New Car

If you have $USA50,000,000.00 to invest, call me! I have the plans.

I have a factory, too.

I suggest you copy Tata motors (and other non-American manufacturer's)

"Sporting a 175 cc engine, the Sitara is an open top city-cart. The car runs on petrol, has a 10-litre fuel tank and a four speed manual transmission. It can achieve a top speed of 60 kmph."

Why not go electric?

At 6 foot 3 inches tall and a muscular 250 pounds small and comfortable have never worked well together for me.

Moist modern liquid cooled motor cycle engines could easily be set up to power a small vehicle. My brothers bike has about 80 HP and is very small. I have seen many homemade dune buggy and go cart type vehicles with motor cycle engines that worked very well.

They are cheap and easy to make too! Just don't put all of that useless crap on them like every other mini vehicle manufacture seems to think they need to do and the manufacturing price will stay low.

The trouble is torque. Bike engines make high horsepower from high rpm, not ideal for a car. There's a dozen bike powered cars here

Then you have a drive problem. Most bikes are chain drive. I recall a VW Golf with twin bike engines, one on each rear wheel. Very fast but I imagine it drove like it was on ice.

And don't forget, bikes don't have reverse gear!

I Never said it had to keep the same transmission! And a few of the runt cars I have seen push a 10K RPM red lines just like a motor cycle.

Granted yes more gear reduction is needed for that high of RPM to be converted to torque but thats not a big deal.

As far as my understanding of the physics of mechanical power goes, I believe 50 Ft/lb at 10K rpm is the same horse power as 500 Ft/lb at 1000 RPM.

One advantage a modern micro compact car has is there are full hydrostatic drive transmissions now that can easily couple to high RPM engines and still provide very high drive line efficiency and long life spans.

The all terrain track vehicles (tracksters) had full hydrostatic drive systems a few decades ago and they had the drive pumps being directly run right off of the high RPM 2 cylinder 2 stoke engines. I have worked on them and been familiar with the basics of them for some time and they produced surprisingly little heat in the hydrostatic system even while being pushed hard.

A large amount of construction machinery has hydrostatic drive systems as well and they have proved they can handle the high horsepower while maintaining high power transfer efficiency with high life span capabilities long ago. It always rather surprised me that the technology never fully caught on in vehicles.
