The Jaguar Mark IV was a saloon car built by the Jaguar company from 1945 to 1949. It was a relaunch of a pre World War II model made by SS Cars Ltd from 1936.

Before World War 2 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. Whilst the post war saloons were officially the Jaguar 1½ litre, 2½ litre etc the term 'Mark IV' was applied by the trade simply to differentiate them from the officially named Mark V.

[edit] SS Jaguar & Jaguar Mk IV 1½ Litre

The smallest model of the range originally featured a 1608 cc side valve Standard engine but from 1938 this was replaced by a 1776 cc overhead valve unit also from Standard.

Pre war the car was available as a saloon or drophead coupé but post war only the closed model was made. Up to 1938 body construction on all the models was by the traditional steel on wood method but in that year it changed to all steel. Performance was not a strong point but 70 mph was possible and the car featured the same well appointed interior as its larger brothers.

Again the engine was sourced from Standard but had the cylinder head reworked by SS. Unlike the 1½ Litre there were some drophead models made post war.

The chassis was originally of 119 inch (3023 mm) but gre by an inch (25 mm) in 1938 to 120 inches.

[edit] SS Jaguar & Jaguar Mk IV 3½ Litre

The 3½ Litre, introduced in 1938, was essentially the same body and chassis as the 2½ Litre but the larger 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.
