Vauxhall has given a first glimpse of the interior of its new Astra, well before the car – destined to become Britain’s top seller – goes on sale in spring next year.

Elements normally found only in the luxury sector have reached down to the Astra-size market segment, that now accounts for a quarter of all new cars sold.

One striking styling "cue" is the characteristic crease on the clearly-arranged centre console that runs from the very front of the bonnet and right through into the interior.

Further eye-catching developments in the Astra’s ample driver and passenger space include three-dimensional instruments and a 6.5 inch monitor for the information display.

An all-new infotainment system will be available stretching from a top quality audio unit with MP3 function to a digital radio with CD quality and a six-CD changer integrated into the front panel.

There are new steering wheel remote controls with buttons and turn-press wheels similar to those on a computer mouse for safe and comfortable selection of functions.

Vauxhall’s executive director of design, Briton Martin Smith says: "Astra’s interior demonstrates the importance we attach to quality appearance and ease of operation when designing the interior of our cars."
