These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection.

The QX55 has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Q5 Sportback doesn’t offer a CVT.

For better traction, the QX55 has larger tires than the Q5 Sportback (255/45R20 vs. 235/55R19).

The QX55’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Q5 Sportback’s standard 55 series tires.

For better ride, handling and brake cooling the QX55 has standard 20-inch wheels. Smaller 19-inch wheels are standard on the Q5 Sportback.

The QX55 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Q5 Sportback doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX55 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Q5 Sportback doesn’t offer run-flat tires.

The QX55’s standard Entry/Exit Assist raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Q5 Sportback.

To improve rear visibility by keeping the rear window clear, the QX55 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Q5 Sportback only has an intermittent setting, so in a hard rain visibility isn’t as good.

The Q5 Sportback’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The QX55 Essential/Sensory’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.
