An extraordinary 1966 Porsche 906 Carrera 6, one of only 65 produced, is now up for sale through RM Sotheby’s. Commissioned by Italian amateur racer and hillclimb specialist Ermanno Spazzapan, a passionate motorsport enthusiast who competed under the pseudonym “Mann,” chassis 906-115 quickly proved its competitive potential. Completed at Zuffenhausen on March 9, 1966, the car was ordered by Spazzapan, a devoted Porsche competitor who had previously raced a 356B 2000GS and a 356 Carrera Abarth GTL in Italian national events during 1964 and 1965.
Engineered as a lightweight successor to the 904, the Porsche 906 Carrera 6 featured a multi-tubular frame and unstressed fiberglass bodywork to minimize weight. The vehicle was powered by a 2.0-liter Type 901/20 six-cylinder engine which included a sand-cast magnesium Elektron crankcase, a forged steel crankshaft together with titanium connecting rods and forged alloy pistons and employed dry-sump lubrication. A cutting-edge powertrain generating 210 horsepower enabled the 906 to challenge larger-displacement competitors effectively.
The Porsche 906 achieved notable racing success through its class win at the 1968 Imola 500 Kilometers and third-place class finish at the 1967 Circuito del Mugello. European racing events brought the Porsche 906 to Vallelunga, Mugello, and Innsbruck circuits before it was acquired by private collectors.
After a successful racing career, it was sold to Porsche enthusiast Bernd Becker, who kept it from 1977 to 2001. This well-preserved car still has its original gearbox and GRP body panels. It recently got a thorough servicing by Road Scholars in Durham, NC, and comes with its original Kardex, an expired FIA Historic Technical Passport, and a detailed report from Porsche expert Jürgen Barth. The 906 is up for grabs through RM Sotheby’s private sales. Who’s ready to make it theirs?
