Opel (Vauxhall in the UK) has chosen to reveal pictures of its new subcompact hatch in all its glory, ahead of its scheduled world premiere at the Frankfurt Motor Show in September. Clearly influenced by the new Insignia, the sixth generation Astra hatch is based on GM’s new Delta platform, that also underpins the Chevy Volt and Cruze models. The new Astra also comes with a new set of engines including 1.4-litre and 1.6-litre turbocharged petrol units.
