The first-generation BMW X5 (code name E53) marked a historic turning point for the Bavarian brand by inaugurating the SAV (Sports Activity Vehicles) segment. Developed at a time when BMW owned Land Rover, it shares some technologies with the Range Rover L322, while being based on a technical platform derived from the excellent 5 Series E39.

For petrol engines, the 3.0i is the sensible and absolutely reliable choice, while the V8s are reserved for enthusiasts with a substantial maintenance budget.
