If you can’t decide whether to buy a racer or a street car, Ford offers a solution. This special concept called the TracKey will be introduced on the 2012 Mustang Boss 302.
Drivers will be given two keys – a black one and a red one. With a black key, the driver will get 444 hp with a street engine setup while the red key will unleash the motorsport features in the ‘Stang Boss.
Jeff Seaman, Mustang powertrain engineer, said that from an engine management standpoint, the company has done “everything possible” to provide a full race car experience to TracKey users.
He explained that when it isn’t to be used on the streets, the deceleration is set up to preserve the brakes, and it gets a “very aggressive” throttle response.
TracKey was co-developed by Mustang Engineers and Ford Racing. It is equipped with a second set of powertrain control module (PCM) software, which can be activated by a special key.
When the red key is used, more than 200 parameters of the vehicle's 5.0 liter V8 are modified. Quite literally, the stock vehicle instantly becomes a competition-ready vehicle.
The parameters that are affected include the variable cam timing, spark maps, engine braking, fuel control, as well as a two-stage launch control.
Dave Pericak, Mustang chief engineer, said that “anything that could possibly affect all-out performance” is removed from the TracKey calibration. He said that throttle limiting and torque management and any daily driveability enhancements are deleted and swapped with a pure Ford Racing competition calibration.
