New Super Duty and Chevy HD Gas Engines ?

[Ejs4029]

Was doing some reading on the new gas engines that are slated for the 2020 Ford Super Duty and Chevy HD trucks…..The Ford 7.3 with the 10 speed auto and the Chevy 6.6 with 6 speed auto ….Are these new offerings going to be a notable step up comparing them to the Ford 6.2 and the Chevy 6.0 that are currently offered ?

The 7.3 gas is going to be a beast. Not sure on the 6.6 gas.

I caught this today also. I would think so in both cases. The 6.0 has been great but was due for a refresh. The 6.2 is also great and is still the base with it's big brother now planted between it and the 6.7. I like that fact that Ford offers the choice of the 6.2 with the 6 or 10 speed and the 7.3 only with the 10. I'm interested to hear why GM kept the 6 speed with the new gas motor. Either way, I'm excited to see what the numbers compare to against each other and what the ike tests find out. I'm slightly concerned with GM's 52% increase in tow rating(TFL stated that) but hey it's about time. Pricing...well that will be something else.

I can't comment on GM, but will offer thoughts on the Ford 7.3:

The 7.3 specs haven't been officially published, but all signs point to a massive increase in torque and HP. Should be a very attractive option for those needing more grunt but don't want to go with a diesel (for various reasons). Pricing hasn't been announced, either, but I suspect that it will be $1 - $2K. Years ago, Ford had a V10 option and it was around $600.

The 7.3 should nicely fill a gap in the HD truck platform.

I'm much more bearish on the 10 speed transmission. The current 6R140 transmission is one of the best that Ford has ever built. In fact, it's one of the all-time best HD transmissions, with many outlets rating it higher than GM's Allison 1000.

My guess is the 10 speed will be merely OK for a year or three. Just a guess and based on nothing but skepticism. I'd have a hard time signing up for the first year of the 10-speed.

and extremely durable.... remember the 2011 Ecoboost performance tales?
1st year production..
nope I will keep my 2018 Super duty thank you very much

The GM 6.6 gasser for 2020 looks promising, but some aspects I am skeptical of. According to GMauthority website, it will incorporate direct injection (expected) and the AFM cylinder deactivation nonsense. The latter I am skeptical of in a serious working engine.

But the 6.0 really isn’t bad even though some think it’s a dinosaur. My rural hilly gravel roads turned to soup this last weekend. Needed to take my 21,000 lb semi tractor to town, but it buried itself in the soft muddy road. Got the wife to bring the Silverado 2500 6.0 out and we hooked it to the semi with a HD tow strap and she drove the 2500 and pulled me 2 miles thru the muck, over 7 short but steep grade hills to the hard top road.

Someone will have a tough sell trying to tell me that the 6.0 just can’t pack the gear.

I like that they left room for a future Supercharger or Turbochargers if need be.

[nayther]

I'm very interested in this as I'd like to go gas on my next/last company truck that I'll take with me when I retire.

[MT Biker]

My guess is the Ford 7.3 will be a big dollar upgrade, somewhere in the range of $3000.
Also wonder how much it will effect the payload numbers on the F250, will it be as drastic as when you have a diesel?

[67L48]

$3K is a good guess that I wouldn't argue with. I didn't corroborate the old ~$600 upgrade price of the V10, back when it existed. If I were running the show, I might even go higher. If the diesel is ~$9K, then the big V8 should be in the $2 - $5K range, somewhere. No free lunch here. If you value it, you pay for it!

As for weight, if possible, maybe look to see what the effects were back when the V10 was an option. They're old data that may not be readily available, but if you could find a few examples of payload, it would probably be directional to what the 7.3 effects would be.

I would be more interested if Ford would use some of their Ecoboost technology in a V8.

It already does. It’s called the Raptor.

[Mad Cow]

I side with the supercharger approach when it comes to V engines. Two twin scroll or VGT turbos which require water cooling adds more complexity, potential problems, and increased overall costs to something that can be accomplished much easier. Simplicity is always a good thing with consumer engines. Save the wild stuff for the race track.

I don't think id be to skeptical with the cylinder deactivation. It works great on both my 6.4 Hemis and the mileage I get with the 485hp Charger last trip 27mpg Most manufactures using the technology now anyway. Later RJD

It's not a V-8, it still the same 3.5 V-6 just tuned hotter!

Just an old Army Cavalry Sergeant, I pay for 8 cylinders, all of them have to pack the gear all the time. No gooberment, union, or OEM sponsored rest breaks for any cylinders while the others work.

As Scotty on Star Trek stated so well... “the more complicated the plumbing, the easier it is to stop up the drain”.

Glad I got my 2015 2500. I won’t need anything else for a long, long time.

Give it a couple of years to make sure they have the bugs worked out of it. They are switching from the V-10 in the Class C, E-450 to the new V-8.

[Blackrock]

There is no replacement for displacement. Something we've known all along. I had a lady friend with a class C and a V10 Ford. I really liked driving that thing.
So now if Ford and GM can get back to building large displacement engines with the new fuel management technology I think things will be changing in the towing game.

Im gonna wait to see where they're going to be manufactured. I only buy from a company owned by an American company and one that manufactures in country.
