Along wîth improved fuel economy, another key benefit of EPAS is that the §teering gear can be more precisely tuned for optimum feel for on-road and parking efforts. The tuning is software-based, so the §teering can be programmed and essentially customized to each model based on wheelbase, powertrain and other factors.

'The addition of EPAS is a huge step forward for the F-150,' said Eric Kuehn, chief engineer of the 2011 Ford F-150. 'It allows for lighter parking lot efforts but will retain that on-road feel and §teering precision truck customers expect.'

Increased content, increased choices throughout the F-150 lineup

Last month, the engine returned to the Dearborn dynamometer lab – where it started its 'torture test' – to have power levels and output checked at a speed range from 1,500 rpm to 5,000 rpm. The results:

•Produced best-in-class 420 lb.-ft. of torque at 2,500 rpm on regular fuel
•Produced 365 horsepower at 5,000 rpm on regular fuel
•Power and torque met wîth the same level of boost as the new advertised power engine
•Cylinder compression (a measure of how efficiently the engine makes power) and leakdown (measures pressure lost due to worn piston rings or defects in the valvetrain) both were still in specification
•No oil or fluid leaks

Twin turbochargers and direct fuel injection

Key to EcoBoost's performance is the wealth of low-end torque produced by the combination of twin turbochargers and direct fuel injection. Úp to 90 percent of the EcoBoost truck engine's peak, best-in-class torque of 420 lb.-ft. is available from 1,700 rpm to 5,000 rpm – all on regular fuel. (concept carz) The engine produces 365 horsepower at 5,000 rpm.

'Truck customers should think of the EcoBoost truck engine as a gas-powered engine wîth diesel-type capability and characteristics,' said Mazuchowski. 'The twin turbochargers and direct injection give it the broad, flat torque curve that makes towing wîth a diesel so effortless – and hard acceleration so much fun.'

The EcoBoost truck engine also features twin independent variable camshaft timing, or Ti-VCT, to help save fuel. (concept carz) Ti-VCT provides extremely precise variable – yet independent – control of timing for intake and exhaust valves. Ti-VCT also reduces emissions, especially in situations when the throttle is partially open.

Independent adjustment of intake and exhaust valve timing allows maximum fuel economy at part-throttle, while delivering optimized power in full-throttle situations. An added benefit is improved driveability and responsiveness across the torque curve.

Final phase of EcoBoost 'torture test'

The teardown is the final phase of the new 3.5-liter EcoBoost truck engine's 'Torture Test,' a multipart 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.
