The BMW X5 comes in two variations, distinguished primarily by engine type, both with all-wheel drive. For 2008, both models get an upgrade in standard equipment, new engines and a six-speed automatic transmission.
The BMW X5 3.0si ($46,200) is powered by a 3.0-liter inline six-cylinder engine delivering 260 horsepower. It comes well equipped, with a 12-speaker, single-CD stereo, niceties such as a choice of wood trim, rain-sensing wipers, power tilt/telescoping steering wheel, driver's seat memory and, for 2008, a power sunroof. The standard upholstery is BMW's Leatherette vinyl, and the wheels measure 18 inches in diameter.
The BMW X5 4.8i ($54,800) is powered by a V8 with 350 horsepower. The 4.8i model comes standard with leather upholstery.
The Sport Package ($3,700) adds Active Roll Stabilization and Electronic Damping Control suspension, 19-inch wheels, heavily bolstered sport seats and Shadowline exterior trim. Other option groups include the Premium Package ($2850 for the 3.0si, $1,850 for the 4.8i), which adds front-seat power lumbar support, Ambiance Lighting, auto-dimming interior and exterior mirrors, a digital compass, power-fold exterior mirrors, Bluetooth phone interface, BMW Assist with a 4-year subscription and leather seating for the 3.0si.
The Technology Package ($2,600) includes Park Distance Control, Rearview camera and a navigation system with voice command and Real Time Traffic information. The Cold Weather Package ($900) adds retractable headlight washers, heated steering wheel, heated front seats and a ski bag with rear-seat pass-through, while the Rear Climate Package ($900) adds four-zone climate control, manual rear sunshades and privacy glass.
Options that are standalone include a premium sound system with 16 speakers and a six-CD changer ($1,800), Active Ventilated 20-way front seats with a massage feature for the driver ($2,100), rear-seat DVD entertainment system ($1,800), ultra-soft Nappa leather ($1,000), Comfort Access keyless starting ($1,000), satellite radio ($595), iPod and USB adaptor ($400), and HD radio ($350). A powered Automatic Tailgate ($500) is offered for the first time in 2008.
The Insurance Institute for Highway Safety (IIHS) has designated the 2008 X5 a Top Safety Pick, and it performs better than many SUVs in the insurance industry's crash tests. Standard safety features include front airbags with two-stage activation, side-impact airbags built into the front seats, and curtain-style airbags providing head protection for outboard passengers front and rear. The X5 also comes standard with the full array of active safety features, including electronic stability control and advanced anti-lock brakes with a pre-loading and water-sweeping feature. The 2008 models come standard with run-flat tires, which allow operation at 50 mph for up to 90 miles when completely flat.
