- The 2010 Ford F-150 SVT Raptor delivers a new 6.2-liter engine with 411 horsepower and 434 ft.-lb. of torque, powering customers through almost any off-road terrain they encounter
- The engine and truck were tested in the Baja 1000 and on a uniquely designed desert loop to prove out the durability demanded by high-performance, off-road enthusiasts
- Core features of the new 6.2-liter engine include cast-iron engine block and four-bolt main bearing caps, aluminum cylinder heads, a single overhead camshaft with roller-rocker shaft drivetrain and dual-equal variable cam timing
DEARBORN, Mich., May 13, 2010 – The Ford F-150 SVT Raptor already has proven itself as a one-of-a-kind high-performance truck. Now, the introduction of an optional 6.2-liter V-8 engine offers customers even more power for their off-road adventures.
With 411 horsepower and 434 ft.-lb. of torque, the new engine makes the F-150 SVT Raptor the most powerful half-ton pickup on the market, and gives customers new levels of capability. Low-speed maneuvers, such as rock crawling, driving up a grade or accelerating through deep sand, require much less throttle input because of the increased torque. The exhaust for the 6.2-liter engine was uniquely tuned to deliver the performance-oriented, high-horsepower sound customers want. Additionally, a unique firing order gives the 6.2-liter a distinctive roar.
The 6.2-liter engine is unique from the 5.4-liter engine that launched with the F-150 SVT Raptor. Everything from the block to the cylinder heads is new, giving Ford engineers a clean-slate approach to a new architecture. A revised off-road mode transmission calibration on the 6.2-liter holds gears longer for improved high-performance off-road driving and makes the throttle response more linear so that off-road driving is easier.
The 6.2-liter V-8 engine is the same engine used in the all-new 2011 Super Duty, but with unique tuning and a unique cam profile to produce more horsepower and torque. It's similar to the race-prepped engine that powered Raptor R to a podium finish at the 41st Tecate SCORE Baja 1000 in 2008 and completed every mile of the 2009 Best in the Desert series.
Testing in the heat
The engine was put to the test in its element – the desert of Borrego Springs, Calif. Important factors such as engine cooling were tested on the 62-mile loop designed by Ford's Special Vehicle Team.
"We spent a lot of time developing our desert durability test so that it's very close to replicating the Baja 1000," said Kerry Baldori, SVT chief functional engineer. "Desert testing proved to be a very quick way to learn about the reliability of the truck and it put another level of extreme loads on the engine that our normal durability testing doesn't cover."
Engine cooling is key on Raptor – when the truck is in a desert environment, the hot weather and deep sand put a heavy load on the vehicle and the engine has to exert maximum power to keep it going through deep sand.
There also is more airflow through the radiator at low speeds, and a large and effective cooling system is required for this extreme environment. To improve airflow to the engine, grille openings were increased by 20 percent.
Features of the new 6.2-liter V-8 engine include:
- Cast-iron engine block with bay-to-bay breathing and four-bolt main bearing caps with additional cross bolts for durability
- Aluminum cylinder heads, with two valves per cylinder and two spark plugs per cylinder to more efficiently burn the fuel-air mixture in the combustion
- Single overhead camshaft with roller-rocker shaft drivetrain, which creates a stiff valvetrain that allows optimized camshaft lift profiles and results in better low-speed torque. The roller-rocker shafts allow valve angles to be splayed, resulting in optimized intake and exhaust port layout for better engine breathing
- Dual-equal variable cam timing means intake and exhaust valve opening and closing events are phased at the same time to optimize fuel economy and performance throughout the engine speed range and throttle positions
Core to the improvements is using a larger bore and shorter stroke. This approach to creating power has its roots in storied Ford racing engines from the past. The large bore (102 millimeters) allows for larger intake and exhaust valves for improved engine breathing, and the shorter stroke (95 millimeters) allows higher engine speed for increased horsepower. Still, peak horsepower is generated at a relatively modest 5,500 rpm. Piston-cooling jets squirt oil on the underside of the pistons to keep the piston crowns cool under extreme operating conditions.
Crankcase breathing is also improved to reduce windage losses and oil aeration levels at very high speeds. "That really helps get a robust lubrication system for the engine," Baldori said. "It allows us to endure a lot of time at extreme high speeds."
The 6.2-liter-equipped F-150 SVT Raptor is now available at Ford dealers nationwide. There is tremendous demand for Raptor with the 6.2-liter engine – with sales rates three times that of the base F-150. Since announcing the 6.2-liter, more than 3,000 orders have been placed. MSRP for the 6.2-liter F-150 SVT Raptor starts at $41,995 including destination and delivery.
