Until last year, the Infiniti QX was the luxury version of the Nissan Armada. Now, the immense Infiniti SUV has totally departed from its roots. The QX56 is propelled by a 5.6-litre V8 that delivers 400 horsepower and 413 lbs-ft of torque. It has a seven-speed automatic transmission and all-wheel drive. The towing capacity is 3,855 kilos (8,500 pounds). The seven-person version has second-row captain’s chairs while the eight-person version has a bench.
