A prototype for a new Audi A7 Avant wagon has been spied again, revealing many new details.

The vehicle will be twinned with a redesigned A7 Sportback hatchback in an expanded A7 family due to start arriving around 2025. It isn't clear if the wagon will reach the U.S., but the hatch will likely make it to these shores as a 2026 model. The current A7 Sportback has been on sale since the 2019 model year and is due for a redesign soon.

This A7 Avant will replace the current A6 Avant that for its next generation is going the electric route. Prototypes for an electric A6 Avant E-Tron as well as an A6 E-Tron sedan have already been spotted testing, and a debut for both should be just around the corner.

A similar strategy is planned for the A5 family, which is about to spawn a redesigned A5 Sportback, as well as a new A5 Avant replacing the current A4 Avant. Expect any future A4 Avant (and A4 sedan) to run on batteries. It's all due to a naming shift announced by Audi last year, in which electric models will feature an even number in their names and names for models with an internal-combustion engine will carry an odd number.

Audi hasn't mentioned plans for the next A7, but expect the automaker to use an updated version of the MLB platform, known as the PPC (Premium Platform Combustion). Audi plans to phase out combustion models in most markets later this decade and is therefore unlikely to invest in a new ICE platform for the next A7.

The prototype for the A7 Avant shows a sportier, more sculpted design than the current A6 Avant, which makes sense if the vehicle is to be twinned with a future A7 Sportback. A large, protruding grille sits up front, while at the rear are wide, muscular hips that integrate side vents below the taillights. Interestingly, it looks like Audi also plans a return to exposed exhaust tips, though only on one side of the rear fascia in some grades.

Yellow warning stickers on the prototypes points to an electrified powertrain being tested, likely a plug-in hybrid setup.

A high-performance RS 7 Avant should also be in the works, also with a plug-in hybrid powertrain. It will replace the current RS 6 Avant that Audi will send out with the recently revealed 2025 RS 6 Avant GT model.
