The Porsche 911 is a car that tuners will never get tired of modifying, and TechArt is one of the bigger names in Porsche tuning. The problem with tuning a car like the 911 Turbo S is that Porsche has already done an amazing job of squeezing huge amounts of power out of the 3.8-liter flat six engine nestled in the tail end of the iconic sports car. This did not deter TechArt though, and their tuned Turbo S is putting out 620 horsepower.
This is all thanks to some improved breathing parts on both the intake and exhaust sides, as well as an all-important ECU remapping. Thankfully, TechArt has stuck to making the car faster, and you'd have to open the hood in order to know it's been modified. This would almost make the car a sleeper, if it wasn't also a 911 Turbo S.
