For enhanced safety, the front and rear (child comfort guides) seat shoulder belts of the Cadillac XT5 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 X6 doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the XT5 are reminded to check the back seat if they opened the rear door before starting out. The X6 doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The XT5 offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The X6 doesn’t offer backup collision prevention brakes.

To help make backing safer, the XT5’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 X6 doesn’t offer a cross-path warning system.

Both the XT5 and the X6 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the XT5 the rating of “Top Pick” for 2017, a rating granted to only 154 vehicles tested by the IIHS. The X6 has not been tested, yet.


Cadillac’s powertrain warranty covers the XT5 2 years and 20,000 miles longer than BMW covers the X6. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X6 ends after only 4 years or 50,000 miles.

There are almost 3 times as many Cadillac dealers as there are BMW dealers, which makes it much easier should you ever need service under the XT5’s warranty.


The XT5’s 3.6 DOHC V6 produces 8 more horsepower (310 vs. 302) than the X6 s/xDrive35i’s standard 3.0 turbo 6 cyl.

An engine control system that can shut down half of the engine’s cylinders helps improve the XT5’s fuel efficiency. The X6 doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Cadillac XT5 uses regular unleaded gasoline. The X6 requires premium, which can cost 20 to 55 cents more per gallon.

The XT5 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The X6 doesn’t offer a cap-less fueling system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac XT5 higher (6 out of 10) than the BMW X6 (3). This means the XT5 produces up to 23.4 pounds less smog-producing pollutants than the X6 every 15,000 miles.

Tires and Wheels

The Cadillac XT5’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The BMW X6 only has 5 wheel lugs per wheel.

Suspension and Handling

For better maneuverability, the XT5’s turning circle is 3.3 feet tighter than the X6’s (38.7 feet vs. 42 feet). The XT5 w/20” wheels’ turning circle is 3 feet tighter than the X6’s (39 feet vs. 42 feet).


The Cadillac XT5 may be more efficient, handle and accelerate better because it weighs about 600 to 700 pounds less than the BMW X6.

The XT5 is 4.3 inches shorter than the X6, making the XT5 easier to handle, maneuver and park in tight spaces.

Passenger Space

The XT5 has .9 inches more front legroom and 3.9 inches more rear legroom than the X6.

For enhanced passenger comfort on long trips the XT5’s rear seats recline. The X6’s rear seats don’t recline.

Cargo Capacity

The XT5 has a much larger cargo volume with its rear seat up than the X6 with its rear seat up (30 vs. 26.6 cubic feet). The XT5 has a much larger cargo volume with its rear seat folded than the X6 with its rear seat folded (63 vs. 59.7 cubic feet).

Pressing a switch automatically lowers the XT5’s rear seats, to make changing between passengers and cargo easier. The X6 doesn’t offer automatic folding seats.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than BMW. J.D. Power ranks Cadillac third in service department satisfaction. With a 14% lower rating, BMW is ranked 8th.


The XT5 has a standard 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 X6 doesn’t offer a remote starting system.

The XT5’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 X6 does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the XT5 has a standard rear wiper. The X6 doesn’t offer a rear wiper.

Economic Advantages

Insurance will cost less for the XT5 owner. The Complete Car Cost Guide estimates that insurance for the XT5 will cost $3760 to $6890 less than the X6 over a five-year period.

According to The Car Book by Jack Gillis, the XT5 is less expensive to operate than the X6 because typical repairs cost much less on the XT5 than the X6, including $641 less for a water pump, $693 less for a muffler, $129 less for front brake pads, $235 less for a starter, $15 less for fuel injection, $415 less for a fuel pump, $323 less for front struts and $1486 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Cadillac XT5 will be $18861 to $21611 less than for the BMW X6.


The Cadillac XT5 outsold the BMW X6 by almost 9 to one during 2018.
