The QX80 is the only Infiniti vehicle that has hardly changed its name at all. It was a QX, and a QX it remains! However, before it was the QX56 and now it’s the QX80, in keeping with Nissan’s luxury brand’s new way of naming its vehicles. Its 400-hp 5.6L V8’s 0-100 km/h time of less than eight seconds is almost supernatural. Need more room and a towing capacity of up to 8500 pounds (2656 kilos)? The QX80 is made for you!
