2009 BMW 3 Series

There have been many imitators over the years, but when you're in the market for a comfortable, everyday car that's as equally at home canyon-carving at triple-digit speeds as it is taking the kids to school, the BMW 3 Series is hard to beat.

Introduced as a 2006 model, the fifth-generation of BMW's iconic 3 Series sport sedan has continued this tradition -- especially after receiving a much-needed horsepower upgrade the following year. But recently, the Munich automaker's rivals have been catching up. Offerings from Mercedes, Infiniti, Cadillac, and Lexus now offer the 3 Series the stiffest competition it's seen in some time.

So for its third year on the market, BMW is giving its bread-and-butter model a healthy list of small improvements to make it even more desirable. Among the changes are (slightly) revised styling, an upgraded interior, simpler iDrive interface, in-car Internet access, a new audio system, and an optional dual-clutch transmission. The automaker's sublime 3.0L inline-six, available in naturally aspirated and twin-turbo forms, remains the same, but for the first time BMW is also giving Americans the option of a diesel powertrain -- and it could turn out to be the best of the bunch.

As before, the 2009 3 Series will be available as a sedan, wagon, coupe, and hardtop-convertible in either 328i and 335i form, utilizing a 3.0L inline-six good for 230 hp, or 300 in twin-turbo form. Styling changes are subtle but numerous and include a new hood with additional character lines, new side mirrors, reshaped taillamps, and a sharper crease running down each side. A revised front end makes the previous version's lines more prominent and adds a larger lower air intake, while the chrome accenting the car's signature kidney grille is less noticeable. Though at a distance the updates are hard to spot, overall the 2009 3 Series has a slightly sharper, more muscular appearance than its predecessor. All models receive LED turn signals and taillights as well.

Inside, BMW's changes are equally restrained, with new colors and materials as well as additional storage. A new stereo includes an 80-gig hard drive, USB input and optional iPod connector, while the nav system sports an 8.8-in. display. In addition the new 3 will be available with ConnectedDrive, the automaker's new EDGE-speed, in-car Internet access system, and now routes planned on the Internet can be fed directly into the 3's nav system, saving the hassle of inputting destinations manually. Like in the 7 unveiled earlier in the week, for 2009 the 3 Series also gains a revised iDrive system with more intuitive menus and drops the basic scroll wheel for a new controller allowing turn, push, and tilt motions. Major functions also can be accessed via four direct-select buttons, and much of the system is now voice-activated.
