Three Mercedes-Benz hybrid buses now in service at Stuttgarter Straßenbahnen
  • The first three hybrid buses in Baden-Württemberg
  • Electric operation with hybrid drive system
  • 20% to 30% lower diesel consumption and CO2 emissions
  • No emissions and practically whisper-quiet operation on some sections of routes
  • One the world's largest lithium-ion batteries in use in a vehicle

Three Mercedes-Benz hybrid buses now in service at Stuttgarter Straßenbahnen

Following successful practical trials in December 2009, Stuttgarter Straßenbahnen AG (SSB) has now brought three Mercedes-Benz Citaro G BlueTec Hybrid buses into service, with a further two vehicles due to be delivered later this year. The environmentally-friendly hybrid bus met with an excellent response from passengers during last year's week-long practical trial, and also demonstrated significant fuel savings on the inner-city 42 route, one of the area's most demanding routes with the most varied topography.

Today Hartmut Schick, head of Daimler Buses, handed over the three articulated hybrid buses to Wolfgang Arnold, board member of Stuttgarter Straßenbahnen, in the presence of Dr. Wolfgang Schuster, mayor of the provincial capital of Stuttgart, and Andreas Renschler, board member of Daimler AG with responsibility for Daimler Trucks and Daimler Buses. "Thanks to these new hybrid buses, Stuttgart is once again making significant steps forward on the road towards sustainable urban mobility. I am pleased that we are again able to demonstrate our leading role in this area. Stuttgart makes the ideal testing ground for new forms of transport and new technologies: what proves to be successful here usually goes on to be a bestseller elsewhere. I am extremely grateful to Daimler AG for the future development potential they are offering along with their creativity, and above all for co-operating with the city of Stuttgart in the field of mobility", explained Dr. Wolfgang Schuster.

At the official handover, Andreas Renschler said: "We are extremely pleased that our long-standing customer from Stuttgart will be making use of the articulated hybrid buses from Mercedes-Benz and their cutting-edge technology in Stuttgart, and as such these are the first buses of this type to be brought into service in Baden-Württemberg. For decades, SSB's bus and coach strategy has been consistently geared towards trialling or implementing new technologies, and we are all the more thrilled that we have been able to support them in this area".

Mercedes-Benz Citaro G BlueTec Hybrid

The Citaro G BlueTec Hybrid is the only hybrid bus in existence today that can travel for stretches solely on electric power without using its diesel engine, approaching bus stops without making hardly any noise. After stopping, it continues in a similar fashion at several more stops along its route, without the usual loud engine noise one expects to hear from a bus. The drive system is provided by four electric wheel hub motors, which get their power from one of the world's largest lithium-ion batteries to be used in a mobile application. This power is generated via braking, for example when driving downhill, and if necessary can also be produced via a generator driven by a diesel engine which is comparatively small for this class of vehicle. Experts refer to this concept as a serial hybrid drive.

Hartmut Schick is confident about the long-term success of the hybrid bus from Mercedes-Benz: "I expect ten to 15 percent of new orders for city buses to be made up of such hybrid drives by the year 2015. As always, SSB is leading the way in this area."
