220bhp version of the 3.8 engine in the last of the big separate-chassis saloons, plus all-disc brakes and power-assisted steering which makes the IX more manageable than the earlier cars. Usual choice of transmissions, though automatics now in the majority. 12-14mpg, alas and the usual rust problems.
