You will be able to buy one next year. Audi will be offering a new CVT on 
the A4 that can handle the full torque of their standard engine. They have 
a new design that uses what looks like a 2-dimensional drive chain. There 
are sideways links so the chain can crawl up and down a sort of  "gear 
cone" towithout slipping. My vague description is based on a non-technical 
article I read in one of the mainstream US car magazines.

Combine the CVT with one of the forthcoming 42 volt engine designs and 
you'll have a car with no gears, no timing belt (or chain), no camshaft, 
and no alternator. The valves will be solenoid operated which allows 
infinitely adjustable cam timing. The starter motor windings will double as 
the alternator. Imagine changing your "virtual" camshaft profile by 
plugging your laptop into the OBD port and dialing in a longer duration. It 
makes me feel old. ;{)
