A midengine configuration carries an aluminum engine cradle behind the bulkhead that holds the 500-hp V8.

SVT engineers had a hand in the creation of the GT40 concept, unveiled at the 2002 Detroit International Auto Show. Inspired by the GT40 Le Mans racecars of the late 1960s, the concept is part of the Living Legends lineup which includes Thunderbird and Mustang, as well as the Forty-Nine concept.

SVT engineers are responsible for vehicle development, creating the chassis and powertrain for the GT40. They developed an entirely new aluminum spaceframe which provides a rigid cradle for the engine and driveline. The frame consists of a central cabin section, a front-suspension subsection, and a rear powertrain chassis cradle, all bolted together. The front and rear suspension use unequal-length control arms, and a push-rod/bell-crank system which links to horizontally mounted spring dampers.

The modular (MOD) 5.4-liter V8 provides 500 hp at 5,250 rpm and 500 lb-ft of torque at 3,250 rpm. The aluminum powerplant carries high-flow, four-valve cylinder heads and DOHCs. A forged-steel crankshaft, shot-peened H-beam connecting rods, and forged aluminum pistons help withstand the 500-hp load. Also, the V8 uses a modified Roots-type supercharger from Eaton with an intercooled intake.

SVT engineers installed a special transaxle to accommodate the mid-engine layout. A close-ratio six-speed transmission is fully synchronized and features an integral limited-slip differential and a 9-in. heavy-duty clutch.
