NTop Engineering Inc.


Company profile
We, NTOP Engineering Inc. have developed "DGVT(Dual-motor Gear-meshed Variable Transmission)" powertrain system with the goal of "Double The Range of 1st generation EVs." The most advanced feature of DGVT is that unlike existing EVs combing one large motor with one fixed gear ratio reducer, the DGVT system uses two small motors that are 1/3 to 1/5 the size, so that the speed and torque of each motor are combined. It is an innovative patented system that allows for multi-stage gear shifting according the driving environment depending on the difference in the speed and torque of each motor.
In October 2024, we have tested in the field of KATECH(Korea Automotive Technology Institute) by DGVT applied electric cart and proved more than double the range. Now, we would like to make our proposal for the core technology of 2nd generation EVs which will fullfill "Better Range & Safety", beyond the limitation.
