[@leolouchios5574]

4 cylinders inline have always been the best engines.

[@Santor-]

This 2.0 500cc per cylinder doesn't apply in the US, and the reasons are the following; 2.5L non-turbo, is by far the most common 4 cylinder in the US, and it too, is "best", -atleast for the US. US does not have any hp or engine size based taxation. Hence a car is cheaper to produce, and sell, with a V6 or I6 for a set HP requirement, than a turbo4, which has many more components. 2.5 Litre is about as large as a 4 cylinder can go, before it creates excessive inbalance and vibrations. Larger 2.7 and 2.8L I4 exists, but either with severe vibration issues, or expensive balancing shafts, which makes a V6 the better (cheaper) option again. So why the 2.0 as a turbo engine and not a 2.5L? Engine blocks are developed as "families", or as a series, often spanning from 1.6L to 2.3L in the same basic engine block, for benefits of scale. The larger of the series is often stretched to the max; the remaining block material between the cylinder bores get very thin, not a problem on a non turbo 2.5, but once you add boost to it, its simply too little area to make a headgasket with enough material to keep the pressures in. It would blow headgaskets every which way from monday to sunday. So, once the plan is to have a 400hp 4 cylinder, you know your going to need a pretty beefy headgasket, and possibly also machine o-ring grooves in the block. Thats why they select the smaller displacement version of an engine family for the turbo version. Because this is the only version from the engine family with enough space to do so.This has always been the case, and one can follow this trend from the 70's euro turbos to this day. Physics doesn't become obsolete just because newer cars come along.

It's more likely that a 2.0L is accepted more commonly across the globe. Europeans are happy with it, not too big or small. The economy market in the US & Aus can flog a few. The Asian, African & South American markets can sell them as premium cars. An easier job selling 2.0L 4L in the US than selling a 3.5 V6 in the UK. That kind of thing.

Internal combustion engines will never fully die off honestly. There's already so many people aware of and saddened by their upcoming obsolescence that there's almost guaranteed to be heritage movements based around the IC engine well before the final car using an IC engine even rolls off the production line. And being a heritage movement doesn't mean new developments don't happen either, it just means they tend to be more hobbyist in nature although big things do happen as you can see with heritage steam locomotives: that Steam Train which Clarkson fired on TG (The A1 Tornado) was newly built in the 2000s using the old design and it's inspired other groups to try rebuilding "extinct" locomotives! I actually look forward to it because things being more hobbyist in nature tends to make them more interesting IMO, there's a lot of things that change with two examples being companies aren't quite as concerned about the confidentiality of their internal research when it's on now-obsolete subjects (ie. We'll likely see in-depth information/research on IC engines become public over time) or how cutting the amount of IC users effects the emissions problem. (eg. Engines like the 426 Hemi are an unsustainable engine if you're trying to put one in everyone's daily driver, but it's a completely different case if we're only talking about a few thousand petrolheads around the planet having one in a car they occasionally take out for special occasions)

And Mistubishi isn't alone in that. It's also been the case with the 2.0 Cosworth YB, the 2.0 Nissan SR20DET, and the 2.0 Toyota 3SGTE amongst others. Manufacturers had the right idea 20-30 years ago when these engines were conceived. Having flirted with other stuff for years, the OEM's are finally coming back around to 2000cc turbo four cylinders. Only now they're direct-inject, variable valve timing, and have much more sophisticated fuel management. They're more robust and refined, but they're following an old recipe.

It was so smooth (relatively), we had it for 6 weeks and 1500km, taking our two young children to the Ruhr, Wüppertal zoo (1975 remember - before zoos became abhorrent to civilisation) - and it returned 29 mpg, which considering it kept to 150 kph on the Autobahns, was very reasonable.

[@stuntmonkey00]

@@stevenp3176 Yeah, this is a much bigger reason that they didn't talk about. The secondary forces in an inline 4 are unbalanced, so engines bigger than 2.0L need balance shafts. But for economy applications, the reciprocating mass of engines under 2.0L is small enough that you can keep that in check without shafts. This is why the Honda D series 1.5L engines were small and peppy but buzzy, and the K24 engines were smooth but slower revving.

[@masterofThardus]

@@stuntmonkey00 Needing balance shafts over 2.0L depends on the usage. A big part of why automakers are going for 2.3-2.5L is because there's an increase in the importance of torque over hp in the modern car market. Mazda's 2.5 turbo, for example, makes max power at 5,000RPM, and doesn't rev over 6,000. Lack of balance isn't as big of a problem when you don't rev high.

I'm amazed by the B420T27 that's in my wife's 2016 Volvo XC90 T6 AWD. It's a turbocharged and supercharged 2.0L L4 that makes upto 316 hp (235 kW) at 5700 rpm and 400 N.m (300 lbf-ft) of torque between 2200-5400 rpm. For a car that size, to be ONLY powered by a 2L powerplant, that's pretty amazing/incredible. (The Mercedes M139 which makes 416 HP @ 6750 rpm and 500 N.m (369 lbf.ft) @ 5000-5250 rpm is just ridiculous how much power they've been able to squeeze out of a tiny 2L engine.)

@@cenciende9401 It is a consumer market rally engine from the Mitsubishi Lancer *Evo* . It was sold to public, but not exactly an every day car. The actual engine core is the 4G63 which was the core engine of all the Evos of that era. FQ-400 was a specific tuning package of it available from Ralliart (the Mitsubishi tuning and motorsports division). Thus available, but not like one would find it on normal everyday car shop floor. Soooo ehhh weird sports car specialty shop rare. Like you could get one, if you asked and paid Ralliart, but not something one would trip over in normal mitsubishi dealer. One would trip over more garden variety evos instead, with less powerful tuning setup. The 400 hp is not that weird, since most likely it was the rally engine with restrictor removed. The championship spec engines made 300 hp for all of the WR cars of that era. However that was with air restrictor. Everyone knew everyone's engine was capable more without the restrictor. Thus the FQ-400 was probably pretty high race tuned WR engine setup without the air intake restrictor plate. After all Ralliart was the shop also tuning the actual WRC team engines.
