Daihatsu’s whole advertising and marketing phrase for its D-CVT is Twin manner CVT, as well as transmission first built its debut together with the DNGA System Along with the fourth-era Tanto kei MPV back again in July 2019. At enough time, the corporate claimed the D-CVT was the earth’s 1st break up-equipment CVT program that mixes belt travel by using a gear generate, causing improved gas efficiency, acceleration feel and quietness. The Raize, which shares the identical transmission, was publicised as being the the quite to start with Toyota design to utilize D-CVT technology in 2019.
