The 993 GT2 was built to meet homologation requirements for GT2 class racing; the road cars were badged as the 911 GT. It featured widened plastic fenders and a larger rear wing with air scoops for improved engine cooling. Its 3.6 L engine produced 316 kW (430 PS; 424 hp), upgraded in 1998 to 331 kW (450 PS; 444 hp). Fifty-seven road cars were built, thirteen of which were right-hand drive.
In 1999, the 993 was replaced by the 996 model. Porsche abandoned the GT2 for motorsport with this generation, concentrating instead on Le Mans GT class racing with the naturally aspirated 911 GT3. The 996 GT2 was developed primarily as a road car and used a twin-turbocharged version of the GT3's 3.6 L flat-six engine, producing 340 kW (462 PS; 456 hp), later raised to 355 kW (483 PS; 476 hp). Its body differed substantially from other 996 variants, with wider fenders, a more aggressively shaped nose, and a large rear wing. Despite a 10-millimetre reduction in ride height versus the 911 Turbo, its drag coefficient of Cd=0.34 was slightly higher than the Turbo's Cd=0.33 due to the fixed rear wing.
The 997 GT2 arrived at dealerships in November 2007 following its launch at the 62nd Frankfurt Motor Show. Its 3.6 L flat-six engine used two variable geometry turbochargers, producing 390 kW (530 PS; 523 hp) at 6,500 rpm and 680 N⋅m (502 lb⋅ft) of torque. It accelerated from 0 to 100 km/h in 3.6 seconds, reached 200 km/h in 10.6 seconds, and had a top speed of 328 km/h (204 mph). Motor Trend recorded a 0–60 mph time of 3.4 seconds and a quarter-mile time of 11.4 seconds at 127.9 mph. Porsche test driver Walter Röhrl lapped the Nürburgring Nordschleife in 7 minutes 32 seconds on a public day.
The 997 GT2 RS was announced in May 2010. Its engine produced 456 kW (620 PS; 612 hp) and 700 N⋅m (516 lb⋅ft) of torque. Weighing 70 kg less than the standard GT2, it reached a top speed of 330 km/h (205 mph) and a 0–97 km/h time of 3.3 seconds. Only 500 units were produced globally. The RS project was conceived around 2007 as a skunk-works effort; the internal 727 code number corresponded to the Nissan GT-R's Nordschleife lap time, which test driver Timo Kluck reportedly beat by nine seconds.
The 991 GT2 RS was unveiled at the Xbox E3 2017 briefing alongside the announcement of Forza Motorsport 7. It was officially launched at the 2017 Goodwood Festival of Speed. It is powered by a 3.8 L twin-turbocharged flat-six producing 515 kW (700 PS; 691 hp) at 7,000 rpm and 750 N⋅m (553 lb⋅ft) of torque — the most powerful production 911 variant ever built. Unlike earlier GT2 versions, it uses a 7-speed PDK transmission. Porsche claims a 0–97 km/h time of 2.7 seconds and a top speed of 340 km/h (211 mph). Wet weight is 1,470 kg (3,241 lb).
The car's structure uses a magnesium roof, carbon-fibre front lid, front and rear wings, and boot lid; lightweight polyurethane front and rear aprons; polycarbonate rear and side windows; and a titanium exhaust system. An optional Weissach package reduces weight by a further 30 kg (66 lb) through additional carbon-fibre and titanium parts, including carbon-fibre anti-roll bars, coupling rods, and a titanium roll cage, plus magnesium wheels made by BBS. A production run of 1,000 units was planned; four were lost when the ship Grande America sank in transit to Brazil in March 2019, and Porsche restarted production to replace them.
In September 2017, Lars Kern set a 6:47.3 lap of the Nürburgring Nordschleife in the standard 991 GT2 RS, then the fastest production car lap recorded there. In October 2018, a 991 GT2 RS MR prepared by Manthey Racing — with Porsche owning Manthey — set a 6:40.33 lap on the same circuit. In 2018, Warren Luff set the fastest production lap record at The Bend Motorsport Park (3:24.079 min around the 7.77 km GT layout) without the Weissach package. In 2019, Porsche set production lap records at Road Atlanta (1:24.88 min), Road America (2:15.17 min), and Canadian Tire Motorsport Park (1:22.36 min).
Introduced at the 2018 LA Auto Show, the GT2 RS Clubsport is the track-only variant. New aerodynamic elements increase downforce; removal of non-essential components reduces weight further to 1,390 kg (3,064 lb), 80 kg less than the road car. It features a larger motorsport-oriented carbon-fibre rear wing shared with the GT3 R, larger front air intakes with integrated LED daytime running lights, a carbon-fibre roof with an escape hatch, and a racing fuel cell. The interior includes an FIA-approved roll cage, a single racing bucket seat, and a carbon-fibre race steering wheel with an integrated colour display, both shared with the GT3 R. It runs 18-inch centre-lock forged wheels wrapped in Michelin racing slicks, also shared with the GT3 R. Engine and transmission are carried over from the road GT2 RS. Production is limited to 200 units. The Clubsport made its track debut at the Bathurst 12 Hour in January 2019 and featured in an SRO Motorsports Group one-make series at the 24 Hours of Spa Weekend in July 2019.
The 993 GT2 race car was fielded in the BPR Global GT Series and smaller national series. During its first full BPR season in 1996, it earned seven class wins out of eleven rounds, plus class victories at the 24 Hours of Le Mans in 1996 and 1997. In the FIA GT Championship, the GT2s won three races despite factory-backed competition from Chrysler. By 1998, the Chrysler Viper GTS-R became dominant and the GT2 could earn only a single victory. In 1999, a GT2 prepared by Roock Racing won the GT2 class at the 24 Hours of Daytona. Porsche ended support for the GT2 project in 2000 and shifted focus to the N-GT category with the GT3-R.
The GT2 traces a long lineage through Porsche Turbo-based racing cars, from the 1974 911 Carrera Turbo for Group 5 racing, through the 934 (a racing version of the 930), the 935 (dominant in Group 5 and IMSA racing through 1984), and the 961 (a racing version of the 959). A GT2 Evo variant was developed capable of competing in the GT1 category with 447.6 kW (600 hp), but was replaced by the purpose-built 911 GT1 in 1996. With the 991 generation, Porsche committed to the new SRO GT2 category with the GT2 RS Clubsport, competing in GT Sports Club America from 2020 and the GT2 European Series from 2021. An Evo kit for the Clubsport was introduced in 2023.
