We try out the simulated manual transmission program Toyota has developed for EVs, along with other simulated powertrains, and it's convincing.
Using similar techniques, Toyota created another prototype vehicle, in this case a Lexus RZ, that can simulate multiple different powertrains. The three vehicles, in addition to the base RZ, were a Toyota Passo economy car, the Toyota Tundra and Lexus LFA, each with corresponding numbers of "gears" up to the Tundra's 10-speed. And again, the simulations were carried out with different programming to limit torque application based on gas engine power curves. Acceleration would be cut at specific times to simulate the automatic transmission shifts. An onboard speaker with recorded sound would help complete the illusion. Really impressive was the fact that it would "downshift" at times when demanding more acceleration, and the roughness of the "shifts" would vary based on throttle input and "rpm." Again, it was all fascinating and convincing.
