Increasing challenges on reducing fuel consumption has opened the new directions in Powertrain technologies. The example of such technology implemented in geared transmission is the usage of novel type of gears with 3D point system of mesh engaging which was invented, patented and developed by Alexei P. Popov. The paper identifies the milestones of R&D that were undertaken to create the new type of geared transmission. Using the Winkler hypothesis Alexei P. Popov has developed and designed new type of point contact which made possible to lower a contact stresses in comparison to the values of a contact stresses for teeth having linear contacting interaction. The new shapes of tooth were invented and the methodological tools were developed for engineers providing the formulas for design and forming geometry of tooth with high stress capacity.
