About the Audi R8 LMS GT2
Audi Sport has rolled out with the R8 LMS GT2 that the company points out is the most powerful car that has been offered in the 11-year existence of the Audi Sport customer racing program: 670 hp, or 123 hp/liter of displacement from the 640-hp, 5.2-liter naturally aspirated V10 engine.
What is equally impressive is the weight to power ratio: The R8 LMS GT2 has a dry weight of 2,970 pounds; the power to weight ratio is 4.62 pounds per horsepower.
Materials play a big role. Like the production version of the R8, the race car, which will compete in the new racing category that will be launched next year, it uses the Audi Space frame, which is fabricated with aluminum and carbon-fiber reinforced plastic (CFRP).
There is a steel roll cage, which has a tubular structure; compared with the Audi R8 GT4 model, the tubes have a reduced wall thickness thanks to the use of a high-grade steel.
The body parts are produced with CFRP. The doors are a combination of CFRP and an aluminum honeycomb material that is required for safety regulations.
The windshield and the side windows are made with Makrolon, a polycarbonate from Covestro.
According to Audi, it “is the ideal sports car for classic fielding in races, as well as being suitable for Track Days and events at Race Resorts.”
