DEARBORN, Mich., Feb. 25, 2010 – An all-new 6.2-liter V-8 gasoline engine, which has its roots in Ford Racing powerplants, joins the lineup for the 2011 Ford F-Series Super Duty.
The new 6.2-liter V-8 gasoline engine delivers 405 ft.-lb. of torque (at 4,500 rpm) and 385 horsepower (at 5,500 rpm) on regular gasoline. These numbers represent an increase of 40 ft.-lb. of torque and 85 horsepower over the current 5.4-liter V-8.
“Our all-new 6.2-liter V-8 engine uses race-proven components and technology that have been optimized for the high performance and efficiency that our Super Duty customers demand,” said Mike Harrison, Ford V-8 engine programs manager. “It delivers not only significantly better torque and horsepower than current heavy-duty gas engines, but also improved fuel economy.”
Already cementing its Built Ford Tough status
Nearly all the components of the 2011 Super Duty 6.2-liter V-8 are shared with the 6.2-liter V-8 engine found in the 2010 F-150 SVT Raptor, a purpose-built, high-performance off-road truck versatile enough to take on the most challenging desert adventures as well as the everyday commute. In November 2008, the 6.2-liter Raptor R not only survived the grueling Baja 1000, it earned a podium finish.
Core to the improvements is the adoption of an all-new engine architecture with increased bore spacing that allows better engine “breathing” in both the intake and exhaust for more power and more overall efficiency.
A closer look at how the new engine achieves its performance:
Performance heritage with proven durability and reliability
The concept of using a large-bore engine to make horsepower is part of Ford’s DNA, especially its racing heritage – the famous Ford Boss 302 and 351 engines, for example, pioneered many of the same concepts. Several racing projects proved out the performance, durability and flexibility of the new 6.2-liter V-8 engine architecture.
Testing on the 6.2-liter V-8 included running multiple engines for more than 500 hours at peak torque and peak horsepower, as well as customer-correlated 1,000-hour road load tests to ensure dependability for even the toughest Ford F-Series Super Duty customer.
All told, more than 50 engines were put through the dynamometer lab, running a variety of durability and development tests, undergoing extremes far harsher than can be expected – or duplicated – in the real world. Testing also included high-speed durability, crankshaft-torsional evaluation and engine thermal cycling, where the running engine is “shocked” from one coolant temperature extreme to the other.
“From the first test on the dynamometer, this engine was very reliable,” said Bob DeBona, supervisor, Engine Performance and Development. “The precision that went into the engineering and manufacturing of this engine led to very few tweaks to the block during development.
“Components such as the crank, connecting rods, heads and intake manifold stayed essentially the same throughout our durability testing, which is a testament to the reliability of this new engine. It’s able to pound out the torque, hour after hour, week after week, demonstrating extreme durability.”
The new 6.2-liter V-8 gasoline engine will be built at the Romeo (Michigan) Engine Plant.
