GOTHENBURG, Sweden — Volvo Group says it’s now rolling out its “fourth generation” hybrid technology.

“Our hybrid solution for heavy vehicles is completely different from anything that has existed in the market to date,” said Leif Johansson, president and CEOof Volvo Group. “As a result of our volumes and resources, we have succeeded in developing a more standardized platform solution, which is a prerequisite for the hybrid technology’s ability to have a widespread commercial impact in the market for heavy vehicles.”

Volvo’s hybrid technology is built upon the I-SAM (Integrated Starter, Alternator Motor) concept, which includes an electric motor that works in parallel with the conventional diesel engine.

“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,” Johansson predicted. “The fourth-generation hybrid technology has the potential to make such a development possible.”

The most recent development includes the use of standard components, rather than costly specialized parts which have hindered high-volume manufacturing. Johansson said Volvo Group is confident its hybrid technology will be viable in long-haul applications, as well as regional delivery.
