The cars were marketed as the Jaguar 1½ litre, Jaguar 2½ litre and Jaguar 3½ litre with the Mark IV name later applied in retrospect to separate this model from the succeeding Mark V range. The range was a return to production of the SS Jaguar 1½ litre, 2½ litre and 3½ litre models produced by SS Cars from 1935 to 1940.[1] Before World War II the model name Jaguar was given to all cars in the range built by SS Cars Ltd with the saloons titled SS Jaguar 1½ litre, 2½ litre or 3½ litre and the two-seater sports cars the SS Jaguar 100 2½ litre or 3½ litre. In March 1945 the company name SS Cars Ltd was changed to Jaguar Cars Ltd.[2] All the Mark IVs were built on a separate chassis frame with suspension by semi-elliptic leaf springs on rigid axles front and rear. {{clear}}SS Jaguar and Jaguar 1½ Litre{{Infobox automobile| name = SS Jaguar 1½ Litre Jaguar 1½ Litre | image = SS Jaguar 1.5Litre (1937) (14268238138).jpg | caption = SS Jaguar sports saloon 1937 | production = 1935–1949 10,980 made[3] | engine = {{convert|1608|cc|l|1|abbr=on}} I4 {{convert|1776|cc|l|1|abbr=on}} I4 Standard | body_style = 4-door saloon 2-door drophead coupé | length = {{convert|173|in|mm|abbr=on|sigfig=3}}[3] | wheelbase = {{convert|112.5|in|mm|abbr=on|sigfig=3}} | width = {{convert|65.5|in|mm|abbr=on|sigfig=3}} | transmission = 4-speed manual | height = {{convert|60|in|mm|abbr=on|sigfig=3}}[5] }} 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 still from Standard who also supplied the four-speed manual transmission. 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 {{convert|70|mi/h|km/h|abbr=on|sigfig=3}} was possible: the car featured the same cabin dimensions and well-appointed interior as its longer-engined brothers.[4] Despite its lack of out-and-out performance, a report of the time, comparing the 4-cylinder 1½-litre with its 6-cylinder siblings, opined that the smallest-engined version of the car was "as is often the case ... the sweetest running car" with a "big car cruising gait in the sixties".[5] Mechanically operated brakes using a Girling system were fitted. {{clear}}SS Jaguar and Jaguar 2½ Litre{{Infobox automobile| name = SS Jaguar 2½ Litre Jaguar 2½ Litre | image =Jaguar 1936 - Flickr - mick - Lumix.jpg | caption = SS Jaguar sports saloon 1936 | production = 1935–1948 6281 made[4] | engine = {{convert|2664|cc|l|1|abbr=on}} I6 | body_style = 4-door saloon 2-door drophead coupé | length = {{convert|186|in|mm|abbr=on|sigfig=3}}[3] | wheelbase = {{nowrap|1935–1937: {{convert|119|in|mm|abbr=on|sigfig=3}}}} 1938–1948: {{convert|120|in|mm|abbr=on|sigfig=3}} | width = {{convert|66|in|mm|abbr=on|sigfig=3}} }} Again the engine was sourced from Standard but had the cylinder head reworked by SS to give 105 bhp.[4] Unlike the 1½ Litre there were some drophead models made post-war. The chassis was originally of {{convert|119|in|mm|abbr=on|sigfig=3}} but grew by an inch (25 mm) in 1938 to {{convert|120|in|mm|abbr=on|sigfig=3}}. The extra length over the 1½ Litre was used for the six-cylinder engine and the passenger accommodation was the same size. {{clear}}SS Jaguar and Jaguar 3½ Litre{{Infobox automobile| name = SS Jaguar 3½ Litre Jaguar 3½ Litre | image = 1947 Jaguar MK IV Limousine IMG 0925 - Flickr - nemor2.jpg | caption = Jaguar sports saloon 1947 | production = 1937–1948 3162 made[4] | engine = {{convert|3485|cc|l|1|abbr=on}} I6 | body_style = 4-door saloon 2-door drophead coupé | length = {{convert|186|in|mm|abbr=on|sigfig=3}}[3] | wheelbase = {{convert|120|in|mm|abbr=on|sigfig=3}} | width = {{convert|66|in|mm|abbr=on|sigfig=3}} }} The 3½ Litre, introduced in 1938, was essentially the same body and chassis as the 2½ Litre but the larger 125 bhp [4] 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. References1. ^Pre and Post war 1.5/2.5/3.5L Models, www.jag-lovers.org 2. ^S.S. Cars Limited.
