A possible solution to worn out drive belts and gear wheels is a solution that the Dutch came up in the late 70`s.
Does anyone remember the DAF 55.
It had no gearbox as such.
The gear lever selected forward or reverse.
All the work being done by a rubber V belt and an expanding pulley wheel.
The problem at the time was the longevity of the V belt and time to change and set up the pulley wheel.
The expense of frequent belt changes made the car unpopular although the car was cheap.

I remember an episode to Top gear quite some years ago,The problem of broken V belts was solved by making them out of steel.
On the particular episode of the program, they fitted the new set up to a Formula 1 car that David Coulthard drove.

With this set up, the benefits are large.
The possible weight saving in the region of approx. 100kg.
Made of no gear box, very small tunnel in the car giving tons of leg room. No worn out rear drive wheel and longer life of the final drive.
As the car could possibly now weigh less than 450kg Taxation and regs regarding the class of vehicle will change.

The DVLA classes three wheelers at this weight as motorcycles.

I have sent this to Morgan.
