The Gemballa Avalanche Roadster GTR600 is based on the Porsche 911 Turbo Convertible. If a standard Porsche 997 has a maximum power of 480 hp, the GTR600 develops 600 hp and a peak torque of 840 Nm.
This performance will help it make the 0 to 60 mph sprint in just 3.5 seconds and hit a top speed of 320 km/h.
As Gemballa says the interior is made for "spoiled people". It features F1 aluminum pedals and high tech materials like carbon fiber and aluminum.
