Audi's upcoming A6 E-Tron has been spotted testing again as a wagon, or Avant as the automaker likes to call the practical body style.

The A6 E-Tron is a midsize electric vehicle previewed by a concept of the same name at the 2021 Shanghai auto show. The concept showed the vehicle in its standard sedan (or possibly hatchback) body style.

Audi followed up the original concept last year with the A6 Avant E-Tron concept previewing the wagon body style for the A6 E-Tron.

The sedan is expected to debut early next year as a 2025 model. The wagon should follow roughly 6-12 months later. Both are a year late due to software development issues plaguing a number of EVs at the Volkswagen Group, including Audi's Q6 E-Tron that is on track for a debut shortly as well. A related Porsche Macan EV will also debut soon.

As the spy shots indicate, the A6 Avant E-Tron will closely resemble the concept version. There will be some differences for production, such as the taller ground clearance. The LED light bar that formed the taillights of the concept is expected to remain, though with a more conservative design. Also remaining are the cameras replacing the conventional side mirrors, though this feature may not be offered in the U.S. due to local regulations.

Both the Q6 E-Tron and A6 E-Tron will be among the first vehicles based on VW Group's PPE dedicated EV platform designed for high-volume luxury models.

Audi has confirmed the A6 E-Tron will offer single-motor rear-wheel-drive and dual-motor all-wheel-drive powertrains. Audi used a dual-motor setup in the concept with a 469-hp rating. Audi also said the concept was fitted with a 100-kwh battery good for more than 300 miles of range and capable of charging from 5-80% in less than 25 minutes thanks to 800-volt technology.

A sporty S6 E-Tron is also out testing and Audi Sport may also offer a high-performance RS 6 E-Tron at some point.
