While little is known about the new X3 M, we can glean a few things from the video. Based on the exhaust note, it sounds like it will pack a turbocharged inline-six under the hood, likely an updated version of the 3.0-liter 444 horsepower unit from the M3 and M4. Power will likely be sent to all four wheels through a seven-speed DCT. Expect 0-60 mph times to be around 4 seconds, possibly lower with the rumored competition package.
Visually, the X3 M gets the usual M treatment. Look for revised front and rear bumpers, new bodywork along the side, new mirror caps and those quad exhaust tips. This is the closest thing we're likely to see to an M3 wagon here in the U.S. Look for a full debut sometime later this year.
