( http://www.TFLcar.com ) The 2012 Infiniti QX56 is a big, powerful and luxurious SUV built to haul people and a lot of their stuff. In fact this vehicle with 400 HP and over 400 lb-ft of torque has a towing capacity that exceeds 8000 pounds. But what does that mean in the real world where the tires hit the road. We decided to find out by putting the Infiniti QX56 to the TFLcar towing test. We hooked up a 5500 pound boat to the back of the Infiniti QX56 to see how fast it would accelerate from 0-60 MPH @ 1 mile above sea level. And of course just to see compare the difference we also tried the same 0-60 MPH run with our the boat. How did the big Infiniti QX56 fare? Check out this video to find out.
