Photographers have snapped the next-generation Audi A3 sedan during development testing, shortly after we received images of the sportier S3 variant.

Like the new Audi Sport model photographed earlier this week, the new three-box A3 will don an evolutionary design, keeping the overall shape and size of the current model blended with Audi’s latest design cues plucked from other vehicles in the stable.

The front is more aggressive and angular, with a lower and wider stance and sharper lines for the front grille, headlights and bumper elements.

Similar changes have been made at the rear, with slimmer tail-lights with sharper corners, and going by the S3 seen earlier this week they’ll incorporate new LED signature graphics.

More significant changes will be made in the cabin and under the skin. Inside, the new A3 will score Audi’s latest MMI system with touchscreens up to 10.3 inches, likely incorporating the Volkswagen Group’s new MIB3 infotainment architecture which allows for wireless Apple CarPlay.

The Virtual Cockpit digital instrument cluster will get an update, and there should be new trims and textures used throughout the cabin to move the A3 further upmarket.

Mechanical changes should include an updated version of the MQB architecture, unofficially dubbed 'MQB Evo’, which not only allows for increased dimensions and interior space, but also compatibility with new 48V mild-hybrid powertrains and an updated plug-in hybrid offering.

It’s believed the new-generation Audi A3 isn’t far from making its production debut, potentially at or around the Frankfurt motor show in September.

Given the current wait times for new Audi models, we’d wager Australian deliveries won’t start until very late in 2020 or early in 2021, shortly after the related eighth-generation Volkswagen Golf and around the same time as the also related next-gen Skoda Octavia.
