People, may I present you with the VW Jetta.... In the US you can only get turbo four cylinders and a hybrid since the facelift. But, because we hate technological advancement, the environment, and we think that 2.5 is bigger than 1.8 therefore better, its still sold here.
To misquote Clyde Carson:

And i’m killing ya (the enviroment) hope i’m not offending ya”

My E92 decided it wanted to be a five cylinder about a month ago, a good experience it was not.

I test drove a current gen i5 Beetle awhile back and quite enjoyed how it drove. Another 5 cylinder VW is on the shortlist of cars I would like when I get a new vehicle.

While I’m not a turbo man myself I certainly see myself as a supercharger man and well, it remains true that there is replacement for displacement!.

While we can romanticize the 5cyls of years past, the current NA i5 that VW makes is not a good engine, its slow, complicated, unbalanced, and heavy. From a non-car person point of view the 1.8tsi is much better!

Yup. Doesn’t matter if it’s NA, TC or SC... more bigger=more better.

We could discuss this for hours to be fair. But I think that any engine over 4.5 L is overkill, as BMW, Mercedes,Ferrari, and Audi have shown you can extract 600 horsepower from smaller engines reliably and “ecologically” and really you don’t need more power.
I see the argument for lager, understressed engines (hell, I daily a 5.7 jeep and a 90hp 800cc bike) but as engineering gets more precise it becomes less of an issue!
I think that for the ICE motor to survive we need to focus on thermal efficiency and while downsizing may have little to do, it certainly helps to keep the engine’s weight and dimensions down!

It has to be cheap to build though, that must be the only reason it’s still in production.
In Europe the NA 5-cylinder in the Golf and its sedan sibling died after the mk4, if I’m not mistaken. So, way over a decade ago.

Increase efficiency, by all means. But even under those circumstances a larger engine will always outperform the smaller one.
Overkill? Maybe. Everyone needs a little overkill in their life.

Yeah, its probably cheaper to build and maintain(less piping than with the turbo 4).
But... its worse for the enviroment, but because SEMARNAT is ran by idiots, we don’t really care.
With Scott Pruitt (or whatever his name is) running the EPA I can see a future where the 5cyl goes back to the US and maybe even no catalytic converters!

Well, I think we’ll agree to disagree on the overkill!
But lets look at torque vs power, I agree with torque, but not with power.
A large engine will outperform only sometimes, because well, as you grow your engine so do the forces that it experiences.
If we think of outperform as to which is a better engine, we can look at say, a 6L straight six vs a 3L straight six, lets say both use freevalve and electric supercharging tech.
both are automatically balanced so you don’t need balancing shafts.
But lets look at other aspects. with the 6L you’d need stronger parts, larger injectors and e-chargers. the sheer energy that those liter-large chambers would release on the pistons would murder the crank and the block and virtually everything unless you made those very large which would make auxiliaries like ignition larger and that is an issue!
I don’t think you could get significantly more power than the 3.0, and even then, you’d need such bulletproof materials that the engine would be so heavy it would be practically useless in a car. I guess its all an issue of scale!
However.... a six litre six would get
TONS of torque
, i’m not even joking how torquey that engine would be! That’s why most heavy trucks have large straight sixes and not v8s. But back to power, the trucks have large 6L engines because they run slowly and therefore the parts are subjected to those stresses less often and can survive them, since they run slower they also have less inertia. I think you can make a good generalization by saying that with displacement torque increases.
BUT, if we look at a very interesting metric: HP per litre, its always smaller engines getting it, surely the 6.4 hellcat develops 707 HP, but Ferrari got almost 600 from the 4.5L Speciale v8! If you want to look at more pedestrian engines, volvo gets 158 HP/L out of a 2.0l 4cyl! if the hellcat got such hp/l it’d make 1,011 HP!
This happens because power is torque times angular velocity. The stresses that large torque figures subject engines to force engineers to make the materials heavier, which make them harder to spin, while yes you can spin a diesel truck to 9000rpm it would be pointless because most of the torque would be wasted spining such heavy crank and stoping the large, inertia festooned crank would be very hard and dangerous!
Its why motorcycles can run huge HP numbers with minuscule torque. Less stresses makes engines lighter which in turn makes them easier to spin, which in turn makes spinning quickly safer and more efficent.

The 1.8tsi is a great great engine. The 1.4tsi that the base Jettas come with...not so much.

I think that the Jetta is a missed opportunity, specially since they canceled the Jetta R. I hope that with its eventual migration to the MQB do also come great engine varieties and a hateful (but necessary) haldex option!

My 2013 Golf 2.5L is buttery smooth & has 218hp with a few mods.
58,000 trouble free miles later, I’m adding a turbo, it should make 350-400hp. I still haven’t spent “GTI” money.

I owned a 2008 Jetta S with a 2.5low, it wasn’t a great engine. It seemed course, wasn’t powerful and didn’t get good mileage.
It really didn’t do anything very well, it wasn’t terrible, just meh.
My 2010 VW CC 2.0T however was vastly better in every way, smooth, good power and great mileage if you stay off boost.
