While the factory Mustang GT gets over 330hp from its 4.6L engine, Grassl decided this wasn't enough and increased output by 35hp, bringing a total of 365hp. While the five-speed manual transmission remains stock, the chassis was altered to provide a stiffer and sportier ride.
The German tuner, noted mostly for modifying BMWs, also put some non-mechanical mods on his Mustang. The list includes polished 20in wheels and a subtle bodykit. In a salute to clean lines and impeccable form, Grassl removed the unsightly telescopic antenna from the left front fender and attacked the interior with red leather to give the car a retro look.
Inside, there’s also a Rainbow Platinum stereo system with a Kenwood DNX 7200 head unit and a 12in subwoofer. The final touch is a pair of LCD panels located inside each door, however actually watching these while inside the car is near impossible.
