Overall Rating
Jaguar XK:
The Jaguar XK is an inline 6-cylinder dual overhead camshaft engine produced by Jaguar Cars between 1949 and 1992. Introduced as a 3. 4-litre, it earned fame on both the road and track, being produced in five hemispherical head displacements between 2. 4 and 4. 2-litres for Jaguar passenger cars, with other sizes being made by Jaguar and privateers for racing. A de-rated version was also used in certain military vehicles built by Alvis and Daimler.
Prior to World War II, SS Cars used three engines produced by the Standard Motor Company: a 1. 5-litre 4-cylinder and 6-cylinder engines of 2. 5- and 3. 5-litres. Sir William Lyons and his engine designers; William Heynes , Walter Hassan, Claude Baily, and Harry Weslake are widely reported to have discussed a new range of replacements whilst fire-watching on the roof of the SS factory in Swallow Road, Coventry, during German World War II bombing raids. Rather than developing prototype engines immediately after the war, it is claimed that Jaguar's wartime engine developments went far beyond mere discussion and design, extending to the construction and testing of several prototype engines as early as 1943....(Read more on Wikipedia)
