The R8 GT is built with the revolutionary Audi Space Frame [ASF®] chassis, a technology Audi has mastered over more than a decade of experience. The framework of an ASF body consists of extruded aluminum sections and pressure castings. The aluminum chassis and sheet metal are just as strong as steel, but lighter to boost performance and efficiency. The frame carries the sheet aluminum elements, such as the roof panel, which helps withstand loads on the body. The elements of ASF are varied in shape and cross-section, depending on the tasks they have to perform. Like the bones of a human skeleton, they combine optimal function with low weight. The result of ASF technology is a frame that is lightweight yet extremely strong, which delivers high torsional rigidity and optimal performance.
Audi engineers have reduced the weight of the Audi R8 GT compared to the R8 5.2. In addition power has been increased, making for more responsive handling and brisk acceleration.
The following components make the car lighter:
o Lightweight rear hatch made of carbon fiber reinforced plastic.
o Rear diffuser and bumper made of carbon fiber reinforced plastic.
o Rear wing made of carbon fiber reinforced plastic.
o Weight optimized side blades made of carbon fiber reinforced plastic.
o Weight optimized engine cover
o New air intake system
o Lighter carpet and battery
o Reduced engine compartment insulation
The R8 GT boasts a braking system designed to match its impressive power output. The system features a 14.4” front rotor with eight pistons and a 14” rear rotor with four pistons, all of which offers high clamp force for fast, powerful braking. The brakes are internally vented and cross-drilled to increase airflow and cooling, which prevents brake fade for faster stopping.
Optional carbon fiber-reinforced ceramic brakes have specially developed cooling ducts, which offer internal ventilation while providing excellent braking performance and fading stability. The aluminum brake calipers – with six pistons up front -are anodized red and are emblazoned with “Audi ceramic” in a color scheme exclusive to the R8 GT.
As a true supercar the R8 GT not only offers blistering speed but awe-inspiring handling. Featuring the legendary Audi quattro® all-wheel drive system, the R8 GT inspires driver confidence, offering supreme traction regardless of road conditions. To accommodate the extreme performance of the R8 GT, Audi quattro® utilizes a continuously variable torque distribution, dynamically adjusting power to the wheels with the best traction. With a significant 85% rear torque bias and up to 30% available for the front wheels as needed, this highly specialized Audi quattro® system provides the R8 GT with a balanced driving experience unlike any car on the road.
