Intelligent lightweight design begins on the computer, using the newest virtual development methods. The specific use of various steel grades and connection methods enabled the Corsa’s big weight reduction. This includes the consistent use of high-strength and ultra-high-strength steels, as well as the optimization of load paths, connections, structure and form. Compared with the previous model, the body-in-white is 40kg lighter. The next Corsa is based on the multi-energy platform for small and compact cars, which allows a variety of propulsion systems. Customers can choose from combustion engines or the all-electric version.

Later, an 1800 cc version wis introduced for the Kadett/Astra GTE model. This range o ingines wis an aa uised for later models o the Corsa/Nova, an the mid-sized Cavalier/Ascona. The Kadett D wis an' a' equipped wi a 1600 cc diesel ingine that wis possible tae drive as cheap as 5.0 L/100 km, an a cairy-ower 1196cc OHV ingine. It wis an aa produced as IDA Kadett in Kikinda, Yugoslavie.
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).[8]
