Hemi Engines

Almost all engines are hemi but other manufacturers can't use the word.

that is absolutely not fact. there are lots out there but not near

""almost all""

Hemi is just a name. It stands for Hemispherical combustion chamber and has a domed cylinder head. It has been in use since the very first engines and can be traced to 1901. Dodge did not invent it but were smart enough to copyright the term Hemi and hire a deep voiced actor to make it sound special. Almost all engines are hemi but other manufacturers can't use the word.

Hemispherical cylinder heads (ie: Hemi) have been around forever and are still used by many car manufacturers today. Chrysler trade marketed the term "Hemi" in the 60's so no one else uses the term, but the head design is the same. The design allows for a better valve angle with larger valves so more power for a given size. However, the cost and weight is greater so like with everything in life, there is a compromise.

Not true! First off the 360 was 5.9 litres. The 5.7L " Hemi" was a completely new design dating back to the 2004/2005 time frame. They are not even close to each other....

You guys looking to put your RVs on the drag strip? :B J/K with ya!

Not sure WHY Dodge has never gotten into the RV game, and why GM got out of it. But, everything I've ever read about the Triton V10 is positive...well, except for those few years that they didn't put enough threads in the spark plug holes....

Just remember, though...horsepower gets you to the end of the track faster, but torque is what makes it FEEL good getting there!

The Workhorse Group has not mentioned the RV market again apparently since that May, '15 release. They seem instead to be concentrating their resources on their E-Gen hybrid truck chassis and the HorseFly Drone program.

Workhorse Group Media

The Workhorse press release was 16 months ago with not a word since - and nothing at all on their web site about it either.

Makes me wonder if they had a change of plans.

It's not that they're without an available engine with an 8.8 liter and if they do ever start up again, as stated here....
WH coming back
When Navistar International bought them out, they thought they had a winner with their own little in house front mounted Diesel, but we all know how long that lasted, with most all manufactures going with a Ford chassis.

Tropical36, since Workhorse is back in the RV Chassis business when is there first unit due out? Do you know what brand of engines there going to use in these units? Thanks

The monopoly that Ford has on the class A chassis market blows my mind. There was talk a couple years ago of Chevy getting back in with some very impressive gas motors but it fizzled out.

The Hemi engines would seem to be a great fit. I do see them trickling into some tow trucks and flatbed trucks so who knows. But for the foreseeable future it's Ford V10 only. The Ford V10 is a great engine but the HP and torque ratings being produced are pretty "ho-hum". I don't understand why my 7000# Hemi gets 410HP and the Ford V10 to haul a huge class A only churns out 330HP. I think the Ford may put out a couple more lb/ft of torque than my Hemi which is 430.

It seems the market is ripe for a 450+HP/500+ torque gas engine in a class A chassis. The engine technology is there and there are a lot of RVs selling these days. I've been casually looking at class A coaches for a couple years but am pretty happy with my 5th wheel. A better gas power plant would sure be nice. I can't justify/afford a diesel pusher yet with my weekend and summer use.

I agree!

Wrong there still a hemi designed head,valve and pistion arrangement so their a genuine hemi engine 5.7 6.1 and the 6.4
