Opel Senator 3.0i 24V
The Opel Senator was General Motors' attempt to compete with BMW and Mercedes-Benz in the European executive sedan market. Produced in two generations — the angular Senator A (1978-1986) and the more refined Senator B (1987-1993) — it offered a compelling combination of performance, comfort, and value that earned it respect even from die-hard BMW and Mercedes enthusiasts.
The definitive Senator was the B-series with the 3.0-liter 24-valve inline-six engine, producing 204 hp. This was one of the finest engines Opel ever produced — a smooth, free-revving unit with a characterful exhaust note and strong mid-range torque. At 240 km/h, the Senator 3.0i 24V could genuinely worry BMW 535i and Mercedes 300E owners on the autobahn.
The Senator B was a handsomely styled car. Designed by Wayne Cherry's team at Opel, it had clean, aerodynamic lines with a low drag coefficient for its era. The interior was well-equipped and comfortable, with leather seats, electric adjustment, climate control, and a comprehensive instrument cluster. Build quality was good — not quite at BMW/Mercedes levels, but significantly better than other GM products of the era.
The chassis was conventional but effective. The double-wishbone front suspension and semi-trailing arm rear provided a balanced handling character with good ride comfort. The steering was direct and well-weighted, and the brakes were adequate for the car's performance. An Irmscher-tuned version, developed by Opel's unofficial tuning partner, added sportier suspension, body modifications, and increased power.
The Senator was also sold as the Vauxhall Senator in the UK, where it found a loyal following among those who wanted executive car performance without the premium German brand price tag. Police forces across Europe used the Senator as a highway patrol car, testament to its high-speed capability and reliability.
Despite its qualities, the Senator never achieved the sales or prestige of its BMW and Mercedes rivals. GM's decision to discontinue the model in 1993 — without a successor — marked the end of Opel's ambitions in the luxury sedan segment. Today, surviving Senators are appreciated by a small but dedicated enthusiast community who recognize the car as one of the great underrated executive sedans.
Survivors are uncommon, particularly the Senator B 3.0i 24V. Rust is the primary concern — check sills, floor pans, inner fenders, and boot floor. The 3.0L 24V engine is robust but the timing chain and guides should be inspected on higher-mileage cars. The ZF automatic transmission is generally reliable but fluid changes are essential. Electrical components can be troublesome on neglected cars. Parts availability is reasonable through Opel specialist suppliers. Senator Bs are more desirable than Senator As. The Irmscher version is rare and commands a premium. Service history is important as many surviving cars have been poorly maintained.
Approximately 151,000 Senators produced across both generations (A and B). The Senator A (1978-1986) used 2.5L and 3.0L engines in various states of tune. The Senator B (1987-1993) received the advanced 24-valve engine and a comprehensive redesign. Also sold as the Vauxhall Senator in the UK and the Holden Commodore/Calais in Australia (using the same platform). The Irmscher-modified version was available through select dealers.
