Encyclopedia Hoonatica: Even Odder Engines

By Peter Tanshanomi Aug 16, 2010


The vast majority of cars have an even number of cylinders—2, 4, 8, etc. Much more rare are cars with an odd number of cylinders in the engine bay. Very few cars indeed have been equipped with both an even-cylinder engine and an odd-cylindered version. The Audi 100 and GM’s Colorado/Canyon pickup are two fairly well-known examples available with both 4- and 5-cylinder engines. How many can the Hooniverse Hive Mind come up with? There are at least a few more, including one fairly obscure one I am keeping to myself in order to test your skills. (Hint: the two engines needn’t have been available in the car at the same time, and don’t focus exclusively on 5-cylinder blocks.)
As always, read through first and avoid duplicate answers.
DIFFICULTY: You only thought last week’s convertible pickup question was tough. Okay, there are a lot more correct answers than I was aware! Shows me not to attempt to go up against the Hooni-Hive-Mind.

    1. I guess we can throw in the Suzuki Swift and all derivatives (Holden Barina, etc) here as well.

    2. I was totally going to say that. It's a rough engine overall, but damn if that G10 Suzuki motor purr when running right. That and it got 50mpg!

  1. Acura Vigor 5 and 4 cylinder motors.
    Current-gen VW's with 4 and 5 cylinders.
    Jeep FCs available with a 3-cylinder two stroke Cerlist diesel and various 4 or 6 cylinder engines.

  2. The H3 (shudder) can come with an I-5 or a V8, and the Passat, Golf, and Jetta were variously offered with a VR5 or I-4 from '97 to 2000.

    1. Volvo is the poster child for the 5-cylinder design thanks to the modular "white blocks". Same lumps have found their way into the new Ford Focus and back in the 90's they were available in Eagle Premier's distant nephew, the Renault Safrane as well.

  3. A day early for two wheeled Tuesday, I submit the following:
    Triumph Daytona (3 cylinder); Triumph Daytona 1200 (4 cylinder)
    Triumph Trophy 900 (3 cylinder); Triumph Trophy 1200 (4 cylinder)

      1. I have said "but only the ForFour had a four for production" ten times now, and the entertainment value has still not gone down.
        /easily amused
        //yes I have ADD
        ///I have a red car

  4. The Isetta started life with a 2-cylinder engine, went to a single when BWM started making them, later to be replaced by another two cylinder.

    1. Reminds me somewhat of the Lloyd 650. It was essentially a three-cylinder, but only two cylinders drove the engine. The third was centrally located and was gravity fed raw fuel, and then through inertia it would pressurize the fuel, feeding the carburetor, which would inject atomized fuel into the other two cylinders. So the third cylinder was in effect a dumby cylinder serving as a fuel pump and, to some degree, a primitive supercharger.

    1. Wha…it's a modern-day (and shrunken) Napier Lion! With carbon fiber intake trumpets and tubular headers! Thank you, sir, for pointing the way to this awesomeness.

  5. Daihatsu Charade started out with a 1.0 3-cylinder and moved on to a 1.3 4-cylinder.
    The first generation Honda Insights also had 1.0 3-cylinder and moved on to a 1.3 4-cylinder. At least the gas half of the propulsion.
    Mercedes Benz W123 300 class had both 5-cylinders and 6-cylinders. The W201 190 class had 4, 5 and 6-cylinder engines.

    1. The first and second generation Insights are the same car in name only. Or are you saying that you could get a Gen1 Insight with a four-banger at some point? That would be news to me, but I'm not exactly an expert on that car.

  6. Not a car engine, but the Commer/Tilling-Stevens 3 cylinder horizontally opposed 2 stroke diesel truck engine was pretty odd.

  7. Weird, the other day a Chevy Colorado with a somewhat loud exhaust passed by my house and I noticed the odd sounding exhaust. I forgot that they used the inline-5 engine, and I thought to myself that this would probably end up being a Hoonatica question. I was right!
    My contribution was going to be a 300D Mercedes but as always I can't get to this thread in time to post anything.

  8. Suzuki, in 1977, offered both the GT550 two stroke triple and the GS550 inline four. They're bikes and I know it doesn't really apply to this topic, but there it is anyway.

  9. I love that as of right now, a post about odd-number engines has double the comments as my Camaro review. You guys rule.

    1. That was… strange. And quite self-flattering on the part of the pastor. If driving skill means you're possessed I guess Ayrton Senna is the devil himself?

