Here in the U.S., auto shows are pretty much done for 2012, but Europe is still enjoying the Essen Motor Show and the amazing tuning cars displayed in there. One of these amazing cars – “amazing is likely an understatement – is the GT9 Vmax developed by 9ff.

The new Vmax package continues from where the GT9-R package left and has significantly improved both power and performance. The GT9-R delivered a total of 1,120 horsepower and was capable of peaking out at 414 km/h (257.2 mph), but the Vmax would simply walk away from its predecessor.

The Vmax is powered by a 4.2-liter, twin-turbocharged flat-six engine that delivers a total of 1,381 gut-checking ponies and 855 pound-feet of twist. The extra power helps it rocket to 100 km/h (62.1 mph) in just 3.1 seconds. If that’s not enough for you, the Vmax also launches to 200 km/h (124.3 mph) in 6.8 seconds and to 300 km/h (186.4 mph) in 13 seconds. If you though the GT9-R’s top speed was nuts, you’re in for a serious treat, as the Vmax touts a 437 km/h (271.54 mph) top speed.

The tuner also added in plenty of carbon-fiber body work, polycarbonate windows and a set of lightweight wheels. As expected, with great performance comes a grand price tag. The 9ff GT9 Vmax comes in at €895,000 - or about $1,170,000 at the current exchange rates.
