Porsche
356 B Carrera GT "Dreikantschaber"

Why it matters

The Dreikantschaber ("triangular scraper") is an aluminium-bodied racing version of the 356 B Carrera 2, of which Porsche says only two were ever built. Lightweight construction brought it to 820 kg, 195 kg less than the road car. In 1963 Edgar Barth and Herbert Linge finished third overall in the Targa Florio and won the GT class with it, and Linge then became the first GT driver to lap the Nürburgring Nordschleife in under ten minutes.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The car was built in 1963 on the basis of the 356 B Carrera 2. At the 1963 Targa Florio Edgar Barth and Herbert Linge took third place overall and the GT-class win. Porsche's account of Linge's career confirms the result and names the car "Dreikantschaber", the 356 B Carrera GT. Three months after the Targa, Linge lapped the Nordschleife in under ten minutes with it.

Porsche Heritage and Museum has shown a Dreikantschaber at events such as the Solitude Revival in 2024.

Identification guide

How to tell an original from a replica or later conversion.

The wedge-shaped nose and the abrupt break in the roofline, which gave the car its nickname, distinguish it from every road-going 356 B. It is built on the 356 B Carrera 2 and weighs 820 kg. Porsche states that only two were made, so any further claimed Dreikantschaber contradicts the factory account.
