2009 BMW X6 – Click above for high-res image gallery
BMW has officially announced changes for its 2011 BMW X6, and the big news is that the German automaker will swap out its twin-turbo N54 inline-six in this sport utility for the new twin-scroll single turbo N55 mill, just like it did in the new 5 Series. The move continues BMW's drive toward simplifying its engine options while at the same time providing X6 owners with stronger acceleration and increased efficiency. BMW claims the N55 matches the twin-scroll N54's power numbers while also cutting weight from the engine bay. And since this bubbly crossover weighs in at a rotund 4,900 pounds, we're thinking every pound lost is a good thing.

The twin-scroll inline-six will produce 306 horsepower and 295 pound-feet of torque in the X6, six more ponies and five fewer lb-ft than the outgoing twin turbo model. Both the X6 35i and X6 50i will also receive ZF's eight speed automatic transmission for the 2011 model year. The eight forward gears will even further improve efficiency while also deliver smoother shifts.

      I cannot live without at least a 12 speed transmission. What is wrong with car companies these days?

        You're behind the power curve then! You need an infinite speed automatic!

        Pfft! My mountain bike has 18 gears sucka!

        Read it and weep.

      Will it be able to go up grassy or snowy hills now?

      Will the fancy pop-up glove-box still open on the other side of the world?

      Take a sporty sedan... and an SUV... combine the drawbacks of both... and you have this.

      Aerodynamic roofline means nothing when the thing is as big and tall as a house, and blunt on the front.

      All the CUV cred in the world would be hampered by a lack of practical interior space.

      CHOOSE ONE OR THE OTHER.

      The X6 and 5GT are both too huge. Since they are both forays from the 7 series chassis, down toward the 5-series equipment and price points...

      I hope they do something nice, and produce a legitimate 5-door sport sedan, not a CUV behemoth... from the 5-series chassis, down toward 3-series equipment and price points... sleek with a 5-door profile, but lower, and sportier looking... which the 5-series sedan is a good starting point for.

      Something to compete with Audi A5/S5 Sportback. And bring it to the US, with optional AWD, please, since Audi won't.

      6-speed manual or 7-speed DCT, please. 8 gears is just marketing fodder, to compete with Lexus' 8-speed.

      A wide-powerband torquey turbocharged 6 should need relatively FEW gears... more gears are only required when the powerband is narrow, and the engine isn't as flexible outside it's power-band.

      "single turbo" in the headline, "twin-scroll" in the article...?

      It's gonna need a lot more than 306 hp and 295 lb/ft to outrun the ugly.
        • 4 Years Ago
        You don't need performance figures, the sale numbers are already enough to outrun the ugly. This car is a gold-mine for BMW, they would be stupid if they changed it. It sells like hot cakes. And I bet they will rather listen to the opinion of thousands of buyers instead of few kids on forums/blog where 90% of them drives some rusty junk.

      Two-and-a-half tons of bloated ugliness.
