5000 Cars Up For Porsche’s 911 GT3 Cup: 1990-2023

With the 5000th car rolling off the production line at Stuttgart-Zuffenhausen in November, the Porsche 911 GT3 Cup has become a staple of world motorsport, not only in the astounding variety of one-make championships that feature the cars, but increasingly also in endurance racing where the cars, with mild upgrades, are capable of duking it out with many cars designed from the outset as endurance racers.

That 500th car will do service as the ‘VIP’ car in Porsche Supercup this season with an unmistakable gold and black livery.

It has been 33 years since the first iteration of the Porsche 911 spawned a ‘Carrera Cup’ version – since then Porsche Motorsport have updated and upgraded their one-make racer year by year, transitioning to the next Porsche 911 platform over more then three decades to get to where we sit today – with the current (2021) 911 GT3 Cup, the first competition car that Porsche chose to base on their current 992 platform.

So let’s take an amble back – 33 years, to its great, great, great grandmother – and see how things have progressed!

1990 Porsche Carrera 2 Cup

Base model: Porsche 911 Carrera RS
Debut: 1990 (Porsche Carrera Cup Deutschland)
Displacement: 3.6 litres
Power output: 195 kW (265 PS) to 202 kW (275 PS)
Units built: 297

The 1990 Porsche Carrera Cup was based on the 964 platform, and had, by modern standards, very little done to convert the car for competition.

The car was created for the then new Porsche Carrera Cup Germany, a successor series to the Porsche 944 Turbo Cup that ran from 1986-89.

Just 50 examples were built of the car for the inaugural 1990 season. Whilst the car saw only a 15 bhp increase in output over the standard 964 Carrera RS road car (up to a heady 260 bhp), the parallel weight reduction process was more extreme, some 250 kg taken out of the car despite fitment of a roll cage. The mechanical and electronic upgrades included a blueprinted engine, competition ECU, lightened flywheel and racing clutch.

With mild upgrades the 964-based car saw service through to 1993 with the German Series joined by a new French Series and, in 1993, the first Formula One-supporting Porsche Supercup. By this point the production total for the ‘Cup’ had reached over 170 cars.

1994 Porsche 911 Cup (993) 3.8

Base model: Porsche 911 Carrera RS
Debut: 1994 (Porsche Carrera Cup Deutschland)
Displacement: 3.8 litres
Power output: 228 kW (310 PS) to 232 kW (315 PS)
Units built: 186

1994 saw the debut of the Porsche 911 Cup 3.8, based around the then-current 993 platform, the last of the air-cooled 911s. The cars saw service in Supercup for four seasons.

They debuted with 306 BHP, later upped to 311 bhp with production of the Type 993 racers reaching 216 cars.

1998 911 GT3 Cup (Type 996)

Base model: Porsche 911 GT3
Debut: 1998 (Porsche Supercup)
Displacement: 3.6 litres
Power output: 265 kW (360 PS) to 287 kW (390 PS)
Units built: 873 (996 & 996 II)

Raced in the Porsche Supercup seasons 1998–2001 with a 360 bhp 3.6 litre boxer engine based on the block of the 911 GT1.

For the 1999 season engine output was increased to 272 kW (370 PS; 365 bhp) and 370 N⋅m (273 lbf⋅ft) at 6,250 rpm. For the 2001 season the GT3 Cup received modified aerodynamics including an enlarged rear wing and improved cooling.

2002 911 GT3 Cup (Type 996 II)

Raced in the Porsche Supercup seasons 2002–2004.

For 2002 the GT3 Cup received several changes based on the 996.2 Carrera and Turbo models, including Turbo-style headlights. The new body brought improvements to both aerodynamics and cooling.

Once again engine power output was increased – 280 kW (381 PS; 375 bhp) and 380 N⋅m (280 lbf⋅ft), with the new car also featuring improved transmission cooling and a lightened exhaust system.

For the car’s final front-line season in 2004 there were further upgrades. Engine output up to to 287 kW (390 PS; 385 bhp) at 7,200 rpm and 390 N⋅m (288 lbf⋅ft) at 6,500 rpm. Revised gear ratios saw fourth, fifth and sixth gears shortened. An 89-litre fuel tank was the first factory nod to a potential life in endurance racing capabilities.

And this was the first ‘Cup’ car with interior changes  made to enable the use of the HANS device.

2005 911 GT3 Cup (Type 997)

Base model: Porsche 911 GT3 and GT3 RS
Debut: 2005 (Porsche Supercup)
Displacement: 3.6 – 3.8 litres
Power output: 294 kW (400 PS) to 331 kW (450 PS)
Units built: 1,485 including 997 II

Raced in the Porsche Supercup seasons 2005–2009.

The 997-based Cup car featured significantly improved aerodynamics and lightweight CFRP parts, including doors, rear body panels, engine deck lid and rear wing. Parts of the suspension were adopted from the GT3 RSR.

2010 911 GT3 Cup 3.8 (Type 997 II)

The 2021 Cup car, now the seventh generation, was the first Porsche racer based around the Type 992 911 and was also the first Cup racer  to feature a wide turbo-spec body.

The new car retained the same basic engine as its predecessor but with power output increased from 485 to 510 bhp (362 to 380 kW; 492 to 517 PS). The new car is also tuned to run on synthetic fuels

The body of the previous 991.2 generation Cup car consisted of 70 per cent steel and 30 per cent aluminium. The ratio in the 2021 car has been switched.
