There are lots of testimonials to how much the Ecoboost V6 can tow. No magic to it really, adding turbocharging to a small engine makes it perform (and burn fuel) like a bigger one. Yes, this V6 has considerably more horsepower and torque than your 5.3 V8. There's a lot more to the equation than number of cylinders, there are 6 cylinder trucks moving over 80,000 pounds every on the roads. ;)
When it comes to towing 80,000 lbs. plus, here's also gearing and liters, among other things. Don't most highway tractors have around 12 to 16 liters of displacement that is turbocharged ?
