As intriguing as three turbos sound, at some point variable geometry turbochargers are just going to be better.

BMW X6 M captured running round the ‘Ring is nothing to get excited about – the physics-defying rig was practically born there. A camo-clad X6 M wearing a hood with a massive scoop? Now that’s worth talking about, and it’s precisely what our spy photographers have just snapped at their asphalt-laden Nürburgring office. The extra dose of air is understood to be a requirement of the rumored tri-turbo engine lurking beneath the hood. We’ve already heard how the BMW 5 Series is getting a triple-charged diesel mill. We’ve also heard grumblings of a three-turbo setup for the X5. Naturally, it would only make sense to find the same powerplant making its way over to the nearly identical X6. As we were with that particularly famous alien lady from Total Recall, we’re excited to learn more about this diesel-drinking tri-turbo X6. Horsepower and torque figures should be high enough to make us giddy, while the price tag will most likely have enough numbers to bring us back down to eart. Stay tuned as we learn more about what’s going on under the hood, but for now you, can check out this test mule from a handful of angles in the gallery.
