This is part three of a five-part feature on the 125 most significant and influential car designs as chosen by former technical editor, Jake Venter. Most models of this era gradually grew more refined because a reduction in noise, vibration and harshness was seen as a major selling point (a trend which continues to this day). Many European makes adopted independent rear suspension, but this often made the cars tail happy. Independent front suspension slowly gained ground on both sides of the Atlantic, which led to an improvement in comfort and road- holding. The USA is represented by only the Jeep and the Oldsmobile. I could have chosen a post-war Jeep and put it in part four of this series, but it belongs to this era because of the dated technology. Most American models were not changed in any significant way since 1935 and the majority were still fitted with inefficient side-valve engines.
This is part two of a five-part feature on the 125 most significant and influential car designs as chosen by former technical editor, Jake Venter. This period can be divided into two distinct phases. Up to 1930, the lessons learned during the First World War, combined with design details taken from aero-engine practice, resulted in very exciting cars. However, once the effect of the Wall Street share crash in 1929 and the ensuing Great Depression became apparent, many designers curbed their technical expertise and returned to side-valve engines that were inexpensive to produce and maintain. For example, Mercedes-Benz went from overhead camshafts in the early ‘20s to side valves for its smaller cars. Even the 320 series chassis that featured some glamorous bodies was fitted with side-valve engines until the start of the Second World War.
