For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX65 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 Audi A6 Allroad has only front height-adjustable seat belts.
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 QX65 are reminded to check the back seat if they opened the rear door before starting out. The A6 Allroad doesn’t offer a back seat reminder.
The QX65 Autograph offers an optional front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The A6 Allroad doesn’t offer front seat center airbags.
The QX65 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 and moves the vehicle back into its lane. A system to reveal vehicles in the A6 Allroad’s blind spot costs extra.
To help make backing out of a parking space safer, the QX65 has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Audi charges extra for Rear Cross-Traffic Assist on the A6 Allroad.
The QX65’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 A6 Allroad doesn’t offer a driver alert monitor.
Both the QX65 and the A6 Allroad have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available around view monitors.
