Improving the efficiency and extending the life of the drivetrain system.
Unlike cars with combustion engines, which require a multi-speed transmission, the e-motor in an electric vehicle produces a consistent amount of torque, almost regardless of RPM. As a result, the majority of EVs feature a much simpler single-speed transmission, with an option for neutral and reverse gears too. That being said, it’s likely that – as the market’s offering of EV technology evolves – electric cars with multi-speed transmissions will become more widely available.
It’s important to note that the role of e-transmission fluid is even more vital in an EV. That’s because the demands on e-transmissions are more severe than conventional transmissions, with maximum torque delivered at low speeds and the increasing integration of electric motors. And e-transmissions are now evolving from a separate electric motor and e-transmission, to a combined system demanding more from the e-fluids.
Future EV motor-transmissions can be enhanced by adding a shifting device to reach higher speeds, operate with synchronizer systems at high speeds and loads and to enable the eMotor to drive in the most efficient range.
Castrol Wet Plus Transmission e-Fluid’s specially-developed technology, with its optimised friction levels for synchronizer systems and clutches, allows efficient shifting under high loads and speeds and to operate the eMotor in the most efficient range.

EV motors can generate extremely high torque at low speeds. The transmission element has to deal with more than double input speeds from the motor and the motor unit operates immersed in the transmission fluid.
Castrol Wet Transmission e-Fluid’s low viscosity formulation is specifically developed to deliver low electrical conductivity, enhanced system protection and helps the e-motor run cooler enabling it to operate at high efficiency.

EV motors can generate extremely high torque at low speeds. The EV transmission must deal with this and can face more than double input speeds from the electric motor, putting the lubricant under immense stress.
Castrol Dry Transmission e-Fluid helps overcome the challenges the drivetrain system faces by providing enhanced protection, reduce viscosity loss and fast release of entrained air.
