Volvo Receives Order for Twelve 7700 Hybrid Buses in Norway

The operator company Nettbuss has ordered 12 hybrid buses from Volvo Buses for service in Norway, thereby becoming the first company in the Nordic region to implement the hybrid technology commercially. The hybrid buses reduce fuel consumption by as much as 30%.

Nettbuss has ordered ten Volvo 7700 Hybrid buses for use in Trondheim and two Volvo 7700 Hybrid buses for use in Arendal in southern Norway. Nettbuss has studied Volvo Buses’ field tests of hybrid buses in Göteborg and London, and has itself tested the hybrid buses in various cities across Norway.

The 7700 Hybrid features a parallel hybrid system with the Volvo MD5 diesel engine and Integrated Starter Alternator Motor (I-SAM). The 4-cylinder, 4-stroke turbocharged and intercooled in-line diesel engine delivers 158 kW (212 hp) of power at 2,200 rpm and 800 Nm (590 lb-ft) of torque at 1,200 to 1,700 rpm. Continuous output from the I-SAM motor is 70 kW (94 hp), with 120 kW (161 hp) peak; continuous torque is 400 Nm (295 lb-ft), with 800 Nm peak. A 600V, 4.8 kWh Li-ion battery pack is roof-mounted and water-cooled. (Earlier post.)

During the spring, Volvo will deliver hybrid buses to customers in such countries as Switzerland, Austria, Germany and Denmark. Serial production will commence in April 2010, and deliveries of the 12 hybrid buses to Nettbuss in Norway will be made in July.

The roof mounted battery pack could be well suited to future charging at bus stops using an overhead charging system. Also you can dual fuel the engine on natural gas if required.
