Golden Arrow Bus Services (GABS) – one of the biggest transportation companies
in South Africa – is committed to providing approximately 52 million passengers
yearly with a safe, reliable and sustainable means of transportation, in and around
the metropolitan area of Cape Town. The company’s fleet of 1 046 buses operates
along 1 300 routes providing an essential service to the local community. Voith DIWA
transmissions are fitted to 88 percent (918 vehicles) of the fleet vehicles and provide
extraordinary fuel economy.
SensoTop is a topography-dependent system equipped into approximately 70 per-

cent (633 vehicles) of the GABS fleet. The main benefits of this intelligent system are
higher fuel efficiency and lower cost/km. This is accomplished through the
intelligent adjustment of gear-shifting points to the inclination of the route. Bus op-
erators therefore reduce cost and improve their competitiveness.
The SensoTop system has not only seen huge success within the EMEA (Europe, of Golden Arrow Bus Services’
