1937 Jaguar 3 1/2 litre
Before the Second World War the name Jaguar was the model name given to the complete range of cars built by SS Cars Ltd. The saloons were titled SS Jaguar 1½ litre, 2½ litre or 3½ litre. The two-seater sports car was titled the SS Jaguar 100 2½ litre or 3½ litre.
After the war the company name was changed to Jaguar Cars Ltd. Although the post-war saloons were officially the Jaguar 1½ litre, 2½ litre etc., the term "Mark IV" was sometimes applied retrospectively by the trade to differentiate them from the officially named Mark V.
The 3½ Litre, introduced in 1938, was essentially the same body and chassis as the 2½ Litre but the larger 125 bhp engine gave better performance but at the expense of economy. The rear axle ratio was 4.25:1 as opposed to the 4.5:1 on the 2½ Litre.
