Vauxhall Senator B 2.6i (150 Hp)

The Vauxhall Senator B 2.6i (150 Hp) represents a significant chapter in the history of European executive sedans, a segment where understated luxury and robust engineering were paramount. Produced under the Vauxhall marque for the United Kingdom market from 1990 to 1993, this vehicle was essentially a rebadged version of the Opel Senator B, serving as General Motors’ flagship offering in Europe during its production run. Positioned as a direct competitor to executive vehicles from BMW and Mercedes-Benz, the Senator B aimed to combine sophisticated styling with reliable performance and a comfortable, spacious cabin. While not sold in the United States, its mechanical underpinnings and design ethos reflect the global engineering capabilities of General Motors, tailored specifically for the discerning European consumer. This generation of the Senator built upon its predecessor’s reputation for solidity and refinement, adapting to the evolving demands for enhanced safety, efficiency, and driving dynamics in the early 1990s. As a classic car today, it is remembered for its blend of traditional rear-wheel-drive architecture with contemporary features and a focus on long-distance cruising comfort, embodying the executive motoring ideal of its era.

Engine and Performance of the Vauxhall Senator B 2.6i (150 Hp)

At the heart of the Vauxhall Senator B 2.6i (150 Hp) lies a robust and well-regarded inline-six engine, designated by the code C26NE. This naturally aspirated, 2.6-liter (2594 cm³ or 158.3 cu. in.) gasoline powerplant was engineered for a smooth and refined power delivery, characteristic of executive sedans of the period. With two valves per cylinder and a multi-port manifold injection system, the engine produced a respectable 150 horsepower at 5600 rpm. This power output, coupled with its 220 Nm (162.26 lb.-ft.) of torque delivered at a relatively low 3600 rpm, ensured ample acceleration and flexible cruising capabilities. The longitudinal front-engine layout, driving the rear wheels, provided a balanced chassis and traditional executive car dynamics, appealing to drivers who valued a predictable and engaging driving experience.

The Senator B 2.6i was equipped with a 5-speed manual transmission, a choice that offered direct engagement for the driver and contributed to its performance credentials. This powertrain configuration allowed the sedan to reach a maximum speed of 132.35 mph (213 km/h), a commendable figure for a full-size executive car of its time. The vehicle’s weight-to-power ratio stood at 9.4 kg/Hp (106.8 Hp/tonne), while the weight-to-torque ratio was 6.4 kg/Nm (156.6 Nm/tonne), indicating a well-matched engine and chassis for its intended purpose. The engine’s oil capacity was 5.5 liters (5.81 US qt), and the cooling system held 10.5 liters (11.1 US qt) of coolant, emphasizing the robust engineering designed for reliability and endurance.

Beyond the engine, the Senator B’s performance was also influenced by its well-engineered chassis and suspension system. The front suspension featured an independent McPherson strut design with coil springs and an anti-roll bar, providing precise steering and good road holding. The rear utilized an independent coil spring setup, contributing to the car’s comfortable ride quality and stability, particularly important for long-distance travel. Braking performance was handled by ventilated discs at the front and solid discs at the rear, a capable setup for the car’s weight and speed. Critically for the early 1990s, the inclusion of an Anti-lock Braking System (ABS) was a significant safety feature, providing enhanced control during emergency braking maneuvers and highlighting the Senator B’s commitment to driver and passenger safety.

Design and Features of the Vauxhall Senator B

The design of the Vauxhall Senator B reflected the conservative yet elegant aesthetic popular in the executive car segment of the early 1990s. As a 4-door sedan with seating for five, its proportions were classic and well-balanced, emphasizing its role as a sophisticated family or business vehicle. The overall length of 190.75 inches (4845 mm), a width of 69.41 inches (1763 mm), and a height of 57.09 inches (1450 mm) provided a commanding presence on the road. The substantial wheelbase of 107.48 inches (2730 mm) was instrumental in delivering a smooth ride and generous interior space, particularly for rear-seat passengers, a hallmark of executive sedans.

Aerodynamic efficiency was also a consideration, evidenced by a relatively low drag coefficient (Cd) of 0.30. This figure was quite respectable for a large sedan of its time, contributing to both fuel efficiency and reduced wind noise at higher speeds, enhancing the overall refinement of the driving experience. The exterior styling was characterized by clean lines, a distinctive grille, and large glass areas, ensuring excellent visibility and an airy cabin feel. While specific luxury features are not detailed in the technical data, as a flagship executive model, the Senator B would have offered a comprehensive suite of comfort and convenience features for its era, likely including power windows, central locking, high-quality upholstery, and advanced climate control systems, all designed to create a premium environment for its occupants.

Practicality was also a strong suit of the Senator B. The trunk (boot) offered a generous 18.72 cu. ft. (530 liters) of storage space, making it highly capable for long journeys or family use. A fuel tank capacity of 19.81 US gallons (75 liters) ensured an extensive cruising range, further cementing its credentials as a comfortable and competent touring car. The vehicle’s kerb weight of 3097.49 lbs. (1405 kg) contributed to its solid road feel, while a maximum permissible weight of 4332.08 lbs. (1965 kg) highlighted its robust construction and load-carrying capability. Additional utility features included a maximum roof load of 220.46 lbs. (100 kg) and substantial towing capacities: 3747.86 lbs. (1700 kg) with brakes and 1587.33 lbs. (720 kg) without brakes, further underscoring its versatility. The car rode on 205/65 R15 tires fitted to 6J x 15 wheel rims, providing a balance of comfort, grip, and durability suitable for its executive mission. The minimum turning circle of 33.14 ft. (10.1 m) also ensured reasonable maneuverability for a vehicle of its size.
