BMW got most of its radical styling ideas out of the way when it introduced the E65 7 Series in 2001. Now, four years later, a slightly revised exterior announces a more refined, powerful BMW flagship that chips away at the styling edges to make it slightly more acceptable without compromising the original, controversial themes. But the big news is that despite gaining two new, bigger V8 engines, there’s virtually no loss in economy, even if there have been significant gains in performance. BMW holds firmly to its role as the luxury brand for the sports-minded.
