The Opel Senator A (facelift 1982) 3.0i CAT (156 Hp) Automatic represents a significant chapter in the history of European executive sedans. As Opel’s flagship model, the Senator was designed to compete in a highly contested segment, offering a blend of comfort, performance, and practicality. The A-generation, introduced in 1978, received a substantial refresh in 1982, bringing updated styling and technological improvements. The specific variant under review, the 3.0i CAT with its 156 horsepower engine and automatic transmission, was produced between 1985 and 1986, positioning itself as a refined, mid-range offering within the Senator lineup during the latter half of the A-generation’s production run. While never officially sold in the United States, the Senator played a crucial role in Opel’s strategy to challenge established premium brands in its primary European markets, particularly Germany and the UK, where it was also sold as the Vauxhall Senator.
Opel Senator A (facelift 1982): A Detailed Overview
The Opel Senator A was conceived as a larger, more luxurious alternative to the Opel Rekord, aiming to provide a vehicle capable of competing with the likes of BMW and Mercedes-Benz. The 1982 facelift brought significant improvements to the vehicle’s aesthetics and incorporated updated technology, enhancing its appeal in a competitive market. The Senator, in its various iterations, served as a statement of Opel’s engineering capabilities and design aspirations.
Engine & Performance
The 3.0i CAT variant of the Opel Senator A is powered by a 3.0-liter (2969 cm³) inline-six engine, internally designated as the C30LE. This naturally aspirated engine utilizes multi-port fuel injection and incorporates a catalytic converter, reflecting the growing emphasis on emissions regulations during the mid-1980s. The engine produces 156 horsepower at 5600 rpm and 226 Nm (166.69 lb.-ft.) of torque at 4200 rpm. This configuration delivers a smooth and responsive driving experience, well-suited for long-distance cruising.
Power is transmitted to the rear wheels through a four-speed automatic transmission, prioritizing ease of use and comfort over sporty driving dynamics. The Senator 3.0i CAT achieves a 0 to 60 mph acceleration time of 10.5 seconds and a top speed of 118.68 mph (191 km/h). Fuel economy figures for the era are estimated at 21 US mpg combined, 28.7 US mpg on extra-urban cycles, and 15.6 US mpg in city driving. These figures were typical for a large, executive sedan of the time.
Design & Features
The Opel Senator A (facelift 1982) features a traditional four-door sedan body style with a five-seat configuration. The 1982 refresh brought a more streamlined appearance, with revised front and rear fascias, updated lighting elements, and subtle aerodynamic enhancements. The vehicle’s dimensions – 190.51 inches in length, 67.8 inches in width, and 55.71 inches in height – contribute to a substantial and imposing road presence. A 105.63-inch wheelbase provides a stable and comfortable ride.
The interior of the Senator A is designed with passenger comfort in mind. The trunk offers a generous 25.25 cubic feet (715 liters) of cargo space, making it practical for family trips or business travel. The vehicle’s suspension system consists of an independent front suspension with McPherson struts, coil springs, and an anti-roll bar, coupled with an independent coil spring rear suspension featuring trailing arms and a transverse stabilizer. This setup aims to deliver a smooth and controlled ride. Braking is provided by ventilated discs at the front and solid discs at the rear, with an Anti-lock Braking System (ABS) available as a premium safety feature. Hydraulic power steering, utilizing a cone worm and recirculation balls, ensures effortless maneuverability.
