Hybrid rubbish trucks and buses launched in Europe
Being woken up early in the morning by the sound of a rubbish collection truck rumbling along the road is a familiar irritation of modern life.
The rubbish truck uses an electric engine at low speeds and when stationary, and the diesel engine kicks in when the speedometer reaches 20 kilometres an hour (about 12 miles per hour).
Stefan Lindberg, driver of the truck, said: "All the people know that big trucks are very noisy. Now we come down the streets and you can't hear the truck - you just see it."
It is one of a number of large vehicles, including buses and construction equipment, on which Volvo is installing what it calls its fourth-generation hybrid technology, where an electric motor and diesel engine work in parallel and are used where they are most effective.
Volvo said this has increased the engine capacity compared with other hybrids, while reducing fuel consumption and improving driving characteristics.
"In a few years' time, hybrid technology will no longer be a special solution but a technology found in most new city buses and distribution trucks," Lief Johansson, president and CEO of Volvo Group said.
"The fourth generation hybrid technology has the potential to make such a development possible."
The company believes the technology will be commercially viable because it uses a large number of standard components that can be used across a range of different vehicles, and is adaptable, reducing production costs and times.
"Volvo believes that the prospects are favourable for developing hybrid technology for all heavy vehicle segments - everything from buses and construction equipment to trucks for distribution and long-haul traffic," Mr Johansson added.
As well as the ongoing refuse truck pilot, Volvo Buses has also launched its new hybrid bus, the Volvo 7700 Hybrid, in Europe.
Production of the bus, which can provide fuel savings of up to 30%, is scheduled to start next year, and field trials will be carried out in London.
