We’ve seen Geiger modifying a lot of sport cars like Dodge Viper but they wanted a new challenge and started to modify a Hummer H3 V8 Kompressor. They made a special body kit for this ride with no rear spare tire and they installed a lot of carbon fiber elements in the car’s interior. This Hummer has almost the same weight as the stock car but it’s performances were improved a lot. The stock H3 had an engine with 300 HP and this one by Geiger has a 5.3L V8 engine which could deliver 423 HP. You couldn’t imagine a huge car like this one accelerate in just 7 seconds from 0 to 100 km/h but this H3 could do that.
