The X5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Macan doesn’t offer pre-crash pretensioners.
Over 200 people are killed each year when backed over by motor vehicles. The X5 offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Macan doesn’t offer backup collision prevention brakes.
The X5 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 Macan’s blind spot costs extra.
To help make backing out of a parking space safer, the X5’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Macan doesn’t offer a cross-path warning system.
The X5’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 Macan doesn’t offer a driver alert monitor.
Both the X5 and the Macan have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, post-collision automatic braking systems, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive and around view monitors.
The BMW X5 weighs 428 to 1109 pounds more than the Porsche Macan. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the X5 the rating of “Top Pick” for 2021, a rating granted to only 145 vehicles tested by the IIHS. The Macan has not been tested, yet.
