After a redesign last year, the 2008 BMW X5 receives only minor changes. This midsize SUV seats up to seven and is offered in two models. The 3.0si has a 260-hp 3.0-liter 6-cylinder engine. The 4.8i has a 350-hp 4.8-liter V8. Both come only with automatic transmission. Maximum towing capacity is 6000 lb. Standard seating is for five, but an optional 3rd row expands capacity to seven. All X5s have all-wheel drive without low-range gearing, traction control, antiskid system with rollover sensors, and hill descent control. Front side airbags are standard, as are curtain side airbags that cover the first two seating rows and include rollover deployment. All X5s have BMW's iDrive that uses a single knob to control entertainment, communication, navigation, and climate functions. Available features include Active Roll Stabilization, which counters body lean; Active Steering, designed to quicken low-speed steering response; and steering-linked xenon headlights. Also available are a navigation system, head-up instrument display, DVD entertainment, rearview camera with front/rear obstacle detection, and BMW Assist concierge service with wireless cell phone link.
