Summary

What Edmunds.com says

Though not the most exclusive choice for a luxury coupe or convertible, the 2008 BMW 650i more than makes up for it thanks to responsive performance, an exacting interior and a less-than-typical price.

Pros

Seamless acceleration from refined V8, nimble handling that belies its proportions, smooth and quiet ride, elegantly crafted interior, ample trunk space in the coupe.

Cons

Limited rear seat room, controversial styling, iDrive system still too complex for some.

What's New for 2008

There are a few changes in store for the 2008 BMW 6 Series coupe and convertible. The previously optional SMG (sequential manual gearbox) transmission has been dropped in favor of a new sport-oriented automatic transmission. Other changes include freshened exterior styling, a new lane departure warning system, a USB adapter for an iPod or MP3 player, and a tweaked version of iDrive for improved user-friendliness.

2008 BMW 6 Series Vehicle Overview

Introduction

For most people, purchasing a large luxury coupe or convertible is entirely an act of passion and indulgence, and right or wrong, outward appearance can make or break the deal. Compared to the sleek offerings from rival manufacturers Mercedes-Benz and Jaguar, well…let's just say the 2008 BMW 6 Series has a great personality. If there is such a thing as a sleeper among the entries in the big-ticket touring class, this is it. Only when you've taken the time to become fully acquainted with its pure driving dynamics, innovative use of technology and lower price of entry does the 6 Series' true beauty become apparent.

In its fifth year of production, the rear-wheel-drive, four-passenger BMW 650i coupe is based on the same platform used for the 5 Series sedan. But BMW aims the 6 Series higher. It has but one engine available, a 4.8-liter V8. Not a single body panel is shared with the sedan, and the front and rear suspensions are likewise calibrated for the 650's lower ride height and sportier intentions. To keep its weight in check, aluminum is used extensively for the suspension, hood and doors. Thermoplastic front fenders and a composite deck lid do their high-tech best to keep the 6 Series feeling spry, though this is still essentially a 4,000-pound car.

BMW equips its 6 Series well in terms of equipment, and you'll find but a handful of features that are optional. Convertibles use a fully lined folding soft top rather than a retractable hardtop, but it's a sophisticated design capable of keeping interior noise to sedanlike levels. The glass rear window opens for ventilation when the roof is up, and can be raised to act as a wind buffer when the top is down. If you don't want to go the convertible route, the 6 Series coupe feels nearly as airy, thanks to its large glass roof section. The glass is too large to slide open, but you can tilt it up slightly for ventilation.

Among high-dollar touring coupes and convertibles, the 2008 BMW 6 Series is easily one of our top recommendations. However, for buyers chiefly interested in style and opulence, the sleeker Mercedes-Benz CL550 and Jaguar XK/XKR will prove more satisfying. The same goes for the highly regarded Mercedes SL550 roadster. For enthusiast types who care about the drive above all else, the smaller Porsche 911 is likely the better choice, as it easily outhandles this plus-size Bimmer coupe.

Yet these cars are all more expensive than the 6 Series. And while cost concerns are seldom of primary concern in this segment, when a car strikes that near-perfect compromise between coddling its passengers and thrilling its driver that the 2008 BMW 650i does, such a value proposition is hard to ignore.

Interior Design and Special Features

Although elegant, the 2008 BMW 6 Series cockpit has a somewhat austere feel compared to its competitors. Still, everything's set up perfectly for driving, with BMW's familiar orange-lit analog gauges dead ahead, a thick steering wheel grip and supportive seating. BMW's iDrive control system reduces button clutter to a minimum, making for a clean dash design but confusing operation of many controls, even with the addition of this year's "shortcut" buttons.

Thanks to its generous dimensions and a panoramic glass roof in the coupe, the 650i feels spacious for two, but four adults make for a tight fit. Both cars have an easy-entry feature to ease access into the backseat, but only the convertible's is power-operated. Trunk space measures 13 cubic feet in the coupe and a still healthy 12.4 in the 650i convertible (10.6 when the top is down), and both cars have a pass-through to accommodate longer items.

Driving Impressions

For a vehicle so laden with technological comfort and safety features, the 6 Series maintains a remarkably direct and visceral driving experience. Although not as nimble as the smaller 3 Series coupe, the 2008 BMW 650i is a very capable performer when driven hard. The Active Roll Stabilization system keeps the big coupe flat around corners, and the lightweight suspension does its part to maintain traction and soak up the bumps without diluting the lines of communication. Regardless of transmission choice, you're sure to enjoy the 650i's 4.8-liter V8. Like every BMW engine we've ever experienced, this V8 is silken and anxious to rev. Although there's a nice surge of power toward the top of the tachometer, there's plenty of torque available at any rpm.
