The Opel Rekord D 2.1 D (60 hp) was a diesel-powered variant of the Rekord D, produced between 1972 and 1977. Positioned as the economy-focused model within the Rekord D range, it offered a more fuel-efficient alternative to the gasoline-powered engines. The Rekord D itself was a significant model for Opel, representing a move towards more modern styling and engineering, built on the platform designated as the D-body. This particular diesel version aimed to appeal to buyers prioritizing fuel economy and durability over outright performance, particularly in markets where diesel fuel was more affordable and readily available.
Powertrain & Engine Architecture
The heart of the Rekord D 2.1 D was the 21D engine, a 2.1-liter (2068 cc) inline-four cylinder diesel engine. This engine utilized precombustion chamber injection, a common diesel technology of the era. Unlike direct injection, precombustion chambers housed a glow plug and a small auxiliary combustion chamber where fuel was initially ignited, then used to ignite the main combustion chamber. This system aided in cold starting and reduced engine noise compared to earlier diesel designs. The engine featured a single overhead camshaft (SOHC) valvetrain with two valves per cylinder. The bore and stroke measured 88 mm (3.46 in) and 85 mm (3.35 in) respectively, resulting in a compression ratio of 22:1 – typical for diesel engines of the time. The engine required 5.5 liters (5.81 US quarts) of engine oil, specified to Opel’s standards for the period. The cooling system held 10.6 liters (11.2 US quarts) of coolant.
Transmission
The Rekord D 2.1 D was primarily equipped with a four-speed manual transmission. While an automatic transmission was available on some Rekord D models, it was not commonly paired with the 2.1 D engine due to the engine’s relatively low power output and the added weight and complexity of the automatic gearbox. The manual transmission was designed to maximize the available torque, providing reasonable acceleration and highway cruising capability, albeit without the refinement of more modern gearboxes.
Driving Characteristics
The 2.1 D engine produced 60 horsepower at 4400 rpm and 118 Nm (87.03 lb-ft) of torque at 2500 rpm. This resulted in a leisurely driving experience. Acceleration from 0 to 100 km/h (0-62 mph) took approximately 23.5 seconds, and 0 to 60 mph required around 22.3 seconds. The top speed was limited to 135 km/h (83.89 mph). The engine’s strength lay in its torque delivery, making it suitable for hauling loads and navigating hilly terrain, but it lacked the responsiveness of the gasoline-powered Rekord D variants. The four-speed manual transmission required careful gear selection to maintain momentum, especially when climbing hills or overtaking. Compared to the more powerful Rekord models, the 2.1 D prioritized fuel efficiency and durability over outright performance.
Equipment & Trim Levels
The Rekord D 2.1 D was generally offered in a relatively basic trim level, reflecting its position as the entry-level model. Standard features typically included cloth upholstery, basic instrumentation (speedometer, fuel gauge, temperature gauge), and a simple two-spoke steering wheel. The interior was functional and durable, prioritizing practicality over luxury. Optional extras included a radio, upgraded upholstery, and a vinyl roof. The body style was available as a two-door sedan and a four-door sedan, with the four-door being the more popular choice. The exterior trim was minimal, with chrome accents on the bumpers and window surrounds.
Chassis & Braking
The Rekord D 2.1 D featured a conventional rear-wheel-drive layout. The front suspension utilized independent coil springs and wishbones, while the rear suspension employed a live axle with leaf springs. This setup provided a comfortable ride, but handling was not particularly sporty. The braking system consisted of disc brakes on the front wheels and drum brakes on the rear wheels. The braking performance was adequate for the vehicle’s weight and power, but lacked the stopping power of more modern braking systems. The kerb weight of the Rekord D 2.1 D was 1210 kg (2667.59 lbs), with a maximum permissible weight of 1685 kg (3714.79 lbs). The car had a ride height (ground clearance) of 130 mm (5.12 in).
Market Reception & Comparison
The Opel Rekord D 2.1 D was generally well-received by buyers seeking an economical and reliable family car. Critics acknowledged its fuel efficiency – achieving around 8 l/100 km (29.4 US mpg) – but noted its lack of performance compared to the gasoline-powered Rekord D models. Compared to the 1.7 and 2.0-liter gasoline engines, the 2.1 D offered significantly better fuel economy but considerably less power. The diesel engine was also known for its durability and longevity, making it a popular choice for high-mileage drivers. The 2.1 D was often compared to other diesel-powered sedans of the era, such as the Mercedes-Benz W115, but offered a more affordable price point. The Rekord D 2.1 D’s simplicity and robust construction contributed to its reputation for reliability.
