Porsche 911 GT3 Cup: the World's Top-Selling Racing Car

The 911 GT3 Cup is the world's top-selling racing car. First presented in 1990, the car is now in its seventh generation and has sold over 4,500 units worldwide.

One of the most striking features of the new 911 GT3 Cup is its optimised aerodynamics and the overall more muscular appearance. This is partly thanks to the wide turbo-spec lightweight body that is being used for the first time in the Cup car. Measuring a total of 6.25 feet in width, it exceeds the rear width of the previous model by one inch and is distinguished by its additional cooling air inlets in front of the wheels.

At the same time, the seventh generation of the Cup racer generates noticeably more aerodynamic downforce. This is thanks to the combination of the rear spoiler with the larger rear wing and front apron. The eleven-stage adjustable rear wing with a ‘swan neck’ mounting ensures uninterrupted under-wing airflow. This improved aerodynamic efficiency also ensures more stable handling, especially in fast corners.

Greater Control at Your Fingertips

The so-called Rubber Switch Panel (RSP) with its ten large buttons on the right is reminiscent of a control element in the Porsche 919 Hybrid. These buttons are easy to use, even in the heat of the race, and are given designated central functions such as lighting and ventilation or to change tire settings from dry to wet tires. One example of a clever enhancement to details is the adjustment of brake balance: Now, it can be intuitively controlled via a rotary knob switch on the outside right of the RSP in or against the direction of travel – depending on whether the front axle needs more or less brake pressure.

The designers have revamped the centrally-positioned, 10.3-inch color monitor. The screen prioritizes the display of key data and information for the driver while racing. Displayed alongside the engine revs are water and oil temperatures, the gear currently engaged, and error messages or information on important baseline settings, such as “wet” for racing in the rain.


In terms of the engine, the 911 GT3 Cup remains true to the naturally aspirated principle. In the racing version, the four-liter, water-cooled flat-six engine develops 375 kW (510 hp). Its high-revving unit with dry-sump lubrication reaches top performance at 8,400 rpm – up from the previous 7,500 rpm. It redlines at 8,750 rpm with a maximum torque of 346 lb.-ft. at 6,150 rpm.

Other Improvements

  • Every Cup car from Porsche Motorsport is now delivered with a complete accessory kit, which includes, for example, all special tools and wishbone spacers required for track adjustment. Hence, the ex-works 911 GT3 Cup is ready to race without customer teams having to order these parts individually.

  • In the new model generation, the water radiators remain directly behind the front apron. This positioning was deliberately retained: the risk of damaging the radiators prevents an overly aggressive driving style. At the same time, the placing of a strut ensures that minor nudges go unpunished.

  • Special brake callipers now enable the brake pads to be changed faster. The drive shafts of the rear axle now have a special, more durable motor racing design.

  • Textile loops have been reintroduced as attachment points for tow ropes. These replace the previously used steel swivel tow hooks.

  • A new central nozzle for the fire extinguishing system improves the distribution of the extinguishing agent inside the cockpit.

  • The new positioning of the release unit makes it easier for scrutineers to check from the outside whether the fire extinguisher is working correctly.

  • Adapted safety quick releases for the inside door openers improve the ergonomics when exiting the cockpit as well as safety in the event of an emergency.

  • The onboard electrical system functions without actual plug fuses. This reduces the amount of materials used in the wiring harness and saves weight. The redesign is easier to access thanks to its central positioning.

  • Should the engine stall at the start of the race, the hazard warning lights switch on automatically to warn other competitors of the danger.
