Model History:
The early 1970s marked the culmination of Porsche’s dominance during the prototype era and the beginning of a works racing program based on the 911. In 1973, the 911 Carrera RSR won the Targa Florio outright, defeating factory-entered sports racing prototypes. The following year, an experimental RSR Turbo entered by the Porsche Martini works team placed 2nd overall at the 24 hours of Le Mans. These successes led Porsche to develop two new state-of-the-art 911-based racing cars to compete in the FIA World Championship for Makes.
Introduced for the 1976 season, the 934 was Porsche’s Group 4 variant of the all-new turbocharged 930 – a factory-built racing machine that maintained close ties to its road car counterpart. For Group 5, the so-called Silhouette formula, Porsche developed the 935, an evolution of the RSR Turbo, featuring independent coil-spring suspension, aerodynamic fiberglass bodywork, and a powerful turbocharged flat-six. In its debut season, the new Martini-liveried works 935s captured the Group 5 championship, ushering in an exciting new era for Porsche.

Between 1977 and 1979, Porsche developed special versions of the 935 for the works team and produced 37 production cars for customer use. Meanwhile, several private teams began to develop their own version of the 935, building highly specialized cars from factory-supplied body shells. Of all the independently constructed 935s, the most successful were the mighty K3s built by the Kremer Racing Team in Cologne, Germany.
Over a period of nearly 40 years, Erwin and Manfred Kremer developed, built, and campaigned Porsche racing cars that won many of the top prizes in endurance racing. Established in the early 1960s, the team had, by the mid-1970s, achieved considerable success at the 24 Hours of Le Mans and in the German National Championship.
Soon after Porsche debuted the 935, Kremer Racing developed their own version, the 935 K, which they entered in the World Championship for Makes. An improved K2 appeared in 1977, but it was the K3 that took the racing world by storm. Introduced in 1979, the K3 took its inspiration from Porsche’s groundbreaking 935/77 and included many similar features. Aerodynamically, the K3 employed advanced Kevlar composite bodywork, designed in conjunction with Eckerhard Zimmerman’s Design Plastics company, and made use of running board rocker panels, a raised rear roof, and Kremer-developed wing for increased downforce.
Beyond its exotic bodywork, the K3 featured a strengthened and lightened chassis; massive, ventilated disc brakes; and an inverted gearbox, which lowered the car’s center of gravity, made it easier to change ratios, and put less strain on CV joints. Perhaps the K3’s most significant innovation was its air-to-air intercooler, which greatly improved power output and reliability. In 3.2-liter form, the K3 produced a staggering 800 bhp at 1.7 bar of boost in qualifying trim, with 740 hp available at a more reliable 1.4 bar.
Unsurprisingly, the 935 K3 achieved tremendous success at the highest levels of international endurance racing. In 1979, the Kremer Racing K3 won the 24 Hours of Le Mans outright. In 1980, Dick Barbour Racing won the 12 hours of Sebring with a K3. Later that year, K3s helped Klaus Ludwig capture the German National Championship and John Fitzpatrick win the IMSA GTX title.
Specific history of this car:
The 935 K3 presented here, chassis 000 0010, was purchased new by Ted Field’s legendary Interscope Racing Team and marked the first of three Interscope cars. Finished in the iconic Interscope colors – black with red, orange, and pink stripes – chassis 0010 debuted at Road Atlanta in 1980.
• 13 April 1980, Road Atlanta 100 Miles, Field, 14th
• 04 May 1980, Laguna Seca 100 Miles, Ongais, 23th
• 04 July 1980, Daytona, Field 250 Miles, Ongais, 4th
• 27 July 1980, Datsun 100 Miles, Ongais, 18th
• 21 September 1980, Atlanta 50 Miles, Field, Race 1: 8th, Race 2: 28th
• 30 November 1980, Daytona 250 Miles, Field, 49th
• 01 February 1981, Daytona 24h, Field, Minter, Ongais, 39th
• 21 March 1981, Sebring 12h, Field, Ongais, 44th
• 31 January 1982, Daytona 24h, Field, Ongais, Whittington, 62th
• 24 April 1983, Riverside 6h, Dyer, Pusey, DNF
• 10 July 1983, Brainerd 500 Kilometers, Pusey, Rude, DNF
After this accident, the chassis was damaged and the car was sold on Dennis Aase from Anaheim, USA. As the development of the 935 have continued over the years, the car was rebuilt to the even more radical space frame spec. The modified chassis that were mainly used in IMSA where lighter, offered a more radical and efficient aerodynamic and had a more balanced weight ratio. It is believed that these modifications were done by Paul Goral, who also entered 00010 at races again:
• 05 February 1985, Daytona 24h, Goral, DNS
• 24 March 1984, Sebring 12h, Goral Hayes-Harlow, 79th
• 25 November 1984, Daytona 3h, Goral, Hinze, 42th
• 23 March 1985, Sebring 12h, Goral, Wilson, 17th
At the end of 1987 the car was sold to Germany where it was entered by the lawyer Wolf Gregor in the German „Spezial Tourenwagen Trophy“ 1988. Only three years later, in summer 1991, the 935 was sold at auction to Wolfgang Kruse, who had the car on static display in his collection.
Ten years later, in 2001, the car was sold to historic racer Dr. Armin Zumtobel in order to finance the purchase of a historic Ferrari Formula 1 car.
In 2009 the Cologne based racing team, Kremer racing who built this car new, confirmed the authenticity of the vehicle and a HTP passport was issued by the FIA.
Dr. Zumtobel raced the 935 successfully for many years in a Apple livery until it was sold to another German collector who had the car completely restored back to the iconic Interscope livery. The car is now presented in race prepared condition and was only recently raced by three-time Le Mans winner Marco Werner at various Peter Auto events.
Over the past four decades, historians and collectors have come to regard the 935 as one of the all-time great racing Porsches. In various permutations, 935s were competitive for nine seasons, capturing outright victories at Le Mans, Daytona, and Sebring, as well as multiple FIA World Championships and numerous other national championships. Today, these Porsches are eligible for the best historic racing events and remain the cars to beat, especially in highly developed K3 form. Rare, significant, and visually impressive, 935s are also increasingly sought-after by organizers of leading concours and marque gatherings.
Not only is this K3 one of the last, most developed 935s, its Interscope Racing provenance, well-documented history, and outstanding vintage race record placed it among the very best examples of a rare breed. We feel honored to present this exceptional K3 and recommend it to any collector looking for a top-tier example of the legendary 935.
The car will be sold including an excellent, impressive history file and a full shake-down offered to the new owner.
