Historically, the 3 series has outsold any other BMW. Be that as it may, the 5 series is actually the bread and butter for the Munich-based automaker. Now in its sixth generation, the 2011 BMW 550i xDrive takes on the super-competitive mid-size luxury sedan market sporting a new platform, powerful and efficient powertrain, improved technologies (I'm looking at you iDrive), updated suspension, as well as the availability of four-wheel drive.
It's even in the running for 2011 World Car of the Year, despite the fact that North America doesn't get the wagon (or Touring) model, or any of the four- and six-cylinder diesel powerplants other markets get.
Here, in North America, we do get the new crossover body-style (aka 5 series Gran Turismo or 5GT) in addition to the keystone four-door sedan models. Available engines include BMW's naturally-aspirated and turbocharged 3.0-liter straight-six gas powerplants rated at 240 hp/230 lb-ft and 300 hp/300 lb-ft of torque, respectively.
