Spy shots of the 2024 Audi A6: slight changes for a mid-cycle refresh.

Though it doesn't get much attention, Audi's A6 is one of the most handsome models in the midsize sedan segment.

That A6 is now about to get an update, and fortunately, it looks like designers won't be tinkering with the car's styling.

The current A6 was introduced in 2018 as a 2019 model. An updated version is expected to be unveiled later this year or early next year, perhaps as a 2024 model (the 2023 Audi S6 has already been announced). The arrival of the updated A6 should precede the arrival of the new A6 E-Tron, which Audi previewed in concept form at the 2021 Shanghai Motor Show. The electric A6 is slated for 2023 and will likely appear as a 2024 model.

The latest spy shots show a prototype of an updated version of the regular A6, with testers seeing new inside lights at both ends, as well as new mesh patterns on the grille and front intakes. The rear fascia also features a new design.

Similar tweaks should feature on updated versions of other members of the A6 family, including the Avant and allroad wagon, the S6 and RS 6 performance duo.

It is not clear what updates Audi plans for the A6's cabin and powertrain. An updated infotainment system and some powertrain performance improvements are both likely. The U.S. may also finally see the introduction of a plug-in hybrid option for the A6 that is offered overseas.

Currently, the base powertrain in the U.S. is a 2.0-liter turbo inline-4 with 248 hp. Above that is a 3.0-liter V-6 turbo with 335 hp. Further above that is the S6 with a turbocharged 2.9-liter V-6 with 444 hp, and at the top of the range is the Avant wagon-only RS 6 with a turbocharged 4.0-liter V-8 with 591 hp. Interestingly, we hear that the upcoming A6 E-Tron will also get its own performance flagship, the RS 6 E-Tron.

The A6's plug-in hybrid option, available only overseas as noted, combines a 2.0-liter turbo four with an electric motor for a total of 367 hp.

Updates will be released as development progresses.
