The 5 series is the mid-size sedan that buyers covet and other manufacturers aspire to duplicate. While the bold, angular exterior styling is a departure from previous generations, it has worked well with consumers. The wide range of powertrains offer something for the image conscious and performance enthusiast as well. A long list of electronic driving aids includes active steering, the iDrive centralized navigation system, HVAC, and audio system controls. The navigation system gives you the option of a "heads up" display of feedback on the windshield. The 545 V8 model is the performance champ with a bhp of 325, but a V10 M5 is on the way.
