The two brands' first fully electric car is expected to be their top seller as they step up their electrification plans under new owner PSA Group.
The regular Corsa will enter production in the Zaragoza plant in Spain, according to Vauxhall and Opel, with the electric variant following closely behind.
The electric Corsa is part of Vauxhall and Opel’s wider electrification strategy, under which every model will be electrified in some way by 2024. A plug-in hybrid Grandland X is also planned.
The next Corsa will likely be built on the same architecture as the next Peugeot 208 and Citroën C3. A product planning slide that surfaced last year showed PSA’s intention to produce an all-electric 208 as its next zero-emissions model (its first being the Ion).
PSA aims to have Vauxhall and Opel back in profit by 2020; the brands posted losses of £190 million in the second quarter of 2017. The Zaragoza plant has built Corsas since 1982 and also currently produces the Mokka X, Crossland X and Citroën C3 Aircross.
No details have been given about ranges, but that of rivals such as the Renault Zoe, Nissan Leaf and Hyundai Kona Electric - at 250 miles, 235 miles and 292 miles respectively - should put the electric Corsa and 208’s ranges comfortably above 200 miles.
The Corsa was previously Vauxhall’s top seller in the UK, but has slipped in recent months to eighth place. It has been outsold heavily so far in 2018 by the newer Mokka X (2587 Corsas versus 3767 Mokkas) and sales were down 30% across 2017. The Corsa has been on sale in the UK in its current form since 2014.
Vauxhall had a tough 2017, with market share shrinking to 7.61% last year compared with 9.32% in 2016.
