Safety Comparison

For enhanced safety, the Buick Enclave’s middle seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Lexus RX Series doesn’t offer comfort guides on its middle seat belts.

Both the Enclave and RX Series have child safety locks to prevent children from opening the rear doors. The Enclave has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The RX Series’ child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

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 Enclave are reminded to check the back seat if they opened the rear door before starting out. The RX Series doesn’t offer a back seat reminder.

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 RX Series doesn’t offer front seat center airbags.

Both the Enclave and the RX Series have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front-wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty Comparison

Buick pays for scheduled maintenance on the Enclave for 2 years and 24,000 miles. Buick will pay for oil changes, lubrication and any other required maintenance (up to 2 oil changes). Lexus only pays for the first scheduled maintenance visit on the RX Series.

There are almost 9 times as many Buick dealers as there are Lexus dealers, which makes it much easier should you ever need service under the Enclave’s warranty.

Reliability Comparison

J.D. Power and Associates’ 2017 Initial Quality Study of new car owners surveyed provide the statistics that show that Buick vehicles are better in initial quality than Lexus vehicles. J.D. Power ranks Buick 13th in initial quality, above the industry average. With 3 more problems per 100 vehicles, Lexus is ranked 15th, below the industry average.

Engine Comparison

The Enclave’s 3.6 DOHC V6 produces 15 more horsepower (310 vs. 295) than the RX 350’s standard 3.5 DOHC V6. The Enclave’s 3.6 DOHC V6 produces 2 more horsepower (310 vs. 308) than the RX 450h’s standard 3.5 DOHC V6 hybrid.

Fuel Economy and Range Comparison

To lower fuel costs and make buying fuel easier, the Buick Enclave uses regular unleaded gasoline. The RX 450h requires premium, which can cost 20 to 55 cents more per gallon.

The Enclave FWD’s standard fuel tank has 2.2 gallons more fuel capacity than the RX Series Hybrid’s standard fuel tank (19.4 vs. 17.2 gallons), for longer range between fill-ups. The Enclave AWD’s standard fuel tank has 2.5 gallons more fuel capacity than the RX Series’ standard fuel tank (21.7 vs. 19.2 gallons).

Tires and Wheels Comparison

For better traction, the Enclave has larger tires than the RX Series (255/65R18 vs. 235/65R18).

The Buick Enclave’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Lexus RX Series only has 5 wheel lugs per wheel.

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 RX Series doesn’t offer vehicle monitored tire inflation.

Suspension and Handling Comparison

For a smoother ride and more stable handling, the Enclave’s wheelbase is 11.1 inches longer than on the RX Series (120.9 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the Enclave is 2.9 inches wider in the front and 3 inches wider in the rear than on the RX Series.

Chassis Comparison

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 RX Series 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 RX Series doesn’t offer active noise cancellation.

Passenger Space Comparison

The Enclave has standard seating for 7 passengers; the RX Series can only carry 5.

The Enclave has 1.6 inches more front headroom, 2.5 inches more front hip room, 4.6 inches more front shoulder room, 1.7 inches more rear headroom, .9 inches more rear legroom, 1.7 inches more rear hip room and 4.1 inches more rear shoulder room than the RX Series.
