While the pictures above show a regular Audi R8, the four-ring brand is working on a new supercar, codenamed the NF, that uses a vast amount of carbon fiber in the vehicles construction to help shed serious weight.
Audi previewed the vehicle at a private event in Germany, but security was extremely tight, and only a rendering of the passenger compartment was shown. Furthermore, cameras were explicitly banned. Audi did have on hand a prototype R8 with a carbon fiber roof and floor pan, as well as a crash tested model that was made of a similar construction, but only photos of the intact prototype have surfaced.
The NF is expected to bow in 2014 as part of an on-going program within Audi to expand the use of lightweight materials across their lineup. The R8 Spyder already uses a carbon fiber engine cover, while the E-Tron will introduce features like a carbon fiber roof. At that point, the NF, if it exists, will then debut with substantial structural elements made of the lightweight material.
