Porsche 996 GT3 Cup
Its water-cooled naturally aspirated engine had dry sump lubrication with a separate oil tank. The engine output of initially 265 kW (360 hp) was 272 kW (370 hp) from 1999. Super Plus was used as fuel . The engine enabled an acceleration from 0 to 100 km / h in less than four seconds and a top speed of 286 km / h. The adjustable rear wing produced up to 1000 Newtons of downforce.
The 996 GT3 Cup was modified for the 2001 season. The large rear wing doubled the downforce on the rear axle and thus ensured better road holding and less tire wear. The engine, transmission and brakes received improved cooling thanks to a new front section. 113 vehicles of this version were produced.
In 2002 the 996 GT3 Cup was improved again and received the teardrop-shaped headlights of the turbo versions. The new front section improved the flow of cooling air by 15 percent. A new rear wing that can be adjusted in seven stages reduced lift, which enabled higher cornering speeds. The weight of the vehicle remained constant thanks to the lightening of the doors, windscreen and exterior mirrors. The engine control of the 996 GT3 RS was now also used in the 996 GT3 Cupused, whereby a power increase of ten to 279 kW (380 PS) and a higher maximum torque of 380 Newton meters was achieved. Another major change involved the brakes. On the front axle, the diameter of the brake discs increased to 350 mm, while on the rear axle it remained unchanged at 330 mm. Together with six-piston fixed calipers on the front brake discs and improved ventilation of the front wheel arches, the braking power could be increased. For use in long-distance races, the transmission was spray-cooled with an oil-water heat exchanger.
In 2004 the 996 GT3 Cup underwent its last revision, which mainly affected the vehicle weight, which could be kept at 1150 kg. The rear cover, engine compartment lid and doors were made of carbon fiber reinforced plastic (CFRP) and all windows with the exception of the front window were made of plastic. The engine output increased to 287 kW (390 hp) at 7200 rpm and the maximum torque was now 390 Nm at 6500 rpm. There the long straights of the Hockenheimringwere no longer in the program, the courses were translated four to six shorter. The infinitely adjustable chassis made fine tuning possible. For use in long-distance sports, the tank volume has been increased from 64 to 89 liters. The interior ventilation has also been improved. For safety, the roll cage was padded and the HANS system could now be used.

Porsche 997 GT3 Cup/Cup S/R
The cup version of the Porsche 997 GT3 made its debut in the Porsche Supercup in 2005 and has also been used in the Porsche Carrera Cup since 2006.
The total downforce increased by around 40 percent compared to the previous model, which was achieved through a new front section with an adjustable spoiler and a 60 mm wider and 35 mm higher rear wing. Due to the increased use of parts made of CFRP, the vehicle weight remained at 1150 kg. In addition, the air flow and removal of the cooler and brakes have been improved. The engine developed 294 kW (400 hp) at 7300 rpm and delivered a maximum torque of 400 Newton meters at 6500 rpm. The maximum speed was 8200 rpm. In addition, a sequential six-speed transmission with interruption of tractive power has now been installed. The wheel carriers were taken over from the more powerful 911 RSR . Ceramic brake discs too were now used, but no anti-lock braking system, as it is not allowed in GT racing series, where the 911 GT3 Cup is now increasingly used.
In 2008 the 997 GT3 Cup was revised. The engine output was increased to 309 kW (420 hp) and the maximum torque to 420 Nm. Of this vehicle, 265 were to be built in the first year and 215 in the following year. 
In 2010 the cup model was revised. It was now based on the 2009 GT3 RS and, in addition to its modified body shape, also received the 3.8-liter engine of the street model. The engine output of the new Cup Porsche therefore increased to 331 kW (450 PS). In addition to the Supercup, Porsche planned to equip the Carrera Cups in Germany, Asia, Japan and Italy with the new vehicle in 2010. The cars will also be used in the GT3 Cup Challenges in the USA and the Middle East.
Porsche 997 GT3 Cup S
The 997 GT3 Cup S appeared in 2008 as the new racing version of the 911 GT3 . The vehicle is based on the 997 GT3 RS road sports car and is based on the GT3 group regulations . So the car can be used in international championships. The engine output has been increased by an improved engine management system and a modified exhaust system by 15 to 324 kW (440 hp) at 8000 rpm. The maximum torque of 430 Nm is available at 7250 rpm. Compared to the 997 GT3 Cup, the vehicle has larger and wider wheels. The contact pressure is greater due to an adjustable front splitter and a wider and higher rear wing. The chassis is largely identical to that of the more powerful 997 GT3 RSRidentical. The diameter of the 355 mm brake discs on the rear axle is five millimeters larger than on the 997 GT3 Cup. 
