The problem with the FCA Pentastar engine is the name... Pentastar... Penta... which means FIVE... not SIX. On top of that, the cylinders are not arranged in a star pattern, but a vee pattern:

.

Thus, the engine associated with that name is all wrong. A suitable engine with the Pentastar name would be this:

Thus what FCA MUST do is redesign the Pentastar so it is a 5 cyl radial engine.

OR rename it to ‘Hexa-V-a-reeno’

New rule: every manufacturer needs an engine that looks like their logo.

Considering the quality of FCA products, I would never trust any radial engine they produced.

Even then, “Pentastar” is a terrible name because it does nothing to distinguish itself apart from any other Chrysler engine . Any Chrysler engine could theoretically qualify for that title . It would be like Chevy introducing a new line of engines called “Bowtie”, while continuing to also use Chevy-branded non-“Bowtie” engines.

It’s also kind of a one-time use thing. Now that Ferrari has a car that is essentially named “THE Ferrari”, all other Ferraris are allegedly less of a Ferrari than this “now and forevermore definitive Ferrari”. It’s stupid. They could continue to use that name on a second generation of that car, and improve its performance, but the name implies that they will never make anything better than a LaFerrari.

“EcoBoost” is an awful name too, but at least it does something to imply forced induction. It’s marginally better than naming a line of engines “Blue Oval”.

I prefer ‘Ecoboost’ over the lame-assed ‘InTech’ name used in on some V8 Lincolns like the FWD V8 Continental.

I assumed ( for an embarrassingly long time) that Pentastar engines probably had  five valves per cylinder, and that if you looked at the head from a certain angle, you would see some kind of star pattern. But no, the closest thing I see to any such pattern is the shape of t he block. Lame.

Ugh, “InTech”. Was that supposed to be some sort of reference to its having separate INTAKE cams ? That’s the best excuse that I can come up with .

I don’t know about that. FIAT at least has had quite a bit of experience with radials in their history.

Fiat A.74 14 cylinder radial.

The problem is that, like all Chrysler products, it’s not 5-star quality

Nah, it had a different name, phoenix , but there was a company of the same name that sued, so they used their logo instead.

Eco boost is a great name- for their regular cars. Not sure why they put it on their performance cars.

The “boost” part is fine, but I find the “eco” bit too eyeroll-inducing. I’m sure that this line of engines is much more efficient than older Ford engines in many ways, and thus one could argue that eco stands for economy . But that leafy logo is trying too hard to imply eco-friendliness , and the whole thing starts to smell too much like marketing bullcrap.

I took it as a way to sell turbos as efficient to the masses instead of just performance. Considering all the things they could have gone with I think its a success

it was originally named “Phoenix” (as in rising from the ashes of Daimler’s destruction) but there was a trademark issue.

it was originally called “TwinForce” in the 2007 Lincoln MKR concept . neither the name nor the concept made it to production. but the fact that the “TwinForce” was a 3.5 liter, twin turbo, DI V6 in 2007 should tell you how long the industry works on stuff before releasing it.

We need some more twin turbo v6s in the world. V6 is the most under-appreciated engine.

Whereas, this is aply named, and when I first saw the diagram it blew my mind: https://en.wikipedia.org/wiki/Napier_Deltic

Saw it on the BBC Four / Timeshift 2015 program The Engine That Powers the World:  https://www.bbc.co.uk/programmes/b06csy8c

Ford: needs an oval somewhere in the engine
Chevy: plus-shaped engine (X shaped radial maybe?)
Dodge: they’re screwed (or maybe they can make a slanted inline 2?)

It also had two intake runners for each cylinder, one short and one long with a butterfly to help switch between the two.

Deleting the Intake Manifold Runner Control is a popular mod for the early 4.6 DOHC engines, but it does affect low RPM response.

“Pentastar”

I think it’s a throwback to the old logo:

Otherwise, it’s just a cool meaningless word.

“It’s also kind of a one-time use thing. Now that Ferrari has a car that is essentially named “THE Ferrari”, all other Ferraris are allegedly less of a Ferrari than this”

I was just thinking... wouldn’t that mean that all other Ferraris are now technically Dinos?
