Two engines?

Guess you could try rigging up 2 geo 3-bangers in a compact truck for a 6-3, inline or vee.

I have thought of leaving the car stock and then using a small Briggs and Stratton driving a separate wheel set up like a single wheel pusher trailer. I have already purchased an 8 hp Briggs and a 14 inch motorcycle wheel. This would be my version of displacement on demand. I think the 8 hp engine could sustain a little over 45 mph on the level. My car glides very well. A little push could really extend the glides.

I started thinking along this line because I was wondering how much fuel 100 amps at 72 volts could replace in a 30 mile round trip commute. The engine would just be a test mule to prove the concept before I dropped the big money for the motor, controller, and batteries.

Realistically I have enough engineering to know that pay back might never occur even for the cheap version. It was just a thought experiment but when I was buying a 2 hp engine for a bike trailer I came across an 8 hp engine. I got a 15 year old engine that had never been started for what I thought was a very reasonable price.

I've seen a Rabbit Pickup truck that had the standard front wheel drive, and another engine that drove the rear axle, can't remember what it had in the back, and they had a whole box of CV axle joints that had been snaped while trying to drive both sets of wheels at the same time, however some vehicles used in auto cross racing use a simaler idea, altho I suspect that they use a freewheel set up simaler to how a 2 wheel drive motorcycle works, one axle coasts, a set up could be done on a small 4 wheel drive vehicle like a Honda WagoVan, or Subaru Justy.