Porsche 997 GT3 R
In addition to the further development of the Cup vehicle for the 2010 season, the successor to the Cup S was presented in January of that year. This expansion stage, called the 997 GT3 R, is, in contrast to the 996 GT3 R, not a vehicle of the GT2 group , but, like the Cup S, complies with the GT3 regulations.
Porsche 997 GT3 R Hybrid
Porsche developed a hybrid drive with flywheel storage for the 997 GT3 R, which was presented at the Geneva Motor Show. According to Porsche, it will soon be available in conjunction with other models. Since there is no battery, the energy is stored in a flywheel instead of the battery, which rotates at up to 40,000 revolutions per minute. Its memory is charged during braking. For this purpose, two electric motors with 60 kW each work as generators when braking, the electricity drives the flywheel via another electric motor. When you accelerate, the energy flows in the other direction: the motor on the flywheel acts as a generator, brakes it and thus generates enough electricity to provide six to eight seconds of additional electrical thrust for the vehicle.
On March 27, 2010, the Porsche 997 GT3 R Hybrid made its racing debut at the VLN Endurance Championship Nürburgring .  At the 24-hour race at the Nürburgring , the team retired after 22 hours of being in the lead with a technical defect. The oil pump for dry sump lubrication failed, resulting in engine damage.

Porsche 991 GT3 Cup
On December 8, 2012, the new 911 GT3 Cup based on the Porsche 991 was presented as part of the Night of Champions in the Porsche Development Center in Weissach.
The new edition of the 911 GT3 Cup is the motorsport version of the future 911 GT3 and thus the first racing car based on the seventh generation of the 911. The new 911 GT3 Cup will be used exclusively in the Porsche Mobil 1 Supercup in 2013 . The new one-make cup car had its world premiere as part of the motorsport end-of-season celebration "Night of Champions" in the Weissach development center. The new Porsche 911 GT3 Cup is powered by a 3.8 liter six-cylinder boxer engine. It develops 460 hp (338 kW) at 7,500 revolutions, which is ten hp more than the engine of the previous generation. The power is transmitted by a six-speed claw transmission developed by Porsche Motorsporton the rear axle. It is operated for the first time in a one-make cup vehicle from Porsche using paddle switches on the steering wheel. The one-piece racing bikes with central locking and a diameter of 18 inches were also redesigned by Porsche Motorsport. The width of the Michelin racing slicksgrew by two to 27 centimeters on the front axle and by one to 31 centimeters on the rear axle. A newly developed racing brake system ensures even better long-distance suitability compared to its successful predecessor. The 38-centimeter, slotted and internally ventilated brake discs are retarded on the front axle by six-piston aluminum monobloc racing brake calipers, while the brake calipers on the rear axle have four pistons. When developing the new vehicle, particular attention was paid to the safety of the pilots. In the event of rollovers and collisions, a newly calculated roll cage provides protection, as does a new type of racing bucket seat with a particularly strong shape in the head and shoulder area, which can be perfectly adapted to the shape of the body with special pads. A rescue hatch in the roof makes it easier for route safety to provide first aid and rescue drivers who have had an accident. “The new 911 GT3 Cup is much easier to drive at the limit,” says the Porsche works driverTimo Bernhard , who played a key role in the development of the new vehicle. “The car is extremely well balanced. The new axle geometry has an extremely positive effect on driving behavior. On top of that, the new Cup 911 is a lot of fun. ”Like its predecessor, the new Porsche 911 GT3 Cup is built on the same production line in Stuttgart-Zuffenhausen as the road models. At the Weissach Motorsport Center, it receives a basic set-up for the racetrack and is tested by a professional racing driver before it is delivered to the customer. The basic price of the vehicle, which is only available in white, is 181,200 euros plus country-specific sales tax.
Racing outside of the brand cups
Due to their high competitiveness at a comparatively low price, Porsche 911 GT3 Cups, which were formerly used in the Carrera Cup and Supercup, are widely used in national GT racing series and in popular sport.
Traditionally, a lot of teams start in a Porsche 911 GT3 Cup in the VLN endurance championship Nürburgring and the 24-hour race at the Nürburgring . The number of participating vehicles of this type is regularly in double digits.
The Spa-Francorchamps 24-hour race has also been a guest starter in a Porsche 911 GT3 Cup in recent years. The Porsche 911 GT3 Cup has also been in action there since races in which GT3 regulations are used, such as the FIA GT3 European Championship and the ADAC GT Masters . With the Porsche 911 GT3 Cup S, there has been a vehicle specially designed for long-distance races based on GT3 regulations since 2008.
In 2010 the American Jeff Zwart set a new record in the Time Attack 2WD category at the Pikes Peak International Hill Climb in a Porsche 997 GT3 Cup with 11: 31.095 minutes .  In 2014 he drove again with this chassis, but this time (for reasons of the enormous power loss at great heights) instead of the original Cup engine with a variant of the turbocharged 997 GT2 engine.
