Hemi 6.4 - When is the End? (2024)

With Ram no longer offering 5.7s in their 2025 1500s, does anyone know when we will see the end to the 6.4s in Ram HDs?

I assume that we will see some 3.0 Turbo and/or Supercharged Hurricane as the replacement as this is what is apparently going into 2025 1500s as the Hemi replacement. That said, I can't see the market looking too fondly on a HD truck having exact same engine performance specs as the Light duty engine options so their will likely be something different to set HD gasser appart. Also, Ford offers their Godzilla engine in their HDs (presumably past 2025) so would seem counterintuitive for Ram to shrink their gas engine offering.

I've read in a few places that the 6.4 will continue in the HD line, but who knows, things change fast. Therefore, I grabbed a 2023 while I could, and am quite happy with it. That kill switch legislation for all vehicles in 2026 also helped me make my decision

The “kill switch” law that people are blabbering about all over social media is total crap at worst, and an exaggeration at best.

Main reason I put my order in for 2024 Power Wagon while I can still get a decent motor. I really hate a truck that can't get out of its on way.

I don’t think a gas 6 cyl turbo makes sense in an HD truck at this point, but a 500HP hurricane engine would move these trucks far quicker than the current Hemi does.

I agree. 500hp is a bunch, but lugging around a 7000 pound truck, while pulling my 10,000 pound camper, just seems a lot to ask of a 3.0

Fact check: No, there's no vehicle 'kill switch' in Biden's 2021 infrastructure bill

Automobile experts told USA TODAY that the 2021 infrastructure bill does not require a kill switch to be implemented in cars.

I sincerely hope so, if not, then I will be happy with my 2023 for awhile

What’s fraudulent about the EPA? I didn’t know they were deceiving anyone.

Also, most consumers don’t want a V8, they just want a vehicle that meets their needs. Doubly so for most customers of HD trucks, which are fleet buyers. Fleets would happily buy a 4 cylinder HD truck if it could handle the loads they need, was reliable, more efficient, and cost them less in maintenance.

Aren't 3/4 ton and up trucks not part of the EPA fleet mileage rules? I could be wrong about that, at least remember it being that way in the past.

Jsalbre I know what you mean about fleet buyers, but I do think that a good % of heavy duty pickup buyers want V8 power in gas powered trucks.

I guess "fraudulent" isn't the right word, or maybe it is depends on how you look at it. Their regulations are put upon consumers at a much higher rate than corporations that buy their way out of scrutiny. I wasn't intending to make this thread about politics and no desire to go down that path. I have my opinions on the EPA. The fact remains the same, we are looking at the increase of smaller displacement, turbocharged engines and EVs due to the EPAs push for it

In response to your 4 cylinder example, fleet may make up a good portion of consumers but they're in a class of their own in my opinion. When I refer to consumers I refer to those who walk into dealers and buy trucks for themselves. Im sure there's those who agree with you and you may be one of those who wouldn't mind a 4 cylinder that does all you need it to but Im willing to wager thats a very small % of HD truck buyers. Id also wager majority of fleet are in 1/2 ton trucks these days for exactly your point, cheaper to buy, maintain and replace AND most 1/2 tons are as capable as HD gas trucks 15+ years ago

You are correct. HD trucks are not counted towards fleet wide fuel efficiency standards. Which is also why you don't see city/highway fuel efficiency ratings on the window stickers.

But they are counted towards carbon emissions standards.

With them getting rid of the V8's in pretty much everything else it's not much of an issue to keep using them in the HD trucks. This is how Ford and GM continue to use V8's in their trucks and like 1 or 2 cars and not have to buy carbon credits to compensate.
