More than 1,000 buses are now in service in the UK with Voith’s DIWA.6 gearboxes that have stop-start functionality, which reduces fuel consumption by up to 10%.
The first entered service around two years ago with National Express West Midlands (NEWM) in the Alexander Dennis Enviro200 MMC model and NEWM followed that with an order for 96 Enviro400 MMCs with stop-start Voith gearboxes.
With stop-start, the DIWA.6 can stop for up to 60 seconds without influence the start readiness of the bus.
