The 2010 Infiniti QX's size and stance speak of the power within. The heavy-duty, reinforced 5.6-litre V8 delivers. The most formidable engine Infiniti has ever built, this aluminum-alloy, dual overhead cam, 32-valve powerhouse generates 320 horsepower and 393 lb-ft of torque, for surprisingly swift, steady acceleration. And an impressive towing capacity of up to 4,037 kg (8,900 lbs).
