BMW

Though the BMW M3 Coupe is already a very powerful and capable car, the folks over at Hartge think it can do better, so they came up with this tuning program for the high performance German coupe. The body kit features custom boot lip spoiler, carbon fiber accents and custom Hartge emblems, plus 20 inch Hartge wheels, while on the interior we can find a custom Hartge three-spoke leather steering wheel with carbon inserts, aluminum pedals, aluminum shift knob, leather and aluminum handbrake handle and custom mats complete the interior.

Still, the coolest part of this tuning program is what’s under the hood, Hartge offering two different ECU modifications. The first one offers a raised speed limit of 180 mph (291 km/h), while the other one has no electronically limited top speed. Sky’s the limit! However, for the cars fitted with the second ECU unit, Hartge offers a set of Pirelli P ZERO tires which feature a maximum rated speed of 210.8 mph (340 km/h).
