A launch looks likely in the near future, and the updated hatch seems as though it won't be a dramatic departure from today's car.

The updated Opel Astra has been spied undergoing testing Germany, wearing a face that's remarkably similar to that of the current car.

This latest prototype sports camouflage only on its front fascia and around the tail-lights, indicating the facelift isn't too far from being officially revealed.

Up front, the refreshed Astra sports new headlight graphics, a restyled grille, and a new bumper. The changes here will likely bring the small hatch a little closer visually to the GT X Experimental concept, which is said to preview the brand's new design language.

At the rear, the prototype has a new set of tail-lights that seem almost identical to the current car's. Look carefully, though, and you'll notice the fog light and reversing light segments are larger.

As visual differentiation between the current Holden Astra and its European siblings is limited to the badges used, it's highly likely all of changes seen here will flow through to Australia-bound models.

Our spy photography agency also managed to capture a shot of the revised Astra's interior. While there may be trim and equipment upgrades in the offing, the cabin seems to be carried over with no major changes.

There's been some talk the Astra facelift could swap out GM engines for PSA Group units, but it's also very probable the engineering costs for such a move are prohibitive.

If so, we'll have to wait until the next generation arrives before we see an Astra with designed-in-France engines.
