This sensational racing car was developed from the W25 by Rudolf Uhlenhaut, who was only 30 years old, and the newly appointed technical director. It was a race winner from the start and the specification embodied the latest developments with unequal length wishbone front suspension, coil springs and telescopic dampers at the front. The rear suspension was by de Dion tube, torion bar springs and telescopic dampers. The engine was a straight eight of 5660 cc giving a stupendous 580 bhp and was fuelled by a concoction of methanol, ethyl alcohol and benzine. The braking was hydraulic with huge drums but even these struggled to retard such a powerful car. Another problem was tyres which were only 5.25 X 17 at the front and 700 x 19 at the rear and they frequently shredded. The other outstanding feature was the body style in aluminium over a tube frame. At a weight of 833 kg the power to weight ratio gave over 700 bhp per ton.
