Walkaround
Each of the major players in the mid-luxury class has its own appearance. The new Audi A6 is rounded and chunky, the Lexus GS sedans are swoopy and sporty, the E-Class Mercedes-Benz looks, well, like a Mercedes, the Acura TL is conservative, while the Infiniti J30 is not, and the Cadillac Catera is unobtrusive. Amid these contenders, the 5 Series manages to stand out by presenting a beautifully proportioned elegant face to the world, one that is recognizably BMW in origin from twin kidney-shaped grille to the large taillight clusters in back. The overall shape of the 5 Series body is a well-done evolution of a handsome basic design that dates back more than two decades. There's more to the 5 Series than good looks. Its body shell is extremely rigid, a plus in terms of both safety and noise reduction. With its low 0.30 coefficient of drag, the 5 Series is one of the most aerodynamically efficient sedans on the market. Also aiding in keeping unwanted noise at bay are foam-filled body cavities and redesigned door seals. Two 5 Series models are available. The junior version is the 528i, powered by an inline 6-cylinder engine. Its upscale brother is the V8-equipped 540i. Aside from their powerplants, the two 5 Series sedans are remarkably similar, differing mainly in amenities, minor detailing and trunk lid badges. Manual transmissions are standard with either engine; the 528i gets a 5-speed unit, the 540i a 6-speed. A 4-speed automatic transmission is available for the 528i, a 5-speed automatic is an option for the 540i. A sports suspension package is standard on the manual-gearbox 540i, optional on the other models. The sports suspension comes packaged with 17-inch wheels. Otherwise, 15-inch (528i) or 16-inch (540i automatic) rims are supplied. Traction control is standard on all but the 540i manual, which gets the enhanced Dynamic Stability Control system, a computer-controlled unit that uses inputs from a variety of onboard sensors to apply brakes and/or reduce power in extreme situations that might otherwise end in the car going out of control.
Interior Features
Good looks and luxury fittings mean little if occupants don't feel secure. They will in a 1998 5 Series. If the optional rear-seat side airbags are ordered, the BMW cabin has a total of eight airbags to protect driver and passengers in the event of a crash. Most notable is BMW's new Head Protection System, or HPS. The system consists of a tubular airbag on each side of the cabin, anchored in front at the base of the windshield pillar, in back on the roof above the rear door. In the event of a side impact, the HPS tube inflates, breaks away from the trim panels that conceal it, and serves as a barrier between heads and hard surfaces that would cause serious injury. Tests have shown the head protection system markedly improves survivability in side impacts. Safety may be given top billing, but the 5 Series interior isn't lacking in comfort and appearance. Trim is sumptuous, whether leatherette with brushed-aluminum accents (528i) or soft leather with burl walnut panels discreetly applied to center console, dashboard and door panels (540i). Power front seats with 10-way adjustments are standard, as are power tilt-and-telescope steering column and electric windows, mirrors and door locks. The automatic climate control has separate temperature settings for driver and front-seat passenger, and the standard audio system has 10 speakers (528i) or 12 (540i). A power moonroof comes standard on the 540i, optional on the 528i. About the only option one might want to add are heated front seats. Leather upholstery can be ordered to replace the 528i's leatherette and power-operated rear window sunshades and manual pull-up rear side window shades can be added to any 5 Series. Deeply bolstered manually adjustable sport front seats are available at no cost for the 540i.
