During a recent technology demonstration, Audi engineers teased the fact that they are developing a lightweight R8 codenamed the NF.

Over the years, Lamborghini has learned that lightweight models like the Gallardo LP570-4 Superleggera can add significantly to the bottom line. Now it appears that lesson has found its way to the halls of Ingolstadt, Germany.

During a recent technology demonstration at the company's lightweight research and production facility, engineers teased the fact that they are developing a lightweight R8 codenamed the NF. Details are limited, but several prototypes were displayed with a carbon-fiber rear bulkhead and a complete carbon-fiber body (including the roof and floor pan). All told, the changes are estimated to reduce the car's weight by approximately 20 percent which is rather astounding considering the R8 5.2 would lose 743 lbs (337 kg).

While there's always the chance that Audi is just experimenting with advanced carbon fiber construction techniques, the company showed a timeline that indicated the NF was due to be launched in 2014. Furthermore, Audi is conducting crash tests of the prototypes which seems to indicate that the NF is likely headed for a dealer near you.
