The X5 M’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.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the X5 M are reminded to check the back seat if they opened the rear door before starting out. The Urus doesn’t offer a back seat reminder.
The X5 M 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 Urus doesn’t offer a whiplash protection system.
The X5 M has a standard PostCrash iBrake, which automatically applies 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 X5 M has a 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 X5 M’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Urus.
The X5 M 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 and moves the vehicle back into its lane. A system to reveal vehicles in the Urus’ blind spot costs extra.
To help make backing out of a parking space safer, the X5 M has standard Cross Traffic Warning with Braking and automatically engage the brakes. Lamborghini charges extra for Rear Cross-Traffic Assist on the Urus.
The X5 M’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 X5 M and the Urus have standard driver and passenger frontal airbags, front and rear 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 around view monitors.
The BMW X5 M weighs 611 to 715 pounds more than the Lamborghini Urus. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
