Opel also produced the first mass-production vehicle in Germany with a self-supporting ("unibody") all-steel body, closely following the 1934 Citroën Traction Avant. This was one of the most important innovations in automotive history. They called the car, launched in 1935, the Olympia. With its small weight and aerodynamics came an improvement in both performance and fuel consumption. Opel received a patent on this technology.
The GSi's engine mapping had been carried out by Opel tuning specialists Irmscher. A model with the 82 PS (60 kW) 1.4 L multi point fuel injected engine, which was otherwise mechanically identical to the GSi, also became available as the Nova SRi in the United Kingdom. In January 1988, a turbocharged version of the Isuzu diesel engine was introduced, with power increased to 67 PS (49 kW).
