It has certainly been no secret that Audi is planning a lightweight, rear wheel drive R8 that would go head to head with the Porsche GT3. The only question has been: HOW SOON?
Audi seems a little too obsessed with spreading out these "NOT VERY NEW TECHNOLOGY," design upgrades, over as many years as possible in order to completely "utilize" its original R8 customer base. So I guess Audi's lightweight, GT3 R8 model will finally arrive as soon as the new R8 GT market has been fully addressed.
Maybe the Audi GT3 type R8 will happen using the current R8 design, or maybe it will be as an ultra expensive, completely new R8 re-design model. And from this most expensive new re-model, they will slowly, over a few years, offer to us some cheaper, tuned down models in a similar manner that Porsche seems to be introducing its new 918 flagship platform. Start with an ultra new top model and then work down?
The heavy weight of the current R8 chassis and its lack of a modern, dual clutch transmission have long been the car's only significant weaknesses. Carbon fiber body parts represent NO new technology, nor do PDK type trannys. The only NEW technological advance I would truly cherish from Audi would be their development of quality CF monocoque chassis construction costs equaling the same, or costing less than the current very heavy, metal frame sportscar construction. Now that is something that I would salute!
Tuners have been making R8's using carbon fibre body panels for years with over 550 LBS of weight lost, plus another 50-60 LBS reduction for RWD! This is very significant weight loss! It's nothing new. I think its about time that Audi decided to do the same.
