Prime Minister Wulff fires the starting gun for the first NEOPLAN city buses with the MAN D20 EEV engine

(PresseBox) (Salzgitter, ) MAN Truck & Bus Deutschland GmbH is delivering the first NEOPLAN Centroliner city buses with production series MAN D 20 common rail engines and MAN’s own, additive-free MAN PURE DIESEL technology to Stadtwerke Osnabrück, the company that looks after Osnabrück’s public services and utilities. At the celebrations in the Osnabrück City Hall marking the handover of the first ten solo buses, at which the Lord Mayor, Boris Pistorius, and Dr. Stephan Rolfes, Board Member of Stadtwerke Osnabrück AG for Transport, were present, Peter Erichreineke, the Board Member of MAN Nutzfahrzeuge AG for Sales and Marketing, highlighted the special significance of these vehicles: "I am very pleased to be able to hand over these particularly attractive NEOPLAN low floor buses, which fulfil the most demanding emissions requirements in Europe at the present time. With our uncomplicated and particularly clean MAN PURE DIESEL technology we see ourselves at the absolute leading edge of developments in the commercial vehicle market."

Christian Wulff, the Prime Minister of Lower Saxony, also stressed the ecofriendliness of the vehicles and the necessity for their introduction in social terms. "We are proud that the first clean diesel buses to meet the EEV standard are now to be seen on the streets of Lower Saxony, and so are contributing significantly to the protection of the environment and to a better quality of life for its citizens." At the same time he congratulated Stadtwerke Osnabrück AG for its investment in the future. Stadtwerke Osnabrück introduced soot particle filters a number of years ago to keep particulate emissions as low as possible, and since 2005 they have been customers of the long-established NEOPLAN name for buses. With the delivery of a further 10 solo buses at the end of the year and one articulated bus, 18.75 metres in length, almost one third of the company’s fleet of some 100 buses will be NEOPLAN vehicles of the Centroliner low floor type.

On the basis of its MAN PURE DIESEL technology, MAN is clearly committed to exhaust gas recirculation technology (AGR) for the future. So far around 2000 vehicles have been delivered with this exhaust gas cleaning technology to Euro 4 standard and better. In Eastern European and overseas markets in particular there is a strong demand for the additive-free Euro 4 solution from MAN. With the delivery to Osnabrück after exhaustive field testing the new, horizontally-aligned MAN D20 common rail engine of 10.5 litres capacity is being introduced with power outputs from 280 to 360 hp. This engine is installed in more than 90 per cent of all MAN and NEOPLAN low floor buses and is therefore an important cornerstone of the sales strategy.

In contrast to the Euro 4 engines these innovative engines are fitted with the electronically controlled CRTec ® particle filter, which filters up to 99 per cent of particles out of the exhaust gas and is particularly effectively monitored. In addition the engine includes other internal features such as, for example, a two-stage exhaust gas turbocharger with intermediate cooling to achieve the required NOx values of the Euro 5 or EEV standards. Furthermore in the context of OBD 1B these values are exactly controlled as standard. MAN and NEOPLAN were the first bus manufacturers to be able to fulfil the EEV standard without the use of additives.

Extensive field tests have been completed for both the Euro 4 technology and also the EEV engines. In addition to the low maintenance requirements and the durability of the components that are relevant to emissions, such as the AGR, the two-stage turbocharger, and the MAN PM-KAT® or the CRTec ® particle filter these tests proved the high operating efficiencies of the new, reduced capacity engines in the D20 common rail series and also the D08 units tested. On average the consumptions of the new engines lie at least two per cent below those of the comparable Euro 3 engines from MAN. The fuel consumption is not impaired by the design features introduced to achieve the EEV standard; the behaviour of the new engines is neutral relative to that of the Euro 4 units.

In addition to the almost complete absence of particles, according to all available studies the bus also scores on the subject of CO2 emissions. With an average payload of 30 persons the NEOPLAN Centroliner, here in its 12 m variant, emits only some 35 g of CO2 per passenger-kilometre; with a full payload values of less than 10 g of CO2 per passenger-kilometre can be achieved, depending on model and variant. With the new MAN Hybridbus, a related type that will go into production in 2010, as much as 25 per cent of diesel consumption can be saved. With an annual distance travelled of around 60,000 kilometres this represents an annual CO2 reduction of up to 10 tons! The four (by the end of 2008, 14) MAN city buses with hydrogen-powered engines already engaged in fleet testing in Berlin, which are undergoing rigorous everyday operation up to 2009 as part of the EU-funded project HyFLEET:CUTE, are today already completely CO2-free and undercut all other emissions values by approximately a factor of ten.

The NEOPLAN Centroliner can look back on a history that is rich in tradition. The company was in fact the inventor of the low floor concept, a feature that today in Central Europe one cannot imagine living without. This success story began more than 30 years ago in Stuttgart-Möhringen with the N 814 model. Not later than 1987 this design concept became accepted in Germany and formed the basis of a family of models featuring everything that the customer wanted, including a double-decker variant. This tradition continues in the new Centroliner DD, announced at the start of 2007, of which 170 units will be delivered to Dubai from 2008 onwards as part of a total package of 400 NEOPLAN buses .

In addition to its extremely attractive design for a city bus, with standard dimensions of 12 x 2.5 x 2.87 metres, the Centroliner offers an attractive interior that is configured in a passenger-friendly manner in accordance with the latest ergonomic knowledge and legal requirements, with 37 seats and 53 standing places and a J-seat arrangement at the rear inhibiting vandalism. An air-conditioning system and a folding ramp on the second door are features that are now viewed as standard, as is the option of lowering the vehicle by 80 mm at bus stops, or the electronic ABS and ASR systems. The new EEV unit produces 280 hp with a maximum torque of 1,250 Nm and so is very well equipped for all terrains.


NEOPLAN is the leading brand name for buses in the MAN Commercial Vehicles Group. The company, with its headquarters in Pilsting in Lower Bavaria, develops, produces and markets leading models of buses in the coach, overland, public transport and specialised sectors in conjunction with sites in Germany, Poland and Turkey. NEOPLAN can look back on a tradition that extends over more than 70 years, in which more than 30,000 vehicles have been delivered to more than 175 countries. At all times these have been, and continue to be, leaders in innovation and design.
