A look back at an automotive icon that revolutionized suspension

Launched in 1973 in the context of the oil crisis, the third generation of the Opel Kadett marked its time with its technical innovations and versatility. Fifty years later, we look back at the history of this iconic model that helped democratize safety and performance in the compact segment.

A diverse range to appeal to all audiences

The Opel Kadett C stood out for its variety of body styles, a bold strategy for the time. The German manufacturer offered no fewer than four versions:

The classic two- or four-door saloon appealed to customers looking for a versatile family car. With its clean lines and generous interior space, it was a sensible choice for families.

The estate, available in three and five-door versions, was aimed at customers who needed a spacious and practical vehicle. Its impressive loading capacity made it the ideal ally for craftsmen and large families.

The coupe, with its sportier design, attracted a younger, more dynamic clientele. Its flowing lines and low profile gave it a decidedly modern look for the time.

Engines suitable for all uses

The Kadett C was equipped with a range of petrol engines covering a wide range of power:

The entry-level 1.0-litre engine developed 40 hp, offering controlled consumption ideal for urban use. This frugal engine was particularly attractive to young drivers and those on a tight budget.

The 1.2-litre blocks of 53 and 60 hp formed the heart of the range. They offered a good compromise between performance and economy, perfectly suited to all-round use.

The GT/E: the accessible sports car

The flagship of the range was undoubtedly the Kadett GT/E. Launched in 1975, it embodied the sporting spirit of the brand:

Its 1.9-litre injection engine developed 105 hp, a remarkable power output for the time. Capable of reaching 184 km/h, the GT/E rivalled much more expensive sports cars.

Its low weight of around 900 kg gave it exceptional agility. Fans of sporty driving appreciated its manoeuvrability and its frank acceleration.

Its distinctive styling, including its two-tone yellow and black livery, made it a true enthusiast's car. The GT/E is highly sought after by collectors today.

Technical innovations ahead of their time

The Opel Kadett C stood out for its technological advances, particularly in terms of safety:

The double wishbone front suspension with coil springs was a real revolution. This system, usually reserved for high-end cars, offered neutral and safe road handling.

The three-point seat belts in the front seats, a first on a Kadett model, demonstrated Opel's commitment to passive safety. Their ease of use helped to make seat belt use more widespread.

Energy-absorbing steering and programmed crumple zones significantly improved occupant protection in the event of a collision.

A commercial and sporting success

The Kadett C enjoyed undeniable commercial success:

Produced from 1973 to 1979, it sold more than 1.7 million units. This impressive figure is a testament to the public's enthusiasm for this versatile model.

Its production extended well beyond German borders. Assembled in the United Kingdom under the Vauxhall brand, it was also produced in Asia, Australia and the Americas.

On the sporting scene, the Kadett GT/E shone in rallying:

Entered in the World Rally Championship, it allowed Opel to take second place in the constructors' standings. Drivers Walter Rรถhrl and Rauno Aaltonen distinguished themselves in particular at the wheel of a 225 hp version during the Monte Carlo and Portugal rallies.

A lasting legacy

The Opel Kadett C has left a lasting mark on automotive history:

Its innovative approach to safety inspired many manufacturers. The OSV 40 prototype, based on the Kadett C, demonstrated that a high level of passive safety was possible on a compact and lightweight vehicle.

Its versatility and road qualities have helped to build loyalty among a generation of drivers to the Opel brand. The Kadett has thus become a true symbol of reliability and accessibility.

Its commercial success allowed Opel to establish itself as a major player in the compact segment in Europe. The Kadett thus paved the way for its successors, notably the Astra which continues this legacy today.

Fifty years after its launch, the Kadett C remains etched in the collective memory of car enthusiasts. Its blend of practicality, performance and innovation makes it a fascinating witness to the evolution of the automotive industry over the last few decades.
