World premiere of Mercedes-Benz CapaCity L, the longest Mercedes-Benz bus

It is an imposing 21 m long and provides space for up to 191 passengers as standard. It consumes well below 0.5 l/100 km per passenger and has only minimal emissions: The CapaCity L high-capacity articulated bus makes an important contribution towards counteracting
the transport problems in inner cities.

The new CapaCity L is anything but on the usual scale - at 21 m in length, it is around three metres longer than conventional articulated buses. It is therefore the answer to current transport problems, since frequently used bus lines are reaching their limits as passenger numbers continue to rise. With the CapaCity L, transport operators can carry far more passengers with the same number of buses.

Whether new shopping centres, residential areas or industrial estates, they can all be served quickly and cost-effectively with the CapaCity L without the need for high investment - all the high-capacity bus needs is a road. The CapaCity L is therefore ideally suitable for BRT (Bus Rapid Transit) systems.

"The CapaCity L makes an important contribution towards reducing the volume of traffic in inner cities. It is the longest European bus with just one articulated turntable. Plus it is environmentally friendly - no other bus with a diesel engine has lowerCO₂ emissions per passenger," said Hartmut Schick, Head of Daimler Buses.

Ulrike Riedel, Member of the Executive Board responsible for Human Resources and Operations at Hochbahn, added, "We are pleased about increasing passenger numbers. At peak times, we cannot further increase the frequency at which our buses are running in many cases, so high-capacity buses such as the new CapaCity L are a very appealing option for us."

Hamburger Hochbahn will this year become the first transport operator to trial the new Mercedes-Benz CapaCity L under real operating conditions. For this purpose, the high-capacity bus is being used on Metrobus Line 5, from the city centre to the university quarter in the north west of the city. It is Western Europe's busiest bus line.

Not only is the CapaCity L large, it is also clean. Its engine, a six-cylinder in-line unit with a displacement of 10.7 l compliant with the Euro VI emissions standard, has an output of 265 kW (360 hp) or 290 kW (394 hp). Optimum consumption is not only the name of the game for the engine and the automatic transmission adapted for the CapaCity L, but also for all the ancillary components.

Consequently, when the CapaCity L is operated on a usual regular-service route with a full complement of passengers on board, it consumes well below 0.5 l/100 km per passenger. This figure makes it the most economical urban bus with diesel drive and is well below that of a passenger car. The fuel consumption equates to CO₂ emissions below 13.3 g/km per passenger - a sensationally low figure.

Another ingenious feature is the unique ATC (Articulated Turntable Controller) system on the CapaCity L, newly developed by Mercedes-Benz. ATC controls the hydraulic damping of the articulated turntable quickly and on demand, ensuring optimum steering characteristics during normal operation. If any instability is encountered - on a slippery road surface, for example - ATC stabilises the articulated bus within the bounds of physical possibility. The ATC is thus the only system of its type to achieve anything like the effect of an electronic stability control system (ESP). This means a new level of safety for articulated buses.
