I dont think we will see this in Geneva, im guessing probably towards later in the year. Audi is having it;s audience soak with the V10 R8 and Spyder for a while until they release this beast.
What i would love to see in the R8 GT (im definitely way off but this is my wish)
3300lbs
4.5L TwinCharged V8 - 545hp
S-tronic
AWD
