Thumbs down.
Seems maybe Pickuptruck.com cheer for the blue oval.
All trucks and trailers were completely on the grade and stationary before each run. All the tests were performed โbrake-to-accelerator,โ meaning the foot brake was fully depressed with the right foot, which then lifted and fully depressed the accelerator pedal in one movement.

I'll bet if they lined the "Egoboost" next to the chevy and instead of the ford embarrassing the chevy to the top of the hill it just stayed with it the mpg would be very similar. You are correct that the turbo 6 was working hard, it climbed the 7.2% hill to 40 mph almost 2.5 seconds faster than chevy's brand new powerhouse!! Thats what I think is impressive. :B
12.6 towing 8500 pounds is impressive I think. That egoboost can not match the smallblock chevy even thought it has all that extra power that tells me the turbo 6 is working hard.

It is the result of the gearing of the trucks. Lower gears equals better acceleration and of course fewer MPG in most driving situations. Really a stupid test as who really cares whether a truck takes 7.1, 7.2, or 7.4 seconds to accelerate onto a freeway.
The Toyota is going to provide the fewest problems and cost the least for maintenance and repairs and it has gotten the JD Powers award as the best truck for the last 5 years in a row.

We've been very satisfied with our Tundra but it's not surprising the Tundra finished down the list. It's a 7 year old platform and has grown long in the tooth. The big 3 trucks are basically a generation ahead of the 5.7 Tundra. Interested to see what 2014 will bring.

I don't think it would have made much difference. The turbos on the Ecoboost are small and really only made to service an under 2.0 Liter engine. They are designed to spool fast and are heavily managed by the ECU.
In the car application of the 3.5 Ecoboost it has been found to not really matter if you brake-torque it or not.
Edmunds SHO Comparison
"The SHO didn't respond (good or bad) to brake-torque, so best launch was at 2,000 rpm."
My guess is the stall speed of the Ecoboost Torque converters is set so that it is close to when boost is starting and that's why brake torquing has no effect.
Bottom line is the EB has the advantages of Diesel (flat torque and lots of it) with few of the drawbacks (service cost, expense, weight).

Here's the summary for the truck challenge.
BTW... The GMC is starting to grow on me and there's no doubt the Ford and RAM are starting to look long in the tooth and the Titan is already in the pasture.
