In Britain, the new Astra hatchback is available with five petrol engines ranging from an 87PS1.4-litre to a 1.6-litre turbocharged unit producing 180PS, while diesels span from 110 to 160PS in either 1.7 CDTi or 2.0 CDTi form. Prices start from £15,675.
The company said that initially, Vauxhall's Ellesmere Port plant will build the new Astra for all European markets. The UK will take the biggest share with around 25 per cent of all production headed to British buyers.
It is believed that the still under development four-door sedan version of the new Astra will come to North America as a Buick within the next two years.
