First Drive Review

The BMW 3-series is without question one of our favorite cars, reigning on our yearly 10Best Cars list for the past 16 years. The current and much-praised, fifth-generation E90 version is no doubt the best, and is among the most rewarding cars to drive at any price. For 2008, and to no one's surprise, BMW is adding a convertible version, just as the company has for the past 20 years.

But, this is BMW's first foray into the expanding, hardtop-convertible parade. Other notable features are a much-improved, rapid-shifting six-speed automatic; special reflective leather to keep the seats cool (up to 30 degrees cooler than conventional leather) when the top is down; and, of course, the spectacular 300-hp twin-turbo inline-six that was introduced in last year's 335i coupe. In the U.S., the convertible will be offered as the aforementioned 300-hp 335i—the model we got an early drive in—as well as a 230-hp 328i when it goes on-sale at the end of March. Pricing isn't yet finalized, but the convertible premium will likely not change much from the outgoing model's, so expect to pay about $7000 more than comparable coupes; roughly $43,000 for the 328i and $48,000 for the 335i.

Changes from convertible to coupe in 23 seconds

Hardtop convertibles offer numerous advantages over their soft-top competitors, including coupe-like quietness and excellent visibility when the top is up. BMW reports that the rear side windows have grown 30 percent in the new 3-series convertible, while overall visibility is up 38 percent. To our eyes, visibility out of the convertible is essentially equivalent to that of the coupe.

Looks-wise, you probably won't spot the new convertible by its 3-series-coupe-like front-end, but rather from the rear, where the coupe's flowing roofline is replaced by a distinct line where the convertible's roof meets the trunk.

BMW's new top is a three-piece unit and, at the push of a center-console button or the key fob, stacks the front panel on top of the center panel, then the rear panel on top of both of those before disappearing into the trunk in 22 seconds. It takes a second longer to reverse the process, which is about seven seconds quicker than its closest competitor, the Volvo C70.

The downside of folding hardtops is that they're heavy and that the top can hog most of the trunk space when down. In the 3-series' case, the top itself adds 300 pounds, while the extra chassis reinforcements pack on another 150, so expect a 335i convertible to weigh about 4000 pounds. To BMW's credit, however, the convertible retains a 50-50 weight distribution and is claimed to have 50-percent stiffer torsional rigidity than the previous 3-series convertible. From the driver's seat, we can tell you that the new 3-series is among the stiffest in its class, with almost no perceptible quivers felt through either the seat or steering wheel.

The convertible's 12-cubic-foot trunk is actually one cube larger than the coupe's, but shrinks to 7 with the top down; still leaving usable space beneath the panels. That also compares favorably with the Volvo C70's 13 cubic feet top-up and 6 top-down. However, the Volvo has a nifty loading feature that electronically motors the roof panels out of the way for easier access to the trunk space with the top down. On the BMW, that feature is optional (part of the $500 Comfort Access, which also includes keyless unlocking/locking and starting) and doesn't work as well as there's no button (instead you must click the key fob twice), and even then doesn't make loading as easy as the Volvo does. However, the 3-series has a folding rear seat and a 16-inch-wide trunk pass through to accommodate the must-have set of golf clubs under the folded roof.
