3.0L Hurricane Updates?

CVT's are where it's at. Ok ok, hear me out!

Infinite gears, when programmed correctly they can always give you the lowest RPM required for the job. No busy downshifting or upshifting or engine wailing unnecessarily. Towing up a hill? The engine revs just begin to climb to where they're needed, and then back off again at the top. No change in speed, no jerking gear shifts, no busy feeling. Just raw power applied as needed.

And of course you can have a fuel economy mode where the engine revs as low as possible, or a sport mode where the engine is 300 to 500+ rpms above where its needed just to give you that effortless punch.

My parents have a CVT and it's not a sports car by any means, but in a truck... if it could hold the required torque (which might be a problem), I think the "mushy automatic feeling" issue might not be as much of a problem vs guys in camaro's and mustangs who would die if it came with a cvt.

Meh - let's go all the way to hydrostatic.

Recirculate the waste heat into a gas turbine recuperator.

A former boss worked on one of these science fairs for Chrysler in the 70s.
Then the Jetsons spacemobile would be soon thereafter.

Hydrostatic drives might be an idea though,it's been used in farm tractors since the early 70's

I was sarcastic. I have one in a Deere tractor. We used em in high load missile launchers and guns in the Navy as well.

They're only like 60% efficient, the heat rejection is enormous.

That's the downside to hydraulics,the heat generated,but if there was a way to recoup it,you could up the efficiency level.That's the million dollar question,what to do with the recovered heat in an automotive application

Gears are still the top efficiency power transfer mechanism @ ~ 95% efficiency for straight spur gears with a good AGMA class fit and syn lubes.

CVT likely not as efficient due to funky geometry adding friction, and they'd have to be enormous to handle heavy duty torque loads.

I guess there's no free lunch in physics. 10 speeds is getting kinda wild for an automatic in terms of cost and reliability.

CV transmissions have been around a long time to,nothing but a glorified snowmobile drive,lol. I tend to agree they'd have to have a hell'va belt drive to handle the loads and heat generated in a heavy duty application to offset the friction loses

I still miss having a manual.

The later Viper V10's are even bigger at 511.5 cubes,lol

Torque Monster: A Closer Look Inside the SRT Viper V10 - EngineLabs

Sure to draw a few snide protests, but the SRT Viper V10 boasts the highest torque of any production naturally aspirated engine. Here's a closer look at the all-alloy, OHV engine that features variable valve timing,

I hear you, but it's not a HEMI!

Hemi's are only for @Wild one

The rest of us need a DOHC modern engine for towing. Hemi's are for racing.
