Apollo r (Germany, 2012)

The Apollo R is a non-street-legal car that represents the ultimate Apollo track car.

Power is boosted to 860hp from its supercharged 4.2 liter V8, and extensive modifications were necessary. The supercharger pressure was increased to get the extra power. It also has optimized air intakes and a race exhaust. Because many Gumpert buyers are in Asia, the engine and transmission cooling were beefed up to work in hot, humid climates. The car uses an electronically-controlled, semi-manual transmission operated via paddle shifters behind the steering wheel. Racing fuel must be used in the Apollo R.

The upgrades lead to further strengthening of the chassis. The rear stabilizer bar is made from titanium. Numerous changes including a simplified wiring harness, milled parts and lightened body parts dropped the dry weight down to 1,100kg.

To imagine these cars' performance keep in mind that a Veyron has 1,000hp but weighs about 700kg more than the Apollo...
