üstra expanding its Hannover fleet with 10 additional hybrid buses equipped with the Allison H 50 EP

Municipal bus fleets in Barcelona, Spain and Krakow, Poland are also adding more Allison-equipped hybrids

HANNOVER, Germany – After eight years and more than 5 million kilometers, üstra Hannoversche Verkehrsbetriebe AG is growing its fleet of buses equipped with the Allison H 50 EP hybrid system. A total of 10 new Solaris 18H buses will be delivered in 2017, with five in the spring and another five in the fall.

The Allison H 40/50 EP™ systems feature a two-mode split parallel architecture – a pure mechanical path and a pure electric path – to achieve the highest energy efficiency. The technology operates automatically as a series or parallel hybrid, improving fuel consumption by up to 25 percent over a typical bus. Additionally, its regenerative braking capability can significantly extend the brake change interval by as much as 350 percent.

Since 2008, üstra has grown its fleet to 27 Solaris Urbino 18H buses equipped with the Allison H 50 EP hybrid system. The buses primarily service city lines 121, 123 and 124. These routes are characterized by short distances between stops and low average speeds, circumstances where the benefits of the hybrid buses are most significant.

Allison hybrid systems may also be equipped with a customized electric distribution platform that provides power from the hybrid system to accessory components such as electric air conditioning, electric air compressors and electric power steering systems, offering further fuel economy improvements.

In addition to Hannover, more European cities are also expanding their bus fleets equipped with the Allison hybrid system. Transports Metropolitans de Barcelona (TMB) currently operates 15 Euro 6 Solaris Urbino 18H. With the delivery of 25 additional Allison-equipped Solaris buses by the end of this year, the aim of the Catalan capital is to operate the cleanest bus fleet in Europe. The fleet of MPK S.A., the municipal public transport company of Krakow, is also expanding its hybrid fleet with 12 new buses by the end of 2016.

Allison Transmission began production of the H 40/50 EP system in 2003. Today, more than 7,800 city buses equipped with the Allison's hybrid system are operating in more than 230 cities worldwide. These vehicles have already saved an estimated 155 million liters of fuel and avoided more than 400,000 tons of carbon dioxide emissions.

As the hybrid bus fleet for Hannover, üstra is also renowned for providing service for the IAA Commercial Vehicles fair. Attendees wanting to experience an Allison-equipped hybrid bus can take either line 123 or 124, which are connected to the fair shuttle lines.
