For enhanced safety, the front and rear seat shoulder belts of the Honda Prologue 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 Alfa Romeo Tonale doesn’t offer pretensioners for its rear seat belts.
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 Prologue are reminded to check the back seat if they opened the rear door before starting out. The Tonale doesn’t offer a back seat reminder.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Honda Prologue achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Alfa Romeo Tonale has not been tested.
Both the Prologue and Tonale have rear cross-traffic warning, but the Prologue has Rear Cross Traffic Braking (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 Prologue and the Tonale have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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 and available around view monitors.
The Honda Prologue weighs 799 to 1140 pounds more than the Alfa Romeo Tonale. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
