2016 Cadillac XTS

Safety Comparison

The 7 Series’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The XTS doesn’t offer pre-crash pretensioners.

An active infrared night vision system optional on the 7 Series helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then projects the image on the windshield, near the driver’s line of sight. The XTS doesn’t offer a night vision system.

The 7 Series’ 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 XTS doesn’t offer a driver alert monitor.

Both the 7 Series and the XTS have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rear parking sensors, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty Comparison

The 7 Series’ corrosion warranty is 6 years longer than the XTS’ (12 vs. 6 years).

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the 7 Series has a standard 180-amp alternator (250-amp - 7 Series optional). The XTS’ 170-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the 7 Series has a standard 950-amp battery. The XTS’ 660-amp battery isn’t as powerful.

The battery on the 7 Series is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the 7 Series’ battery 20 to 30 degrees cooler, its life is increased by years. The XTS’ battery is in the hot engine compartment.

J.D. Power and Associates’ 2015 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 6th in initial quality, above the industry average. With 23 more problems per 100 vehicles, Cadillac is ranked 21st, below the industry average.

Fuel Economy and Range Comparison

Regenerative brakes improve the 7 Series’ fuel efficiency by converting inertia back into energy instead of wasting it. The XTS doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the 7 Series’ 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 XTS doesn’t offer an automatic engine start/stop system.

The 7 Series has 1.6 gallons more fuel capacity than the XTS FWD’s standard fuel tank (20.6 vs. 19 gallons), for longer range between fill-ups.

Brakes and Stopping Comparison

Tires and Wheels Comparison

For better ride, handling and brake cooling the 7 Series offers optional 21-inch wheels. The XTS’ largest wheels are only 20-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 7 Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The XTS doesn’t offer run-flat tires.

Suspension and Handling Comparison

The 7 Series has standard front and rear stabilizer bars, which help keep the 7 Series flat and controlled during cornering. The XTS’ suspension doesn’t offer a rear stabilizer bar.

The 7 Series offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The XTS doesn’t offer an active sway bar system.

The front and rear suspension of the 7 Series uses air springs for a smoother, controlled ride than the XTS, which uses coil springs in front. Air springs maintain proper ride height and ride more smoothly.

The 7 Series offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Cadillac doesn’t offer an active suspension on the XTS.

For a smoother ride and more stable handling, the 7 Series’ wheelbase is 14.7 inches longer than on the XTS (126.4 inches vs. 111.7 inches).

For better handling and stability, the track (width between the wheels) on the 7 Series is 1.7 inches wider in the front and 3 inches wider in the rear than on the XTS.

The 7 Series’ front to rear weight distribution is more even (51.6% to 48.4%) than the XTS’ (57.8% to 42.2%). This gives the 7 Series more stable handling and braking.

The 750i xDrive handles at .88 G’s, while the XTS AWD pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The 750i xDrive executes Motor Trend’s “Figure Eight” maneuver 2.2 seconds quicker than the XTS AWD (25.4 seconds @ .75 average G’s vs. 27.6 seconds @ .63 average G’s).

Chassis Comparison

The front grille of the 7 Series uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The XTS doesn’t offer active grille shutters.

As tested by Car and Driver while at idle, the interior of the 750i xDrive is quieter than the XTS (38 vs. 41 dB).

Passenger Space Comparison

The 7 Series has 1.8 inches more front headroom, 1.3 inches more front shoulder room, 1.1 inches more rear headroom, 4.4 inches more rear legroom and 1.4 inches more rear shoulder room than the XTS.

For enhanced passenger comfort on long trips the 7 Series’ available rear seats recline. The XTS’ rear seats don’t recline.

Cargo Capacity Comparison

A low lift-over trunk design makes loading and unloading the 7 Series easier. The 7 Series’ trunk lift-over height is 27.2 inches, while the XTS’ liftover is 30 inches.

To make loading and unloading groceries and cargo easier when your hands are full, the 7 Series’ trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The 7 Series also has a standard power trunk, which opens and closes automatically by pressing a button or just by kicking your foot under the back bumper. The XTS doesn’t offer a power or hands-free opening trunk.

Ergonomics Comparison

The 7 Series’ standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the XTS.

If the windows are left down on the 7 Series the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the XTS can only raise the windows from inside the vehicle, with the ignition on.

The 7 Series 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 XTS doesn’t offer a locking fuel door.

The 7 Series’ 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 XTS’ standard manually variable intermittent wipers have to be constantly adjusted.

Optional air-conditioned front and rear seats keep the 7 Series’ passengers comfortable and take the sting out of hot leather in summer. The XTS doesn’t offer air-conditioned seats in the rear.
