The Corvette ZR1 is considered one of the most impressive sports cars in the United States, and the German tuners from Geiger Cars has taken it under their wing. Debatably one of the best performing sports cars today, the stock Corvette ZR1 features the LS9 6.2-liter small block engine that produces 647 hp and 823 Nm of torque. Geiger was able to distribute the weight better for improved handling by installing an electronically controlled sport suspension. They also added a high performance brake system with carbon ceramic brake discs measuring 394 and 381 mm. Geiger Cars decided the performance numbers were not enough, so they improved them with some simple engine tuning, and named it the GTS Corvette ZR1. With the modifications to the engine, Geiger was able to pump out 710 hp at 6,600 rpm and 918 Nm of torque at only 4,200 rpm with the Corvette ZR1.
