The GTR hands down! Then new GTR is equiped with a VR38DETT! With the AWD this car can go 0-60 in 3.2 seconds with launch control an runs 11.5 in the 1/4 mile! Top speed it just over 190 mph! As long as we are talking about a street car race between the viper an GTR then the GTR would win! Same thing for a full race GTR an viper the grr would still win! All the number for the GTR are for a stock one! With a tune more boost an bigger turbos the gtr could easily be a 10 sex car!
