Compare the2024 Buick EnclaveVS 2023 Lexus GX

The Enclave has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The GX doesn’t offer front seat center airbags.

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

For better protection of the passenger compartment, the Enclave uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The GX uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Enclave and the GX 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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.

In heavy traffic or at stoplights the Enclave’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The GX doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Buick Enclave uses regular unleaded gasoline. The GX requires premium, which can cost on average about 82.8 cents more per gallon.

The Enclave 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 GX doesn’t offer a cap-less fueling system.

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

A nine-speed automatic is standard on the Buick Enclave, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the GX.

The Enclave stops shorter than the GX:

For better ride, handling and brake cooling the Enclave offers optional 20-inch wheels. The GX’s largest wheels are only 19-inches.

The Enclave has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The GX doesn’t offer vehicle monitored tire inflation.

For superior ride and handling, the Buick Enclave has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Lexus GX has a solid rear axle, with a non-independent rear suspension.

The Buick Enclave may be more efficient, handle and accelerate better because it weighs about 500 to 750 pounds less than the Lexus GX.

Unibody construction lowers the Enclave’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The GX doesn’t use unibody construction, but a body-on-frame design.

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

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

To make loading and unloading groceries and cargo easier when your hands are full, the Enclave’s power cargo door can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The GX doesn’t offer a power or hands-free opening cargo door.

The Enclave Premium/Avenir has a standard heads-up display that projects speed and tachometer readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The GX doesn’t offer a heads-up display.
