Volvo To Start Serial Production Of Hybrid Buses
Volvo Buses said that it will start serial production of its hybrid bus Volvo 7700 Hybrid and double-decker Volvo B5L Hybrid. The company said that hybrid bus will reduce fuel consumption by up to 35% and carbon emissions by an equal amount.
According to Volvo, the 12-meter Volvo 7700 Hybrid bus is being built in its plant in Wroclaw, Poland and chassis for double-decker Volvo B5L Hybrid will be built in Boras, Sweden. The coaches for double-deckers will be built by Wrightbus in Northern Ireland.
Volvo’s hybrid buses feature a small diesel engine and an electric engine that can operate it independently or jointly. When the brakes are applied, the brake energy is utilized and stored in a battery, which then drives the electric engine when bus accelerates again.
In addition, the engine switches off automatically at bus stops and then restarts only with the help of electric engine. The diesel engine does not start until the bus reaches 15-20km/hour.
Hakan Karlsson, president of Volvo Buses, said: “This is a major step for the Volvo Group and for the bus industry. There is now a hybrid bus in the market, which will significantly reduce fuel consumption, strongly reduce emissions and is also commercially viable.”
