A belt with teeth is far more productive than a chain. Chains are used on bicycles for their ability to change gear easily but the power is not as direct as a belt. The power on a chain must go through each link whereas a belt is continuous which is why motorcycle manufacturers like Harley D use belt drives.

In fact, belt drives will soon be on bicycles, they are trialing them now with new Shimano Bottom Bracket gear systems.

Made correctly with some CF weave, belts can last well up to 90k miles. before they possibly stretch or fatigue

The oil companies dont want this technology made because it would mean serious losses on their part therefore they do all they can to shut down any advancements in this area. Is rediculas really when we should be saving oil.

Wouldn't be as much at you think, oil is not just for making petrol

Where did you get this info from?
I work in the Oil/Gas industry and I would say you are about 120 years out at best.
Most of the worlds oil fields past peaked production years ago. And the amount of new fields is reducing all the time.

They get the info from the TV

well, the exige uses very little fuel comparitively anyway

Any where petrol can be bought in bulk, could be a millionaire in ..... 120 years!

Not true im afraid, if i remember rightly there about 60% efficient due to all the moving parts, a belt drive is much more efficient.

http://en.wikipedia.org/wiki/Driveshaft suggests 97% in optimum condition for a dérailleur system

Inverted tooth drive chains (e.g. HY-VO) are up to 99% efficient.

Toothed belt drives are generally somewhat more inefficient, but are quieter and have shock absorbing capabilities. V belts have much lower efficiency.

VW have a production car that does 100mpg i think

Dunno were i pulled the 60% efficiency from

odiously in my old age my memory is becoming less efficient.
Im guessing real world figures will be a lot lower for both transmissions sorts.

Seems strange using a chain and sprocket transmission on a vehicle thats been designed to be as efficient as possible.
