Yeah it looks much better than most Porsche's. 0-60 will be a lot faster with the V10, when it finally goes on sale. But I think offering the R8 with the V8 gives it some identity, there's no point in just making a re-bodied Gallardo.
According to the Audi press release:
"The performance figures are equally impressive: the R8 accelerates from a standstill to 100 km/h in 4.6 seconds and reaches a top speed of 301 km/h."
