The most prolific racecar on the circuit, the Porsche
911 has been soldiering on in competition spec based on the previous generation. But now Porsche has released the new 991-gen GT3 Cup. While the previous model produced 450 horsepower, the 3.8-liter flat six in the new Cup has been tuned to 460 hp, driving the rear wheels through a six-speed sequential gearbox. But there's more to the new race-spec 911 than its engine. A high-flow exhaust, adjustable anti-roll bars, 18" alloys with Michelin slicks and 15" brakes get the 911 ready for the track.
