GM twins now J2807 compliant

GREAT !!!!

Finally getting off the 'curb'basis and using more real world (kinda sorta...who
weighs in at 150 lbs? and who has a trailer tongue of 10%)

Guess that 150 lb per person evens out a bit. I'm 180 and GF is 105, but
buddy is 312 and his wife 180

And options !!! guessing that 33% penetration has AC, automatic,
power doors, power seats, power windows and maybe a few more that
33% of the buyers order

• For light-duty full-size pickups (GVWR < 8,500 lbs.), SAE J2807 assumes
that the tow vehicle includes any options with higher than 33 percent
penetration;
• It assumes there is both a driver and passenger in the vehicle, each weighing
150 pounds;
• It assumes that tow vehicles also include up to 70 pounds of aftermarket
hitch equipment (where applicable); and
• For conventional trailer towing, SAE J2807 assumes that 10 percent of the
trailer weight is on the tongue

Keep in mind these only appear affect the 150/1500 range of Pickups.

One thing to remember Ford sets up this completion and choses the hill to climb.

Then ford picks the rear end gearing and you can bet they pick the best gear for the Ford and the worst gear for this hill in the GM and Ram.

Put a turbo on either the GM or Ram and it would be a no contest. Or let GM have 6.0 or 6.2 liter.

uh...ok. The ford had 3.73 gears (4.10's are available on F-150) and the Ram had 3.92 gears. The GM had 3.42 gears, which is the best you get on the 1500 trucks. But then again Ford probably requested GM not make 3.73's available that particular year so they could beat them so badly.

It was a good Ford commercial though. :S Kind of like the Chevy one where you see snow out the window. :B

For a large company like Ford, it was very easy for them to arrange for the entire strech of road up Davis dam to be air conditioned so the Ecoboost wouldn't overheat. :W

I think the point people keep forgetting is the 5.3 is the direct competitor to the 3.5 Ecoboost, such as the 6.2 GM is the competitor to the 6.2 Ford.

If you want to compare the 3.5 Ecoboost to the premium 6.2 engine of GM then thats fine...

You mean this 6.2 that barely beat the 3.5 ecoboost.

You mean "the most powerful truck in the land?" The one that handed Ford the loss? Yep, that would be the one! :B

Pretty much a far cry from OP's silly statement of: "GM doesn't make a V8 that can keep up with the EB" now isn't it? Not only do they make a truck that can keep up with it; it handed it a loss. Thanks for the link. :W

Now you're just being silly. What about the LS 6.2 at 420 ponies? :R

On second thought, maybe you were right. GM doesn't make a V8 that can keep up with the EB; with 420HP it will not keep up; it will be so far ahead that they will forget the EB was even in a competition. :B

You mean this 6.2 that barely beat the 3.5 ecoboost. The 420/460 numbers look good on paper.

GM 6.2 tow test

The majority of Americans don't live at high elevations. That compares a turbo engine vs a naturally aspirated engine at 11k feet above sea level. Not exactly a scenario that applies to 95% of truck buyers on a daily basis. Secondly for whatever reason the chevy wouldn't hold a downshift. If they would have manually selected 2nd and held it to the floor it probably would have done ok.

At lower elevations and manually selecting the gears the 6.2 chevy will eat the ecoboosts lunch. I think the highest elevation my truck has seen and is likely to see is probably about 3500 feet. I really couldn't care less what it can do at high elevation.


EDIT: Just watched the link and realized it wasn't the ike gauntlet tow test. Anyways it was still done at higher elevation and with the amount of torque management they put in modern trucks full throttle from a standing start isn't the best comparison of how much power is available for normal towing use. I rarely if ever leave a stoplight at full throttle towing or otherwise. If you want to talk which will hold the most speed up the majority if grades we will encounter towing I think the 6.2 has the edge.

Smart move if you ask me. Not that it makes any difference to me but GM can leverage their advertising to this now.

Going to be interesting to see how the ED comes out of this. With only 240HP it's going to have a hard row to hoe IMHO. Time will tell. :)

Going to be interesting to see how the EB comes out of this. With 365HP and a relatively small cooling system it going to have a hard row to hoe IMHO. Time will tell. :)

To me it will be nice to see them all play by the same rules.

The 'relatively small cooling system' and 365HP limitations didn't seem to be much of an achilles heal in this contest. Oh, and Davis Dam was the model for the cooling performance test of J2807.

I did notice the different in gearing. The usa is used to no truths in stories so maybe it is ok to lie about trucks. I call this test another un true story.

This was far from an apples to apples test.

The engine with the most horsepower most likely will win.

But I will admit the Eco Boost is impressive and I expect GM and Ram to follow.

As for Ford or Ram to be J2807 compliant! They do not even have their Hp and Torque claims certified. That is why GM has been king in all independent sponsored hill climbs. The GM Hp claim is real world.
