Coupled with a six-speed automatic anismission, the 365hp twin-turbo produces best-in-class 420 lb-ft (569 N·m) of torque, enabling best-in-class maximum towing of 11,300 pounds (5,126 kg) and maximum payload of 3,060 pounds (1,388 kg).

The 3.5-liter EcoBoost is the final piece of the most extensive powertrain makeover in the 63-year history of Ford F-Series. Introduced earlier and now available are a new 3.7-liter V6, a 5.0-liter V8 and a 6.2-liter V8. Each of these engines also offers a combination of good fuel economy, power and capability.
Each engine is mated to a fuel-saving six-speed automatic transmission—making Ford the only manufacturer to equip its entire full-size pickup lineup with standard six-speed automatic gearboxes. All 2011 F-150s, except those equipped with the optional 6.2-liter V8, feature EPAS (electric power-assisted steering), a segment first. EPAS contributes about a 4% fuel-economy benefit compared with conventional hydraulic systems.
By 2013, Ford plans to offer an EcoBoost engine in up to 90% of its North American nameplates, supporting global sales of 1.5 million EcoBoost-powered vehicles per year.
As with diesels, today’s EcoBoost engines feature:
- Turbocharging to create a more dense mix of air and fuel in each cylinder;
- Special pistons with optimized bowls in the center to improve combustion efficiency. These pistons are also oil-cooled, which reduces in-cylinder temperatures; and
- Reduced CO2 emissions and higher fuel economy.
Like diesels, Ford’s EcoBoost engines deliver solid performance and driving enjoyment at all speeds. EcoBoost accomplishes this at less cost than a similar-displacement diesel engine.
