Well there are these cone pulleys (STOP WHAT YOU ARE THINKING NOW). These pulelys arent being used as most cone pulley desigins put them to use.
These cone pulelys ride next to eachother as in the flattned tip of the cones almost touch eachother. There is also a V Belt riding in between these cones. The cones have grooves in them that do expand, but so does the V-belt.
There is another pulley at the other end that the belt also wraps around. The single pulley is the one that has the drive motor running it.

When the cones are pushed together, the belt has to ride up the cones becasue it has nowhere to go. as the cones are pushed together, the overall diameter of the touching point of the 2 cones grows and your gear ratio changes.

And that Nissan Murano with the powerplant under its hood, the 3.5 liter engine, with a CVT will be awesome.

1002 the CircuitRunners would love a CVT on next years bot, but that is if we can find one that can handle a lot of torque an one that will be reliable. We however will not build one if the game next year doens't call for one. Purpose over pimpness is a policy that we are trying to adhere to.
