With the current Audi A4 now entering its seventh year in showrooms, a replacement for the luxury automaker's staple midsized sedan and wagon is just around the corner.
Expected to draw some styling elements from the recently-launched Audi TT, the next-gen A4's exterior will nevertheless be a subtle renewal of the current model's styling.
Changes will include a slight reshaping of the headlights, bumpers and sheetmetal, but Audi's familiar hexagonal grille will continue to dominate - and if the Prologue Concept is anything to go by, will only get bigger in successive generations.
The grille, however, will no longer overlap the leading edge of the bonnet as it does in the current A4. Instead, expect a similar treatment to that of the new TT.
Overhangs also appear to be slightly shorter than before, and the wing mirror mountings have also been moved down to improve driver vision.
Underneath all the bodywork will be Audi's new MLB-Evo platform, which takes the current A4's architecture and replaces many steel components with lighter aluminium structures.
Weight savings of 100kg from the new body-in-white are predicted, but what impact this has on the A4's overall weight has yet to be seen.
The new A4's interior remains under wraps, but a more modern design that borrows heavily from the TT's spectacular cockpit is expected to feature.
