Conservative is one way to describe the X5's styling. Bland is another. It's not entirely without character, but at the same time it doesn't evoke the history of the Range Rover or the sheer excess of the Cadillac Escalade. The X5 isn't unattractive, either, and its interior, though also conservative and a bit dark, is modern and mostly unobjectionable from an aesthetic standpoint.
The aggressive X5 M takes the look into aggressive territory, however, thanks to its huge air intakes and large wheels.
Four total trim levels are available on the 2011 X5, including the xDrive35d, xDrive 35i, xDrive50i, and X5 M. As the trims refer to engine size with the exception of the M, there are no significant exterior styling differences between the three standard vehicles, though the M model gets a more dramatic front-end treatment and unique wheels.
