The Cullinan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Urus doesn’t offer pre-crash pretensioners.
The Cullinan has standard PostCrash, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Urus doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The Cullinan has standard Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Urus doesn’t offer automatic braking for stationary objects directly to the rear.
The Cullinan’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the Urus.
The Cullinan has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Urus’ blind spot costs extra.
To help make backing out of a parking space safer, the Cullinan has standard Cross Traffic Warning, helping the driver avoid collisions. Lamborghini charges extra for Rear Cross-Traffic Assist on the Urus.
The Cullinan’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 Urus doesn’t offer a driver alert monitor.
Both the Cullinan and the Urus have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, rearview cameras and available night vision systems.
The Rolls-Royce Cullinan weighs 1457 to 1574 pounds more than the Lamborghini Urus. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
