The Opel Kadett C Caravan 1.6 S Automatic, produced between 1977 and 1979, represented a practical and relatively affordable option within the broader Kadett C range. Positioned as a mid-range trim level for the Caravan (estate) body style, it offered a blend of family-oriented space and modest performance. The Kadett C, launched in 1972, was Opel’s response to changing market demands, offering a more modern and spacious alternative to its predecessor, the Kadett B. The Caravan variant, in particular, was popular in Europe as a versatile vehicle for families and businesses alike. This specific 1.6 S Automatic configuration aimed to provide a comfortable and convenient driving experience, albeit with a focus on economy rather than outright speed.

Powertrain & Engine Architecture
The heart of the Kadett C Caravan 1.6 S Automatic was the 1584cc (96.66 cubic inch) inline-four cylinder engine, designated as the 16S. This engine featured a relatively simple, pushrod-operated valve train with two valves per cylinder. Fuel delivery was handled by a single, down-draft carburetor – a common setup for the era. The 8.8:1 compression ratio was a compromise between performance and the fuel quality available in European markets. The engine produced 75 horsepower at 5000 rpm and 113 Nm (83.34 lb-ft) of torque. The three-speed automatic transmission was a General Motors-sourced unit, providing a more relaxed driving experience compared to the available four-speed manual. This automatic wasn’t known for its responsiveness or efficiency, but it catered to drivers prioritizing convenience.
Driving Characteristics
The 1.6 S Automatic Kadett Caravan wasn’t a performance car. Acceleration was leisurely, taking around 16.5 seconds to reach 62 mph. The automatic transmission, while offering ease of use, sapped some of the engine’s already modest power. Gear ratios were optimized for fuel economy and smooth cruising rather than quick acceleration. Compared to the manual transmission versions of the 1.6 S, the automatic felt noticeably slower. Even compared to other Kadett C variants like the 1.2, the 1.6 Automatic offered only a marginal performance improvement. However, the Caravan’s comfortable ride and predictable handling made it a suitable vehicle for everyday driving and longer journeys.
Equipment & Trim Levels
The 1.6 S trim level offered a step up in comfort and features compared to the base Kadett Caravan. Standard equipment typically included cloth upholstery, a basic instrument cluster, and a two-spoke steering wheel. The ‘S’ designation indicated some additional brightwork and potentially upgraded interior trim. Optional extras included a radio, a sunroof, and upgraded seat fabrics. The Caravan body style itself was a key feature, providing a generous 450 liters (15.89 cubic feet) of cargo space with the rear seats up, expanding significantly when folded down.
Chassis & Braking
The Kadett C Caravan utilized a relatively simple chassis design. It featured a longitudinal front engine, rear-wheel drive layout. Suspension consisted of independent coil springs at the front and a live axle with leaf springs at the rear. The 1.6 S Automatic typically came equipped with disc brakes on the front wheels and drum brakes on the rear. Stabilizer bars were often included, helping to reduce body roll during cornering. The suspension was tuned for comfort, prioritizing a smooth ride over sporty handling. The relatively light curb weight of 820 kg (1807.79 lbs) helped to mitigate the effects of the modest engine power.
Market Reception & Comparison
The Kadett C Caravan 1.6 S Automatic was generally well-received as a practical and affordable family car. Critics acknowledged its spacious interior and comfortable ride, but often noted its lack of performance. Compared to other Kadett C variants, the 1.6 S Automatic offered a balance between price and features. The 1.2 models were more economical but lacked power, while the higher-spec 1.6 and 1.9 variants offered better performance but came at a higher cost. Fuel economy was reasonable for the time, averaging around 10.3 l/100 km (22.8 US mpg). Reliability was generally good, although the automatic transmission could be prone to issues if not properly maintained.
Legacy
The Opel Kadett C Caravan 1.6 S Automatic, while not a particularly groundbreaking vehicle, holds a place in automotive history as a representative of the practical and affordable family cars of the 1970s. The 16S engine, while simple, proved to be relatively durable. Today, these cars are increasingly sought after by classic car enthusiasts, particularly well-maintained examples. The automatic transmission, while not highly regarded for performance, adds to the car’s appeal for those seeking a nostalgic driving experience. Finding parts can be challenging, but a dedicated community of Opel enthusiasts helps to keep these vehicles on the road. The Kadett C Caravan remains a testament to Opel’s ability to produce reliable and versatile vehicles for the mass market.
