The XT6’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Envision doesn’t offer pre-crash pretensioners.
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 XT6 are reminded to check the back seat if they opened the rear door before starting out. The Envision doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The XT6 offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Envision doesn’t offer backup collision prevention brakes.
A passive infrared night vision system optional on the XT6 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Envision doesn’t offer a night vision system.
Both the XT6 and the Envision have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive and around view monitors.
The XT6’s 3.6 DOHC V6 produces 113 more horsepower (310 vs. 197) and 79 lbs.-ft. more torque (271 vs. 192) than the Envision’s standard 2.5 DOHC 4-cyl. The XT6’s 3.6 DOHC V6 produces 58 more horsepower (310 vs. 252) than the Envision Premium’s standard 2.0 turbo 4-cyl.
An engine control system that can shut down half of the engine’s cylinders helps improve the XT6’s fuel efficiency. The Envision doesn’t offer a system that can shut down part of the engine.

The XT6 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 Envision doesn’t offer a cap-less fueling system.
The XT6’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Envision are solid, not vented.
For better traction, the XT6 has larger standard tires than the Envision (235/55R20 vs. 225/60R18). The XT6Sport’s optional tires are larger than the largest tires available on the Envision (265/45R21 vs. 235/50R19).
The XT6’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Envision’s standard 60 series tires. The XT6Sport’s optional tires have a lower 45 series profile than the Envision Premium’s 50 series tires.
For better ride, handling and brake cooling the XT6 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Envision. The XT6Sport’s optional 21-inch wheels are larger than the 19-inch wheels on the Envision Premium.
The Cadillac XT6’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Buick Envision only has 5 wheel lugs per wheel.
The XT6 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 Envision’s suspension doesn’t offer adjustable shock absorbers.
The XT6 has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Envision doesn’t offer variable-assist power steering.
For a smoother ride and more stable handling, the XT6’s wheelbase is 4.4 inches longer than on the Envision (112.7 inches vs. 108.3 inches).
For better handling and stability, the track (width between the wheels) on the XT6 is 4.4 inches wider in the front and 4.2 inches wider in the rear than on the Envision.

Maximum trailer towing in the Buick Envision is limited to 1500 pounds. The XT6 offers up to a 4000 lbs. towing capacity.
J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Buick. J.D. Power ranks Cadillac third in service department satisfaction. With a 23% lower rating, Buick is ranked 8th.
The XT6’s front power windows open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Envision’s front passenger window doesn’t close automatically.
On a hot day the XT6’s driver can lower all the windows from a distance using the keyless remote. The driver of the Envision can only operate the windows from inside the vehicle, with the ignition on.
The XT6’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 Envision’s standard manually variable intermittent wipers have to be constantly adjusted.
To help drivers avoid possible obstacles, the XT6 has standard cornering lights to illuminate around corners when the turn signals are activated. The Envision doesn’t offer cornering lights.
The XT6 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel is only available on the Envision Essence/Premium.
