Supercar Ford GT500 is mechanically an evolution of the previous model.Ford used the current-gen Bullitt model as the starting point for the 2010 Mustang GT, the lessons learned from developing the limited edition GT500 KR fed directly into the latest Shelby-badged variant. Output of the supercharged 5.4L V8 has now been cranked up to 540 hp and 510 lb-ft of torque, and the handling is claimed to be better than before.
Compare with the old GT500, this new supercar model gets more aggressive styling, particularly in the nose, and reprises many of the same detail elements. The horizontally mirrored trapezoidal shape of the grille in the upper and lower front fascia is meant to echo the oval shape of the Shelby Cobras of the '
60s. The upper grille is tilted forward at a steeper angle than the GT and the grille surround is separated entirely from the hood. The hood of the GT500 still has a functional air extractor allowing some of the massive heat generated by the blown V8 to escape.
The engine for this supercar is still a twin cam 5.4L V8 with a supercharger. The updates bump output from from 500 hp at 6,000 rpm to 540 hp at 6,200 rpm. Twisting fo
rce also goes from 480 lb-ft at 4,500 rpm to 510 lb-ft at the same peak speed. The iron block from the F-150 was used with the top end of the GT engine, which pushed the car's weight up over 3,900 lbs.
The top two ratios in the new GT500's gearbox have been made numerically lower. The clutch plates for supercar GT500 have been increased in diameter from 215 mm to 250 mm. All that torque flows from the Tremec 6-speed gearbox through a limited slip differential with a 3.55:1 final drive ratio. The 2010 GT500 gets 17% stiffer springs at the front axle and 7% stiffer at the rear axle.
