A new hot hatch version of the Opel Astra may be in development, potentially powered by a 160 hp twin-turbo diesel engine, although some reports suggest a smaller 1.6-liter turbo engine could be used instead. The Vauxhall Astra, which is related to the Opel Astra, is expected to get a bi-turbo diesel warm hatch variant. Details about the new Opel Astra model are not yet clear, with various reports discussing different aspects of the Opel brand and its vehicles.
