935 were mostly over, as it could hardly be modified to a groundeffect design even with a tube frame chassis, with the rear-mounted flat 6 prohibiting a diffuser, an issue which also affects modern 911 race cars. Only a handful of 935's remained, and the car was no longer competitive with the already developed GTP cars. The last major victory for the 935 was in the 1984 12 Hours of Sebring in the IMSA GTP class against purpose built prototypes. The 935 was seen in two races in the 1986 season. The 935 can still be seen on the track throughout North America and Europe in historic racing and hill climbs. The four-wheel-drive 959, and its racing counterpart 961, can be considered high-tech successors to the 935, but Group B never got a circuit racing series, and was only used in rallying before being banned there due to a fatal accident. The 1980s had few racing opportunities for turbocharged 911 cars, which often were fitted with 935-style bodywork. Being run by amateurs at the Nürburgring in VLN endurance and in the 24 hours race, they were often banned, or at least slowed down by rules. The 1990s 911 GT2 based on the 993 is also considered a successor to the 935, but BPR series and FIA GT rules required a higher weight, and intake restrictors limited power to , less than the first 935/76. The 911 GT1 with its mid-engine and lowered roof has a different concept, though. Starting in 2003, the turbo-charged Porsche 996 of Alzen set new records at the Nürburgring VLN endurance series (see List of Nordschleife lap times (racing)), with speeds reminding of the 935 era, despite it being also slowed down by minimum weight (1,350 kg) and limited boost. The Porsche 935 is still raced in championships alongside more modern cars, such as the GT Cup Championship, in which Richard Chamberlain pilots a 935 for CTR Developments in the GTO class. 935 (second generation - 2019) The second generation of the 935 based on the 991 GT2 RS, with bodywork resembling the 935/78, as a tribute to the 935/78. The LED taillights are shared with the 919 Hybrid LMP1 racer, side mirrors from the 911 RSR and titanium tailpipes hearkening back to the 1968 908/01. The car has a gearshift lever with laminated wood design, a carbon fibre steering wheel and the colour display from
