The drive shaft is in a tunnel on the extreme right side of the cockpit

Here's a bigger problem with building a low slung car though. Modern engines are just too freakin tall. You either end up with a poorly proportioned car or 1/3 of the engine sticking up through the bonnet.

You may be able to build a low profile car with a Subaru boxer engine, but I'm not sure. Better minds than mine need to chime in.

Pretty tricky rear suspension. Upper A arm of two different lengths. I'm pretty sure I would avoid that set-up even though Sir Eric came up with it.

I already have the engine, a Nissan DOHC, so the car will be built in proportion to that...

A Subaru Engine would not fall into the LoCost category!

Agreed, I was looking at that as well.

I am just trying to get some ideas...

Here is another great example:

Looking at these Photos, I wonder if it uses an asymmetric Rear Axle:

That engine looks like it is aimed to the right....

The photo from the lower rear looks like the diff is in the middle...I wonder if it has a chain drive or belt drive or some such to transfer the power from an offset drive shaft to a central differential (and if that isn't how they did it, it might still be a good way to deal with the issue). But my main wonder here is, since that car predates constant velocity joints, doesn't it have crazy driveshaft vibration with the engine and axle flanges at two different angles? That must have been back when the tough guys used to race.

I am working on my version of the Mercedes W196 open wheel car. It will be a single seat with open wheels.
The W196 used an inline 8 leaned over to the right. A PTO came off the center of the crank between cylinders 4 and 5. That PTO drove the magneto, oil pump, and spun the drive shaft.
The driver sat with his legs apart and the shaft ran under the left leg, under the left axle, and to a rear mounted 5 speed tranmission feeding a DeDion axle.


I've got every scrap of info I could scrounge on the cars and will finish the drawings on mine after I land the power plant.

those are patterned after Watson Indy roadsters of the 1950s. look a bit "CGI-rendering"to me.

looks nice out there in that apocalyptic wasteland. best use of a Speedway Motors track roadster nose ever.
