TotalEnergies launches dedicated hybrid transmission fluid for Great Wall Motors

TotalEnergies and Great Wall Motors (GWM) has developed a tailormade fluid, Quartz EV-DHTF2, for GWM’s latest “L.E.M.O.N.” Dedicated Hybrid Transmission (DHT). This highly integrated, high-efficiency, the multi-mode gasoline-electric hybrid system features dual-motor hybrid technology, which achieves a perfect balance at all speeds and in all scenarios between high efficiency and high performance. This development was made possible thanks to a strategic Research and Development (R&D) partnership.

Great Wall Motors, China’s leading car manufacturer, is a key player in the development of
electric vehicles. As a pioneer in electric vehicle fluids, TotalEnergies has been actively
supporting GWM in the development of new driveline technologies for many years. The launch
of this new product, Quartz EV-DHTF2, dedicated for the “L.E.M.O.N. DHT” system, is an
embodiment and a milestone of this strong collaboration.
It adds a new brick to the Quartz EV Fluid range and is customized to meet GWM’s needs on
its DHT application. In addition to gears & bearings lubrication, Quartz EV-DHTF2 also offers:
– excellent Fuel Economy performance;
– optimal temperature control for the hybrid transmission, especially the electric motor;
– protection against shortcuts and static electricity;
– excellent compatibility with copper coils and polymer materials used in the electric engine.

These properties ensure the proper functionality of the DHT and maximize the durability of the
components.

“This new product, Quartz EV-DHTF2, is the result of a successful partnership between GWM
and The Lubricants Division of TotalEnergies, through collaboration in research and
development. Thanks to such partnerships, TotalEnergies is building a solid foundation of
knowledge and expertise in hybrid and electric engines year after year”, said Jean Parizot,
Vice President Automotive at the Lubricants Division of TotalEnergies.
