Astra sedan has been spied at the Nürburgring racetrack, wearing a fair amount of disguise.
The finished article will share its fascia with the upcoming Astra facelift, which will include bumper inserts above the license plate.
The interior will be subtlety updated, while the rear should mimic the Buick Verano, minus the chrome inserts above the light clusters.
Engine options remain unconfirmed, but choices will likely carryover from the standard model.
The 2013 Astra sedan could be unveiled at the Paris motor show, before going on sale across Central and Eastern Europe - the model's main markets.
