Garage44 Offers Three Porsche Four-Cam Carreras as a Single Collection

A trio of late-1950s and early-1960s Porsche 356 Carreras, each powered by the legendary four-cam engine, is being offered together by Garage44, spanning grand touring, competition and stripped-back Speedster specifications.

A collection of three Porsche 356 Carreras, each powered by the legendary four-cam boxer engine, is being offered together by Garage44 in a sale that traces the breadth of Porsche's early competition programme. The cars, spanning the late 1950s and early 1960s, represent three distinct interpretations of the Carrera ethos: high-speed touring, focused track use and a stripped-back driving machine.

The four-cam engine, designed by Ernst Fuhrmann, was deemed ready for production after just a couple of years of racing, and by 1955 it was made available in the 356A Carrera, named after the gruelling and deadly Carrera Panamericana road race. Each car in the collection is powered by a plain-bearing version of that engine, and each has been refurbished and refinished in its factory-specified colours. All three received mechanical attention from Jeff Adams of Speedsport Tuning, a four-cam specialist who learned the craft from a Porsche technician trained on these engines by the factory in period.

The most competition-focused of the trio is a 1960 Porsche 356B Carrera 1600 GT Coupe, chassis 110858, one of fewer than 50 Carrera GT Coupes produced for the 1960-61 model years. It retains its numbers-matching Type 692/3 plain-bearing four-cam engine, no. 95072, and is finished in Ruby Red over black. GT specification brought aluminium opening panels, Plexiglas windows, aluminium and steel wheels, an 80-litre fuel tank and 60mm front drum brakes. The car comes with FIA Historic Technical Papers and an extensive European vintage racing history through the 1980s and 1990s, including competition at the Nürburgring, Monza, Zolder and Mainz-Finthen. In 2019 it was selected by Porsche Cars North America for its corporate display at the Amelia Island Concours, and in early 2026 it received a comprehensive mechanical service by Adams and Speedsport Tuning.

The 1959 Porsche 356A Carrera GT Speedster, chassis 84945, is said to be one of only 14 Carrera GT Speedsters built with the Type 692/3 plain-bearing four-cam engine, and as a 1959 car it is among the last of the Speedster bodystyle. Finished in its original Silver Metallic over a black interior, it carries the lightweight, competition-oriented equipment that distinguished GT cars from standard production examples, including aluminium opening panels, aluminium and steel wheels, an 80-litre fuel tank and 60mm front drum brakes. Its body and metalwork were handled by Tom Caruso of Contour Metal, while the engine and mechanical systems were rebuilt by Adams. Its current engine, no. 95016, is just one digit away from its original, no. 95017. The car was Best in Class at the 2021 Greenwich Concours and scored 295.1 out of 300 points at the 2022 Porsche Club of America Parade Concours, also receiving the Gmünd Award and the Honorary Judge's Award.

Completing the set is a 1959 Porsche 356A Carrera 1600 GS Coupe, chassis 108186, one of just a few dozen Carrera GS Coupes produced for the 1959 model year and delivered new through Sonauto in Paris. It is finished in factory-correct Silver Metallic over a special-order red interior and is powered by engine 93133, a Type 692/2 plain-bearing four-cam that replaces its original unit, no. 93116, and is said to be of the same type originally specified. The Grand Sport name indicated a more refined touring intent, which at the time meant amenities such as a heater, leather seats, carpets, map pockets and chrome door pulls. The car received a high-quality restoration some years ago and its suspension and engine have been set up by Adams at Speedsport Tuning.

Taken together, the three cars illustrate a progression from high-speed touring to focused track use during one of the most technically ambitious periods in Porsche's early history. Each comes with documents attesting to its provenance. The cars from the 1-2-3 4-Cam collection began posting on Monday, September 14, with the second of the three going live later in the month, and a cinematic overview of the collection accompanies the sale.
