The EX90’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Grand Highlander 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 EX90 are reminded to check the back seat when a sensor determines the back seat is occupied. The Grand Highlander doesn’t offer a back seat reminder.
The Volvo EX90 (except 6-Passenger) offers an optional built in child booster seat. It’s more crash worthy than an added child seat because of its direct attachment to the seat. Toyota doesn’t offer the convenience and security of a built-in child booster seat in the Grand Highlander. Their owners must carry a heavy booster seat in and out of the vehicle; EX90 owners can just fold their built-in child seat up or down.
The Volvo EX90 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Grand Highlander doesn’t offer a front passenger side knee airbag.
The EX90 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 Grand Highlander doesn’t offer front seat center airbags.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the EX90. But it costs extra on the Grand Highlander.
To help make backing out of a parking space safer, the EX90 has standard Cross Traffic Alert with Braking Intervention, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the Grand Highlander Limited/Platinum offers Parking Support Brake.
Both the EX90 and the Grand Highlander have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
The Volvo EX90 weighs 1290 to 1912 pounds more than the Toyota Grand Highlander. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
