The most obvious change is the starter. The 3 Series sedans no longer have a keyed ignition switch, relying instead on a slot-type key fob and a starter button. The fob goes in a slot next to the steering column, and you push the button to fire up. The Comfort Access option ($500) makes everything automatic. With fob in pocket, the doors unlock automatically as the driver approaches and the seats are waiting in their proper position. The driver just pushes the start button, and pushes it again when it's time to get out.
Seats have always been one of this car's strengths, and the new ones are better than ever. Even the standard-trim front buckets provide excellent support without feeling too hard. The manual adjustments work great, though we recommend using them when the car is parked. The 330i gets power adjustments with three memory positions coded to the key. The 10-way power seats that come with the Sport Package are outstanding. Additional back and bottom bolstering make them a bit harder to slide into, but we'd rather have them during a spirited drive.
The new instrument panels have a pronounced horizontal format, with more community and less driver orientation than before. There are actually two: standard, with a single bubble or hood over the instrument cluster, and optional, with the navigation system. The option dash features a double wave,'' with a second hood above the navigation screen at the top of the center stack.
The front door panels are different, too. The passenger side has a sloped, vertical door pull, while the driver's door lays the door pull horizontally in the arm rest. Moreover, the new doors address one of our biggest gripes with the old 3 Series interior. Window switches are now clustered near the driver's arm rest, where they're easier to locate without glancing, rather than spread around the gear change on the center console.
The soft vinyls and plastics in the new 3 Series sedans are an improvement in both touch and appearance, and they put the car more closely in line with the best cars in this class for materials and workmanship. Burr walnut trim is now standard, and there's a lot of it on the dash and doors. BMW's Leatherette vinyl is not the least bit tacky, though the optional leather is soft, thick and tight. The new 3 follows BMW's tradition of soft orange backlighting for the instruments. Some will like it, some won't.
For the first time, the 3's automatic climate control features separate temperature adjustments for driver and front passenger. There's also a new mist sensor that measures moisture on the windshield and automatically adjusts the defroster, as well as a heat-at-rest feature that keeps the cabin heating for a time after the car is turned off.
The standard in-dash single-CD player is easy to operate and sounds good, with 10 speakers and separate subwoofers under the front seats. We'd have no problem living with it, but the 330i automatically gets an upgrade called Logic 7. This system adds wattage and three speakers, with the latest digital sound processing and surround technology. Audio controls on the steering wheel work well, once they're mastered.
BMW's multi-layer, mouse-style iDrive interface is optional in the new 3 Series sedans, but if you want the DVD-based GPS navigation system, you'll have to take iDrive. We'd probably do without the nav system, and have encountered few people who remotely like iDrive. Yet there is this in BMW's defense: The art of driver-computer interface remains in its infancy, and no one does it very well.
In certain respects the 3 Series cabin is more consumer-friendly than ever. There are more storage pockets and nooks than before, and those in the doors are much larger. The new climate-controlled center console is a huge improvement, in both function and appearance. So are the cupholders.
Rear-seat accommodations are substantially improved, as well. For starters, there are now rear air vents that can be separately adjusted for both temperature and air-volume. There's also more space, particularly in front of the knees. Remember: this is still a compact car, and rear passengers with long torsos will still feel hair rubbing on the headliner. The center position is still best left to children. Nonetheless, the rear seat feels more spacious than before, and puts the 3 Series on better footing with the roomiest cars in the class."
