Reworking a Carrera GT is one of those things that likely takes longer than you think. It's hard to tinker with a Porsche like this and expect to improve it easily.

So it's forgivable for Gemballa to be as of yet not finished with its Mirage GT Carbon Edition. But it had better be as impressive once they are. Hey, that's the game of expectations one engages in within the world of tuning super cars.

What we do know is very little. The claim is that the Mirage GT Carbon Edition will have 670 hp and be able to full sprint at 335 km/h (208 mph). 0 to 100 km/h (62 mph) is said to be reached in 3.7 seconds and 0 to 200 km/h comes in at 9.7, shaving 0.2 off the clock from the standard Carrera GT in both.

The name 'Carbon Edition' can only mean that Gemballa has put the Carrera GT on a serious diet through extensive use of carbon fiber parts and ceramic brakes. Although, that mere 0.2 seconds improvement in acceleration doesn't necessarily jive with an exceptionally high weight reduction.

Still, so far these photos make the Mirage GT look good. It's smooth and sleek and you're already most of the way there when you like the way a car looks, aren't you? Who ever wants a car they think is ugly?

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.

Some of Gemballa's GTs have put out as much as 750hp (560kW), but the Matt 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.

Inside, there’s a mix of blue Alcantara and leather trim as well as carbon-fiber and aluminum accents.
