Ike Gauntlet 2.0: 2014 Chevrolet Silverado 6.2L – Extreme Towing Test

Welcome to is Episode 3 of the Ike Gauntlet 2.0.  Why the “2.0”?  We are using a new trailer and more weight.  Total load of 8,000 lbs from the previous series was not high enough to slow most trucks down.  The 2014 Chevrolet Silverado 6.2L CrewCab 4×4 LTZ is next to challenge this extreme towing test.

This Silverado is equipped with the big-boy 6.2-liter EcoTec3 V8 paired with a 6-speed automatic transmission.  It has the displacement to produce 420 horsepower at 5,600 rpm and 460 lb-ft of torque at 4,100 rpm.  This truck’s wheelbase is 153 inches and it’s rated at 7,200 lbs GVWR, 1,300 lbs of payload or a maximum 11,800 lbs of towing capacity.  This truck had the Maximum Towing package with a low 3.73 rear axle ratio, which is good for towing.  The ‘as tested’ price of this truck is: $51,560.

The temperature was around 41 F during the test, and the surrounding slopes had snow from the day before.  The roadway was dry and clear, the sky was blue, and the test was underway.

What Are We Towing?

We upped the ante for Ike Gauntlet 2.0 with a Logan Coach – Stockman trailer and large water tanks.  The water tanks allow us to fine tune the load precisely, and in the end we measured 10,010 lbs of trailer + cargo.  That’s not all.  Don’t forget that Roman, Nathan, and Mr Truck Kent Sundling are in the truck to provide the data and commentary.  Lets just say that the guys and gear add another 800 lbs.  All together – the load is 10,810 lbs.

The Way Up

The engine and transmission will be stressed to the max gaining more than 2,000 feet of elevation in just eight miles.  The maximum grade of this climb is 7%.  And the engines will be starving for oxygen and struggling to make power at the 11,158 ft finish line.  The test is to use maximum throttle input on the way up in order to maintain the 60 MPH speed limit (or the maximum speed the truck is able to maintain below that).  This is also a test for the driver as very slow moving semi trucks and other vehicles are obstacles to maintaining momentum and staying at 60 MPH.  (See the video for the time, summary data will be posted after all three videos are published).

Going Down

We want to know how capable the brakes and transmission are descending from the tunnel to Silverthorne.  This is perhaps even more important than being fast on the uphill.  The trucks must be safe and practical on the way down. The measurement is simple.  The trucks must maintain a safe and practical speed at or below the 60 MPH on the way down.  We measure the brake rotor temperatures at the bottom and the truck with the coolest brakes is the winner.  Of course, we also monitor the transmission and engine temperatures on all runs.  (See the video for the brake temperatures, summary data will be posted after all three videos are published).
