BMW X6 M and X5 M - Click above for high-res image gallery
BMW has done the inexplicable inevitable, expanding its M treatment from cars to SUVs (or Sports Activity Vehicles in BMW parlance). The New York Auto Show marks the world debut of the X5 M and X6 M, and in typical M fashion, the high riders get substantially more power than their more pedestrian variants. Both vehicles get uprated versions of the 4.4-liter twin-turbocharged V8 that debuted in the X6 last year. Power goes from a mere 400 hp up to 555 hp in M form with torque swelling from 450 to 500 lb-ft. While the increase in twist doesn't seem like all that much, BMW is claiming it's produced from 1,500 all the way to 5,650 rpm. The 4.4-liter V8 is direct injected and like other such engines with turbos, torque aplenty is the result. Like the standard version of the V8, the M variant has the intakes on the outside of the cylinder heads with the exhaust and twin turbos planted in the valley between the banks. This new version sports a revised exhaust manifold that combines the flow from both banks into the duo of twin scroll turbochargers. Learn more about the new Ms after the jump.Gallery: BMW X6 MGallery: BMW X5 MContinue reading New York Preview: BMW X6 and X5 get the M treatmentNew York Preview: BMW X6 and X5 get the M treatment originally appeared on Autoblog on Sat, 04 Apr 2009 19:00:00 EST.
