Of the more recent saloons, the most significant is the XJ (1968–1992). From 1968 on, the Series I XJ saw minor changes, first in 1973 (to Series II), 1979 (Series III), a complete redesign for 1986/1987 in XJ40, further modifications in 1995 (X300), in 1997 with V8-power (X308), and a major advance in 2003 with an industry-first aluminium monocoque-chassis (X350). The most luxurious XJ models carried either the Vanden Plas (US) or Daimler (rest of world) nameplates. In 1972, the 12-cylinder engine was introduced in the XJ, while simultaneously being offered in the E Type.
