Safety Comparison

Both the Enclave and Sienna 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 Sienna’s 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 Sienna 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 Sienna doesn’t offer front seat center airbags.

The Enclave Premium/Avenir’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Sienna doesn’t offer a lane departure warning system.

The Enclave offers an optional Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Sienna only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

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

Warranty Comparison

The Enclave comes with a full 4-year/50,000 mile basic warranty, which covers the entire truck and includes 24 hour roadside assistance. The Sienna’s 3-year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.

Buick’s powertrain warranty covers the Enclave 1 year and 10,000 miles longer than Toyota covers the Sienna. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Sienna ends after only 5 years or 60,000 miles.

The Enclave’s corrosion warranty is 1 year longer than the Sienna’s (6 vs. 5 years).

There are over 65 percent more Buick dealers than there are Toyota dealers, which makes it much easier should you ever need service under the Enclave’s warranty.

Reliability Comparison

To reliably start during all conditions and help handle large electrical loads, the Enclave has a standard 730-amp battery. The Sienna’s 582-amp battery isn’t as powerful.

J.D. Power and Associates’ 2016 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Buick vehicles are more reliable than Toyota vehicles. J.D. Power ranks Buick third in reliability, above the industry average. With 7 more problems per 100 vehicles, Toyota is ranked fourth.

Engine Comparison

The Enclave’s 3.6 DOHC V6 produces 14 more horsepower (310 vs. 296) and 3 lbs.-ft. more torque (266 vs. 263) than the Sienna’s 3.5 DOHC V6.

Fuel Economy and Range Comparison

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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Sienna doesn’t offer an automatic engine start/stop system.

The Enclave AWD’s standard fuel tank has 1.7 gallons more fuel capacity than the Sienna (21.7 vs. 20 gallons).

Brakes and Stopping Comparison

The Enclave’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Sienna are solid, not vented.

Tires and Wheels Comparison

For better traction, the Enclave has larger tires than the Sienna (255/65R18 vs. 235/60R17).

For better ride, handling and brake cooling the Enclave has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Sienna L/LE/XLE. The Enclave’s optional 20-inch wheels are larger than the 19-inch wheels on the Sienna SE.

The Buick Enclave’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Toyota Sienna 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 Sienna doesn’t offer vehicle monitored tire inflation.

Suspension and Handling Comparison

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 Toyota Sienna has a rear torsion beam axle, with a semi-independent rear suspension.

The Enclave offers an available 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 Sienna’s suspension doesn’t offer adjustable shock absorbers.

The Enclave has 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 Sienna doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the Enclave’s wheelbase is 1.6 inches longer than on the Sienna (120.9 inches vs. 119.3 inches).

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 Sienna 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 Sienna doesn’t offer active noise cancellation.

Passenger Space Comparison

The Enclave has .7 inches more front legroom, .5 inches more front hip room, .2 inches more rear headroom and 1.3 inches more rear legroom than the Sienna.

Cargo Capacity Comparison

The Enclave’s cargo area is larger than the Sienna’s in almost every dimension:

To make loading groceries and cargo easier when your hands are full, the Enclave’s cargo door can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The Sienna doesn’t offer a hands-free gesture to open its cargo door, forcing you to put cargo down if your hands are full.

Ergonomics Comparison

The Enclave’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. The Sienna L doesn’t offer heated side mirrors.

The Enclave has standard heated front seats. Heated front seats are only available on the Sienna SE/XLE/Limited. The Enclave Premium/Avenir also has standard heated second row seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the Sienna.

Standard air-conditioned seats in the Enclave Premium/Avenir keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Sienna doesn’t offer air-conditioned seats.
