A facelifted Audi A4 Avant has been spied undergoing winter testing in Sweden.
This is the second update to the current-generation A4, and appears more substantial than the revision due to go on sale in Australia from early 2019.
While that update has subtly new front and rear bumpers, and a more 3D effect for the grille, this prototype sports a more extensive overhaul.
It's immediately apparent this car features a wider, flatter grille, like the one used on the latest A7. There's also a new set of headlights, which lose the current model's lightning bolt inner section.
Out the back there's a new rear bumper with a more aggressive cut-out surrounding the exhaust tips and reflective markers. While the tail-lights are unchanged on this development model, we expect to see revisions here before too long.
Given the current update for the A4 was only revealed in the middle of this year, it's likely this more extensive facelift won't surface until the latter half of 2019.
