With modern tyres and modern aerodynamics the R8 would loose the 917

In rallying the current cars with about 300bhp are alot quicker then the group B monsters with about 600bhp

In all racing modern cars are quicker overalll due to huge gains in cornering speeds in straght line they might not be as quick but overall no contest
