L CIH fuel injected petrol became available in the CD trim. A 2.3 L diesel version was also available . A wider range of trim levels consisting of "L", "GL" and "CD" were also introduced at this time. A 2.0 L fuel injection engine was introduced for the 1984 model year and was replaced by a 2.2 L fuel injection engine for 1985. Mark II (1986–1994) Main Article: Opel Omega A Opel chose to name its 1986 replacement car in this segment Omega rather than Rekord. Vauxhall stayed with the Carlton name. On its launch in November 1986 the Vauxhall Carlton / Opel Omega saloon and estate range earned itself the accolade of European Car of the Year - the second Vauxhall/Opel product to achieve this distinction, two years after the Astra/Kadett won the accolade.

The Opel Omega A was offered with a large 2.4L Opel CIH engine in certain European markets, but this variant was never offered in the Carlton.
