Ford has been tight-lipped with the details of the 3.5L EcoBoost V6 intended for the 2011 F150 but there is a variety of information that we do know. Unfortunately, Ford has not stated an exact set of performance numbers or economy figures but they do hint to the twin turbocharged V6′s abilities. Keep in mind that this engine is used in the 2010 Ford Taurus SHO with 365 horsepower and 350 lb-ft of torque, but with the EcoBoost V6 listed as the “premium engine” for the 2011 F150, I would expect to see more torque if not more horsepower and torque. Considering the fact that the 6.2L V8 is only available in the high performance Raptor and Harley Davidson F150 models, the 3.5K EcoBoost V6 would only need to be in the range of 400 horsepower and 390 lb-ft of torque to proudly claim the spot as the premium engine option for the 2011 F150.
Much like the entry level 3.7L V6 and the 5.0L V8, the 3.5L EcoBoost V6 in the 2011 F150 uses Ford’s twin independent variable camshaft timing (Ti-VCT) system to maximize performance while also achieving the best possible fuel economy. The actual economy numbers will not be available until later this year but Ford has stated that the EcoBoost V6 in the F150 will offer a 20% improvement over the outgoing 5.4L V8. The Triton 5.4 offers 14mpg around town and 20mpg on the highway so a 20% improvement would allow the EcoBoosted 2011 F150 to get somewhere in the area of 17mpg around town and 24mpg on the open road. Also, the 2010 F150 powered by the Triton 5.4L V8 offers only 310 horsepower and 365lb-ft of torque; so even if there was almost no change in the power ratings from the Taurus SHO to the 2011 F150, the new models with the EcoBoost V6 would have a vast advantage in power.
Like the other new engines for the 2011 Ford F150, the 3.5L EcoBoost V6 uses an aluminum cylinder head and block design, as well as an aluminum oil pan. A forged steel crankshaft helps to handle the power of the 3.5L EcoBoost while also dealing with the abuse of pickup use, and a piston cooling jet system helps to keep the engine running cool even under the worst of conditions.
