Photographer extraordinaire Easton Chang has released his latest photo set, featuring the Auto Union Type C photographed within the new service department at Audi Centre Sydney.

The Type C was the pinnacle in development of a race car that had been designed by Ferdinand Porsche for use in the Grand Prix series. It ran its first race in 1934 according to the 750 kg weight limit formula (maximum mass, dry, without wheels and tyres).

The key design feature of the Auto Union Type C was the 16-cylinder engine positioned directly behind the driver (mid mounted engine). With weight distribution being another primary design element, the driver could sit lower with no drive shaft and the front-to-rear weight distribution was more even. Furthermore, the fuel tank was also located centrally for balance.

Despite these efforts, due to its heavy engine and small chassis, 60% of the weight still remained on the rear wheels. The Type C was the most successful German racing car within its series, winning three of the five Grand Prix races, half of the circuit races and all the hill-climbs that Auto Union entered.
