Since 2006, Gemballa has been building custom interpretations of the Porsche Carrera GT supercar, making it perhaps the foremost Carrera GT tuner in the world. For its latest iteration, Gemballa has decided to relax the power output and focus on a simple bi-color design scheme. We first saw this latest Mirage GT ‘Carbon Edition’ back in February and today the famed German tuner has announced it will be taking the car to a new level of exclusivity by only building five examples.

Some of Gemballa's GTs have put out as much as 750hp (560kW), but the Carbon Edition is satisfied with 670hp (500kW) on tap. That's still about 50hp (40kW) more than the stock Carrera GT, however, and with 465lb-ft (630Nm) of torque, it's sure to be a fun ride in any gear.

Gemballa's claimed performance stats back that up: 0-62mph (100km/h) takes 3.7 seconds, and it'll hit 124mph (200km/h) in just 9.7. Both of those figures shave two tenths of a second from the stock times, and the power boost takes top speed up to at least 208mph (335km/h).

Beyond the power mods, the Carbon Edition adds lots of exposed carbon fiber accents, a black-on-white color scheme and custom alloy wheels. A hydraulic height-adjustable coilover kit is also supplied to improve handling, as well as protect the car when any steep bumps need to be conquered.

Pricing for the upgrade starts at €298,000 (approximately $426,000), with the customer required to supply their own Carrera GT.
