It’s more powerful than the M3 Competition Package.
For reasons unknown to us, BMW refuses to build a wagon version of the M3 despite offering the 3 Series Sports Wagon. Sure, there was the E46 M3 Touring, but that was a one-off that never entered mass production. In the US, the 330i XDrive is available with a 2.0-liter gasoline engine developing 248 hp and 258 lb-ft, as well as a 180 hp, 280 lb-ft diesel variant. In Europe, there's also a range-topping 340i, but that clearly wasn't enough for this owner who has effectively created the full fat M3 wagon BMW refuses to build.
The project started life as an unassuming diesel-powered 3 Series Touring but now it packs an M3 S55 engine under the hood. The owner also fitted a stage two tuning kit extracting 530 horses from the biturbo inline-six 3.0-liter engine, making it significantly more powerful than the standard M3. It's even more powerful than the M3 Competition Package and the 460-hp M3 CS Limited Edition.
In addition, the owner fitted the super wagon with the M4 GTS' hood and steering wheel, along with an M Performance exhaust and the M3's Competition package. You can see the wild wagon in action in a video recorded at the 2018 Bimmerfest in the Netherlands. It looks and sounds sublime and makes us wish BMW would make an official M3 wagon. We'll have to wait and see what the next-generation M3 lineup brings. Until then, this probably won't be the last custom-built BMW M3 wagon we'll see.
