DETROIT- Ford Motor Company is offering four new truck engines with six-speed automatic transmission as standard in the 2011 Ford F-150.

Each engine delivers improved fuel economy, outstanding performance and class-leading capability, according to the automaker. This versatile new powertrain lineup enables F-150 customers to choose the engine that best suits their needs.

Available at launch are a 3.7L V-6 and a 5.0L V-8, each with fuel-saving and performance-enhancing twin independent variable camshaft timing (Ti-VCT) technology, and a version of the 6.2L V8 that is the base engine in the 2011 Ford F-Series Super Duty.

A 3.5L EcoBoost engine, specially tuned and calibrated for the F-150, will be available in early 2011. With this engine, the F-150 will have up to 20 percent better fuel economy compared with the outgoing 2010 F-150.

"Our new engine lineup allows greater flexibility for customers to select the powertrain choice that best suits their needs," said Barb Samardzich, vice president of powertrain engineering. "We are in the midst of a powertrain revolution, with 30 new powertrains over the next two years."

Highlights of each new engine include:

3.7L four-valve Ti-VCT V6

• Best-in-class 300 horsepower (estimated) at 6,500 rpm.

• 275 lb.-ft. of torque at 4,500 rpm.

• Class-leading fuel economy.

• Best-in-class 6,100 lbs. maximum trailer tow.

• Ti-VCT creates precise, variable timing control of both the intake and exhaust camshafts to optimize power, performance and fuel economy.

• E-85 flex-fuel capability.

• Piston-cooling jets, which squirt oil on the underside of the pistons to keep the piston crowns cool under extreme operating conditions.

• Forged-steel crankshaft for improved durability.

5.0L four-valve dual-overhead-camshaft Ti-VCT V8

• Best-in-class 360 horsepower at 5,500 rpm and 380 lb.-ft. of torque at 4,250 rpm.

• Class-leading fuel economy.

• Best-in-class 9,800 lbs. maximum trailer tow.

• New strengthened block and new cylinder head optimized for performance and enhanced cooling.

• Unique intake camshafts, combined with Ti-VCT, composite intake manifold and optimized compression ratio for improved low-speed torque and towing capability.

• Forged-steel crank and all-new oil cooler enhance durability.

• Piston-cooling jets, which squirt oil on the underside of the pistons to keep the piston crowns cool under extreme operating conditions.

• E-85 flex-fuel capability.

6.2L two-valve single-overhead-camshaftV8

• Best-in-class 411 horsepower at 5,500 rpm and 434 lb.-ft. of torque at 4,500 rpm.

• Best-in-class 11,300 lbs. maximum trailer tow.

• Competitive fuel economy.

• Utilizes a large bore and shorter stroke. The large bore allows for larger intake and exhaust valves for improved engine airflow, and the short stroke allows higher engine speed for increased horsepower.

• Because of the large bore size, two spark plugs per cylinder are used to more efficiently burn the fuel-air mixture in the combustion chamber, enabling better fuel economy and increased engine torque. The twin plugs also help the engine maintain a smooth, stable idle, according to Ford.

• Used as the standard engine on the 2011 F-Series Super Duty, but tuned for the F-150 with a special cam profile. The engine will be standard on the 2011 F-150 SVT Raptor and other specialty applications, and pumps out up to 411 horsepower and 434 lb.-ft. of torque.

3.5L Ti-VCT EcoBoost

• Ti-VCT creates precise, variable timing control of both the intake and exhaust camshafts to optimize power, performance, and fuel economy.

• Fuel economy improves up to 20 percent versus 2010 model year F-150 5.4L V-8.

• Improved intake and exhaust camshafts optimized for improved fuel economy and performance.

• Cast exhaust manifolds for heavy-duty operation and durability.

• Improved manifold and cylinder heads for improved performance.

• Direct-acting mechanical bucket valvetrain with polished buckets to reduce friction and improve fuel economy.

The new engines for the Ford F-150 follow the all-new engine lineup for the 2011 Ford F-Series Super Duty introduced earlier this year and highlighted by the 6.7L Power Stroke V-8 turbocharged diesel, which delivers best-in-class torque, horsepower, and fuel economy, according to the automaker.
