My previous review was the Chevy Silverado 6.4L towing, this time it is the 2016 5.3L Chev Silverado Extreme Tow on test. Lets see how they compare especially as the 5.30L is by far the most popular engine option. Actually this isn’t an exact comparison between the 2 engine sizes as the 5.3L is on the notorious Ike Gauntlet, while the 6.4L was on a 100 mile test run to establish MPG figure only. But there is another Ike Gauntlet extreme tow review of the Silverado with the 6.4L engine so you can directly compare the two on the same road.
On a climb like this it is to be expected the MPG figure wont be high, especially as going up the engine is working hard and from what I could see the tacho was sitting on 4500 or more RPM. At 60 mph I guess the auto would have been locked in 6th gear The all up trailer weight was 9,000lbs, 2000lbs below its maximum tow capacity. this model also has a maximum payload of 2,160lbs, and while the guys did put some weight onto the deck, I am not sure how much. The 5.3L V8 engine in this review puts out 255hp, 383 ft lbs of torque and is matched to the 8 speed auto with an axle ratio of 3.73, rear wheel drive only. Very much a popular Silverado set up. Also part of this test was going back down the Ike Gauntlet, and those who do heavy towing know how important engine braking ability is, and the need to avoid using the brakes as much as possible on a long steep hill like this.
This time the FTL guys showed how they score a test like this at the 6 min 50 second mark and while it is simple enough, is also quite fair I thought. Check it and find out how this Chevy scored.
