When the 2009 BMW 7 series was unveiled at the Paris Motor Show last fall, BMW's fifth-generation flagship had an anvil-sized burden to bear. Although the last 7 series was a milestone in the sales department, its design - which foisted Chris Bangle's influence onto an unsuspecting public - was all but universally panned when it was introduced in 2001. And if the exterior wasn't offensive enough (to some), BMW's newly-implemented iDrive system sent many reviewers and owners into unmitigated bouts of rage.

For 2009, BMW has sought to address the fourth generation's foibles while capitalizing on its strengths. And while nothing is more subjective than styling, control interfaces have a huge impact on the overall experience. Find out if BMW has succeeded on both fronts after the break.
