The 5-passenger X5 is available in two trims: xDrive30i and xDrive48i. The xDrive30i is powered by a 260-hp 3.0-liter inline six-cylinder engine, while the xDrive48i boasts a 350-hp 4.8-liter V8. Both trims share the same standard six-speed automatic transmission with Steptronic manual shift mode, as well as BMW's xDrive intelligent all-wheel drive system. Standard equipment includes 18-inch alloy wheels, a Panorama glass moonroof, automatic climate control, wood interior trim and leather upholstery (leatherette on the xDrive30i); an optional third-row seat adds versatility, increasing seating capacity to seven passengers. Safety features on every X5 include anti-lock disc brakes, Dynamic Stability Control with traction control and rollover sensor, run-flat tires, bi-xenon adaptive headlamps, adaptive LED brake lights, front side-impact airbags and overhead curtain airbags for all rows. The BMW X5 carries over with minimal changes for 2009. The naming convention changes to put more emphasis on xDrive and to differentiate performance levels, with new badging on the front doors. A space saver spare wheel and tire is now optional instead of standard on both trims, the rear auto-leveling air suspension is no longer standard on the xDrive48i, and option packages have been restructured.
