German tuner GeigerCars is exhibiting this Corvette ZR1-based Geiger GTS at the 2009 IAA. Maximum power from the 6.2-litre LS9 is 710hp and top speed is 342km/h.

GeigerCars is based in Munich but American cars are its focus and have been for many years. At Frankfurt the tuner presents its latest high performance car in the form of the Geiger GTS. This supercar is based on the Corvette ZR1, one of the most coveted and respected sports cars of the past couple of years and a recognised slayer of the Nürburgring. Some of its well-documented handling credit must go to the electronically controlled suspension system dubbed Magnetic Selective Ride Control.

Describing the ZR1's engine as "primitive" Geiger set about to extract more out of the factory 6.2-litre LS9. Power has gone up to 522kW (710hp) at 6,600rpm and torque reaches a maximum of 918Nm at 4,200rpm. The 0 - 100km/h sprint takes a mere 3.6 seconds and top speed is 342km/h.

The list of mods includes a wide air vent on the nose, LED foglights, a massive rear diffuser and LED rear lights. The body paintwork is a pearl varnish that appears to change when looked at from different angles and lights.

Wheels measuring 285/30ZR19 at the front and 345/25ZR20 at the back are mated with 10x19 and 12x20 inch high-performance tyres respectively.
