Solaris Presents Second Generation of Hybrid Buses
Solaris has delivered the first examples of the enhanced, second generation of the Urbino 18 Hybrid city bus.


The new Solaris Urbino 18 Hybrid city bus.

It uses a smaller diesel engine, resulting in lower fuel consumption and better operating efficiency. The first of the new Solaris hybrid buses have been handed over to customers in Bremen and Hannover. Further Solaris Urbino 18 Hybrid for customers in Germany and Poland will follow over the next months.

Two years after the premiere of the Solaris Urbino 18 Hybrid, Solaris Bus & Coach has significantly enhanced the drive train of the environmentally-friendly hybrid bus. It now uses a smaller diesel engine, which is aided in its work by the electric engines of the hybrid system. Offering 178 kW at 6.7 l capacity, the new diesel engine is even more fuel-efficient. Independent tests carried out on the new hybrid have shown the fuel consumption to be almost 24% lower than on comparable conventional diesel buses.

Development honours the commitment of hybrid bus customers

Solaris hybrid buses have been built since late 2006 and are running in the German cities of Dresden, Leipzig and Bochum as well as in Lenzburg in Switzerland. Regular passenger operation in these places has offered varied and demanding challenges for the Urbino 18 Hybrid, from which Solaris Bus & Coach has been able to gain valuable experience for the further development of hybrid city buses.

The original 243 kW (330 PS) diesel engine proved on occasion to be too generously proportioned for everyday operation. This resulted in the aimed-for reduction in fuel consumption not being fully achieved. Furthermore, although the placement of the drive train in the front section of the bus offered a significantly better weight distribution, operators favoured a more traditional arrangement. Operational experience was key to the further development of the Solaris Urbino 18 Hybrid. The process takes a big step forward with the delivery of the first second-generation examples, but is by now means at an end as Solaris Bus & Coach continues the development of hybrid city buses.

"We would not have been able to follow this route without the commitment and experience of our customers. We are indebted to them for their support in the development of sustainable mobility," said Solaris CEO Krzysztof Olszewski, honouring the contribution of the first customers of the Solaris Urbino 18 Hybrid.
