Auto Car | Ford GT 2005 | The Ford GT is driven by an all-new, mid-engined powertrain producing 500 horsepower and 500 foot-pounds of torque. The engine architecture comes from Ford’s MOD engine family, which includes performance powertrains like the 390-horsepower 4.6-liter DOHC supercharged V-8 in the SVT Mustang Cobra and the 380-horsepower 5.4-liter SOHC supercharged V-8 in the SVT F-150 Lightning.
“We’re just starting to tap the performance potential of Ford’s modular engine architecture,” says Curt Hill, Ford GT powertrain engineering supervisor. “This application really demonstrates its awesome potential. The 5.4-liter engine easily produces 500 horsepower and 500 foot-pounds of torque, while meeting all the current emissions and durability standards. Those numbers are comparable to the race-prepared, blue-printed 427 (7.0-liter) big-blocks in the Ford GT race cars.”
The Ford GT engine features an all-new, aluminum block fitted with high-flow, four-valve cylinder heads and dual overhead camshafts. To bear the stresses necessary to produce 500 horsepower, a forged-steel crankshaft, shot-peened H-beam connecting rods and forged aluminum pistons are used. “In total, 85 percent of the reciprocating parts are unique to the Ford GT,” says Hill.
Fuel is delivered via dual fuel injectors per cylinder. A modified screw-type supercharger blowing through a water-to-air intercooler supplies sufficient airflow for engine output.
Hill’s team specified two race-inspired powertrain components, a dry-sump oil system and a twin-plate clutch. The high-capacity, dry-sump oil system provides consistent lubrication, even during maximum handling. The twin-plate clutch delivers low pedal efforts while still providing the clamp loads necessary to handle 500 foot-pounds of torque.

More significantly, these two features allow the powertrain to sit more than 4 inches lower in the frame as compared with the front-engined SVT Mustang Cobra. This helped maintain the low design profile and keep the car’s center of gravity low for better handling. Backing the clutch is an all-new, six-speed transaxle from Ricardo. The clean-sheet design enabled Ford engineers to tailor the individual ratios to their specifications, without being forced to select from an existing assortment. The transmission is fully synchronized and features an integral, torque-sensing, limited-slip differential.
