Because the 6-cylinder engine is short on low-speed torque, it needs to reach past 3000 rpm before it can provide much zip. With an automatic transmission, the 528i gets winded while climbing hills, or when you need to pass other vehicles quickly. A test manual-transmission 530i did 0-60 mph in just 6.7 sec. Power is more than sufficient with the smooth V8 engine, which yields quick takeoffs and spirited passing with its 5-speed automatic transmission. A 528i with manual shift averaged 20.9 mpg in a blend of hard city and highway driving. With automatic, mileage dipped to just 18.8 mpg. An automatic 540i got just under 16 mpg, despite many miles of freeway driving at moderate speeds. The 525iT wagon later averaged 17.4 mpg with automatic transmission. Both engines demand premium fuel. Steering on either model is fluid and precise. Each model is surefooted and agile, despite a surprising amount of body lean through tight turns. The BMW's standard suspension soaks up most bumps easily and delivers a comfortable, stable highway ride. The tighter optional sport suspension gives more jiggle and thump on imperfect surfaces. Despite the roomier interior in this generation, a wide center console steals some space up front. Also, a large driveline tunnel divides the rear seat. That leaves real room for only four adults--not much for a car with the exterior dimensions of the 5-Series. Head and leg room are ample in the rear seat, partly because the seat cushion is low and short. Though not wide, the trunk has a long, flat floor. BMW's take-charge driving stance is appealing, though some minor controls are bothersome. Most notably, the complicated audio/climate/trip computer display can be quite confusing at first.

Value for the Money
Overall driving pleasure is a sure thing on either model, but especially the potent 540i. You get more space than a 3-Series, with almost as much agility. And the 5-Series is only a little less luxurious than the big 7-Series sedan.
