2008 BMW 5-Series: Road Test

ACCELERATION

Despite a smallish engine for the class, the 528i has sufficient power for most needs, even with the automatic transmission. The 535i is sprightly from a stop and in passing and merging situations, though touchy throttle response can frustrate drivers in stop-and-go commuting. The 550i is potent at all speeds; it did 5.5 seconds 0-60 mph with automatic transmission in our test. The conventional automatic works well but can be tardy on downshifts in fully automatic mode. Using the manual shift gate or available steering-wheel paddles helps. The manual transmission shifts smoothly. No M5s or 5-Series cars with the automated manual transmission have been made available for testing.

RIDE QUALITY

The 5-Series' ride/handling combination is among the world's best, at least with the base suspension. Models so equipped are surprisingly supple over bumps. Even with the Sport Package's stiffer suspension and lower-profile tires the ride never becomes harsh, though ruts and pavement cracks register with authority.

QUIETNESS

Wind rush is minimal at highway speeds. Road noise is noticed only with the Sport Package's high-performance tires, and they're fairly hushed on most surfaces. Engines are smooth, producing only a muted growl during aggressive acceleration.

DETAILS

Elegant interior decor benefits from top-notch materials. Build quality is generally impressive, though one test 528i suffered some "orange peel" surface texture in its paint.

ROOM/COMFORT (REAR)

Seats are comfortable and supportive. Headroom is adequate for average adults, but legroom and foot space can grow tight with the front seats far back and lowered.

VALUE WITHIN CLASS

The 5-Series bristles with technology, but not all of it is beneficial. Active Steering is a love/hate affair, and the iDrive control center can be downright confounding. But Active Roll Stabilization is truly useful and helps BMW maintain the 5-Series' world-class handling without compromising its admirable ride quality.
