The GLC Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Tiguan doesn’t offer pre-crash pretensioners.
The GLC Coupe has standard NECK-PRO front head restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO front head restraints system moves the headrests forward to prevent neck and spine injuries. The Tiguan doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the GLC Coupe. 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 GLC Coupe has Car-to-X Communication, 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 or other vehicles.
The GLC Coupe’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 GLC Coupe and the Tiguan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, front seat center airbag, 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, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.
The Insurance Institute for Highway Safety does 40 MPH moderate front offset crash tests on new cars. In this updated test, results indicate that the GLC Coupe is much safer than the Tiguan:

The Mercedes GLC Coupe achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2026 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated moderate overlap front crash test, updated side impact crash test, headlight evaluations, pedestrian crash prevention testing, and vehicle-to-vehicle crash prevention testing. The Tiguan has not yet been fully evaluated by the IIHS for 2026.
