Debuting at the Paris motor show in October, it will have two engines – a turbodiesel and a smaller capacity turbocharged petrol unit, as well as the five motors available from the saloon and hatchback models.
A green version, with lower emissions and fuel consumption, called the ecoFLEX Sports Tourer, will also become available.
Mark Adams, Vice-President of GM Europe Design, said it was “a stand-alone model and not simply an estate version of the saloon. All the bodywork aft of the B-pillars is unique to the Sports Tourer.
“We’ve also ensured that its design combines the sculptural artistry and technical precision found in the saloon and hatch models.”
