2008 BMW 528i

Change doesn't have to be dramatic to be meaningful. Despite revised front and rear styling, for instance, the 2008 5 Series sedan doesn't look markedly different. BMW calls it a "significant freshening." Under the hood, though, six-cylinder models have earned a major power boost—now considered the most powerful six-cylinder sedans and sports wagons to date. BMW also notes that interiors have been "thoroughly revised."

Styling

As before, rear- and all-wheel drive models are offered, the latter indicated by an "xi" suffix to the model number. Last year's 525i models get a new 230-horsepower version of BMW's aluminum/magnesium engine, thus earning 528i nomenclature. Tucking a twin-turbo 300-horsepower engine into the models formerly called 530i results in new 535i and 535xi sedans, along with a 535xi sports wagon. Rounding out the lineup, the "flagship" 550i sedan keeps its 360-horsepower, 4.8-liter V-8, but a new Sport Package includes 19-inch wheels.


BMW's Sport Automatic transmission for rear-drive 535i and 550i sedans promises quicker shifts, with steering-wheel paddles available. The updated Steptronic six-speed automatic transmission is now a no-cost option on all 5 Series models, as an alternative to the standard six-speed manual gearbox.


All six-cylinder models can get a new Sport Package that includes run-flat 18-inch performance tires. For the 528i, the package includes Active Roll Stabilization, 20-way Multi-Contour seats, and a sport suspension. Dakota leather upholstery is included in the 528i's Premium package.

Performance

BMW adds a selection of new technical features, led by a camera-based Lane Departure Warning system. When motion suggests an inadvertent lane change, the driver feels mild steering-wheel vibration. Active Cruise Control gains a Stop and Go feature, which lets the system operate even in heavy traffic. Audio systems can have a new USB adapter for connecting an iPod or MP3 player. BMW no longer offers a sequential manual gearbox.
