Compare the2024 Toyota Grand HighlanderVS 2024 Buick Enclave

For enhanced safety, the front and second-row seat shoulder belts of the Toyota Grand Highlander have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Buick Enclave doesn’t offer pretensioners for its second-row seat belts.

For enhanced safety, the front seat shoulder belts of the Toyota Grand Highlander are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Buick Enclave doesn’t offer height-adjustable front seat belts.

The Toyota Grand Highlander has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Enclave doesn’t offer knee airbags.

The Grand Highlander has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Enclave doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the Grand Highlander and Enclave have Rear Cross Traffic Alert, but the Grand Highlander Limited/Platinum has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The Enclave’s Rear Cross Traffic Alert doesn’t automatically brake.

The Grand Highlander’s 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 Enclave doesn’t offer a driver alert monitor.

Both the Grand Highlander and the Enclave 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, 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.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Toyota Grand Highlander is safer than the Enclave:

The Grand Highlander’s corrosion warranty is unlimited miles longer than the Enclave’s (unlimited vs. 100,000 miles).

Toyota pays for scheduled maintenance on the Grand Highlander for 2 years and 25000 miles. Toyota will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Buick doesn’t pay scheduled maintenance for the Enclave.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Toyota Grand Highlander higher (7 out of 10) than the Buick Enclave (6). This means the Grand Highlander produces up to 1.1 pounds less smog-producing pollutants than the Enclave every 15,000 miles.

The Grand Highlander offers an available continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Enclave doesn’t offer a CVT.

For better stopping power the Grand Highlander’s brake rotors are larger than those on the Enclave:

The Grand Highlander stops much shorter than the Enclave:

The Grand Highlander’s front to rear weight distribution is more even (52% to 48%) than the Enclave’s (57% to 43%). This gives the Grand Highlander more stable handling and braking.

The Grand Highlander Platinum AWD handles at .80 G’s, while the Enclave Avenir pulls only .75 G’s of cornering force in a Motor Trend skidpad test.

The Grand Highlander Limited AWD executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the Enclave Avenir (27.4 seconds @ .62 average G’s vs. 28.4 seconds @ .6 average G’s).

For better maneuverability, the Grand Highlander’s turning circle is .9 feet tighter than the Enclave’s (38.1 feet vs. 39 feet).

For greater off-road capability the Grand Highlander has a greater minimum ground clearance than the Enclave (8 vs. 7.5 inches), allowing the Grand Highlander to travel over rougher terrain without being stopped or damaged.

The Grand Highlander’s standard towing capacity is much higher than the Enclave’s (5000 vs. 1500 pounds).

Standard Trailer Sway Control (TSC) on the Grand Highlander uses the Enhanced Vehicle Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Enclave doesn’t offer electronic trailer sway control.

The Grand Highlander’s front and rear power windows all 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 Enclave’s passenger windows don’t close automatically.
