The Corsa now has the styling first seen in the Insignia and Astra. There's a new front grille, bumper and headlight design that includes daytime running lights.
There are five new exterior colours, plus new colours and finishes for the interior, too.
Vauxhall says there have also been changes to the Corsa's steering and suspension set-ups.
First deliveries of the new Corsa are expected in February, with prices rising by £60-£75 depending on the version.
