Updated four-door coupe spotted with slightly less camouflage, ahead of an anticipated debut before the end of the year.

The facelifted Audi A5 Sportback has been snapped by photographers once again, this time during hot weather testing in Europe.

It's believed this particular prototype is wearing the popular S line exterior sports package, which gets a more aggressive body kit than standard.

We can still see plenty of swirly camouflage concealing the finer details of the revised bumpers, though it's clear the mid-life refresh for the A5 range will be much like the related A4, with subtle changes to the bumpers, grille, and headlights. Expect new LED graphics front and rear, too, along with new alloy wheel designs.

We haven't got images of the interior yet, but the A5 should get similar upgrades to the A4 sedan and Avant wagon, scoring a larger 10.1-inch MMI infotainment system with new touchscreen functionality and the Volkswagen Group's new MIB3 infotainment software – which should allow for wireless Apple CarPlay integration.

The addition of touch response on the screen will remove the MMI Touch rotary dial and touch pad on the centre console as well, meaning there will be more space for cupholders and cubbies.

Other changes should include new interior trims and insert options, along with the availability of Audi's latest semi-autonomous driving systems.

The revised A5 line-up is expected to make its debut before the end of the year, potentially around the same time as the Frankfurt motor show in September.
