Proterra, a leading American electric bus manufacturer, recently unveiled a groundbreaking dual-motor powertrain system and introduced its first all-electric bus model in collaboration with Van Hool, a renowned European coach manufacturer. This innovative system marks a significant step forward in the evolution of electric public transportation.
The new powertrain features two high-performance motors that deliver a combined output of 510 horsepower, allowing the Catalyst bus to accelerate from 0 to 20 mph in just 4.5 seconds. With this technology, Proterra's buses now offer an impressive range of 1,100 miles on a single charge, making them ideal for long-distance urban transit applications.
The company announced these advancements at the American Public Transportation Association (APTA) annual meeting on October 9, 2017. According to Proterra, the DuoPower system not only boosts propulsion efficiency by 26% but also outperforms traditional 35-40-foot diesel buses by twice their performance level. Additionally, it surpasses competing electric buses by 72%, offering a compelling solution for transit agencies seeking reliable and sustainable options.
In addition to performance improvements, the new system enhances durability and reliability, which are crucial factors for public transport operators. The design focuses on long-term use and minimal maintenance, ensuring cost-effective operations over time.
Proterra is currently working with Van Hool to develop new models, including the CX45E and CX35E, which will be equipped with the advanced powertrain technology. These models are based on existing diesel platforms, allowing for a smoother transition to electric mobility. Both companies expect the first units to be delivered in 2019, marking a major milestone in the global shift toward zero-emission transportation.
With this partnership, Proterra is expanding its presence in the electric bus market and reinforcing its commitment to innovation in urban mobility solutions. As cities worldwide look for cleaner and more efficient transit options, Proterra's technologies are poised to play a key role in shaping the future of public transportation.
