The high performance of the new Corsa GSi is complemented by the athletic exterior looks featuring large air intakes, sculptured bonnet, prominent rear spoiler and precisely modelled side sills. From the front, the bold Opel GSi fascia with large honeycomb grille and the central Opel Blitz supported by two wings, along with the exterior rear view mirror housings in carbon racing-look become visible. The large chrome-ringed design elements that are visually connected in a horizontal line via black crosspieces running across the front, along with the black traverse cleat on the bonnet support the impression of sportiness. The vibrant styling is also present when viewed from the rear. The prominent spoiler on the edge of the roof creates additional downforce, the sporty chrome tailpipe is framed by the vibrant design of the rear apron in body colour.
Strangely, the joint-venture was announced several years ago. Then, just as the Crossland X and C3 Aircross hit showrooms, PSA decided to buy GM Europe – the company that owns Vauxhall. So this pair are a preview of a future strategy in which all Vauxhalls, Peugeots, Citroens and DSs will draw from shared engineering, like the VW Group’s brands have done for years.
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).
