Background
The 1973 Porsche 911 Carrera RS Lightweight (RS 2.7) is one of the most significant cars in Porsche history because it marked a turning point where the road-going 911 became a dominant platform for international motorsport. Porsche originally built the Carrera RS to homologate the 911 for Group 4 racing, which required the company to produce a minimum number of street-legal cars before the race version could compete. To maximize performance, Porsche created the Lightweight (M471) specification, which removed sound deadening, rear seats, and other non-essential components, while using thinner steel panels and lightweight glass. The result was a dramatically lighter car powered by a 2.7-liter flat-six producing about 210 horsepower.
The competition version, known as the 911 Carrera RSR, quickly proved the concept on the track. In 1973, the RSR achieved a landmark victory at the 24 Hours of Daytona, scoring an overall win against much larger prototype race cars. This triumph demonstrated that the 911’s rear-engine layout and lightweight engineering could compete at the highest level of endurance racing. The success of the Carrera RS established a blueprint for future Porsche race cars. It directly influenced later competition models such as the 911 RSR, 934, 935, and modern GT racing 911s. More importantly, it cemented the idea that a lightweight, track-focused 911 derived from a road car could become a world-class endurance racer.
Chassis 9113601572
This 1973 Porsche 911 Carrera RS Lightweight (M471) is one of just 200 built and a standout example in ultra-rare Glasurblau (Glacier Blue)—one of only 16 ordered in this shade. A matching-numbers car, it has had just two custodians since 1979 and comes with comprehensive documentation, including its original German Fahrzeugbrief and Pflegepass service book.
Originally delivered to Glöckler Porsche in Frankfurt with a limited-slip differential, it underwent extensive recommissioning between 2015 and 2017 without ever being fully restored. This exceptional RS Lightweight is currently listed for sale on Broad Arrow Private Sales with an asking price of $1,278,000.
The 911 Carrera RS was developed for FIA Group 4 GT homologation. Porsche initially planned 500 units, using stripped-down RSH forms to meet weight requirements before factory-fitting M471 Lightweight or M472 Touring options for road use. Overwhelming demand led to a total production of 1,580 units, including 200 M471 Lightweights, which remain the most sought-after variants today for collectors.
Chassis 9113601572 is a late third-series car, the 19th from the end and the third-to-last Lightweight built. Its Glacier Blue finish, black interior, lightweight seats, and optional LSD make it exceptionally rare. First delivered to Jürgen Krzikalla in Berlin, it was later acquired by Udo Schlüter, who raced it in local slaloms and Nürburgring 24 Hours events, making period modifications like a roll bar and wider wheels. In 1979, it passed to Klaus Völkmann, who cared for it for 36 years, including a repaint in its original color and limited use.
Since 2015, it has been with its fifth owner, with just c. 72,000 km recorded. Recommissioning preserved key original elements: glass, trunk and engine paint, transmission tunnel bracing, and aluminum “ducktail” spoiler. The original 2.7-liter MFI flat-six was overhauled, and brakes, suspension, and tires updated.
