Engines available in every model
-
Reading @RazoE 's post https://opposite-lock.com/topic/76190/engines-available-only-in-a-single-model/6 made me think about model years where every car had the same engine. This feat is probably limited to lower production numbers. Please suggest some rules to widen the field. Maybe expanded to instances where a manufacturer used the same engine perhaps in different displacements, or when the same engine was uses in one segment of their line up.
(note the engine above is the B20 that replaced the original B18 that came with the car)
I was thinking about my old Volvo 1800 to kick things off. In 1967 I am pretty sure every Volvo car made used their B18 engine which was 1.8 liters and had 5 main bearings. The B18 replaced the B16 engine in 1962. In 1969 they added the B20 which was a 2.0 liter engine. Supposedly there were improvements in engine casting with less voids that allowed them to bore out the same block a bit more. Externally the B18 and B20 are the same dimensionally and have the same engine mounting brackets. The B20 has some extra doodads on it such as extra mounting bosses for the Motorola Alternator which was an upgrade from the B18 generator.I might only be thinking about the mainstream cars Volvo produced so perhaps I am wrong and there could be other engines.

@Albino-Kangaroo Chrysler with the Pentastar V6. I mean, Chrysler only has 2 models, but yeah
-
@RazoE This was actually my first thought since it's available in most CDJR products
-
@Albino-Kangaroo I'm always confused as to what we mean when we say "an engine". Like with Volvo, is the Volvo Modular Engine one engine, or like a hundred if we count all variants? Or do we count 4, 5, and 6 cylinder variants separately, but say that tiny changes in displacement or whatever don't matter? Does adding a turbo make it a different engine?

@Albino-Kangaroo Subaru 2.5L NA, Impreza, outback, legacy, forester, only excluding the ascent and wrx.
-
@RazoE The Pentastar! How could I forget. That is the only engine available for my Chrysler Pacifica. Technically the hybrid version gains motive force from extra electrical motors but it also has the same (but detuned I think) V6.

Also, I think the Hybrid version runs a modified cycle of some kind, but still the same basic engine.

@Albino-Kangaroo K-cars. For a few years there that 2.2/2.5 was standard in every Mopar vehicle except the M-body dinosaurs, the captive imports, and the full-size trucks.

VW and the 2.0t?
It gets confusing with more global brands because you can usually mix & match different markets to get an answer.
If VW built a school bus, in Europe they'd put the 2.0t in it.
Also gets complicated since most brands have some kind of EV now, too.

@Albino-Kangaroo "Available" is only constrained by your ability with a sawzall and welder...
But being more serious, what GM product of the 50s-90s was not available with some flavor of Gen 1 smallblock V8?

@facw I like picking and choosing rules so I would say go with what feels most fun. Background would be great too. A couple of weeks back there was a post about the V6 vs V8 Jag engine. I think that falls under same architecture but different casting. I would say any Honda K24 variant is a K24 even if one came with a turbo (but I don't think Honda ever added one).

@Albino-Kangaroo Reliant from 1995-2002, granted, they only had one model for most of that time, but the Rialto was still around for the first few years, so they did still have two for a little bit.
2022 Ioniq SE
1964 Corvair Monza -
@Bandit All of the front wheel drive ones. Though I think you could get the 2.8 V6 in almost everything except full-size cars/trucks at one point.
-
I think that in days of yore it was pretty common even at larger makers: Chevy with the "Six in the price range of a Four" years, Chrysler with the "Windsor" Six, Buick straight-eights, etc.
And of course there's the Model T, its spiritual successor the air-cooled VW... We're verging on an adjacent theme question, companies that made the same engine available in every model because they only had the one engine" (by choice or because it was all a smaller car maker could manage) here.
-
@Albino-Kangaroo 90s and early 2000s jeeps could all be had with the 4.0 I6. Pretty sure every AMC ever made could be spec'd with a version of the I6 as well, although displacement changed a bit over the years.
As someone else said the 3.6 pentastar is used in all chryslers, most dodges (hornet is new so 2023 and a few years back), half the jeeps and some RAMs too. They make a few of them...
-
@ranwhenparked Great find! I didn't know they kept making them for that long.
-
@Albino-Kangaroo My deep knowledge of vintage BMWs lives and dies with the 2002 and similar, maybe a little E9. However, I think all of the Neue Klasse cars used some variant of the M10. So in 68/69 from BMW it would have been an M10 or M30

@Albino-Kangaroo 2 put together makes a B36
!<img src="https://images.cdn.circlesix.co/image/1/700/0/uploads/memes/b36-54a85a397fa14.jpg" alt="Rare Volvo redblock V8!!! (B36)"/> never made it into cars but that woulda been sweet in an 18er 3600 coupe. -
@Dash-Doorhandle-and-Bondo What is bothersome is that the B36 was produced mid 50's with a crossflow head (intake air goes on one side, exhaust comes out the other side of the head), and the B18 B20 had reverse flow meaning intake and exhaust go in and come out of the same side of the head. Volvo mostly used a combined intake and exhaust manifold that helped on fuel atomization and probably emissions but made the carbs nice and toasty. Probably fine for Sweden but in hotter climates vapor lock could be an issue. It also made it more difficult to modify the engine for more power.
-
Like Volvo, I believe SAAB did a lot of single engine application for their platforms (granted, they usually only had several anyway). Must be a Swedish frugality thing.
-
@Ad-absurdum-per-aspera Agreed. I like that VW found something that worked based on what I assume is late 1930's engine technology and kept with it for decades.
Modern Subaru's are similar. They do have a couple different engines these days, but 10-15 years ago they probably had the same engine (with minor spec differences, excluding STI) in 80% of their cars.

@Albino-Kangaroo From the early 50s to the late 60s, every car with a Jaguar badge on it had an XK engine under the hood - that covered about a dozen models of saloons, sportscars and race cars. Came in four displacements and several varieties of cams and carbs over that period, but the same basic engine.

@іди-на-хуй-Влад-formerly-known-as-Distraxi Damn, those engines were around for a while. I plan to read the wiki page on those engines. It sounds like they nailed the design early on and get going with it. Great example.
