Ike Gauntlet 2.0 (Eisenhower Tunnel, Colorado)
The 8,000 lbs load from the original test was not slowing these trucks down enough, so Ike Gauntlet 2.0 raised the ante to 10,800 lbs. MPG is measured only on the way up as provided by the factory computer.
Year Make Model Up (sec) Up (MPG) Load (lbs)
2013 Ford F-150 Crew 4×4 EcoBoost 7:36 2.9 10,800
2014 Chevrolet Silverado Crew 4×4 6.2L 8:26 3.4 10,800
2014 Nissan Titan KingCab PRO-4X 9:08 2.8 10,800
I am not even sure how relevant I70 is to most owners, but it is to me living at 6200 feet. However, the numbers are not apples-to-apples. This is basically a new test and grading that they are using. They made it clear that they have no other numbers to compare as of now. The previous tests (Ford and Chebby) used closed trailers that are likely more of an aerodynamic problem than the flat gooseneck trailer. Both of those other trucks also started from a dead stop, where it appears the Nissan was rolling from the start.
As much as I like what TFL does, they are changing the game more than game changers at this point. . .
