at 6500 rpm and 275 pound-feet of torque at 4500 rpm, a slight drop from its Mustang-spec form, which was rated at 305 horsepower and 280 pound-feet. It is, however, comparable to the old two-valve 4.6-liter V-8, which cranked out 248 ponies and 294 pound-feet of torque. In two-wheel-drive, regular cab trucks, the 3.7 reportedly is capable of towing as many as 6100 pounds.

Don't expect this engine choice to be limited to stripped-down work trucks. All two-wheel-drive XL, STX, and XLT models will carry this engine as standard equipment, regardless of cab choice or bed configuration.

Big Five-Oh
UUnsurprisingly, another Mustang engine worms its way into the new 2011 F-Series, albeit with a few tweaks. The vaulted 5.0-liter, DOHC V-8, launched in the 2011 Mustang GT, is available in virtually every F-150 trim between the XL and Platinum lines. For the most part, the engine is identical to that used in the pony car, but slight revisions -- including re-tuned intake camshafts, decreased compression, and an additional oil cooler -- shift its output in favor of delivering more low-end torque.

In F-150 form, the 5.0 churns out 360 horsepower at 5500 rpm, and 380 pound-feet of torque at 4250 rpm. That's a little less than the 412 horsepower and 390 pound-feet offered in the Mustang, but most truck drivers like will appreciate a broad, flat torque curve. Regardless, those figures are still a substantial upgrade compared to last year's mid-grade V-8 (the three-valve 4.6-liter was rated at 292 horsepower and 320 pound-feet of torque), but it also knocks on the door of 2010's premium engine, the 5.4-liter Triton V-8 (320 horsepower, 390 pound-feet of torque). ... index.html
