Around about this time next year, Opel will officially launch its new Astra at the Frankfurt Motor Show. However, you can expect a big build-up, as the company has already started its marketing campaign with a series of teasers designed to stir up interest. We know that the new Astra will have an all-new chassis and low emission engines. It is expected to continue the sporty design theme of the new Insignia. Apart from that the company wants to keep you guessing, having only released part of a design sketch and a covered picture of the new model, taking its place among some of the important Vauxhall Opel models that have graced the important C segment in the past.
