Page 1 of 1 For the 1984 season, Porsche jumped on the Group B bandwagon. While most other manufacturers first produced homologation specials to base their Group B on, Porsche could use the regulation production 911 SC as a starting point. As per the regulations, once a car was homologated for Group B, a more extreme 'evolution' version could be produced in a minimum run of 20 cars. Porsche just did just that and aptly dubbed the new rally car the 911 SC/RS.
Built around a lightweight shell, with unnecessary amenities stripped, the 911 SC/RS was fitted with high performance components sourced from previous Porsche competition cars. It boasted 917/30 derived brakes, Recaro seats previously used on the 935, a rear wing from the 911 Turbo and Fuchs alloy wheels. To keep the weight down, all panels not fixed to the shell like the doors were made from aluminium and the front and rear bumpers were made from fibreglass and Kevlar. Aluminium skid plates were fitted front and back to protect the underside of the car.
The 911 SC/RS was powered by a further evolution of the familiar three-litre flat-six. Dubbed the 930/18 in this particular guise, the engine featured a dry-sump system, forged pistons, more aggressive camshafts and a higher compression. Power increased accordingly from 204 bhp to 255 bhp in standard trim. An even more potent competition spec of the 930/18 pumped out 280 bhp at 7,000. This power was sent to the rear wheels through a five-speed manual gearbox that used the same clutch as the 911 Carrera RSR. A rear 40% limited slip rear differential was also fitted.
To level the playing field, the Group B regulations included a sliding scale for the minimum weight based on the engine displacement. For a naturally aspirated three-litre engine, the minimum was set at 960 kg. At 1,057 kg, the 911 SC/RS was not very close to the minimum but it was a whopping 300 kg lighter than the production car it was based on. Porsche offered the 911 SC/RS or Typ 954, as it was known internally, in plain white with black trim to customers for DM 188,100. While most cars were acquired by collectors, quite a few were used in rallies by privateers and five went to the works-backed Prodrive team.
Compared to the highly complex, four-wheel drive Group B cars from rivals Lancia and Audi, the 911 SC/RS was a rather more straightforward machine. Thanks to its light weight and rear-wheel drive only, it was best suited for tarmac rallies. Its debut, however, came at the Qatar International Rally early in 1984. Driven by Saeed al Hajri, the Rothmans liveried machine won straight out of the box. He would also win the second round of the Middle East Rally Championship. In Europe, Henri Toivonen scored six podium finishes in eight rounds of the European Rally Championship.
Among the subsequent highlights of the Group B Porsche's career was a second place finish in the Tour de France and a third in the Tour de Corse. Saeed al Hajri continued his winning ways in the Middle East, winning the championship in both 1984 and 1985. Further wins were scored in tarmac events like the Rallye Costa Smeralda. Porsche eventually produced 21 examples of the 911 SC/RS, with one earmarked for the Museum. Today, it is one of the rarest 911 variants and highly sought after. Page 1 of 1
