DEARBORN, MI - The 2011 Ford F-150 EcoBoost recently logged some tough miles in rugged Pacific Northwest country in the latest demonstration of its durability.

The new 3.5-liter EcoBoost "torture test" truck engine moved from the lab to the outdoors with a stop at a logging company in Oregon. It's the current phase of a multi-part series of Web-based documentaries that began when this randomly selected EcoBoost engine endured the equivalent of 150,000 miles or 10 years' use on the dynamometer, replicating the duty cycle of the harshest-use customer.

After the dyno torture testing, the engine was dropped into a new 2011 Ford F-150 to work as a log skidder for Nygaard Logging of Warrenton, Ore. Skidding is the process of moving harvested timber, after the branches have been removed, from the forest to a staging area where it is placed on a truck to be sent to a sawmill.

The 2011 Ford F-150 EcoBoost replaced a vehicle similar to a backhoe that "ropes" the harvested timber using high-strength cables and drags it to the staging area.

The work was performed at Clatsop State Forest, where the 2011 F-150 EcoBoost pulled logs weighing from 4,000 to 9,000 pounds. That's where the new engine's best-in-class torque of 420 lb.-ft. at 2,500 rpm was essential - especially low-end torque. Up to 90 percent of the EcoBoost truck engine's peak torque is available from 1,700 rpm to 5,000 rpm - all on regular fuel.

The EcoBoost truck engine also delivers best-in-class maximum towing capability of 11,300 pounds.

"Each of these real-world tests demonstrates the durability and reliability that is designed, engineered and manufactured into our new EcoBoost truck engines - and all our truck engines," said Eric Kuehn, chief engineer of the 2011 Ford F-150. "This work in particular demonstrates the outstanding low-end torque the EcoBoost truck engine delivers."
