(PRESS RELEASE) HEIDENHEIM, 15-Jan-2025 — /EuropaWire/ — Voith’s DIWA NXT automatic transmission system is rapidly becoming a preferred choice for bus operators worldwide, particularly for intercity and regional services. This advanced system, which includes the company’s first mild hybrid transmission, bridges the gap between traditional diesel-powered buses and those utilizing alternative drive technologies.

For bus operators running scheduled services in rural areas, the DIWA NXT provides a cost-effective and efficient solution to enhance the environmental performance of their fleets. In regions where infrastructure for electric or hybrid vehicles is still under development, the DIWA NXT offers a practical alternative, allowing for improved sustainability without the immediate need for extensive investments in electric vehicle infrastructure.

The DIWA NXT transmission helps reduce fuel consumption significantly, especially on long distances and high-speed routes. With the mild hybrid system, operators can achieve fuel savings of up to 16% due to the central Recuperation Unit (CRU). Additionally, the integrated secondary retarder enables most braking operations to be performed without wear, reducing the strain on the vehicle’s service brakes. This combination not only makes vehicle operation more economical but also aids in reducing emissions and meeting environmental standards.

The system’s second overdrive gear ensures a smooth, comfortable ride, even over extended distances and at higher speeds, improving the travel experience for both passengers and drivers. Furthermore, the DIWA NXT proves highly effective in hilly terrain. Even buses with heavy gross vehicle weights—around 19 tons—can easily ascend inclines of up to 12% in second gear, a performance that exceeds that of conventional drive systems.

The DIWA NXT’s combination of fuel efficiency, smooth operation, and high adaptability to various driving conditions makes it an excellent solution for both intercity and urban transportation, offering operators a flexible and sustainable option.
