Porsche 991.1 GT3 Cup Car
The Porsche 991.1 GT3 Cup is powered by a 3.8-litre, six-cylinder flat engine, delivering 460 hp (338 kW) at 7,500 rpm, an increase of 10 hp over its predecessor. Power is transferred to the rear axle via a six-speed dog-type gearbox, developed by Porsche Motorsport, which is operated for the first time (when released) in a Porsche brand Race Car using shift paddles on the steering wheel.
Driver safety was a key focus in the car’s development. A newly designed safety cage ensures protection in the event of a roll or collision, while the race seat is tailored to provide additional support around the head and shoulders. Read on to learn more and view our Porsche Cup Cars for sale.
