Here's what you need to know.
First, the good news: BMW has officially confirmed it will launch a Touring/wagon body style for the upcoming G80 generation M3. A teaser image showing the wagon's rear end was just released and now BMW is providing us with more details. Before that, however, we must inform you of the not so good news.
Road and Track has confirmed with a BMW North America spokesperson the wagon won't be sold in the US. Which was kind of expected. The current 3 Series wagon is also not available here, so it wouldn't make financial sense for BMW to bring the high-powered variant over. Of course, BMW could reconsider but for now we have to accept the reality.
That being said, BMW says the first-ever M3 wagon "is still in the early stage of approximately a two-year series development process." Like all other BMW M models, approval for prototype testing on public roads also means an "intensive testing and tuning process" at the Nurburgring.
BMW also confirmed that under the hood will lie the same powertrain that'll be used in the new BMW M3 sedan and M4 coupe and convertible: a twin-turbo six-cylinder engine with a 473 horsepower, which increases to 503 hp for the Competition spec. We still don't know whether the M3 wagon will offer a Competition version, but there's no reason why not. It all matters on whether BMW thinks there'll be enough buyers.
Another question BMW didn't answer is whether the wagon will feature rear-wheel-drive or all-wheel drive. The sedan will offer both, as the former will be aimed towards enthusiasts. It's the same deal for the six-speed manual, which will be an option in the sedan. Chances are BMW will opt for the more practical AWD and dual-clutch gearbox package only as M3 wagon buyers are more likely to be those with families and stuff to haul around.
Another reason is because of a certain rival, the Audi RS 4 Avant. It too is an overseas-only model and Americans will, unfortunately, have to watch the pair duke it out from across the pond.
