Both the Discovery Sport and Rav4 have child safety locks to prevent children from opening the rear doors. The Discovery Sport has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Rav4’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Discovery Sport. But it costs extra on the Rav4.
The Discovery Sport 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. A system to reveal vehicles in the Rav4’s blind spot costs extra.
To help make backing out of a parking space safer, the Discovery Sport has standard Rear Traffic Monitor and Rear Traffic Braking automatically engages the brakes to help avoid a collision. Toyota charges extra for Rear Cross Traffic Alert on the Rav4.
Both the Discovery Sport and the Rav4 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.
The Land Rover Discovery Sport weighs 415 to 900 pounds more than the Toyota Rav4. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