    1. Wow, nice little archive image. I first saw an Innocenti in town when I was little, don't think I've seen one since. I remember being amazed when I found that the underframe was pure BL Mini. Oh, and I'd kill to own anything with a De Tomaso badge

    1. Looks like the off-spring of a Bug and a Euro-van.
      On the plus side, those hella-skinny tires must give awesome traction in the snow.

    1. While I don't think that it counts, since it wasn't a factory option, it's still cool to see my car as a response to this question.

  10. Landrover Discovery Series II, your choice of V8 gas or 5 cylinder diesel in most markets outside North America. I think it was diesel only in some areas. The Landrover Defender also gets in since the same TD5 diesel as the Discovery was used from 1999-2007 while the older (94-98) 4 cylinder 300tdi was available on "third world" spec vehicles, plus I think the South African Defenders with the BMW M52 six lasted until at least 99 or 2000.

  11. I want to second Mr_Science in loving these posts.
    My hat is off to Tanshanomi for the idea, and to everyone else for pooling and panning obscure knowledge.
    Much later, following some serious internet mining…
    Single or twin engines:
    The final Mark G Bond Minicars
    Scootacar
    Spainish David cyclecars
    Maytag Toy Racer
    Two or Three Cylinders:
    >1984 Mitsubishi Minica
    Suzuki Fronte 7-S
    Two, three AND four cylinder
    original Suzuki Jimmy
    Three or four cylinders
    Audi A2
    Daihatsu Mira
    Daihatsu Move
    Maruti Alto
    Mitsubishi Town Box
    Mitsubishi Toppo
    Opel Agila
    Third generation Subaru Rex
    Multiple generations of Volkswagen Lupo
    (and SEAT Ibiza and Skoda Fabia)

    1. i also do not think anyone has mentioned the Mercedes Benz W123. it came with 4,5, and 6 cylinder engines.

  12. This falls under the sort-of category.
    Lloyds, the British one, not the German one, originally came with a Villiers single-cylinder motorbike engine. Later, they moved on to using an engine of their own design, which was a two-cylinder. Except it had three cylinders. The third cylinder was smaller and centrally located. It was fed, by gravity, raw fuel. Then, by action of the starter motor and once running simply inertia, it would pressurize the fuel to feed the carburetor, which would then provide atomized fuel to the other two cylinders. So the third cylinder was a combination fuel pump and primitive super charger.
    So, from 1 to 2 that was really 3.

  13. I'm surprised no one's mentioned these current choices…
    VW Golf/Rabbit/Whatever has a 2.5L I5… but then there's the 2.0L turbo in the GTI and a 2.0L diesel (I think)
    Ford Focus (non-USA) with 4 cylinder power for regular models and a Volvo 2.5L turbo I5 in the ST, RS, and RS500

  14. Okay, the one I was holding in reserve? The Honda Today kei car, available with a 2-cyl from '85 to '87, then with a 3 from '88 on.

  15. I knew I forgot something… Volvo 200 series was also available with 5 and 6 cylinder versions of the VW diesel engine developed for the LT panel van.

  16. The current Volvo S40 and C30 are available with i4 and i5 gas engines AND i4 and i5 diesel engines.
    The current VW Polo and VW Golf have turbocharged i3 and i4 engines, both i3 and i4 are available as diesel and as gasoline. In the 90s the Golf also had 5 and 6 cylinders, with the antiquated i5 apparently still available in the US.

  17. okay… so… all the stuff i had in mind to suggest for this article are taken…. one joke (actually, sadly serious) offer i have is the 2.4 to 3.8 "straight 4 or Veee 6" gm offerrings that i can guarantee are misfiring on at least on cylinder… (whenever i feel like making the joke, because to do it every time would just be serious overkill) i say "hey, that car has one of those damned, dead reliable (normally GM) V5s! (or V3, depending on how bad… sometimes V7.. etc.)… "
    i feel the need to mention that the "great state of Indiana" (is a state, but not great) has no emissions or safety inspections for most vehicles (if there is a lapse in title/registration/application for salvage title, yes.. but otherwise… nope)
    all kinds of late 80s to early 2000 GM "custom" 'v5's running around here… and a lot of them have shed the weight of those cumbersome full sized rear tires… swapping 'em out for the more fashionable donuts!

    1. I think those donuts are for weight savings & increased performance – I get passed by 'em all the time on 465, and I'm no Captain Slow.
