Experimental engine installation

Recommended Posts

Here's a photograph of the engine bay for an experimental high performance model of a production car.

Who built it, and what's unusual about the engine?

Dude, that's weird. I don't even know what to make of that picture. It looks like a I6 put in there transversely, but the pulleys are on the side of the block, making it seem like the crank would be perpendicular to the engine. That's confusing as hell.

Believe me, it's simultaneously one of the weirdest and most clever engine installations I've seen in a long time.

Even with details of the engine setup it still took me a while to figure out what they'd done to get it all to work.

That's no flat six.

Looks like two inline 3-cylinder flatheads, each driving one front wheel. There's individual ignition, exhaust & cooling for each motor. I don't think they're neccessarily connected to each other; it must be that the belt drives are 'right-angled' out to the side in order to fit. What it's in I have no idea- something about the inner fenders says either '40s U.S. or '60s european. I await details of how the transmission(s) are set up...

I'm going to go out on a limb here and say that it is a rear-engined car from Germany and has an early version of a CVT or CVTs that each send power to one rear wheel. Could be used to provide power to each rear wheel individually in order to "throw" the car into a turn.

Just some first impressions.

Oh! That's the Saab 6-cylinder from the mid-1960s!

Is that right? A mid-'60s flathead?? Huh. Even MoPar dumped theirs after '60.

Those progressive saab engineers; I knew I should've given the 'born from jets' tagline more credit. :P

Correct, it's an experimental 6 cylinder SAAB from 1959. The engine is installed in the front of a lightened 1958 SAAB 93.

Now for the tricky part of the question ... "What's unusual about the engine?"

(and BTW, it's not a flathead)

You definitely "should've given the 'born from jets' tagline more credit". On a speed test on an airport runway, this tiny 'born from jets' car did 196 km/hr before they had to back off when it's aircraft influenced aerodynamics caused it to try to leave the ground. :rolleyes:

2-stroke? People are thinking it's a flathead because they don't see anything involving a valve train, but that's really because there is none.

Yep, it's a 2 stroke ... but that's still not the "unusual feature" of the engine.

Here's a hint. The car uses a strengthened version of the standard SAAB 93 transaxle ... and NOS2006 was very close to having the correct answer.

It's very unusual to see a radiator behind the engine. Must have a serious cowl vent situation. That's what made me think it was a rear-engine car, because of airflow concerns... it seems with engine heat blowing back onto the radiator it would be that much harder to engineer an effective cooling system.

Once this is settled, James, could you please post more pictures of this little beast?

The later models of the replacement SAAB 96 had a lengthened hood and the radiator was relocated to the conventional position in front of the engine.

Have no fear, I'll post more images once this is settled.

But in the mean time, here's what a SAAB 93 looked like:

You've gotta be kidding... that's an early Subaru! :AH-HA_wink:

Ha, but yeah, that is a classic SAAB, for sure.

I'd have given credit for "an early Daihatsu".

SAAB occasionally fitted their prototypes with Daihatsu badging when they needed to do public road testing in Sweden.

Nah, that was a lame reference to Subaru's shortlived "retro SAAB" face, as seen on the B9 Tribeca, and in a toned-down form on the Impreza. I understand that with GM's divestiture, Subaru has abandoned that style.

I should have thought of Saab, I remember a bunch of 2-stroke Saabs screaming around the track at a vintage race, it sounded like a chainsaw race. :lol:

Does it have something to do with the way the transmission is mounted?

211426[/snapback]

Yes. The coupling of the engine to the gearbox, and the engine gearbox relationship is the really bizarre part of the setup.

It's completely in front of the front wheels, it looks as if it has it's flywheel between the two banks of cylinders,

is it a chain drive?

211429[/snapback]

It is quite possible that it has a flywheel between the banks of cylinders (though I'm not sure, and it could be an unused feature of the standard SAAB engine block casting), but it's not a chain drive. However, the engine assembly is mounted ahead of the axle line and the gearbox/transaxle is behind the engine.
