The Range Rover’s optional driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The SQ5 doesn’t offer a driver alert monitor.
Both the Range Rover and the SQ5 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, 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 and rear cross-path warning.
The Land Rover Range Rover weighs 707 to 1437 pounds more than the Audi SQ5. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
