The RXL has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The Model X doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The RXL offers optional Auto Brake that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Model X doesn’t offer backup collision prevention brakes.
The RXL offers an optional Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Model X only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
To help make backing out of a parking space safer, the RXL’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 Model X doesn’t offer a cross-path warning system.
The RXL’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 Model X doesn’t offer a driver alert monitor.
The RXL has standard Safety Connect®, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model X doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the RXL and the Model X have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, 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, lane departure warning systems, blind spot warning systems, rearview cameras and available all wheel drive.
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 “Acceptable” rating, the Insurance Institute for Highway Safety grants the RXL the rating of “Top Pick” for 2021, a rating granted to only 128 vehicles tested by the IIHS. The Model X has not been tested, yet.
