Over 200 people are killed each year when backed over by motor vehicles. The X4 offers optional Active Park Distance Control which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Allroad doesn’t offer backup collision prevention brakes.

The X4’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Allroad doesn’t offer a driver alert monitor.

Both the X4 and the Allroad have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.


BMW pays for scheduled maintenance on the X4 for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the Allroad.

There are over 13 percent more BMW dealers than there are Audi dealers, which makes it easier should you ever need service under the X4’s warranty.

Tires and Wheels

The X4 M40i’s optional 245/40R21 front and 275/35R21 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the Allroad’s 45 series tires.

For better ride, handling and brake cooling the X4 has standard 19-inch wheels. Only 18-inch wheels are available on the Allroad. The X4 M40i offers optional 21-inch wheels.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X4 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Allroad doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the X4’s wheelbase is 1.9 inches longer than on the Allroad (112.8 inches vs. 110.9 inches).

For better handling and stability, the average track (width between the wheels) on the X4 is 1.3 inches wider in the front and 3.5 inches wider in the rear than the track on the Allroad.

The X4 M40i handles at .89 G’s, while the Allroad Premium Plus pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The X4 M40i executes Motor Trend’s “Figure Eight” maneuver quicker than the Allroad Premium Plus (25.6 seconds @ .73 average G’s vs. 26.3 seconds @ .69 average G’s).

For greater off-road capability the X4 has a 1.5 inches greater minimum ground clearance than the Allroad (8 vs. 6.5 inches), allowing the X4 to travel over rougher terrain without being stopped or damaged.


The design of the BMW X4 amounts to more than styling. The X4 has an aerodynamic coefficient of drag of .3 Cd. That is lower than the Allroad (.32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the X4 get better fuel mileage.

Passenger Space

The X4 has 5.8 cubic feet more passenger volume than the Allroad (97.8 vs. 92).

The X4 has 1.6 inches more front shoulder room and 1.5 inches more rear shoulder room than the Allroad.


The Allroad’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The X4’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

When the X4 is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Allroad’s mirror doesn’t automatically adjust for backing.

The X4’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Allroad doesn’t offer an automated parking system.
