Another efficiency reference, from:
Jatco's job: Boost CVT efficiency, acceptance
Quote:
CVTs have plenty of room for improvement. The transmissions, for example, lose about 15 percent of their efficiency because of mechanical loss, compared with a mechanical loss of only 10 percent with dual-clutch transmissions, Usuba said.
Engineers will get there by reducing friction in the oil pump and bearings and by reducing the amount of oil splash caused by the gear bands as they slosh through the lubricant reservoir.
