Much as we're loathe to admit it, Audi has done some good work proving that high performance wagons a fun niche that automakers can get into. And it seems that BMW has been listening.

Taking to Instagram, BMW's M division posted a picture of a wagon's rear end with the following captions: TheM3, BMW, M3, TOURING, and BMWM. Now, we may not be fancy, big-city private investigators, but we know a clue when we see one.

Naturally, we're pretty excited. Presuming, as seems safe, that it will share its underpinnings with the rest of the M3/M4 line, it will get the S58 twin-turbo 3.0-liter I6 making 500-odd hp and offered with a manual transmission. Take that, RS6 stans.

According to Road & Track, BMW plans to start testing prototypes at the Nurburgring in the next few days, which will kick off two years of development. Sadly, that means there will be quite a wait.
But we'll be here. Waiting.
