Commercial trucks powered by BAE Systems’ HybriDrive parallel hybrid electric propulsion system use 30 percent less fuel than those using traditional diesel engines, according to tests carried out by the company.
The fuel economy was evident on a range of driving cycles, but the system performed best on stop-and-go cycles where average speed is between five and 20 miles per hour. This would make the engine a good choice for refuse collection and delivery trucks, BAE Systems said.
A truck fleet owner who uses the HybriDrive parallel system can expect payback within three to five years, according to the company.
In April, BAE Systems announced plans to set targets for waste as well as energy and water usage, starting this year.
According to the company’s integrated 2010 corporate responsibility and annual report, business conduct and safety were BAE’s two key corporate responsibility priorities in 2010. But the company said it would be increasing its focus on environmental performance, which could “impact the long-term sustainability of the group.”
