Ike Gauntlet 2.0 (6.2 Silverado, Titan, F150 Ecoboost)

I really don't worry much about torque curves, I just want the power when I want it and yes the GM 6.2 makes it at over 3500 RPM..Works for me.

This statement is a little contradictory. I brought up the curve because that is the only measure of total output from an engine. Acceleration follows the torque curve and I was just pointing out that this test wouldn't be "extremely different" at lower altitudes. If the Chevy had a quick shifting 8 - speed to keep it revved up, then one might be able to throw around the word "extremely". With the wider gears I think the Chevy will still win but not by an extreme difference.

What I meant to say is that I don't pull of the curve specs and study them. I'm more of a seat of the pants type. I know it when I drive it as to whether I'm buying or not...I don't get that carried away with statistics for better or worse.

I guess the engineer in me likes numbers and graphs. My butt dyno hasn't been calibrated lately. LOL

The standard formula I have seen for a normally aspirated engine at a given altitude is hp loss = elevation(in feet) x 0.03 x hp (@ sea level) / 1000. For a 400hp engine at 10k feet that would be about 280hp, 30% loss of engine power. At 12k that would be 260hp, over 35% loss in hp. That 6.2L engine is acting like a 4.0L 270hp engine at 12k feet. To me that's pretty extreme.

Why then did the Chevy have slower 0-60 when TFLtruck tested it in Texas? Something isn't adding up.

All true, except I don't have to pull in 10,000-12,000 feet and most of us don't---Ego the stupidity of the test...So I buy what works for me in the altitude I live in. If I had to do 12k, I'd add a blower or a turbo or something...Given that I don't, I won't.

Hands down nothing in this segment can compete with the Eco Boost. That's the beauty of this package in the F150. It can do everything well, not at just some weights or altitudes and all the time give you a comfortable ride, great power, and good mpg.

I wonder how the new Ram 1500 diesel will compare with the Eco Boost...

I don't know how those guys got a job testing vehicles, they don't seem to bright.

Kind of like their "solution" for not overloading the truck was to decrease tongue weight less than 10%?

I watched about 3 minutes of the video and realized these were a group of idiots then stopped watching. Reminded me of a group of high school kids that had borrowed their dad's trucks for the night and got into a pissing match. Maybe I judged too soon but I didn't see any credible info coming so I turned it off.

From what I remember, the ram diesel is rated at the same torque but quite a bit less HP. This tells me that the torque curve is very short. In addition, the ram 1500 has very low payload making it have a low tow rating. I think it is going to be a great combo for fuel efficiency and light towing.
