• Ike Gauntlet Mashup: 2012 Ford F-250 v. 2014 SVT Raptor – Focus on 6.2L


    ford f-250 ike gauntlet extreme towing test ike gauntlet video raptor

    Ford introduced the next generation 2015 F-150 at the 2014 Detroit Auto Show.  There are lots of interesting bits of news, but there is also the fact that the 6.2L V8 will no longer be offered in the light duty F-150.  There is no word yet on the next generation SVT Raptor either.  If you are saddened by the news of departing 6.2L, you can watch this Part 1 of TFLtruck Ike Gauntlet 6.2L mashup.  It’s the 2012 Ford F-250 versus the 2014 Ford F-150 SVT Raptor.  Both are Super Crew 4×4 trucks and feature the big V8.

    First up is Mr. Truck’s 2012 F-250.  This truck has no modifications to its engine or drivetrain, but it does have after market rear air suspension from AutoFlex.  The Super Duty 6.2L V8 is slightly detuned for longevity and reliability.  It’s still no slouch with 385 hp @5,500 rpm and 405 lb-ft @4,500.

    This extreme test is designed to showcase how the trucks cope with towing a heavy load at high elevation and up a steep grade.  This Ike Gauntlet mashup is going down and up the eight mile stretch of interstate I-70 between the Eisenhower/Johnson Memorial Tunnel and the town of Silverthorn.  There is more than 2,000 feet of elevation change with an average 7% grade.  The finish line is at the top is 11,158 feet above sea level!

    The load is the Logan Coach trailer weighing in a hair above 8,000 lbs.  This weight was chosen because it’s the maximum trailer rating for the SVT Raptor Super Crew.  There are also three of our favorite reporters inside the truck: Roman, Nathan, and Kent (Mr. Truck).  This brings the total load to around 8,750 lbs.   In the end, the load is well within the 12,500 towing rating of the F-250 SD.

    How did it do?  Will this F-250 simply stroll up the Ike Gauntlet?  Watch the video at the bottom and take a look at this data table.

    Power Loss

    We are starting to measure calculated power loss on this and all future Ike Gauntlet runs.  We need three variables to get this accomplished: barometric pressure, ambient temperature, and relative humidity.  We measure this with a portable weather station near the Eisenhower Tunnel (at the top of this test).  This time the data was: 19.76 inHg of pressure, 33F temperature, and low relative humidity at around 20%.  The result is a calculated 33.1% loss of power at the top of the test relative to the standard provided by the SAE (Society of Automotive Engineers).

        1. I have been. Some have checked it out and others are terrified due to their brand not finishing where they want it to. Brand loyalty in the pickup market is very strong but these tests simply take all the manufacturer bs and put it to a tough and fair test.

    1. would like to see the f250 6.2 pull the 10000 lbs like the chevy and ecoboost did too..it was a good video though

    2. I’m a little surprised at this test. Looks like the F250 6.2L could use a deeper rear end than the 3.73’s. The trailer is only 70% total weight that the truck is rated for and it ran in 2nd gear near redline for most of the pull just to hold near 60 mph? A rear with 4.10’s or 4.30’s looks like it be better for towing especially in mountainous terrain and could hold 3rd which would put it closer to its peak torque. It was good to see the tow/haul mode hold one gear instead of constantly jumping. A F150 with max tow and max payload packages wtih ecoboost might be a better way to go.

    3. Interesting test. Seeing the V8 run at 5000 RPM makes me cringe! Maybe it is just that I am used to Cummins Diesels, but 5000 RPM is hard on the engine. I wonder how the cooling system will handle that type of pull on a hot summer day? Maybe a repeat test with 4.30:1 gears is in order? I would like to see similar tests with the new 6.4 V8 Hemi in a RAM with both the 3.73 and the optional 4.10 gears as well. I think many people who have had diesels in the past are glad to have some gas V8 options again. Keep up the great work.

    4. If my math is correct, the difference in axle ratios is actually equalized by the difference in tire heights. The F250 is running a 265/75/16 (or 17″ equivalent) which calculates to a height of 31.64″ while the Raptor is running a 315/70/17 tire which is 34.36″ tall. If we take the taller tire, divide it by the shorter tire and multiply it by the shorter tires gear ratio we get it’s effective ratio. 34.36 / 31.64 = 1.08 x 3.73 = 4.05:1 4.05 is awfully close (1.3%) to 4.10 so the effective gearing is nearly identical. I.E. – if we were to install the taller tires on the F250, we would need to install 4:10 gears the differentials to make the speedometer read correctly.
