A rare "Sport" model was produced in 1985 to homologate for the sub 1,300 cc class of Group A for the British Rally Championship. These sport models were white and came with unique vinyl decals, a 13SB engine with twin Weber 40 DCOE carburettors, an optional bespoke camshaft, a replacement rear silencer, and few luxuries. This gave 93 hp and a top speed of 112 mph (180 km/h) with a 0–60 mph time of 8.9 seconds. These are by far the rarest models (500 produced) and thus acquire a high market price if one does become available.
In November 2010, a facelift was announced. A revised front end was the most dramatic difference over its predecessor, consisting of a new grille, a restyled front bumper and new 'Eagle Eye' headlamps (introduced on the Insignia) which contain daytime running lamps, standard across the refreshed Corsa range. (Vauxhall versions gained the latest badge from 2008 on the front grille, tailgate and steering wheel). A new 'Touch and Connect' multimedia system from Bosch was made available as an option on certain Corsas, replacing the CD60 unit. Alloy wheels are upgraded on SXI, SE and OPC/VXR versions. Production ended in the end of 2014, with the Adam styled Corsa E released.
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).
