Although it's covered in plenty of shrouding and tape, the interior of the next-generation Astra will feature a clearly delineated two-tier dashboard, with controls for the entertainment and navigation systems on the top level, while the climate control buttons and knobs reside on the lower level.
Like every new car coming out of GM, the new Astra looks like it will feature the company's MyLink touchscreen entertainment system, which can utilise selected smartphone apps, like Spotify and Stitcher.
At first glance, the new Astra seems to have arrested the current car's descent into button layout madness.
Externally, the 2015 Astra which our spies spotted doing the rounds at the Nurburgring doesn't look that different to the prototypes we spotted back in April.
The shape of the headlights isn't a world away from the current car's, but the next-gen Astra will feature a deeper grille that's heavily influenced by last year's Opel Monza concept car.
At the rear, the latest prototypes are still plying the streets with temporary taillight units embedded within a plastic facade.
Although it's not possible to discern the final shape and design, the in-board positioning of the reversing and fog lights, and the width-wise arrangement of the temporary lights suggests a thin, narrow design not too dissimilar to the one seen on — you guessed it — the Monza concept.
The next-generation Astra rides on a modified version of the Delta II platform that underpins the current model. Sources indicate that the car will grow about 60mm in length to just shy of 4.5 metres.
Motivation is expected to come from a range of turbocharged three- and four-cylinder motors, with some variants sporting a dual-clutch transmission in place of a traditional automatic shifter.
The new Astra will make its public debut next year and we believe that it will wear Holden lion badges not too long after that.
