It's really a lot of screwing around for what? You can have all of this or an atkinson cycle NA engine with a hybrid CVT and get better fuel mileage, much better reliability, and better driveability also. '
That engine makes about 200hp. Virtually the same as an NA 2.5 gas engine without special tricks.

Screwing around? Variable duration has been goal for every mfr. for a long time, lololol...
Atkinson/hybrid CVT,....yeah, THAT'S less expensive & less 'screwing around', again....lolol..
Or........one could apply it to the 2.5 & have 312hp instead.....oh wait,...they did..
EDIT: I am actually a fan of CVT's, while most are not, but I see no reliable & workable RWD options on the horizon.

Whole vehicle probably sold for less than that.
I'd just be happy to retard/advance the cam in My old stuff, this is more effective & precise than V-TEC..
Hy has issues with cam CVVT oil control leakage, uses an electronic actuator with slip rings on the Intake cam...many other issues, but the CVVD system is ingeneous and not that complicated. The control software is the intricate dance to program precisely.
450hp and 25 mpg....and passes emissions
and can cruise at 130mph all day ,with ac on and cooled messaging seats

Big blocks rule small blocks drool!
I just saw something about that exact engine, the reviewers were saying it’s a dog.

Look at that mess, looks like AI drew that. lol
thats out of a 2013 audi s8
twin turbo in the middle ,intakes on the out side
needed intake manifolds
same engine in my 15 a8

my 13 was chipped never felt like it needed more power ,hit the thottle and 90mph and it would pin you back i little ...i est 560hp
thinking of tuning my new one

In each case when they do it you get virtually the same output as a slightly larger NA engine. And the same fuel mileage without a hybrid or anything else. In this case it's also a Hyundai so that's a strike against it already. I don't think these are as bad as the 2.4's of theirs but still...
I had a small displacement turbo car, you hate it on an 85 degree humid day.
The "eCVT" hybrid transverse transmissions are the best thing out there. 2 motors and a few gears, nothing to break or wear out. Not like a conventional CVT or an 8/9/10AT
Hybrids have no starter or alternator at all. Or belt drive. The transmission and motor inline with the crank do it all. Atkinson is basically camshafts.
Owning a Toyota Camry hybrid I can really say it's the way forward. Drive a large car, 45 mpg in the summer even with short trips, 0-60 under 7 seconds, never in the wrong gear, instant and smooth power delivery. Mine even has AWD.
Toyota is the only one that did hybrid right
If it a plug in you need to force the engine to run ever once in a while...and change the oil every months if they don't run they sludge up
One of my customers has a 24 vw passat
He gets 35mpg with nothing crazy
1.8 turbo 6spd auto
Has diesel only got 45

Lol, You're trying to make this a N/A Hybrid vs Turbo ICE arguement, it's not. If You'd have read My posts in any of the EV/HEV threads You'd know I'm pro-HEV platform, even tho' they're still waiting for much improved batteries....Ag/solid-states are on the horizon....
But CVVD is applicable on any ICE application, & hardly any more "screwing around" than adding all of the accociated hardware & tech for HEV's.
Feel free to post any links to other tech We won't be able to use in/on Our classic Mopars. I was interested in the inertial storage/kinetic flywheel system, but to be useful in a small package like F1 = $$$$
Yea im ok with ev cars
My wife could drive one with her commute
But she would forget to plug it in
Funny cause a lot of techs say its the end of the independent shops
No it you just need to tool up for them
Its just no way can are grid support them
And batteries need a break threw
And I don't see many lasting 20 years and someone spending 20k on it for a battery replacement

Just another dumbass
You won't see anyone in 10 years saying what a great barn find with any of this new stuff. If they do it will get a LS swap just like everything else. No support for any of this in stuff in the future. They just want to sell it and move on. When it breaks they will be more then happy to sell you the latest creation and throw that big *** batter in the trash. The dealership I retired from still has lots of electric challengers they would love to get rid of.

I don't know that you can't use it, more just how badly do you want to put it in there or does someone make it aftermarket.
The Freevalve setup seems like it could do the same stuff the CVVD system can do, just "easier" in a certain sense. Being able to program literally any cam profile you want into it is a blessing and a curse though. On the one hand you have near infinite possibilities on how you want to tune it, on the other you have infinite possibilities on how to tune it, so it can be really hard to actually decide how to tune it. Essentially it's a problem of "controlling more variables lets you be more efficient", but the more variables you have to control, the more you have to understand the interactions between all of them. You start piling tables on top of tables for tuning parameters and it gets really complex and multi-dimensional. Still really cool from and engineering perspective though.
I've kind of debated throwing an e-torque system on my car for the fun of it if I could find a way to control it. I already have a 5.7 Hemi swap in my car and the e-torque is basically just a 48V alternator/motor as far as I understand it. If I could get a third party control system it would be fun to have a "push to pass" kind of button for the setup.

Tech for Tech's sake is idiotic, and being that I am actually in the automotive industry as an engineer for 17 years as an engineer and a further 4 as a co-op, I see this a lot. I think this is a poor system because the NA versions make the same power and fuel mileage as anyone else's and the turbos aren't that impressive either. As was mentioned its worth 4% fuel economy and 4% power other than without it. So 8hp and 1 mpg.
It's cost with little to no benefit. Anytime you add something like this there's a multitude of additional chances for failure, so it better make a real benefit, because as we know, almost nobody that buys it actually cares if it's there or not, so are they willing to pay extra for it? Probably not. Compared to just making straight camshafts or a switch duration system like VTEC this is probably $100-200 per car without making much of a stretch. $100M in profit you didn't get if you sold a million. I just don't know why they'd feel the need to approve this for production.
That and when you're into today's world with extremely precise fueling and timing demands, when things wear (and they do because people think 10k mile oil changes are ok), what's really the tolerance for wear before you get a light and then, in many states, you cannot pass emissions without fixing it. It probably should have stayed a pet project, I can hardly believe someone funded that for 9 years!
HEV on the other hand adds a real benefit in fuel economy and emissions, and when you have things like CAFE and emissions it's worth it. In a way it's a simplification of mechanical components due to the transmission and the removal of the alternator, starter, and belt drive. In real good systems it virtually doubles the city fuel economy. Nevermind the car drives better.
I would say freevalve is a nightmare for passing durability which is why you don't and will not see it. Even if someone was going to pay the cost. It's always cost.
I don't think the eTorque is worth a whole lot honestly. it's the worst type of hybrid system. It seems that system is geared more towards stop-start with a small amount of assist.
Yea think its a better start stop because you can roll with out the engine starting
I heard they finally dumped start stop
I tell everyone to turn it off
Nothing worse then taking off from a stop light before your car builds oil pressure
And not good for batteries always loading them before you can fully charge them

And 4 long paragraphs later still arguing with Yourself about something You're not impressed with,.....lol...
Oh, if Hy can't build a reliable CVVT, I'm sure there will be issues....see, I worked there for 11yrs.......& My buddy José just left for a Lexus Dealer. But if there were a system I could put in that gave Me a 270°-300° range of tunable duration, I'd have it. ****, can't hardly stick FT Cam in w/o it turning into a FL Cam these days.....so much for reliable...

Not arguing with myself. Statement that it's of no value.

Forgot I needed to tone down the detail for the audience.
Yeah, but just look at that pile of...whatever it is.
Pointless detail because the prospective app is old iron,.....not modern 4/5-valve 13:1 CVVT Direct/Dual FI, Coolant zone-valved active intake/tumble enhancer engines......hope You built extra parking space in Your garage for Your arrogance.....lololol...
