Ten years after the launch of the original XJ range in 1968 the Series III was introduced. Three engines were available; the six-cylinder 3.4 and 4.2-lires and the 5.3-litre V12. This was a time when Jaguar's image was at a low point but this was turned round and respect restored within a couple of years. There were range realignments in 1982 and 1983, when the Daimler name was dropped in Europe. The XJ40 replaced the six-cylinder cars in 1986 although the V12 cars remained in production.
