I think the real news is the Ford 7.3 gas performed almost as well in the up hill pull test compared to the Ram 3500 cummins and the Chevy 3500 Duramax pulling the same load. And the during the Ford pull they had to back off the throttle for a little bit so the time could have been less.
Here's the pull times in ascending order:
Duramax: 8:24
Cummins: 8:25
7.3L Godzilla: 8:42

So much for the "you gotta get a diesel!" crowd. Save 10k and get a 7.3L Ford gasser haha. The times would be even closer if it wasn't a test at 11,000 ft of elevation where the non-turbo gasser is losing hp.
Yeah, but if they set the max speed of the test to 70 mph or even 65 mph then those times for the diesels would be a lot less. However, since they limit it to 60 mph mow, you are not going to make a more perfect run than a little over 8 minutes.FishOnOne wrote:

According to my math the 7.3 was producing an average of 344 hp at the crank during that run..... and the throttle would have been backed off for part of the hill to keep from going over 60. Using the same math the 2020 Duramax put out 341 hp towing the 30k lbs up with the throttle pinned the whole time.

I know you are meaning for this to be your usual dig on anyhing other than Ford, but I bet the Powerstroke time would be the same since they limit the speed to 60 mph and 8 minutes is a perfect time of you do 60 mph the whole way. So given the time it takes to get up to speed and the occasional letting off the throttle that Mr Truck does occasionally, the Powestroke would likely be in the 8:20 range too.
Difference here is that the 7.3L is giving it all it's got for many portions of the Ike while all three diesels would be able to exceed 60 mph through most portions of the Ike.2001400ex wrote:
For the gas engines, Chevy has always been behind in the HD segment. If I wanted a gas engine to do work, Ford would be my choice.
I remember when GM came out with a gas engine for heavy duty that was so much better than Ford it was crazy.
With the flat power curve advertised not sure it will really use the 10 speed. On the down hill running 60 in forth. I'm assuming going up same speed/ same RPM. So on level ground at 60 MPH, the truck could be in any one of seven gears.- I think the real news is the Ford 7.3 gas performed almost as well in the up hill pull test compared to the Ram 3500 cummins and the Chevy 3500 Duramax pulling the same load.

Link - Ford put down a stomping with the 7.3, impressive performance. GM could have made a much better showing with one of 3 things and preferably them all. 1) Better transmission tuning, it should have downshifted on the IKE test. 2) 10 spd trans 3) 4.10 axle. I suspect we will see them all by '22 at the latest. I think from a marketing standpoint, GM figures if you are going to tow 16,000 lbs on a regular basis, buy a diesel. That was true before this 7.3 came along, maybe it still is.
On the other hand, Ford has a huge market already to put this new engine into with the various chassis cab and medium duty trucks. If GM ever wants to compete in that market, they better build the rumored 8.X engine.
The truck competition is fierce at the moment, they are all very nice trucks! danrclem wrote:
I'll somewhat agree with you but I'd think that it was a combination of both the 7.3 and the 10 speed. I have a 6.2 and I think a 10 speed would improve it but not to the extent of pulling the Ike in that amount of time.
If this engine gets 6.2 fuel mileage or more it should be a winner.
The 7.3 is beast, but I have to tell I don't know. Sure the 7.3 improves but if you had 4 more gears with 4.30s that would make a huge difference.
I went from a 2002 2500HD 6.0 4 speed 4.10's to a 3500HD 6.0 6 speed 4.10s. The 2002 was 300HP and 360Ft/lbs of torque the 2017 isn't really that much more at 360HP and 380Ft/lbs of torque. I will tell you those extra 2 gears make it so much better. It stays right where it needs to be for RPMs vs the old the old truck.
4.30s and a 10 speed is just smart. It keeps the torque/horsepower right were it needs to be a good portion of the time.- I'll somewhat agree with you but I'd think that it was a combination of both the 7.3 and the 10 speed.
