Death of the V8 & birth of a.... Inline 6?

The weak spot was the Venturi carburetor. At least on mine.

Oh God I remember those.

I also had a 1979 Ford Granada with the small inline 6. ~230cu/in maybe? It had a puny 1bbl carb on it that was always troublesome.

Weather dependent on how it ran and started ?

They can put a turbo on the Hemi and get better power also gas miles.
I get about 21 miles prgal out a 5.7 Hemi with 8sp auto and in city is a little less 18 miles prgal. Thats if I keep my foot out of it.

I always thought the old naturally aspirated in line sixes lasted because they didn't have enough power to hurt themselves. Lol

Hello all
I know this will be best to death. However you either get longevity (V8) or performance (I6). Ford, GM leArned thier lesson and now Ram will learn it also.

inline 6 turbo makes more power... gets better mileage... weighs less also... I dont see a problem... I mean the only issues is you can't go "its got a hemi in it!"... at the stoplight... thats about it, and thats an old commercial

they should have called it a Hemi though of some sort

Even if it isn't... marketing lies all the time..

I have a feeling the pentastar will continue to be the base engine for some time yet, with the hemi and the new hurricane being optional engines.

Given Stellantis is still building 4th gen Ram 1500s, I can't see the hemi or pentastar going away for some years yet.

My dealer advised me the Hemi will be around for several years.

This is what I Recently found on the net.

Dodge Challenger's 5.7-Liter V8 Hemi To Be Replaced By Inline Six?

The ubiquitous V8 Hemi is set to be retired with a new efficient inline-six taking its place.

Guess they could call them "Warm Kitty" instead of "Hell Cat"!

I really see EVs crashing hard. just from our power grid alone its going to be a disaster and raw materials for batteries is another. there isnt enough charge stations to ever think about switching to all electric, and if we charge at home good luck lol. 1.88 cars per house hold is a lot of charge stations lol California cant even run all the A/C units per house during peak summer months. Until battery technology gets a touch better i don't see this working for most Americans.

I guess you can run a little Generator in the bed if EV truck to charge it on long drives …lol

I loved the old slant 6. wish they could bring that back

Lmao people in Texas are doing that now. The whole state is having power issues already due to heat.

I'm a retired mechanical engineer with 32 years of powertrain design and application experience. I don't know everything, but turbos are ok for lightly loaded spark-ignited engines. Heavily loaded wears them out much faster than natural aspiration.

A NASCAR race engine, though naturally-aspirated, lasts app. 3 x 500 mile races (1,500 miles), because it is heavily loaded and runs @ high rpm. A top fuel drag engine with a blower lasts 36 seconds or app. 6 races.

The average consumer expects a car engine to last 200,000 miles, properly-maintained. By definition, spark-ignited engines are pressure-limited due to combustion initiation from a spark plug or two. So they can not be induction-boosted beyond a certain pressure without detonating (knock), blowing out the piston.

This is expected from a diesel, where the heat of the air is used to initiate combustion all over the fuel front. The extra pressure means they have to be built to contain it.

You don't get something for nothing in the real world.

I see you have a Hemi, but what do you think of ******'s 6.7L switching from iron to a compacted graphite iron block?

Not that huge a deal - it's an incremental heat treatment step on the way to forming nodular (also called ductile) cast iron commonly used in underground sewer pipes. The more nodularized the carbon in iron, the less brittle the cast iron is.

So CGI is halfway between standard flake graphite Grey Cast Iron and Nodular Cast Iron. A little more strength, a little more ductility, without all the cost of full nodular. It's like a half-a$$ed cast iron. lol

Which V6 are you referring to? Maybe it's a typo in your thread title. Everything I've read is saying the Hurricane inline 6 will be replacing the Hemi V8 in 1500's, not a V6.

There have been threads already, discussing this exact thing. Opinions have been very mixed as you can imagine. I'm of the opinion that substituting a smaller displacement forced induction engine to do the work of a larger displacement V8 is inadvisable. That a smaller engine will wear itself out faster than the V8 it's replacing. But that's my opinion. I hope I'm eventually proven wrong on that, because the Hurricane seems like a powerful, smooth running engine.

I'm old, took my driver's test in 1956 in a 1955 Hemi New Yorker. So, I'm prone to large engines. But as an engineer I believe engine technology has improved enough to allow durability. My big concern was the heat generated by twin turbos. I like the increased torque and HP. I tow an RV, and while my Hemi does a great job more torque and HP is always a good thing. Going to order a new Longhorn as soon as the I6 is available

Why? That thing was a mutt - which is why it lasted so long. My old man's was a gutless wheezer.

stormcom · May 16, 2022

It will last longer than an eco diesel.

Awokenotwoke · May 16, 2022

My opinion is Stellantis should have pursued an I5 instead of I6. One large advantage is the main bearing support on a 5 is greater than a 6 because they need the same number of mains. Get a beefy 3 litre I5 block and twin turbo’s at the higher psi and could have a virtually bulletproof 450HP engine. The I5 Configuration is the smoothest running, least vibration configuration design.

An i-6 makes so much sense these days. It will have plenty of torque to get the same jobs done. Maybe more torque than the Hemi. Plus be so much lighter. I'm sure we've all noticed that RAM is way behind on payload ratings compared to GM, Ford. That awesome V8 is crazy heavy. I don't expect MPGs to be that much better. Emissions will likely be better though. Which is a requirement to even sell a truck in today's World, not just the USA.

Electric will be big guys. Stop denying that. ICE powered trucks will not go away either, but will slowly become the expensive option. Both to buy and to own. I give it 10 to 20 years to become that norm.

2 problems...
1- I have worked on MANY turbos. All it takes is a grain of sand or two to get past the air filter and your fancy assed turno will eat itself. Seen it happen on a well maintained turbo V6. Turbos ain't cheap.

2- Until they come up with a truck that I can load my camping gear on and hook my boat up to it, then drive 4 hours to my favorite fishing hole, then drive back, I will never have any use for an EV.

All these Star Wars, Star Trek, Spaceballs looking EV's should never have been let off the drawing board.

Yep Ford has had that problem, Chrysler has not !!!! They make great turbo motors.

Yeah, nope.

Still no turbo.
