2008 BMW 535xi

2008 BMW 535xi - But the performance of this versatile power module is even more impressive hitched to a bigger buggy, such as the all-wheel-drive version of the 2008 BMW 5-series sedan. The 535xi's numbers may not seem quite as newsworthy-until you consider its mass: 4042 pounds, 485 more pounds than the coupe in our November '06 test (and about 250 more pounds than the rear-drive 535i, per BMW). The 535xi was further handicapped, albeit only slightly, by the six-speed Steptronic automatic.

No surprise that the coupe was quicker: 0 to 60 in 4.9 seconds, the quarter-mile in 13.6 at 105 mph. The 535xi got to 60 in 5.4 and did the quarter in 14.0 seconds at 102. But consider how the 535xi stacks up against the 550i with its 360-hp, 4.8-liter V-8, as tested last year [“Faster Horses,” November 2006]. The 535xi is only 0.2 second slower to 60 mph and actually 0.2 quicker in 50-to-70-mph blasts. The 535xi is helped by a shorter final drive, but the real key is torque that ramps up early and stays ramped up for a long time. If you're not in a big hurry, it's fast enough and saves some seven grand (nine for the rear-drive 535i) versus the 550i.

Nevertheless, despite the gizmology overlay, these sedans continue to deliver a level of competence, comfort, and response that sets the pace in their class.
