Both the Discovery Sport and Encore GX 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 Encore GX’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 Encore GX.
The Discovery Sport’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 Encore GX doesn’t offer a driver alert monitor.
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. Buick charges extra for Rear Cross Traffic Alert on the Encore GX and the Encore GX’s Rear Cross Traffic Alert does not include automatic braking.
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 Encore GX’s blind spot costs extra.
Both the Discovery Sport and the Encore GX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, 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 blind spot warning systems.
The Land Rover Discovery Sport weighs 832 to 1255 pounds more than the Buick Encore GX. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
