The Opel Senator, produced from 1987 to 1993, was a large executive sedan designed to compete with the likes of the Mercedes-Benz W124 and BMW E32. This second generation of the Senator, known internally as the "Type A," represented a significant departure from its predecessor. It was built on a revised and stretched version of the Opel Omega platform, offering a more spacious and luxurious interior. Mechanically, the Senator was powered by a range of six-cylinder engines, including the 2.5-litre, 3.0-litre, and 3.0-litre "C30SE" units, with the latter being the most powerful option. These engines were mated to either a 5-speed manual or a 4-speed automatic gearbox. The Senator also featured a comprehensive suite of features for its time, including power steering, power windows, central locking, and air conditioning. Its sophisticated yet conservative styling, coupled with its robust engineering, made it a popular choice among those seeking a premium driving experience without the exorbitant price tag of its German competitors.

Despite its success in capturing a niche market, the Senator ultimately faced an uphill battle against the established German luxury brands. The Opel badge, while respected for its reliability and value, lacked the prestige and cachet of its rivals. Furthermore, the Senator's large size and thirsty engines became increasingly less desirable in the face of growing environmental concerns and rising fuel prices. While it was a competent and well-engineered vehicle, the Senator ultimately failed to achieve the same level of commercial success as its predecessor, leading to its discontinuation in 1993. The Opel Senator, however, remains a significant piece of automotive history, representing Opel's ambitious attempt to challenge the established order in the premium car segment. Its legacy lives on in the form of its successor, the Opel Omega, which further solidified Opel's position as a manufacturer of reliable and stylish cars.
