They will inevitably find their way into trucks when they can fulfill their promise _and_ survive in truck duty. Nobody will commit based on a sample of a mere one technology demonstrator vehicle.

RE: Infinitely Variable Transmission
What problem does it actually solve that the current myriad alternatives do not? Comapring your efficiency against a conventional 4 speed auto with TC is a bit of a bad sign, I don't think they are even sold in first world countries any more. My rather boring diesel car has a six speed auto with a pair of dry clutches, I wonder how its efficiency compares with that?

Technically you have a valid point. An IVT would have an infinite ratio range in both forward and reverse directions. Most of these devices are more correctly described as continuously variable over a defined range transmissions, or CVODRT's.

Isn't something like that done in certain hybrids using the electric motor?
RE: Infinitely Variable Transmission
That solution was first proposed in the early 70s and they even built one car.
