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.

the Chevy Chevette, while a MUCH better car than the Vega was at the time, and even now, that’s not saying a whole lot, other than it WAS infinitely more durable and longer lasting and reliable than the Vega, though by ’76, the Vega was decent enough, but the damage was done. I know as my Mom drove a ’76 Vega from roughly 78-83 with the only major thing being the carb being rebuilt around 1980. The Chevette was basically a redesigned Kadett/Vauxhaul Chevette.
The Corsa GSi family was founded in 1988 by the 100 hp Corsa A (now a much sought-after classic) Then came the Corsa B GSi 16V with 109 hp and a powerful low-end torque characteristic, the Corsa C GSi with 125 hp and a top speed of 202 km/h, and from 2007 the Corsa D GSi, for the first time with turbocharging and 150 hp from 1,600 cubic centimetres. In August 2012 Opel and the Corsa took a break from the GSi – until September 2017. At the Frankfurt Motor Show (IAA), the Opel Insignia GSi celebrated its world premiere and the GSi label its comeback. And now, one year later, the Corsa GSi has returned too.

It will all be possible by switching to a brand new platform belonging to parent company PSA, a “multi-energy platform” as billed by Opel which has already served as foundation for the aforementioned Peugeot 208. Much like the French supermini has spawned an electric version, the new Corsa will also be offered in a zero-emissions guise dubbed “eCorsa.”
