Hi Gillis,
I have been following this thread with great interest since you first
posted. My recommendation? Buy two of the new style Lego motors. They are
very, very, very efficient. They will be much cheaper than an industrial
quality motor, and much lighter as well. I think you will be surprised at
the efficiency of the new motors in comparison to the old ones. The new
motors also have internal gearing, so you will be able to simplify the
geartrain on your car which will improve efficiency even further. Heck, I'm
so certain this will work I would lend you a couple of my motors if I lived
closer.

This isn't necessary. The load will be shared regardless. Its like a tandem
bicycle. You could actually try just one of the new style motors and the
performance should improve dramatically.
