BMW is continuing to revamp its engine lineup, and the most recent model to receive a new unit is the X6 in its 2011 model year, which saw the old twin-turbo N54 replaced with a brand new and more efficient single turbo 3.0-liter N55 unit, which is currently being used by the 5 Series GT.
Not only does the new engine weigh less, which for the big SAV means something, but it also produces a bit more power, outputting 306 HP and 295 lb-ft of torque. Future X6 owners, no matter what their engine choice, will also be able to choose an optional ZF eight-speed automatic gearbox, which provides not only smoother gear shifts but also improved efficiency.
Overall, BMW knows staying ahead of the pack is important, and these new changes are more than welcomed by fans.
