General Motors has developed a prototype of its existing two-mode transmission (2MH4EV) specifically designed for front-wheel drive, plug-in hybrid vehicles. At the 2011 SAE World Congress, GM outlined the operation of this prototype transmission, claiming that the unit adds an input-brake clutch to the automaker's existing two-mode system that enables enhanced electric vehicle capability.

Daimler is currently working on a new hybrid vehicle engine that the company calls a transmission-integrated electric engine. As the name suggests, the setup puts the electric engine (motor) into the automatic transmission.
