Safety Comparison

For enhanced safety, the front and rear (child comfort guides) seat shoulder belts of the Cadillac SRX 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 X3 doesn’t offer height-adjustable seat belts.

Both the SRX and X3 have child safety locks to prevent children from opening the rear doors. The SRX has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The X3’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

Over 200 people are killed each year when backed over by motor vehicles. The SRX offers optional Rear Automatic Braking which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The X3 doesn’t offer backup collision prevention brakes.

To help make backing safer, the SRX’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The X3 doesn’t offer a cross-path warning system.

Both the SRX and the X3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, available all-wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and rearview cameras.

Warranty Comparison

Cadillac’s powertrain warranty covers the SRX 2 years and 20,000 miles longer than BMW covers the X3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X3 ends after only 4 years or 50,000 miles.

There are over 4 times as many Cadillac dealers as there are BMW dealers, which makes it much easier should you ever need service under the SRX’s warranty.

Reliability Comparison

J.D. Power and Associates’ 2015 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Cadillac vehicles are more reliable than BMW vehicles. J.D. Power ranks Cadillac fourth in reliability, above the industry average. With 32 more problems per 100 vehicles, BMW is ranked 18th.

Engine Comparison

The SRX’s 3.6 DOHC V6 produces 68 more horsepower (308 vs. 240) and 5 lbs.-ft. more torque (265 vs. 260) than the X3 s/xDrive28i’s standard 2.0 turbo 4 cyl. The SRX’s 3.6 DOHC V6 produces 8 more horsepower (308 vs. 300) than the X3 xDrive35i’s standard 3.0 turbo 6 cyl.

Fuel Economy and Range Comparison

To lower fuel costs and make buying fuel easier, the Cadillac SRX uses regular unleaded gasoline. The X3 requires premium, which can cost 20 to 55 cents more per gallon.

The SRX has 3.3 gallons more fuel capacity than the X3 (21 vs. 17.7 gallons), for longer range between fill-ups.

Brakes and Stopping Comparison

For better stopping power the SRX’s front brake rotors are larger than those on the X3:



Front Rotors

13.6 inches

12.9 inches

Tires and Wheels Comparison

The Cadillac SRX’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The BMW X3 only has 5 wheel lugs per wheel.

Chassis Comparison

The SRX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The X3 doesn’t offer active noise cancellation.

Passenger Space Comparison

For enhanced passenger comfort on long trips the SRX’s rear seats recline. The X3’s rear seats don’t recline.

Cargo Capacity Comparison

The SRX has a much larger cargo area than the X3 with its rear seat up (29.8 vs. 27.6 cubic feet).

The SRX’s cargo area is larger than the X3’s in almost every dimension:

Ergonomics Comparison

The SRX 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 X3 doesn’t offer a remote starting system.

The SRX’s optional easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The X3 doesn’t offer an easy entry system.

The SRX’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The X3 has neither an oil pressure gauge nor a temperature gauge.

To improve rear visibility by keeping the rear window clear, the SRX has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the X3 only has an intermittent setting, so in a hard rain visibility isn’t as good.

Optional air conditioned seats in the SRX keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The X3 doesn’t offer air conditioned seats.

The SRX has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the X3.

Recommendations Comparison

The Cadillac SRX outsold the BMW X3 by over two to one during the 2015 model year.
