Introduction

The BMW 5 Series puts an emphasis on the driving. This mid-size luxury sedan remains a true sports sedan in any of its variations, including the 530ix wagon and other models equipped with all-wheel drive. Regardless of engine size or equipment level, the BMW 5 Series delivers lively acceleration, precise handling and outstanding brakes. It's available with a conventional manual transmission, which is increasingly hard to find in this class. For 2007, the 5 Series offers two new options. BMW's Night Vision safety system uses a thermal-imaging camera to highlight pedestrians and animals on dark roads, while HD Radio is designed to bring CD-quality digital audio to radio broadcasts. Now in its fourth year on the market, the styling of the current 5 Series models has become familiar, perhaps less jarring than it was when first revealed. And while there are no significant changes for the 2007 model year, the 5 Series is anything but stale. For 2006, BMW introduced new engines across the board, including a high-tech magnesium alloy six cylinder for the 525i and 530i and a larger, more powerful V8 for the 550i. Behind its kabuki-eyebrow headlights, the 5 Series is a true driver's car, with more model choices than most cars in its class. Even the base 525i boasts spirited performance, with decent fuel economy to lower operating costs. The more powerful six-cylinder in the 530i matches some V8s, while the 550i delivers true high performance by any definition. The limited-production M5 can out-accelerate, out-brake and out-corner some expensive sports cars, with comfortable seating for five. There's a wagon for those who want more room for cargo. And BMW's x-Drive full-time all-wheel-drive is available for drivers in the Snow Belt. This car has just about everything you could ask for in a luxury car. It has the features, comfort and convenience of full-size luxury sedans, the sporting character of smaller ones, and a good compromise between interior space and physical bulk. In many respects, it's the benchmark for critics and auto industry engineers alike. As such, the 5 Series is loaded with technology, and some of its systems have a dark side. The i-Drive point-and-click control system, for example, takes time and energy to learn, and drivers who aren't willing to invest the energy, or those who just prefer to keep things simple, might want to look at a competitor. But those who place a premium on driving satisfaction should start their shopping here. The BMW 5 Series sedans are available with six- or eight-cylinder engines or an ultra-high performance V10, and manual, automatic, or automatic-shifting sequential manual transmissions and optional all-wheel drive. The 5 Series Sport Wagon is offered only with a six-cylinder and all-wheel drive.

Walkaround

Many buyers will find the BMW 5 Series a near-perfect size. It seems more substantial than some small luxury or sport sedans, with more usable interior space. At the same time it's not so physically bulky as large sedans, and therefore easier to maneuver in tight spaces and to park. The 5 Series sports BMW's now-familiar corporate design themes, introduced on the larger 7 Series sedan and subsequently applied to the smaller 3 Series. BMW's new approach to styling has been discussed as frequently as any in the car world, and more than occasionally criticized. On the 5 Series at least, the curvy front-end, flat sides and high rear deck stand out less than they once did. That may simply mean we've grown more familiar with the shape, rather than more appreciative. The critics contend that, with the flared-nostrils look in front and the chunked-off shape of the trunk lid, the 5 Series seems almost like two halves taken from different cars. In our view, the lines create a fairly compact appearance, and that may be part of the problem. The 5 has the appearance of a well-built mainstream sedan, and that may not be the precedent one expects for an expensive European job. In any case, the look doesn't seem to have hurt 5 Series sales. The comma-shaped, wraparound taillights apply a technology introduced by BMW that has spread to a number of makes. The company calls them adaptive brake lights, and they illuminate more intensely, over a larger area, when the anti-lock brake system engages, in other words when the driver is braking as hard as possible. The point is to inform drivers following that it's stopping quickly, possibly in an emergency situation. It could help, if the driver following correctly interprets the increased intensity of the brake lights. BMW re-introduced a 5 Series wagon for 2006. The big difference, of course, lies behind the rear roof pillars and back seats, where the 5 Series Sport Wagons offer more load-carrying potential and versatility than the sedan. The rear gate opens electrically, with a switch on the key fob or dashboard, and swings very high for easy access to the load floor. A big reflector on the bottom of the gate adds an element of safety in darkness. The lift gate has a soft-close feature. When it's lowered, it automatically sucks itself shut, no slamming required. The glass window opens separately, which is convenient when dropping a briefcase or a couple of bags in back. New for 2007: Xenon adaptive headlights are now standard on the 530i and above. The xenon high-intensity discharge headlights offer a brighter, more intense, more white light that appears blue when we're used to seeing halogen lights with a warmer, relatively yellow light. Adaptive means the lenses turn slightly with the steering, throwing light around a curve in the direction of travel.

Interior Features

BMW's current 5 Series sedans are noticeably roomier than the previous-generation, pre-2004 models. Front passengers have a fraction more shoulder and head room, but the improvement is more obvious in the back, where there's more shoulder room and a lot more legroom. Increased cabin space put the 5 Series on better footing with key competitors like the Mercedes E-Class, Audi A6, and Lexus GS. The finish and quality of materials is nice. Soft plastics covering the dashboard and doors are handsome and rich to the touch. The seats feature a draped-leather look, with the upholstery hung loosely over the seat frames. Leather inserts in the front door panels compliment the seats. The standard 5 Series seats are very good, with above-average support and just enough give to keep from feeling hard. The seats in the optional Sport Package have so many adjustments that those who lean toward obsessive/compulsive may start stressing out as they try to settle in. If you can get them just right, save the position in memory, because these are some of the best seats in the business. They're firm, but not church-pew hard like the previous-generation sport seats. The 5 Series dashboard applies BMW's familiar double-wave theme, with one wave or bubble over the instrument cluster, defining the driver's area, and another that begins over the dash center and sweeps toward the right side. From a functional view point, it's an effective design. The instrument cluster features two gauge pods, with the gas gauge wrapped inside the analog speedometer and a miles-per-gallon gauge inside the tach. The tachometer has a variable warning LED that circles the gauge. When the engine is cold, this LED extends to 4200 rpm, then gradually increases the rpm limit to the redline as the oil warms up. The center dash is dominated by a large electronic screen that displays various control functions, system readouts and the navigation map or Night Vision image when the car is so equipped. There are vents below the screen and on either side off the steering column that move an impressive quantity of air with minimal fan noise. Three big climate control knobs sit below the display screen, for fan speed, temperature and airflow direction. There's also a volume knob next to the CD slot, a station selector on the right steering wheel spoke, and phone controls on the left spoke. Window switches are just above the armrest, and right where the hand naturally rests. In short order, these knobs will become the 5 Series driver's best friends. That's because almost everything else, including some basic stereo functions, is controlled by i-Drive, the computer interface that manages virtually every system in the car. The master control is a big aluminum knob on the center console between the seats. The knob is easy to locate from the driver's seat without a glance, and with each move of i-Drive, menus appear on the video screen. In effect, the system works something like the point-and-click operation of a computer mouse, though there is no cursor. The problem is that it can be confusing to use i-Drive to wade through various menus to get to the function that needs adjustment. At best, it's difficult to master, and while BMW has simplified the system by reducing the number of movements for the main control, and adding a Main Menu button, it still takes time to get used to i-Drive. Operation becomes more intuitive with time, but many still find it a cumbersome way to make everyday adjustments. HD Radio, new for 2007, delivers digital audio quality, with FM reception that is supposed to sound like a CD and AM that replicates traditional analog FM. Our test car had HD radio, and it's great, with a caveat. When it locks on a signal the clarity and fidelity is amazing, especially on the AM band. The problem is that, depending on where you're driving, the radio can fluctuate from HD to standard broadcast as signa
