Corsas powered by the 1.3 CDTi engine were particularly unpopular with retail buyers, who account for the majority of the hatchback’s customers. In 2017, just 0.5% of Corsa retail purchases were of the diesel.
A spokesman told Autocar that this low demand made the diesel Corsa too costly to retain amid the British brand’s ongoing efficiency-boosting measures. Vauxhall's new parent company, the PSA Group, is rolling out several measures to boost its profitability.
This is also the explanation given for Vauxhall’s decision to streamline the Corsa's trim levels. The Ford Fiesta rival had been offered with 11 trims, but this now has been cut to seven: Active, Design, Energy, Sport, SRi Nav, SE Nav and SRi VX-Line Nav Black.
