The BS-IV compliant Volvo hybrid city bus helps to clean the city’s lungs. Readily deployable where diesel buses already run, the hybrid bus delivers up to 30-35 percent reduction in emissions and also a similar improvement in fuel economy. This is because the bus can be driven on electric power when moving off from standstill and for accelerating to speeds of up to about 20 km/h. All along operators and passengers enjoy the same levels of manoeuvrability, higher average speeds, lower NVH, longer service life, enhanced comfort & safety that they have come to expect from the premium 8400 City Bus platform.

High comfort for drivers and passengers

High comfort for drivers and passengers

Large glass windows, electronically controlled suspension, comfortable seats and excellent body build quality makes for a smooth and comfortable journey. The driver’s environment is ergonomically designed and has a fully adjustable steering position and a separate ventilation system that can be equipped with air-conditioning.

Function and safety

Function and safety

The Volvo hybrid city bus has low entry, a wide centre aisle and wide doors. This permits swift and convenient passenger movement on board and therefore shorter standstills at bus stops. Electronic Braking Systems, door brakes and Anti-lock braking systems deliver the high levels of safety expected from a 8400 City Bus.

Features

Powerful and stable chassis

Powerful and stable chassis

The frame is robustly dimensioned and is made of high-strength steel. The suspension system features sturdy air bellows that offer high comfort and allow the bus to kneel for more convenient boarding. The front axle is of the conventional type, offering good comfort but at the same time better anti-roll stability and an excellent turning circle.

Intelligent driveline

Intelligent driveline

The driveline consists of a diesel engine, clutch, transmission and I-SAM (Integrated Starter Alternator Motor). The brain of the system is an electronic control module known as the PMU (Powertrain Management Unit). It regulates engagement and disengagement of electric and diesel power as needed, as well as gearchanging modes and battery recharging.

Compact drive unit

The electric motor’s high power output allows a smaller and more economical diesel engine to be fitted. In Volvo’s hybrid bus, a 4-cylinder 5-litre Volvo diesel engine producing 215 hp is deployed.

Auxiliary functions powered by electric motors

Auxiliary functions powered by electric motors

The auxiliary functions do not need to be powered by the diesel engine, so there is greater freedom in choosing their location in the vehicle. The power steering pump, air compressor and cooling fan are all powered by separate electric motors. Each electric motor operates only when it is really needed, in order to save energy.

Regenerative Braking

Regenerative Braking

The electric motor serves both as a propulsion motor and a generator. When the brakes are applied their retardation effect is harnessed to recharge the batteries – energy that would otherwise be simply wasted in the form of surplus heat in the braking system. Repeated braking is thus an operational benefit.
