Continuing a tradition established by the legendary 2.8- and 3.0-liter 911 Carrera RSRs of the early 1970s, the 964 Carrera RSR 3.8 represented Porsche’s return to production-based GT racing dominance on the world’s stage.

Developed by the Porsche Motorsport department in Weissach, Germany, the Carrera RSR 3.8 was a purpose-built competition version of the 964 model, which had been introduced in 1989 as a thoroughly revised rendition of the classic 911 platform. Built to compete in European GT racing and the North American Supercars Series, the RSR 3.8 was evolved from the already successful 964 Carrera RS and Cup models and proved to be a winner from the outset. Highlights of the RSR’s illustrious racing career include overall victories at the 24 Hours of Spa, 24 Hours of Interlagos, and Suzuka 1000 Km, as well as class wins at the three leading international endurance races: Le Mans, Sebring, and Daytona.

Technically, the Carrera RSR 3.8 featured a special seam-welded body shell with lightweight aluminum doors and front lid, aggressive front and rear spoilers, a welded-in Matter roll cage, and the barest of racing essentials, contributing to a dry weight of just 2,675 pounds. Benefiting from Porsche’s decades of endurance racing experience, the chassis was equipped with uprated suspension, Turbo S brakes, center-lock Speedline wheels, and full racing equipment as standard, including a fuel cell, fire-suppression system, and Recaro racing seat with six-point Schroth harness. At the heart of the RSR was the naturally aspirated 3.8-liter M64/04 engine, conservatively rated 325 hp at 6,900 rpm, which was driven to the rear wheels via a five-speed transaxle with 40% limited-slip differential. Road tested in period by Car and Driver magazine, a 964 RSR recorded a 0–60 mph sprint in just 3.7 seconds, with a 12.1-second quarter-mile time and 181 mph top speed.

During 1993 to 1994, Porsche built just 51 examples of the Carrera RSR 3.8, together with 55 road-going RS 3.8 models to satisfy FIA homologation requirements. Today, these factory-built Porsche race cars are among the most sought-after GT machines of the 1990s, boasting a thoroughbred bloodline, successful competition record, and exclusivity in numbers.

As documented in the definitive book Porsche 964 Carrera RS 3.8, this RSR, chassis 496090, was delivered to its first owner, Walter Scheuermann of Memmingen, Germany, on December 15, 1993. Ordered direct through Porsche’s customer racing department, this RSR was specified in Guards Red and equipped with ADAC GT-type exhaust, a long-range 120-liter fuel tank, Le Mans gear ratios, air jacks, and a passenger seat.

One of several 964 RS and RSRs purchased new by Mr. Scheuermann, 496090 was never entered in competition. Instead, it was sold to exotic car specialist Garage Le Mans of Osaka, Japan, and carefully maintained as a featured display in the company’s showroom for nearly two decades.

In 2013, Porsche specialist David Mohlman purchased the RSR and imported it to the US. Soon after its arrival, the Porsche was sold to the current owner, a prominent American collector with a passion for historic endurance racing cars. During the consignor’s ownership, the 964 RSR was displayed at Rennsport Reunion V in September 2015. A photograph of the RSR taken at this event appears in the car’s entry in Porsche 964 Carrera RS 3.8, together with the author’s note, “PS496090 is likely to be the lowest mileage RSR in existence – and one of only two cars painted Guards Red.”

At the time of cataloguing, the odometer displayed just 19 km and the Porsche presents in virtually as-new condition in all respects, having received only necessary fuel-system maintenance and oil changes since its delivery to its first owner nearly three decades ago.

This ultra-rare Guards Red 964 Carrera RSR 3.8, collector-owned from new and preserved in exceptional time capsule condition, is undoubtedly among the finest surviving examples of a rare breed.

Never before offered for public sale and not exhibited since its appearance at Rennsport Reunion V, this sensational RSR offers discerning collectors a unique opportunity to acquire one of the most significant air-cooled Porsches of the modern era, with a provenance and specification that would be impossible to duplicate.
