50th Anniversary of Opel Kadett C: Car with Many Talents

• Summer of 1973: Third generation of bestselling Opel Kadett is launched
• Spoilt for choice; Opel Kadett C available as a saloon, coupé and estate with many additional variants including Aero
• Safety first: Three-point seatbelts as standard, base vehicle for the OSV 40
• Successful competitor: Sporty Opel Kadett GT/E celebrates rally accomplishments
• Compact driving pleasure today: New all-electric Opel Astra Sports Tourer Electric combines dynamic driving fun with responsibility

New Opel Astra Sports Tourer Electric celebrated its world premiere at IAA Mobility in Munich a few days ago. With its bold and pure design, modern technologies and a high level of practicality, it offers a lot of driving fun coupled with responsibility – and thus seamlessly takes the successful recipe of almost nine decades of the Opel compact class into the future. Before Opel Astra, Opel Kadett gave its name to the model series that was popular with customers for generations. One is now celebrating an anniversary: exactly 50 years ago, the third post-war generation of the compact bestseller from the brand with Blitz, Opel Kadett C, was launched for first time – and it was more diverse than almost any other model before.

1970s: Diversity is key, Opel Kadett goes around the world

A smart family car, a chic second car with a practical tailgate, or a sporty coupé – Opel  Kadett C range had many faces between 1973 and 1979. With clearly designed bodywork and a new double-wishbone front axle, rear-wheel drive Opel Kadett C made its debut in late summer 1973. Characteristic design features included a flat radiator grille, an engine hood with the brand’s signature crease, and a spoiler-shaped front apron. “Opel Kadett not only drives exceptionally well, it is also solidly built and finished. It requires little maintenance, is easy to repair and economical to run,” wrote car-test experts at “auto motor und sport”.

Customers were spoilt for choice and could find the right Kadett variant for every taste. Third Opel Kadett generation was initially available as a two- and four-door saloon in normal and luxury versions, as a three and five-door estate and as a coupé. Many more variants would follow, because Kadett C was designed as a “world car”. Not only did it roll off the assembly lines in Germany, it was also produced as a Chevette at Vauxhall in UK. In addition, it was also built in Asia, Australia and North and South America with slightly modified bodywork and technology adapted to local conditions. In Germany, efficient 1.2- litre engines with 38 kW/52 hp and 44 kW/60 hp initially provided propulsion. At the beginning of 1975, a particularly economical 1.0-litre gasoline power unit with 30 kW/40 hp joined engine range. And with 77 kW/105 hp GT/E fuel-injection model presented at IAA in 1975, Opel continued tradition of Rallye Kadett.

Safety first: First Opel Kadett with three-point belts, base vehicle for “OSV 40”

When generation C began rolling off the production line in 1973, it was first Opel Kadett to have three-point seatbelts in front seats, fixed to B pillar at top and bottom as well as at belt lock. A life-saving safety feature that, thanks to its simple one-handed operation, increased acceptance among many people who did not like seat belts. Also not to be taken for granted at the time: all buttons and switches were easy to reach, even with seatbelt fastened, and the instruments were easy to read at all times.

Biggest technical innovation of Opel Kadett C was double-wishbone front suspension with coil springs. An anti-roll bar was standard for all versions. Track width was 20 mm wider than the predecessor’s to further improve handling. Further developed rear axle harmonised perfectly, contributing to neutral handling and a high level of active safety. In event of a collision, features such as the impact-absorbing safety steering, crumple zones at front and rear and passenger compartment as safety cell minimised the risk of injury.

It was therefore no surprise that Opel Kadett C was used as base vehicle for the 1974 “OSV 40” safety vehicle. Stable longitudinal and transverse beams plus reinforced doors and sills protected the passengers in event of a collision or rollover. Vehicle was designed to withstand a frontal impact with a rigid obstacle at a speed of 65 km/h, equivalent to an impact at 40 miles an hour – hence the figure “40” in name. With this production-near prototype, Opel showed that optimum passive safety could be achieved not only with large and heavy vehicles, but also with compact, lighter cars. OSV 40 only weighed 960 kg. Experience gained from the development work and the testing of OSV 40 went into various subsequent production models.

Rallye-Kadett reloaded: Opel Kadett GT/E celebrates sporting success

Opel demonstrated that third generation Kadett was not only safe but also extremely sporty when Kadett GT/E celebrated its premiere at the 1975 IAA. Its 1.9-litre engine with Bosch L-Jetronic fuel-injection delivered 77 kW/105 hp. With a weight of around only 900 kilogrammes it could reach a top speed of 184 km/h. Its design polarised – and particularly delighted motorsport fans: Above belt line, GT/E was bright yellow, below it was black. It was not just young drivers who dreamed of GT/E back then; from 1976 onwards, well-known Opel works drivers who would soon make motorsport history took their seats in cockpit. Walter Röhrl and Rauno Aaltonen were successful with 165 kW/225 hp GT/E at Monte Carlo Rally and the Portugal Rally. Röhrl and Jochen Berger – the first professional co-driver in Germany – scored a sensational fourth place on Monte and Opel even achieved second place in overall brand classification.

Opel offered Kadett with a different kind of driving fun in 1976. With Opel Kadett Aero, the driver and passengers could let the wind blow through their hair and “cruise” around. Manufactured by Stuttgart body specialist Baur, Opel Kadett Aero was an extraordinary convertible that featured a roll bar, Targa top and a rear folding cover. Aero thus combined several cars in one: convertible, holiday car, and family vehicle as well as an all-rounder for city and commuter traffic. Nowadays it is considered a legendary classic that attracts enthusiastic attention at numerous vintage car rallies.

Opel Astra Sports Tourer Electric: Modern driving fun coupled with responsibility

Newest Astra generation also offers plenty of driving pleasure – and in a particularly responsible way. For the first time in the long success story of Opel compact class cars, Opel Astra is fully electric. With new Astra Sports Tourer Electric, which was recently presented at the IAA and can already be ordered, Opel even has one of the first battery-electric estates on the market.

Electric motor produces 115 kW/156 hp and delivers a powerful 270 Newton meters of maximum torque at the first touch of the accelerator, ensuring brisk starts and impressive acceleration. And while many other electric cars are limited to 150 km/h or 160 km/h, new Opel Astra Sports Tourer Electric has a top speed of 170 km/h. Energy for a locally emissions-free range of up to 413 kilometres according to WLTP 1 is provided by 54-kWh lithium-ion battery, – which can be recharged quickly when necessary. At same time, the electric car combines all advantages of a spacious estate with bold and pure design of current Opel Astra generation. With this pioneering combination, new Astra Sports Tourer Electric has all it takes to successfully continue Opel's long compact class history.
