A Real Unicorn – Check Out this Rare 1984 Porsche 911 SC RS Gruppe B ‘Evolutionsserie.’

Famous auction house Broad Arrows will be hosting its final U.S.-based auction for the 2024 Calendar on October 12. About 80 premium cars will go under the hammer as part of the Chattanooga Motorcar Festival. One of the standout collector cars to be presented that day is undoubtedly this Porsche masterpiece – the 1984 Porsche 911 SC RS Gruppe B ‘Evolutionsserie.’

It ranks among the most intriguing models Porsche has ever made – certainly one of the rarest. Only 21 1984 Porsche Type 954, best known as the 911 SC RS, were produced. Like its much older relative, the 1967 Porsche 911 R, the 1984 911 SC RS was purpose-built for the race circuit while barely remaining street-legal.

As the name implies, this Porsche 911 found its place in the FIA Group B World Rally Championship. FIA homologation requirements laid out clear build specifications and modifications to turn a stock 911 SC into a rally-tuned race car. Weight reduction was a priority, and it involved using aluminum front doors, hoods and front fenders. Other materials included glass-reinforced plastic bumpers, unique to the SC RS cars, and a lack of undercoating. A minimalist interior layout that lacked a radio, power window, rear seat and sunroof helped cut the weight of the 911 SC RS to a scant 2,160 lbs (980 Kg)!

At the heart of the Porsche 911 SC RS is a type “930/18” 3.0-liter flat-six engine. Porsche offered the engine in two states of tune, one making 247 hp and the other making 266 hp. The one featured here was fitted with the more powerful option.

This Porsche 911 SC RS stands out even more from the exclusive group as the last 1984 model to roll off the assembly line. Chassis No. 21 was initially designated for South African importers Lindsay Saker. However, it was eventually delivered to Tycho Christian van Dijk, owner of the van Dijk Racing Team, in February 1984. The car featured a white exterior contrasted by a predominantly black cabin.

The 911 SC RS was prepped for racing with a hood-mounted rally light pod, radio equipment, a roof-mounted antenna, and a Jaeger rally computer. The original intention was to enter the car in a number of rally events that season. However, at the end of the year, the car had only been involved in a single race for reasons that probably included a lack of external sponsorship. Its singular outing was still something of a success, though; the Porsche 911 SC RS finished 14th as the highest-placed Porsche in a field that included 158 entrants.

In 2017, the consignor commissioned a report conducted by Jürgen Barth, an engineer and race car driver who was instrumental in the 911 Evolutionsserie program in 1983. Barth’s report confirmed that the car remained in outstanding condition with its original matching numbers engine and transmission, original interior, and components. The vehicle was again inspected as recently as March 2024 by Porsche San Diego while obtaining a Porsche Classic Technical Certificate (CTC). Chassis No. 21 has only covered 3,237 miles (5,209 km) over the last 40 years and remains in great condition.

It is also being offered with a load of ‘nice to haves’ that includes a factory Type 954 Technical Information and Spare Parts Catalog binder, copies of van Dijk’s Swiss registration documents, and digital copies of its internal Porsche Fahrzeugauftrag build sheet and a Porsche homologation document featuring information on all 21 Evolutionsserie 911 SC RS produced.

Porsches like this rarely pop up for sale, and this one is bound to generate a lot of attention. Broad Arrows estimates the 1984 Porsche 911 SC RS could fetch anything from $2.6 million to $3.5 million by the time the hammer goes down on the auction block. Any genuine Porsche enthusiast would still consider that a fair bargain.
