The 2008 BMW X5 is a luxury midsize SUV that arrives in two distinct trims: 3.0si and 4.8i. The 3.0si is powered by a 260-horsepower six-cylinder engine, while the 4.8i receives a more potent 350-horsepower V8. Both trims utilize a six-speed automatic transmission, and BMW's xDrive all-wheel-drive system is standard. BMW's iDrive interface controls the audio, navigation, and climate systems on a high-resolution 8.8-inch display screen. Standard safety features include stability control, antilock brakes, front side airbags, front and rear side curtain airbags, and also front and rear parking sensors. For 2008, BMW enhanced X5's interior with newly standard features like a power tailgate, an MP3-player audio jack, and a four-zone automatic climate control system on the V8 model.
