(Boucherville, QC) Prestolite E-Propulsion Systems (PEPS), a 50/50 joint-venture between Prestolite Electric Beijing Limited and TM4 Inc., receives a multi-million dollars order from Foton, one of China’s largest bus manufacturer, for more than 250 SUMO HD electric powertrains. These systems will equip 12 meter and 18 meter buses. PEPS has been working closely with Foton over the last 18 months, a critical trial period under which the SUMO HD systems have outperformed the competition, showing outstanding efficiency, performance and reliability.

The following order is in addition to a recent order for over 100 SUMO MD and HD powertrains for BLK, announced last July. Read more

Developed for performance and durability, the TM4 SUMO systems are optimized for medium-and heavy-duty electric and hybrid vehicles such as 6-18 meter buses, delivery trucks, shuttles, tow tractors and more. By allowing direct-drive operation, the TM4 SUMO systems reduce the powertrain’s complexity and cost, allowing for a simple, efficient and low-maintenance solution. A direct-drive system yields over 10% efficiency gains throughout the driving cycle, representing an equivalent gain in battery usage. Some of TM4 SUMO systems are offered with a double-ended shaft option, allowing for easy integration in many hybrid-electric powertrain architectures.
