1950 Cotura (Netherlands) - AllCarIndex

The Cotura is a sports car based on BMW technology that was built by Co van der Tuyn from Rotterdam. It is not clear whether he built two or three examples, because Kalkman's BMW special was also regularly referred to as a Cotura. Two Coturas were at least used on the circuit in the second half of the fifties, initially with Van der Tuyn himself at the wheel. One of the cars was equipped with a 1991 cc six-cylinder engine, originating from a BMW 328. The other example originally had a power source with a capacity of one and a half litres, which was reduced to enable participation in the class up to 1100 cc.

In its debut year 1950, Van der Tuyn even started his Cotura at the Nürburgring, where it won a place among the factory BMWs. B. Maasland and Hans van Dieten also drove the car. Rinus van der Tuyn died on 4 March 1954, after which the Coturas came into the hands of Joke Maasland and Hans de Mooy. It was already clear then that they would have to admit defeat to the more modern cars that appeared on the circuits. During the preliminary race for the 1958 Grand Prix, Rob Slotemaker started with an old Cotura. Despite starting at the back of the field, he managed to bring the car across the finish line as a winner one more time. The Cotura then disappeared from national racing. One example still exists. Unfortunately, the current owner replaced the original BMW engine with a more modern Mercedes model.
