BMW's 5 Series delivers just about everything you could ask for in a luxury sedan. It offers the features, comfort and convenience of full-size luxury sedans, the sporting character of smaller ones, and a better compromise between interior space and physical bulk. The BMW 5 Series has long been a big seller in the most popular, most competitive class of luxury cars. It's the benchmark for critics and auto industry engineers alike.For 2004, the 5 Series is redesigned down to its aluminum wheels for the first time in eight years. BMW's premise for the all-new 5 Series seems to be more: more room, more equipment and more sophisticated technology, including BMW's controversial iDrive computer interface. Unfortunately, the new 5 costs more, too, and it follows the contentious styling theme introduced on BMW's full-size 7 Series.
BMW's smaller 3 Series may be the bigger seller, but the 5 is the company's original sports sedan and the oldest nameplate in its line-up. Since the 5 Series nomenclature was introduced in 1975, BMW has completely overhauled its mid-line sedan five times. The redo for 2004 is as extensive as any the company has undertaken. Because this sedan generates a quarter of BMW's profits worldwide, the engineers in Munich spared no expense in the redesign.
