Great application of the turbo I6 but sluggish throttle response is annoying.

Zero development for 15 years on: Durango, Challenger, Charger, 300 chassis and bot 5.7 & 6.4 NA Hemis. Everything was live for the moment supercharged Hemis and sending money to Italy. Only new trim packages for the US and spreading technology from top end models across other productlines...

Some if us are engineers and have been MOPAR fans for 40+ years but the people running CDJR are following the crowd without even trying to be innovative. Mercedes helped develop and release the Hemi, then 5 years later, an upgraded 5.7 with even better heads, cam phaser, and active intake. No...

What people like you aren't getting is, we understand regulations and see a total lack of effort that CDJR has put into a pushrod V8. Nothing since 2009 while GM has released many iterations of theirs. OHV engines can have compound valve angles and a wedge chamber that an OHC cannot match...

Too many ignorant, simple minds like yours on this site. CDJR has put Zero, again 0 effort into a new Hemi (Semi Hemi) V8 design since 2009...that is the problem. Incompetence at the top, Period. If you follow racing, you'd see some amazing development in OHV engines that have compound valve...

Why don't you go home where it's safe and leave the discussion to the adults with some knowledge. You're comparing a 2009 5.7 OHV Hemi with a 2009 5.0 DOHC. They're both out of date and a OHV motor will get better fuel economy than the DOHC engine because N.A. engines like a wedge shape...

It's not a bold move, rather your only move to drop the Hemi when you're incompetent. The valve angles should have been straightened up from 16° intake to 10-12°, then rotated 15° to fit an injector into a chamber closer to a wedge than Hemi. The a single plug down from the tip. It would be...

FCA should have branded all of the ALFAs under the Chrysler name and not had separate delearships. Money should have been put into two new Hemis one being a baby Hemi to use the smaller 8 speed. No vision and no drive in upper management.

There definitely is a way but not when you wait 15 years and try to catch up. All upper management at FCA was on a short sighted plan and no vision. It's caught up with them and they blame the EPA.

No development since 2009 is the reason. The valve arrangement could be twisted, canted, quenched, and DI added. A DOHC chamber is not far from the Hemi design which Chevy, Mercedes and Ford are promoting their V8s. MotorMaven, Why are you such an apologist for lazy, short sited management...

You didn't keep the V8 around, you're struggling with EVs, maybe you should get into another line of work...take all of upper management with you.

Must haves: 1. 5.2 Hemi DI V8, 120 lbs lighter than 5.7 Deck 8.65, Bore Sp 4.1, 3.86x3.40 w 5.75 rods, Mains 2.25", Rods 1.88", 12:1 comp 2. Vehicle weight 4,ooo lbs max 3. MPG 18/28 or at least 17/27. 4. Daytona should've had an aluminum block 426 Hemi, 4.18 bore 3.88 stroke. Tim...

Same architecture and engines (3.6 & 5.7) from the 2011 launch. Stellantis (CDJR) & the UAW are a Joke. I hope they file for Bankruptcy.

To bad FCA didn't put that $1.675 Billion into engine development. All the gas guzzler tax paid by owners of the Hellcats into developing better fuel economy. A bunch of slackers.

No technology improvements since 2009 on the Normally Aspirated Hemis...is anyone really surprised? Upper management is a major disappointment, so many wasted years Tim Kuniskis is a short sighted opportunist...Way to run the Hemi into extinction Tim! Ford, GM, & Mercedes have big plans for...
