Voith Turbo’s DIWA.6 Transmission Helping to Reduce Emissions in San Antonio

Voith DIWA.6 offers a smoother ride and fuel savings
York, Pa. (May 3, 2017) – As the demand for cleaner and more fuel-efficient mass transit vehicles increases, VIA Metropolitan Transit in San Antonio is partnering with Voith Turbo’s DIWA.6 automatic transmission to reduce NOx emissions and increase fuel savings.

VIA is in the process of converting its fleet of diesel buses to cleaner compressed natural gas (CNG) and has opted to install the Voith DIWA.6 automatic transmission. Voith has begun making deliveries from its York, Pennsylvania location. “VIA’s conversion to an all-CNG fleet is where the rubber meets the road for our commitment to drive innovation and connect our region with a cleaner, ‘greener’ future,” VIA President and CEO Jeffrey C. Arndt said. “Well-built, fuel-efficient vehicles will help us provide environmentally sustainable transportation for our region.”

The DIWA.6 transmission benefits include:


  • a long first gear for smoother acceleration and a smoother ride for passengers;
  • less shifting for less wear and higher reliability;
  • coolest-running CNG transmission in the industry;
  • a full-flow cooling circuit that allows for 100 percent of oil to be cooled and filtered; and
  • optimal performance, even in extreme climates.



The DIWA.6 comes equipped with Voith’s Hydrodamp Coupling which absorbs and isolates vibrations, protecting the transmission and the engine while also allowing for lower engine speed operation without noise and vibration. This increases the overall drivability and operation of the vehicle while also making it a quieter mass transit option.

San Antonio is now the 11th city in North America to start converting their transit bus transmissions to Voith Turbo’s DIWA.6.

“VIA Metro Transit has been a great partner and understands the benefits the DIWA.6 transmissions will bring to VIA’s fleet,” said Dan Hollenbach, Region Manager, Commercial Vehicles, Voith Turbo.
