The X4 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 154 more horsepower (382 vs. 228) and 111 lbs.-ft. more torque (369 vs. 258) than the Q3’s 2.0 turbo 4-cylinder.

Regenerative brakes improve the X4’s fuel efficiency by converting inertia back into energy instead of wasting it. The Q3 doesn’t offer a regenerative braking system.

The X4 has 1.3 gallons more fuel capacity than the Q3 (17.2 vs. 15.9 gallons), for longer range between fill-ups.

For better stopping power the X4 M40i’s brake rotors are larger than those on the Q3:

The X4 stops much shorter than the Q3:

For better traction, the X4 has larger standard tires than the Q3 (245/50R19 vs. 235/55R18).

The X4’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Q3’s standard 55 series tires. The X4’s optional 275/35R21 rear tires have a lower 35 series profile than the Q3’s optional 40 series tires.

For better ride, handling and brake cooling the X4 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Q3. The X4’s optional 21-inch wheels are larger than the 20-inch wheels optional on the Q3.

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 Q3 doesn’t offer run-flat tires.

The X4 offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Q3’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the X4’s wheelbase is 7.3 inches longer than on the Q3 (112.8 inches vs. 105.5 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 3.3 inches wider in the rear than the track on the Q3.

The X4 M40i handles at .89 G’s, while the Q3 pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The X4 M40i executes Motor Trend’s “Figure Eight” maneuver 2.8 seconds quicker than the Q3 (25.6 seconds @ .73 average G’s vs. 28.4 seconds @ .65 average G’s).

For greater off-road capability the X4 has a 2.5 inches greater minimum ground clearance than the Q3 (8 vs. 5.5 inches), allowing the X4 to travel over rougher terrain without being stopped or damaged.

The front grille of the X4 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Q3 doesn’t offer active grille shutters.

The X4 has 13.8 cubic feet more passenger volume than the Q3 (97.8 vs. 84).

The X4 has .7 inches more front headroom, .7 inches more front legroom, .8 inches more front shoulder room and .9 inches more rear shoulder room than the Q3.

The X4 has a larger cargo volume with its rear seat folded than the Q3 with its rear seat folded (50.5 vs. 48 cubic feet).

Pulling a handle automatically lowers the X4’s rear seats, to make changing between passengers and cargo easier. The Q3 doesn’t offer automatic folding seats.

The engine in the X4 is mounted longitudinally (North-South), instead of sideways, as in the Q3. This makes it easier to service and maintain, because the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Audi. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 1% lower rating, Audi is ranked 8th.

The X4 offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Q3 doesn’t offer a remote starting system.

The Q3 Premium Plus’ cornering lamps activate a lamp on the front corner when the turn signal is activated. The X4’s standard 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 Q3’s mirror doesn’t automatically adjust for backing.

Both the X4 and the Q3 offer available heated front seats. The X4 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Q3.

Optional air-conditioned seats in the X4 keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Q3 doesn’t offer air-conditioned seats.
