Both the Range Rover and the XC60 have standard driver and passenger frontal airbags, front side-impact 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, rearview cameras, available blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
The Land Rover Range Rover weighs 921 to 1821 pounds more than the Volvo XC60. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
