The X5 is an IIHS Top Safety Pick, also taking top marks in NHTSA crash tests, earning 5 stars in most tests, except for a four-star frontal impact rating for passengers and a four-star rollover rating.
Edmunds points out BMW X5's standard "antilock brakes, traction control, stability control, brake drying and standby." Regarding the last feature, Cars.com explains it keeps "the discs clean during inclement weather" to maintain short stopping distances. Kelley Blue Book likes the higher-tech features such as "Hill Descent Control" and "two-stage front, front seat-mounted side and front and rear head-curtain airbags," which come standard on the 2010 X5. Cars.com praises the adaptive brake lights, which "illuminate over a wider area under heavy braking." Edmunds observes that the parking sensors can help avoid minor fender-benders, while MyRide.com notes the safety-enhancing "anti-roll stability system and run-flat tires as part of a Sport Package."
ConsumerGuide warns that "rear headrests partially block the view astern, but visibility is good otherwise, aided by available front and rear obstacle detection." MyRide.com concurs, finding "good visibility all around," thanks to 2010 BMW X5's large mirrors, big windows, and rearview camera.
