The Kadett featured a more modern design than the Volkswagen Beetle that then dominated the market for small family cars in West Germany and various surrounding countries. The Kadett offered more passenger space, more luggage capacity, and better visibility for the driver. Its water-cooled engine provided effective heating for the passenger compartment. However, by the mid-1970s the Kadett's weakness was already apparent as the car's bodywork was not well protected from corrosion.
Alfred P. Sloan, Jr., and Charles Erwin Wilson ("Engine Charlie" Wilson), GM's president, were considering the options. Later in April, Sloan sought to resolve the differences of opinion with a position paper that he hoped would set up conditions for resuming control of Opel that would put at rest the doubts of GM's more conservative financial minds.
The 75 PS (55 kW) 1.3 CDTI engine was updated in the middle of 2007 to bring CO2 levels to just 119 g/km, meaning that twelve months' Vehicle Excise Duty in the United Kingdom costs £30 and is eligible for the Plan 2000E (a rebate of €2000 in the purchase of a new car) in Spain.[41] The car is also used as the villain car in Lights, Motors, Action! Extreme Stunt Show at Disney's Hollywood Studios.
Other special jobs were undertaken at the Rüsselsheim factory. One that was too exotic to be typical was the construction of an intercooler for the supercharger of the famous Junkers Jumo aircraft engine. Special methods had to be developed to fabricate this vital assembly from very thin sheets of aluminium. With work like this going on, Germany's enemies naturally took note of the various Opel plants, and starting in August 1944, began attacking them by air. Destruction was heavy at both Rüsselsheim and Brandenburg from the attacks by Allied bombers. Never was the outlook bleaker at Adam Opel AG than in the first months of 1945.
The Kadett C was introduced in Brazil as the Chevrolet Chevette. The three-door station wagon was called the Chevrolet Marajó, and a pick-up was named Chevy 500. Brazilian production commenced in 1973, with the Marajó being added in 1980 and the Chevy 500 in 1983, shortly after a significant facelift affected the entire line. Brazilian cars had engines in various combinations of size - 1.0 (1992-1993), 1.4 (1973-1982), or 1.6 (1982-1995) liters - and fuels (gasoline or ethanol), though not all combinations were available for all body configurations. The last Marajó was built in 1989, the last Chevette in 1993, and the last Chevy 500 in 1995.[27]
The suspension and brakes got some serious attention too, and the Rally 1900 was quite the sensation in its brief heyday, and garnered a very positive review by Car and Driver. (see related story on C/D’s Opel Kadett assassination story). Until the Ascona/Opel 1900 (CC here) came along in about 1971, the Rally carried a bright flame for Opel. The Ascona had been planned as a replacement for the Kadett, but when Ford launched their very bare-bones Escort, Opel kept the Kadett on, although at least in the US, it reverted to a very basic trim level and only with the 1100 cc motor, and sales swooned, due to rising prices as a result of the falling dollar.

In 2007, Opel introduced sport version of Corsa tuned by Opel Performance Center (OPC) – Corsa OPC. Corsa have 1.6 litre I4 turbo engine with 141 kW (192 PS; 189 hp) at 5.850 rpm and 230 N⋅m (170 lb⋅ft) of torque at 1,980 to 5,850 rpm, with overboost function which boost up torque figure to 266 N⋅m (196 lb⋅ft). 0 to 100 km/h (62 mph) time is 7.2 s and top speed is 225 km/h (140 mph). Differences with standard Corsa in interior are sporty Recaro seats, OPC steering wheel and gear knob, instrument dials with OPC background.
The saloon and estate car versions were produced in China by Shanghai GM as Buick Sail and Buick Sail S-RV, respectively from June 2001 to February 2005. That year, they received a facelift and became known as the Chevrolet Sail and SRV. In September 2006, Chile became the first country outside China to receive the Chinese assembled Sail; it is called the Chevrolet Corsa Plus there, available as a four door saloon with a 1.6 L 92 PS (68 kW) engine. The Corsa Plus includes dual front airbags, anti lock brakes, air conditioning, electric windows and central locking as standard equipment.
Rüsselsheim/Geneva. Opel is paving the way to the future by providing even more information, services and safety in cars. The Rüsselsheim-based carmaker is presenting the personal mobility services offered by Opel OnStar – after already announcing the intention to bring Opel OnStar to Europe last year – at the International Motor Show in Geneva (Hall 2, Stand number 2231) ...
The next step for Opel was the resumption of passenger car production. It might have seemed easiest to bring back the Kapitän first since its engine was already in production for the truck, but occupation regulations restricted German civilians to cars of 1.5 L or less, which made the Olympia the obvious candidate. Under Dr Ing e.h. Karl Stief, who had been chief engineer at Opel since 1934, useful changes were made to this tough little car. The Dubonnet front suspension was replaced by a conventional coil-and-wishbone layout and the steering was correspondingly rearranged.
The Calibra, styled by the American head of GM design Europe, Wayne Cherry (retired), is considered by some the most stylish Vauxhall/Opel ever, but being based on the Vectra chassis its ride and handling were not significantly better than that of the family car from which it grew. It was, however, the most aerodynamically efficient Opel everwith a drag coefficient (Cd) of 0.26. It remained the most aerodynamic mass production car for the next 10 years, until the Honda Insight was launched in 1999 with a Cd of 0.25.
