Still very interested in hearing what y'all think about what effect max HP at a higher rpm in the new 6.2L than before will mean in performance (and even economy), especially when towing. Any thoughts?

 

What it ultimately means is they brought the torque curve up earlier, sacrificing some torque at the higher end.

HP = (torque * 5252)/RPM

That means it's making LESS torque up high, but at a difference of only 250 RPM, that's basically a statistical anomaly

What I see from these numbers is, everything being equal (like gearing and tranny), it'll pull better at lower RPMs without sacrificing any (or a small fraction of) top-end power.

If they're changing the tranny and adding more gears to it, I can only see that as even more of an advantage.

The lower peak torque number will also help it pull in overdrive at highway speeds. It might get better gas mileage on the flats pulling big loads.

Until someone gets one under their rear-end and pulls a load, all bets are off ...

 

Until we see a torque curve it's going to be hard to see what the difference would be. I've been running gas motors for so long that going from 4500 to 3800 wouldn't be that big a selling point and 25 more ft lbs of torque won't make me run out and buy a new one.

I remember when I was looking at buying a 6.2 the curve that 5 Star put out was pretty flat from 3200 to 4500 and when I'm pulling that's where it pulls the best but after 4500 it really drops off. The HP and Torque curves intersect at about 4500, HP climbs and Torque drops off fast. It will be interesting to see a HP and Torque curve at the rear wheels.

I would add that if I was a first time buyer the increased torque at lower rpm would be a plus when making the decision to go to the 6.2.

Remember the max power is only needed for short periods of time when pulling the rest of the time you are using a small amount of available power.

 

I agree that the increase in torque at a lower rpm is good for towing (and fun!), but increasing the rpm for max HP seems to be counter to towing performance on the highway.

I too think it will be good to see the power curves on the 17. It could be that the new curves are flatter and my fears are for naught.

 

Again, it's only 250 RPM... that ain't much. If it was 1000, I'd be worried.

 

You're probably right. I wouldn't think that Ford would do anything to negatively impact towing performance and economy for 2017 SD trucks with the 6.2L engine.

As you said, "Until someone gets one under their rear-end and pulls a load, all bets are off ...".

 

My long time friend at my Ford dealer just got back from their dealer event in Washington. He said out of all the new SD stuff they saw/drove/towed, the new 6.2 F250 was the biggest improvement in his opinion. It was night and day better for performance. This Gen2 6.2 is going to be sweet.

 

I can't see myself running at 5500 or 5750 rpms sustained up any grade, so I think the difference will be un-noticeable.

 

Night and day heh? I'll be sure to test drive one when they hit the lots around here. And see for myself.
