UPDATE, 31 August: BMW M has provided the clearest images yet of the M3 Touring, with a video posted to Facebook showing the wagon in camouflage (see below).
The car appears to share a similar grille to the polarising 2021 4 Series Coupé, despite this feature being omitted in early renders.
UPDATE, 13 August: BMW M boss Markus Flasch has confirmed the division is developing an M3 Touring. A shadowy picture shown on his personal Instagram account revealed the prototype M3 wagon, along with the hashtag 'erlkönig' – a label typically reserved for camouflaged prototype models.
A spokesperson for BMW Australia has told CarAdvice: "We plan to introduce the M3 Touring and will advise arrival timing closer to the launch date".
No official details have been shared at this point, but with the release of the M3 Touring expected in 2023, the new performance wagon may align with the anticipated facelift of the current 3 Series range.
BMW's M division may be developing a wagon variant of the upcoming 2021 M3 performance sedan.
According to a report from BMW Blog, a "trusted source" confirmed the performance wagon – to be known as the M3 Touring – has been given the green light for a 2023 launch.
The above render from @zer.o.wt provides a convincing look at what we can expect if the rumours prove to be true.
This would be the first M3 wagon to make it to production, despite the German car manufacturer playing with the idea of an E46 M3 Touring back in the day.
An E46 M3 Touring prototype was developed for testing, but the project was discontinued.
The 2021 BMW M3 sedan and M4 Coupe is expected to be announced in the coming weeks.
