1. A variable transmission comprising:
an input shaft; a variator (CVP) comprising a first ring assembly drivingly engaged to the input shaft, a carrier assembly comprising a plurality of tiltable variator balls drivingly engaged with the first ring assembly, and a second ring assembly drivingly engaged with the tiltable variator balls; and a planetary gearset comprising a planet carrier coupled with the input shaft, a ring gear drivingly engaged with the second ring assembly of the variator, and a sun gear drivingly engaged with an output of a vehicle, wherein the variator is placed first in a transmission arrangement, wherein the variator controls the flow of power from a power source through the ring gear of the planetary gearset and is subject to the speed ratio of the variator, wherein the planetary gearset is configured to split power of the input shaft between the variator and a mechanical path going directly to the output through the planetary gear set.
