Report: BMW X3 M getting ready to rumble

According to the wizards at Europe's CAR magazine, sources within BMW have confirmed that the high-performance X3 M could launch as early as 2012. A stupid-fast X3 hardly seems necessary, but then again, that's what we said about the larger X5 M and X6 M before falling in love after our stints behind the wheel.CAR states that the X3 M will likely be powered by a tweaked version of the new six-cylinder engine bound for duty in the M3. In the X3, this engine will reportedly produce somewhere around 450 horsepower, and could use a brand new tri-turbo system – one electric turbocharger paired with two exhaust-gas-driven units.A 450-horsepower X3? With three turbochargers (one of which is electric)? Sounds absurd (and is to be taken with a grain of salt... for now), but based on our experiences with the rest of BMW's M range, consider us totally stoked. -AB
