MB Josef Ganz 1931Due to Daimler-Benzs wealth, it had the largest workforce of experienced engineers. They constructed a small batch bare running chassis in a matter of a few weeks. The backbone chassis were fitted with all-round independent leaf spring suspension and a water-cooled 1,2 L four-cylinder engine, which produced 18 kW (25 hp), mounted behind the rear swing axles.A small streamlined steel body was later mounted on all chassis. A batch of Mercedes-Benz 120H (Heckmotor, Rear Engine) prototypes was completed. After a series of harsh road tests, the prototypes were proven to be successful. Daimler-Benz decided to renew the contract with Ganz for the development of another rear-engined roadster.Ganz was later contacted by Zundapp-Werke GmbH, Zundapp for short, a German motorcycle manufacturer in Nurnberg, in September about developing a small economy car. There was a problem. Zundapp wanted Ganz to develop a water-cooled five-cylinder radial engine for the car. Ganz , who specialised in building cyclecars around an existing motorcycle engine, had no experience in that field, was unable to offer his services. Consequently, the contract was never signed. However, by Oktober, Porsche was contracted by Zundapp for the development. the construction of the backbone chassis of the 170 H (W 28) with a rear cross-section to take up the gearbox (in front of the rear axle) and the engine (behind the rear axle).
Standard Superior_chassis-1933 Josef Ganz In the summer of 1932, director Wilhelm Gutbrod of the Standard Fahrzeugfabrik in Ludwigsburg made contact with Josef Ganz to discuss the development of a small Volkswagen based on his 1931 Maikafer prototype and various patents. An agreement was reached and a prototype was constructed and tested in the fall of 1932. Like the Maikafer, the Standard prototype featured a central tubular chassis with a mid-mounted engine and independent wheel suspension with swinging rear half-axles. As described in one of Ganzs patents, the two-cylinder two-stroke engine was mounted horizontally, in front of the swinging rear half-axles, on side of the tubular chassis with the gearbox on the other side. In February 1933, the Standard Fahrzeugfabrik introduced the pre-production model of the new Standard Superior at the Berlin motor show. The revolutionary chassis was fitted with a simple Beetle-shaped bodywork, constructed from wood and finished in artificial leather. While the chassis construction, based on the many patents of Josef Ganz, was praised for its revolutiory design, the bodywork was critized for being a little unpractical. Standard reacted to the criticism and developed an improved body for the production model.
Ledwinka's signature car, the car that set the pattern for subsequent models, was the Type 11 of 1923. It was the first commercially successful application of the central tube frame, which gave far better torsional and bending rigidity than the ladder frames then in vogue. As Ledwinka applied the principle, all forces engine torque reaction, rear-wheel braking and acceleration, and steering inputs -- were taken out through the tube. The body work merely had to support its own weight and the weight of the passengers.
