The Opel Kadett B Coupe 1.9 S, produced between 1965 and 1973, represented a sporting evolution within the broader Kadett B range. Positioned as the performance variant of the coupe body style, the 1.9 S aimed to offer enthusiasts a more engaging driving experience than the standard Kadett models. It was a key part of Opel’s strategy to appeal to a younger demographic in post-war Europe, offering a blend of affordability, practicality, and a degree of style. The Kadett B itself was a significant model for Opel, representing a move towards more modern design and engineering, and the Coupe 1.9 S was the flagship of that generation.

Powertrain & Engine Architecture
The heart of the Kadett B Coupe 1.9 S was the 19S engine, a 1,897 cc (115.76 cubic inches) inline-four cylinder unit. This engine was a development of Opel’s CIH (Cylinder Head Inclined) engine family, known for its robust construction and relatively simple maintenance. The ‘S’ designation indicated a higher state of tune compared to the standard 1.7-liter engine found in other Kadett B models. Fuel delivery was handled by a Solex carburetor, a common setup for the era. The engine featured a two-valve per cylinder configuration and a compression ratio of 8.8:1. The longitudinal engine placement and rear-wheel drive layout were typical for European cars of this period, offering a balanced driving experience. The four-speed manual transmission was standard, providing direct control over the engine’s power.
Driving Characteristics
The 1.9 S offered a noticeable performance improvement over the base Kadett B models. With 103 horsepower, it could achieve a top speed of approximately 99 mph (160 km/h). While not a sports car by modern standards, it provided brisk acceleration and a willing character. The four-speed manual gearbox allowed drivers to keep the engine in its optimal power band. The rear-wheel drive configuration contributed to a balanced feel, although handling was limited by the relatively simple suspension setup and narrow tires of the time. Compared to the standard Kadett, the 1.9 S felt more responsive and capable, making it a popular choice for those seeking a more engaging driving experience. The gearing was relatively tall, prioritizing fuel economy at cruising speeds, but required downshifts for quicker acceleration.
Equipment & Trim Levels
The Kadett B Coupe 1.9 S was generally well-equipped for its time, though options were available to further enhance the interior. Standard features included comfortable cloth upholstery, a basic instrument cluster, and a steering wheel. The interior was functional and relatively spacious for a coupe. Optional extras included a radio, upgraded interior trim, and a sunroof. The 1.9 S often featured a more sporty interior trim than the base models, with unique seat patterns and dashboard accents. Exterior features included chrome trim, distinctive badging, and often, a two-tone paint scheme.
Chassis & Braking
The Kadett B Coupe utilized a body-on-frame construction, which was common for the era. The front suspension consisted of double wishbones with a transverse stabilizer, while the rear suspension employed a trailing arm setup with a transverse stabilizer. This suspension configuration provided a reasonable level of comfort and handling, although it wasn’t particularly sophisticated. Braking was accomplished via disc brakes at the front and drum brakes at the rear. The braking system was adequate for the car’s performance, but lacked the stopping power of more modern systems. Steering was via a rack and pinion system, providing precise and responsive control.
Market Reception & Comparison
The Kadett B Coupe 1.9 S was generally well-received by automotive critics and buyers alike. It was praised for its sporty styling, improved performance, and relatively affordable price. Compared to other coupes in its class, such as the Ford Capri, the Kadett offered a more practical and economical option. The 1.9 S was often seen as a more sensible alternative to the more expensive and less fuel-efficient sports cars of the time. Reliability was generally good, although maintenance was required to keep the carbureted engine running smoothly. Fuel economy was reasonable for the period, but not exceptional.
Legacy
The Opel Kadett B Coupe 1.9 S holds a significant place in automotive history as a representative of the affordable, sporty coupes of the 1960s and early 1970s. The 19S engine proved to be a durable and reliable unit, and many examples are still on the road today. In the used car market, well-maintained Kadett B Coupe 1.9 S models are sought after by collectors and enthusiasts. The car’s simple mechanical design makes it relatively easy to maintain and repair, and its classic styling continues to appeal to a wide range of drivers. The Kadett B Coupe 1.9 S remains a testament to Opel’s ability to create stylish, practical, and enjoyable automobiles.
