- Reliability (3)The N52 naturally aspirated engine is quite robust, but common issues with the electric water pump and oil housing gaskets are frequent concerns.
- Maintenance (2)Parts and specialized labor are expensive; preventative maintenance is mandatory to avoid cascading failures in the cooling and gasket systems.
- Technology (2)While it featured advanced options for its time, the early iDrive system is clunky by modern standards and lacks seamless smartphone integration.
- Comfort (4)Interior build quality is top-tier with very supportive seats, though the ride can feel slightly stiff over harsh pavement due to the run-flat tires.
- Dynamics (4)The hydraulic steering provides excellent feedback, and the xDrive system offers superb grip, though it lacks the pure agility of the rear-wheel-drive variant.
