In size, the X5 is currently BMW’s largest SUV above the X1 and X3, as well as the more coupe-like X4 and X6. In price, the X5 is more expensive than other BMW SUVs except the X6. BMW is preparing a larger SUV with a bigger interior, for those who need a more comfortable third row.
The 2021 X5 xDrive40i comes standard with a 3.0-liter turbo I-6 with 335 hp and 330 lb-ft of torque paired to an eight-speed automatic transmission. A 4.4-liter twin-turbo V-8 with 456 hp and 479 lb-ft is included on the X5 xDrive50i model.
The 2021 X5 has 33.9 cubic feet of cargo space with the first and second row in place and 72.3 cubic feet behind the front seats. BMW hasn’t released cargo capacity for models with the optional third row.
The X5 earned a five-star overall rating from the NHTSA (five stars is the highest possible rating). The IIHS issued the highest rating of Good for the X5’s moderate overlap front and side crash tests, but the remaining three crash tests have not been conducted.
For the front crash prevention evaluation, the X5 received two ratings. The SUV earned the rating of Advanced for reducing a 12-mph impact by 9 mph and reducing a 25-mph impact by 7 mph thanks to the optional Frontal Collision Warning with City Collision Mitigation. However, the highest rating of Superior was issued to the X5 equipped with the optional Frontal Collision Warning with Extended Collision Mitigation for completely avoiding both 12- and 25-mph frontal collisions. City Collision Mitigation is included in the Active Driving Assistant system that is part of the Driving Assistance Plus Package. Extended City Collision Mitigation is part of the ACC Stop and Go + Active Driving Assistant system that can be added to the Driving Assistance Plus package that also consists of blind spot warning, a surround-view camera system, and a speed-limit indicator.
