A 1976 Porsche 934/5 Kremer Group 4 Competition Coupé will be auctioned by Bonhams at this year’s Spa Classic Sale in Belgium, accompanied by a matching 1977 Volkswagen T2 Transporter.

The Porsche 935 was regarded as one of the most successful racing versions of the 911 ever to hit the track. It was prepared for the top-level Group 5 regulations, while a similar 934 was built specifically for the Group 4 racing. This 934/5 campaigned by the famed Kremer Racing team is the example of bridging the gap between the two. This rare Porsche competition model has raced in modern historic events between its Kremer days and its subsequent ownership by the respected racing driver Edgar Dören, who is also known as ‘Mr Porsche’ for his affinity with the Stuttgart marque.

The 1977 Volkswagen T2 Transporter features a similar Martini Racing livery and serves as a historic racing support vehicle. It is fitted with a 2.1-litre T4 engine from a Porsche 914, which breathes via twin 40 mm carburettors and is estimated to produce a very healthy 110 horsepower.

The Porsche 934/5 is expected to fetch up to €400,000, while the Volkswagen T2 Transporter is expected to be sold for at least €45,000. Both the vehicles will be auctioned at the Spa Classic Sale on May 21 at the Spa-Francorchamps circuit in Belgium.
