2015 Cadillac SRX

Safety Comparison

The X3 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The SRX only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the X3 and the SRX 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 and available all wheel drive.

Warranty Comparison

The X3’s corrosion warranty is 6 years longer than the SRX’s (12 vs. 6 years).

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the X3 has a standard 210-amp alternator (180-amp - X3 diesel). The SRX’s 150-amp alternator isn’t as powerful.

J.D. Power and Associates rated the X3 second among compact premium suvs in their 2013 Initial Quality Study. The SRX isn’t in the top three in its category.

J.D. Power and Associates’ 2014 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Cadillac vehicles. J.D. Power ranks BMW 8th in initial quality, above the industry average. With 7 more problems per 100 vehicles, Cadillac is ranked 13th.

Engine Comparison

The X3 xDrive35i’s standard 3.0 turbo 6 cyl. produces 35 lbs.-ft. more torque (300 vs. 265) than the SRX’s 3.6 DOHC V6.

The X3’s 2.0 turbo diesel produces 15 lbs.-ft. more torque (280 vs. 265) than the SRX’s 3.6 DOHC V6.

Fuel Economy and Range Comparison

On the EPA test cycle the X3 xDrive28d gets better fuel mileage than the SRX 4 (27 city/34 hwy vs. 16 city/23 hwy).

On the EPA test cycle the X3 gets better fuel mileage than the SRX:

Regenerative brakes improve the X3’s fuel efficiency by converting inertia back into energy instead of wasting it. The SRX doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the X3’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The SRX doesn’t offer an automatic engine start/stop system.

Tires and Wheels Comparison

For better traction, the X3 has larger standard tires than the SRX (245/50R18 vs. 235/65R18). The X3’s optional tires are larger than the largest tires available on the SRX (F:245/45R19 & R:275/40R19 vs. 235/65R18).

The X3’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 SRX’s standard 65 series tires. The X3’s optional 245/40R20 front and 275/35R20 rear tires have a lower 40 series front and 35 series rear profile than the SRX’s optional 55 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X3 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The SRX doesn’t offer run-flat tires.

Suspension and Handling Comparison

The X3 has standard front and rear gas-charged shocks for better control over choppy roads. The SRX’s suspension doesn’t offer gas-charged shocks.

The X3’s front to rear weight distribution is more even (50.1% to 49.9%) than the SRX’s (57% to 43%). This gives the X3 more stable handling and braking.

For better maneuverability, the X3’s turning circle is 1.3 feet tighter than the SRX’s (39 feet vs. 40.3 feet).

Chassis Comparison

The BMW X3 may be more efficient, handle and accelerate better because it weighs about 200 to 250 pounds less than the Cadillac SRX.

The X3 is 6.9 inches shorter than the SRX, making the X3 easier to handle, maneuver and park in tight spaces.

Passenger Space Comparison

The X3 has 1 inch more front headroom, .1 inches more front shoulder room, .7 inches more rear headroom, .5 inches more rear legroom and 1.1 inches more rear shoulder room than the SRX.

Cargo Capacity Comparison

The X3 has a larger cargo area with its rear seat folded than the SRX with its rear seat folded (63.3 vs. 61.1 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the X3 easier. The X3’s cargo hatch lift-over height is 27.8 inches, while the SRX’s liftover is 30.1 inches.

To make loading groceries and cargo easier when your hands are full, the X3’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The SRX doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Ergonomics Comparison

The X3 offers an optional heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The SRX doesn’t offer a heads-up display.

The X3 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The SRX doesn’t offer a locking fuel door.

The X3’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The SRX’s standard manually variable intermittent wipers have to be constantly adjusted.

The X3’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 SRX doesn’t offer an automated parking system.

Recommendations Comparison

J.D. Power and Associates rated the X3 second among compact premium suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The SRX isn’t in the top three in its category.
