The iX’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Model Y 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 iX are reminded to check the back seat if they opened the rear door before starting out. The Model Y doesn’t offer a back seat reminder.
The iX’s standard pretensioning seatbelts also sense rear collisions and remove slack from the front seatbelts to help protect the occupants from whiplash and other injuries. The Model Y doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the iX. But it costs extra on the Model Y.
When descending a steep, off-road slope, the iX’s standard Hill Descent Control allows you to creep down safely. The Model Y doesn’t offer Hill Descent Control.
The BMW iX’s optionalSurround View is available with washers for its front and rear cameras, ensuring crystal-clear visibility in any weather condition. Conversely, the Tesla Model Y only offers a front camera washer, which may not provide the same level of all-weather performance.
The iX has standard BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model Y 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 iX and the Model Y have standard driver and passenger frontal airbags, front 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, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
The BMW iX weighs 1169 to 1665 pounds more than the Tesla Model Y. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
