For enhanced safety, the front and rear seat shoulder belts of the Lexus NX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Alfa Romeo Tonale doesn’t offer pretensioners for its rear seat belts.
The Lexus NX 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 Tonale doesn’t offer a front passenger side knee airbag.
When descending a steep, off-road slope, the NX’s standard Downhill Assist Control allows you to creep down safely. The Tonale doesn’t offer Downhill Assist Control.
Both the NX and Tonale have rear cross-traffic warning, but the NX offers optional Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The Tonale’s Rear Cross-Path Detection doesn’t automatically brake.
Both the NX and the Tonale have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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.
The Lexus NX achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Tonale has not yet been evaluated by the IIHS for 2024.
