The BMW 5 Series

The BMW 5 Series has spent the last three decades catering to those who desire a sedan that functions equally well as a prestigious luxury car and a thoroughbred performance sedan. The 5 Series has long been the benchmark by which other sport sedans are measured. This elevated position presents challenges when such a stellar car is due for an update. BMW accomplished its mission with a redesign in 1997 that gave it a look and feel that remained popular right up until the latest redesign last year.

Although the 2004 BMW 5 Series was considered a complete redesign, the changes to the car's basic character seemed more like subtle refinements. It was already a comfortable, capable and highly dynamic machine. The latest version is still all of these things, just a bit more so. In terms of overall philosophy, the largest shift from the previous model came in the form of technology. Several items were pulled directly from the current-generation 7 Series, including iDrive, Active Roll Stabilization (ARS), Active Cruise Control (ACC) and a Harman Kardon Logic7 sound system. Of these features, only iDrive is standard on all 5 Series models, and BMW calls it an "updated" version that is designed to be easier to use. While much of the 7's technology has migrated down to the 5, several advanced technologies made their debut on BMW's midsize sport sedan.

The most exciting of these is dubbed Active Front Steering (AFS), a system that is able to adjust both the steering ratio and the amount of power assist for optimum feel and control under varying driving conditions. All of this technology is wrapped up in an outer shell that reflects BMW's recent styling direction. The 5 Series offers up the same type of sharp edges and harsh angles first seen on the 7 Series in 2002, and subsequently on the Z4 in 2003. But the high percentage of corporate profits delivered by the 5 Series line has forced BMW to play it safer with this model. As such, it has less aggressive body lines when compared to either the 7 Series or Z4. With excellent power and sharp handling, the 5 Series further builds on its reputation as a luxury sedan of unequaled athleticism.

The incorporation of the latest technology and a distinctive look may keep it fresh in the minds of buyers, but in the end, its continued status as a true driver's car will determine its success above all else. Body Styles, Trim Levels and Options: The 5 Series sedan comes in three models: 525i, 530i and 545i. Standard equipment includes automatic climate control, a CD player, a full set of one-touch power windows, rain-sensing windshield wipers and heated power mirrors. Ten-way power front seats are standard, with 12-way power front sport seats and four-way power lumbar support, and 20-way power multifunction comfort front seats with memory as options. The iDrive vehicle management system is integrated into all 5 Series models, while a DVD-based navigation system with voice command and adaptive cruise control are optional. On the audio side, buyers will be able to get a glovebox-mounted CD/DVD changer, as well as a premium-grade Harman Kardon Logic 7 sound system. Other options to consider include adaptive bi-xenon headlights, and a sport package with various wheel/run-flat tire upgrades (up to 18 inches in diameter), firmer suspension tuning and Active Front Steering (AFS). Powertrains and Performance: BMW's 2.5-liter six-cylinder generates 184 horsepower, while the 3.0-liter is rated at 225 hp. The top-of-the-line 545i features the same 4.4-liter V8 found in the flagship 7 Series rated at 325 hp. All models get a six-speed manual standard with a six-speed Steptronic automatic an available option. The 530i and 545i can also be had with BMW's sequential manual gearbox (SMG), a sophisticated transmission that combines the control of a manual gearbox with the ease of an automatic. Performance from the base 2.5-liter is refined, if not exhilarating. The 3.0-liter engine provides the best compromise between speed and efficiency, while the V8 delivers outstanding performance at just about any speed.
