The new generation of the MAN Lion’s City introduces a completely new design of city bus to the urban environment, based on its tried and tested predecessors from MAN. During the development of the completely redesigned driver’s workplace, we worked hand-in-hand with our customers.
In order to deliver future-proof vehicles in MAN quality, we take our time during development.
1million test cycles
The new MAN Lion’s City comes with a new door system, specially developed by MAN. Various tests, including temperature level tests and corrosion tests of individual components and road tests in Spain, Sweden and Austria, provided helpful insights to support the development process.
Improved efficiency and environmental protection in scheduled bus services: with the smart energy management of the MAN EfficientHybrid optional equipment, your MAN Lion’s City brings in triple savings – on fuel, exhaust emissions, and noise emissions.
With MAN EfficientHybrid, your MAN Lion’s city benefits from smart energy management. The main component is a robust and wear-free electric motor which is installed in the driveline between the engine and the gearbox and serves as a crankshaft starter alternator. Thanks to this alternator, combined with a roof-mounted UltraCap energy accumulator and a smart control system, your vehicle’s energy efficiency increases substantially. By the way: MAN city buses with EfficientHybrid are officially registered as hybrid buses.
Brake energy recuperation
Each braking process is a win for your Man Lion’s City with EfficientHybrid. This is effected by the crankshaft starter alternator, which immediately converts the generated recuperation energy into electrical energy.
Stops with zero exhaust emissions and noise emissions
The stop-start function switches off the diesel engine of your MAN Lion's City at each station and red light, giving your passengers a first-hand experience of the hybrid technology. Fuel consumption and the corresponding exhaust emissions and noise emissions drop to zero. The smart energy management system uses the free energy stored in the UltraCap module to supply the vehicle electrical system.
Fuel- and emission-optimised driving
Since the stored electricity is also used whilst driving, the diesel engine has to produce less energy. This means even less fuel consumption and exhaust emissions.
Durable and maintenance free system
Our MAN EfficientHybrid energy technology is durable and designed to be maintenance free: the crankshaft starter alternator works without current collector brushes and mechanical intervention. The UltraCap energy accumulator has an extremely long service life. It can manage up to 2.6 million stop-start cycles for your Man Lion’s City with EfficientHybrid with ease.
When the vehicle slows down before coming to a halt at a red light or the next station, the crankshaft starter alternator converts the generated brake energy into electrical energy (1). The electricity gathered in this process is then safely stored in the high-performance capacitors of the UltraCap module.
While the vehicle is at standstill, the MAN EfficientHybrid system turns off the combustion engine (2). At the same time, the UltraCap accumulator takes over the supply of the vehicle electrical system. All functions, such as opening and closing of the doors, operation of the interior lighting and the ventilation are now supplied with power by the accumulator.
Once driving off again, the crankshaft starter alternator uses the available energy from the UltraCap capacitors to start the combustion engine.
If sufficient energy is available in the UltraCap module, the EfficientHybrid system also supplies the vehicle electrical system with power while driving (3). In addition, the crankshaft starter alternator can use excess stored energy to act as an additional hybrid drive and thereby take some of the load off the combustion engine.
