The Opel Senator is a full-size luxury automobile produced by the German automaker Opel, two generations of which were sold in Europe, from 1978 until 1993. The nameplate still continues with the Australian HSV Senator. A saloon, its first incarnation was also available with a fastback coupé body as the Opel Monza and Vauxhall Royale Coupe.
Through the international divisions of General Motors, it was also known in various markets as the Chevrolet Senator, Daewoo Imperial (in South Korea), Vauxhall Royale (until 1983) and Vauxhall Senator (which took the place of the Royale on Vauxhall models when the Opel brand was phased out from 1983).
The original Senator shared its platform with the smaller Opel Rekord, the latter being lengthened to make the Senator.
The second generation of that car, from 1987, shared its base with the Opel Omega, which was again lengthened to produce the Senator.
The Senator A (the "A" being used for differentiation here, but not a marketed name) was a lengthened version of the Opel Rekord E, complemented by a three-door fastback coupé version on the same platform called the Opel Monza, which was planned as a successor for the Opel Commodore coupé.
The original Senator and Monza were face-lifted in the end of 1982. In the UK, the Senator "A2" (as it is sometimes referred to) initially sold only as an Opel, before being re-badged for the UK (as a Vauxhall) in 1984. The A2 Monza was only sold as an Opel.
The facelifted car looked similar to its predecessor, with relatively minor changes: headlights increased in size, and chrome parts were changed to a matt black or colour-coded finish.
Interiors were improved, and engines changed. Now, straight-4 CIH 2.0E and 2.2E engines from the Rekord E2 were available. The 2.5E was given a new Bosch fuel injection system. The 2.8S was taken out of production, and the 3.0E and a new 3.0H engines were at the top of the range. The 3.0E received upgraded Bosch fuel injection. A 2.3-litre turbodiesel (shared with the Rekord) became available in 1984, and in November a supercharged version (Comprex) was shown. Going on sale in 1985, this very rare experimental version (1,000 units planned) were officially built by Irmscher rather than Opel. The Comprex offered 95 PS (70 kW) and a 172 km/h (107 mph) top speed; like the other diesels it had a pronounced bulge in the bonnet. From September 1985 until the end of production in late summer 1986 a catalyzed version of the 3.0E was available, with power down to 156 PS (115 kW).
