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 Toyota C-HR has not been tested.
The Honda Prologue comes with a standard Surround Vision System with a rear camera washer to provide all-weather visibility, regardless of road dirt or grime, while the Toyota C-HR doesn’t offer a camera washer, requiring manual cleaning.
To help make backing out of a parking space safer, the Prologue has standard Rear Cross Traffic Alert with Rear Cross Traffic Braking, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the C-HR XSE offers Parking Support Brake.
Both the Prologue and the C-HR have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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 and available around view monitors.
The Honda Prologue weighs 566 to 951 pounds more than the Toyota C-HR. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
