The Durango SRT has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Stelvio Quadrifoglio doesn’t offer a whiplash protection system.
Both the Durango SRT and the Stelvio Quadrifoglio have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, available crash mitigating brakes and lane departure warning systems.
The Dodge Durango SRT weighs 1267 pounds more than the Alfa Romeo Stelvio Quadrifoglio. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
