The EX40’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The R1S doesn’t offer pre-crash pretensioners.
Both the EX40 and R1S have child safety locks to prevent children from opening the rear doors. The EX40 Ultra 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 R1S’ 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.
The EX40 has a standard Whiplash Protection System (WHIPS), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The R1S doesn’t offer a whiplash protection system.
The EX40 has standard Post-impact braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The R1S 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.
Over 200 people are killed each year when backed over by motor vehicles. The EX40 has a standard CTA Auto Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The R1S doesn’t offer backup collision prevention brakes.
Both the EX40 and R1S have rear cross-traffic warning, but the EX40 has Braking Intervention (automatically applies the brakes) to better prevent a collision when backing near traffic. The R1S’ Rear Cross-Traffic Warning doesn’t automatically brake.
Both the EX40 and the R1S have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, 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, driver alert monitors and available around view monitors.
