For enhanced safety, the front seat shoulder belts of the Volvo V60 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes GLA doesn’t offer height-adjustable seat belts.
Both the V60 and GLA have child safety locks to prevent children from opening the rear doors. The V60 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 GLA’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.
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 V60 are reminded to check the back seat if they opened the rear door before starting out. The GLA doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The V60 has standard CTA Auto Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLA doesn’t offer automatic braking for stationary objects directly to the rear.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the V60. But it costs extra on the GLA.
The V60’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GLA.
Both the V60 and the GLA have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
The Volvo V60 weighs 1001 to 1111 pounds more than the Mercedes GLA. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
