Both the new Q5 and Tiguan have child safety locks to prevent children from opening the rear doors. The new Q5 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Tiguan’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the new Q5. But it costs extra on the Tiguan.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The new Q5 has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Tiguan doesn’t offer a system that can receive automated systems from infrastructure.
The new Q5’s 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 Tiguan doesn’t offer a driver alert monitor.
Both the new Q5 and the Tiguan have standard driver and passenger frontal airbags, front and rear side-impact airbags, front seat center airbag, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
The Audi new Q5 weighs 443 to 681 pounds more than the Volkswagen Tiguan. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
