To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Discovery. But it costs extra on the Model Y.
When descending a steep, off-road slope, the Discovery’s standard Hill Descent Control allows you to creep down safely. The Model Y doesn’t offer Hill Descent Control.
The Discovery has a standard 3D Surround Camera to allow the driver to see objects all around the vehicle on a screen. The Model Y 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.
The Land Rover Discovery’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Tesla Model Y does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
The Discovery has standard InControl, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in 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 Discovery and the Model Y have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, rear cross-path warning and driver alert monitors.
The Land Rover Discovery weighs 447 to 991 pounds more than the Tesla Model Y. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
