1972-1975 Opel Rekord D Caravan 1.7 (66 Hp)

The Opel Rekord D Caravan 1.7, producing 66 horsepower, was a station wagon (estate) produced between 1972 and 1975. It represented an entry-level offering within the broader Rekord D range, which spanned from 1972 to 1977 and was built on the GM’s H-platform. The Caravan body style, specifically, offered a practical and spacious alternative to the sedan, catering to families and those requiring increased cargo capacity. This variant occupied the lower end of the performance spectrum for the Rekord D, prioritizing affordability and fuel economy over outright speed. It was positioned below the more powerful 1.9 and 2.1-liter engine options, and significantly differed from the later fuel-injected models.

Powertrain & Engine Architecture

The heart of the Rekord D Caravan 1.7 was the Opel CIH (Cylinderkopf-Integrierte Nockenwelle – camshaft integrated in the cylinder head) inline-four cylinder engine, specifically designated with engine code 17N. This 1,698 cc (103.62 cubic inches) engine featured a single overhead camshaft (SOHC) valvetrain with two valves per cylinder. The engine’s bore measured 88 mm (3.46 inches) and its stroke 69.8 mm (2.75 inches), resulting in a compression ratio of 8.2:1. Fuel delivery was managed by a single downdraft carburetor, a common setup for the time, prioritizing simplicity and cost-effectiveness. The engine produced a maximum power output of 66 hp (49 kW) at 5,300 rpm and 118 Nm (87.03 lb-ft) of torque between 2,000 and 3,100 rpm.

The 1.7-liter engine was typically paired with a four-speed manual transmission, driving the rear wheels. While an automatic transmission was available on some Rekord D models, it was less common with the 1.7-liter engine due to the lower power output and the desire to maintain reasonable fuel economy. The rear-wheel drive configuration was standard for the Rekord D series.

Engine Characteristics and Comparison

Compared to the larger 1.9 and 2.1-liter engines offered in the Rekord D range, the 1.7-liter engine was noticeably less powerful. The 1.9-liter engine, for example, produced around 90 hp, offering a significant performance boost. The 2.1-liter engines, particularly those with fuel injection, delivered even greater power and torque. The 1.7-liter engine’s lower output made it less suitable for high-speed cruising or frequent overtaking maneuvers. However, it offered a smoother, more relaxed driving experience, particularly in urban environments. The 1.7 was also generally considered more fuel-efficient than its larger counterparts, a key selling point for budget-conscious buyers.

Driving Characteristics

The Rekord D Caravan 1.7 with the four-speed manual transmission offered a fairly leisurely driving experience. Acceleration from 0 to 100 km/h (0 to 62 mph) took approximately 22 seconds, and 0 to 60 mph was achieved in around 20.9 seconds. The top speed was around 137 km/h (85.13 mph). The engine’s torque peak at 2,000-3,100 rpm provided adequate pulling power for everyday driving, but required downshifting for steeper inclines or when carrying a full load. The four-speed gearbox offered relatively wide gear ratios, prioritizing fuel economy over sporty performance. The rear-wheel drive configuration provided predictable handling, but lacked the stability of more modern front-wheel drive systems. The Caravan’s suspension, tuned for comfort, absorbed bumps and irregularities in the road reasonably well, but did not offer particularly sharp handling.

Equipment & Trim Levels

The Rekord D Caravan 1.7 typically came with a relatively basic level of equipment, reflecting its position as an entry-level model. Standard features generally included cloth upholstery, basic instrumentation (speedometer, fuel gauge, temperature gauge), and manually operated windows and door locks. The interior was functional and durable, but lacked the luxury appointments found in higher-trim models. Optional extras included a radio, upgraded upholstery, and a sunroof. The Caravan body style itself offered a significant amount of cargo space, making it a practical choice for families and those needing to transport large items. The rear seats could be folded down to further increase cargo capacity.

Chassis & Braking

The Rekord D Caravan 1.7 utilized a body-on-frame construction, a common practice for the time. The suspension consisted of independent front suspension with coil springs and a rigid axle rear suspension with leaf springs. The front brakes were disc brakes, providing better stopping power than the drum brakes used on the rear wheels. The steering was a recirculating ball system, offering relatively light steering effort but lacking the precision of more modern steering technologies. The curb weight of the vehicle was approximately 1,110 kg (2,447.13 lbs), contributing to its relatively modest performance. The drag coefficient of 0.50 was typical for vehicles of that era.

Market Reception & Comparison

The Opel Rekord D Caravan 1.7 was generally well-received as a practical and affordable family car. Critics praised its spacious interior, comfortable ride, and relatively low running costs. However, its modest performance was often noted as a drawback, particularly when compared to more powerful Rekord D models. Fuel economy was rated at 11.1 l/100 km (21.2 US mpg, 25.4 UK mpg, 9 km/l), which was considered reasonable for the time. Reliability was generally good, although the carburetor required periodic maintenance. In terms of competition, the Rekord D Caravan 1.7 faced rivals such as the Ford Taunus Turnier and the Volvo 145, all offering similar levels of practicality and affordability.

Technical Specifications

Legacy

The Opel Rekord D Caravan 1.7, while not the most powerful or technologically advanced version of the Rekord D, remains a fondly remembered classic among enthusiasts. Its simplicity and durability have contributed to a reasonable number surviving today, making it an accessible entry point into classic Opel ownership. The 1.7-liter engine, while requiring regular maintenance, is generally considered reliable. In the used car market, these vehicles are valued for their practicality, spaciousness, and nostalgic appeal. They represent a snapshot of 1970s automotive design and engineering, offering a driving experience that is markedly different from modern cars. The Rekord D Caravan 1.7 continues to be a popular choice for restoration projects and classic car rallies.
