For the 2011 model-year, the Ford F-150 received the most extensive powertrain overhaul in the truck's history. The 2011 F-150 has four new truck engines, all coupled to a revised six-speed automatic transmission.
Available are a 3.7L V-6 and a 5.0L V-8, each with fuel-saving, performance enhancing twin independent variable camshaft timing (Ti-VCT) technology, and a version of the 6.2L V-8 that is the base engine in the 2011 Ford F-Series Super Duty. A 3.5L EcoBoost truck engine, specially tuned and calibrated for the F-150, will be available in early 2011.
Ford says the 2011 F-150 lineup delivers best-in-class fuel economy. The 3.5L EcoBoost engine that will be added to the engine lineup in early 2011 will support an up to 20-percent fuel economy improvement for the 2011 F-150 in comparison to the outgoing 2010 F-150.
Extensive Testing Program to Ensure Truck Application
To ensure the highest quality and most reliable engines, Ford engineers studied the warranty history of the outgoing engines and developed testing procedures based on the real-world driving experiences of current F-150 drivers.
Prototype engines underwent a wide range of tests to ensure complete compatibility with truck application and truck durability, with all components and systems passing testing to the equivalent of 150,000 miles. Components such as the exhaust manifolds and the crankshaft (forged steel) were upgraded, piston-cooling jets and oil coolers were added, and engines were specifically calibrated for improved heavy-duty operation and durability in F-150.
