The sporty Corsa, which is available to order now and due in showrooms in September, has a 10bhp advantage, using the same 1.4-litre turbocharged petrol engine as the Corsa White and Black Editions to offer 148bhp and 162lb ft of torque.
Like the models with which it shares its engine, the Corsa GSi reaches 62mph in 8.9sec, making it a tenth quicker to the mark than the Fiesta ST-Line. Top speed is 128mph — 3mph up on its rival.
Following the recently launched Insignia GSi, which revived the classic GSi name, the new Corsa borrows key chassis hardware and geometry from the Corsa VXR, the car it will indirectly replace.
The set-up incorporates the VXR variant’s firmer springs, dampers and uprated brakes. There are also lightweight 18in wheels on 215/40/R18 tyres available as part of the GSi Plus Pack, which costs £1900 and also brings Recaro sports seats and bi-xenon headlights with cornering lights.
