The X3 is derived from the E46 (3 series) sharing many identical parts but is much heavier. Various reinforcement measures were necessary to guarantee the required level of rigidity even in the event of a crash.
Thus the front axle (2joint spring strut as in the X5) is bolted at 8 points, the front end is stabilized with a suspension cross brace (load factor higher than for the M3), seat crossmembers and reinforcement plates in the B-pillars provide additional protection in the event of a side impact and the rear engine brackets are made of high tensile but light "Trip 700" steel.
The engine in the (E83) X3 SAV is lower than in the E46 (3 series). To ensure sufficient clearance for the manifold heat shield, the left engine bracket is shorter than the right.
The hood has a side support to prevent it from moving in the event of a crash. Held in place in this way, the hood cannot jump out of its anchoring to damage the windshield.
