We all know the GT3 RS is a track car made for occasional use on the street, but how does it compare to the 911 Turbo S, the horsepower king of the 911 line-up. The GT3 RS has 500 hp, it's normally aspirated with rear wheel drive and weights around 1405 kg. Perhaps, most importantly, it has a wider front track than the Turbo S and is fitted with super sticky Sport Cup 2 tires. The Turbo S, on the other hand, has 60 more horsepower, significantly more torque, big turbos and 4-wheel drives. However, it weighs a few hundred pounds more and wears "normal" P-Zero tires. How do the two compare to each other on the track? That's exactly what evo's Jethor Bovingdon aims to find out in the video below? The results might surprise you.
