BMW Faqs

BMW’s 5 Series sedans are well known for their sports-car-like performance and handling. The top-of-the-line 550i is the priciest and most powerful version and like the 525 and 530 models, it receives only minor updates for 2007, most of which are high-tech gadgets. Styling and major mechanical components carry over unchanged.

Primary among the new high-tech upgrades is an enhanced BMW Assist safety/communication system (similar to General Motors’ OnStar) that offers services like collision assistance and stolen vehicle recovery. Every 5 Series model now comes with four years of BMW Assist; by comparison, it is a $685-per-year option on the 3 Series.

The 2007 550i gains an input that allows iPods and other portable devices to be played through the vehicle’s audio system. A high-definition (HD) radio receiver is newly optional ($500). This new system, which debuted on the 2006 6 Series, delivers CD-quality digital sound on FM stations that broadcast in the new format, with FM-quality audio on AM stations.

Unlike satellite radio, HD radio is free, all broadcasts are local in nature and the radio units can receive standard analog broadcasts in addition to HD digital programming. As of spring 2006, more than 700 stations across the U.S. were broadcasting in HD radio, with more than 3,000 committed to adding the new format.

The 5 Series line underwent a major makeover for the 2004 model year that included a new platform, powertrains and radically different styling. The 550i received a larger V8 for 2006 and a name change in the process it was previously called the 545i. The 550i comes only as a sedan and with rear-wheel drive. Those looking for all-wheel drive must step down to the six-cylinder-powered 525xi or 530xi. A wagon variant is available only as the 530xi Sport Wagon.

The 550i’s aluminum 4.8-liter V8 is the same engine offered in the larger 7 Series sedan. It generates a strong 360 hp and 360 pound-feet of torque and is mated to a standard six-speed manual transmission, a six-speed automatic gearbox with manual-shift capability or a six-speed clutchless Sequential Manual Gearbox.

Although the latter two transmissions are optional, they do not cost extra. Stability control (which uses throttle and brake control to help minimize wheel spin and prevent a loss of control during extreme handling maneuvers) is standard.

The 550i is decently equipped, but a vehicle with a starting price of $58,500 should include such items as heated seats ($500), rear side-impact airbags ($385), navigation system ($1,800), premium audio system with CD changer ($1,800) and split-folding rear seat backs ($475). Unfortunately, BMW’s confusing iDrive control system carries over for 2007 and is the hub for operating all in-vehicle systems.

Although more separate buttons for radio and ventilation have been added over the years, iDrive remains a chore to use and does the opposite of what BMW originally intended, which was to simplify control operation.
