For enhanced safety, the front and middle seat shoulder belts of the Mercedes E-Class Wagon have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW X5 doesn’t offer pretensioners for the middle seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes E-Class Wagon are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X5 doesn’t offer height-adjustable seat belts.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the E-Class Wagon. But it costs extra on the X5.

Both the E-Class Wagon and the X5 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, driver alert monitors, available lane departure warning systems, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mercedes E-Class Wagon is safer than the BMW X5:

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the E-Class Wagon can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. Run-flat tires aren’t available on some tire packages on the X5.

The rear suspension of the E-Class Wagon uses air springs for a smoother, controlled ride than the X5, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The E-Class Wagon has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The E-Class Wagon’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The X5 doesn’t offer a load leveling suspension.

The E-Class Wagon’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The X5 doesn’t offer drift compensation steering.

The E 450 4MATIC Wagon handles at .90 G’s, while the X5 xDrive40i pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The E 450 4MATIC Wagon executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the X5 xDrive40i (25.7 seconds @ .73 average G’s vs. 27.3 seconds @ .67 average G’s).

For better maneuverability, the E-Class Wagon’s turning circle is 2.4 feet tighter than the X5’s (39 feet vs. 41.4 feet).
