Powertrain and Performance of the Opel Senator A (facelift 1982) 2.3 TD (86 Hp) Automatic

At the heart of the Opel Senator A (facelift 1982) 2.3 TD (86 Hp) Automatic lies a robust 2.3-liter (2260 cm³ or 137.91 cu. in.) inline four-cylinder turbocharged diesel engine. This powerplant, designated as an Internal Combustion Engine (ICE), was a notable feature for an executive car in the mid-1980s, offering a compelling blend of fuel economy and usable torque. The engine employed a Single Overhead Camshaft (SOHC) valvetrain with two valves per cylinder, a common and reliable configuration for diesel engines of that era. Fuel delivery was managed by a precombustion chamber injection system, contributing to smoother operation and reduced diesel clatter compared to direct injection systems of the time, enhancing the executive driving experience.

This turbocharged unit produced a respectable 86 horsepower at 4200 rpm, which was a solid figure for a diesel engine in its class during the mid-80s. More importantly for an executive cruiser, it delivered a substantial 189 Nm (139.4 lb.-ft.) of torque across a broad and accessible rev range of 2200-2400 rpm. This ample torque, available at relatively low engine speeds, made for relaxed driving and confident overtaking, particularly on highways – a key requirement for a car designed for long-distance travel. The engine’s compression ratio stood at a high 23:1, typical for a diesel, ensuring efficient combustion.

Power was delivered to the rear wheels via a 4-speed automatic transmission, emphasizing comfort and ease of driving over outright performance. While the automatic gearbox provided smooth shifts, the vehicle’s acceleration figures reflected its focus on economy and comfort rather than sporty dynamics. The Senator A 2.3 TD accelerated from 0 to 60 mph in approximately 17.6 seconds, with 0 to 62 mph (100 km/h) taking 18.5 seconds. The maximum speed was rated at 101.9 mph (164 km/h), making it perfectly capable of sustained highway cruising at European speeds.

One of the core strengths of this diesel variant was its fuel efficiency. The combined fuel consumption was an impressive 7.6 liters per 100 kilometers, translating to approximately 30.9 US miles per gallon. This efficiency was a significant selling point, offering considerable savings on fuel costs, especially for high-mileage drivers. The vehicle’s weight-to-power ratio stood at 16.6 kg/Hp (60.4 Hp/tonne), and its weight-to-torque ratio was 7.5 kg/Nm (132.6 Nm/tonne), indicating a well-balanced package for its intended purpose. The 75-liter (19.81 US gallon) fuel tank further enhanced its long-range capabilities, allowing for extended journeys between fill-ups.

Design and Features

The Opel Senator A (facelift 1982) presented itself as a classic four-door, five-seat sedan, embodying the conservative yet refined design language prevalent in executive cars of its era. The facelift introduced more contemporary styling cues, including revised front and rear fascias, updated lighting, and a generally smoother aesthetic that subtly improved its aerodynamic profile, evidenced by a drag coefficient (Cd) of 0.39. While not revolutionary, this design ensured the Senator remained competitive and appealing in its segment.

Measuring 190.51 inches (4839 mm) in length, 67.8 inches (1722 mm) in width, and 55.71 inches (1415 mm) in height, the Senator A was a substantial vehicle, providing ample interior space for five occupants. The generous wheelbase of 105.63 inches (2683 mm) contributed significantly to ride comfort and stability, particularly important for long-distance travel. Inside, the cabin was designed for comfort and functionality, featuring plush seating and a well-appointed dashboard with clear instrumentation.

Practicality was another strong suit. The trunk space was remarkably generous, offering a maximum capacity of 715 liters (25.25 cu. ft.), making it highly suitable for business travelers or families requiring significant luggage capacity. The vehicle’s kerb weight was 3141.59 lbs (1425 kg), with a maximum permissible weight of 4321.06 lbs (1960 kg), allowing for a substantial payload of 1179.47 lbs (535 kg).

From a chassis perspective, the Senator A featured a sophisticated setup for its time. It was equipped with ventilated disc brakes at the front and disc brakes at the rear, providing effective stopping power for a vehicle of its size and weight. The rear-wheel-drive architecture, typical of executive sedans, offered balanced handling and a classic driving feel. The minimum turning circle of 35.43 feet (10.8 m) ensured reasonable maneuverability despite its considerable length. The ride height of 5.51 inches (140 mm) provided sufficient ground clearance for varied European road conditions.
