Sigma’s hybrid composite bus body boosts fuel efficiency

June 9, 2008

Sigma Industries Inc., a Quebec-based composite and metal products manufacturer, has developed a new green concept in body shell technology for urban transit buses, the Hybrid Composite Bus Body. Mainly targeted at the emerging hybrid electric drive market, for both city and over-the-road transit vehicles, the solution will be introduced at the American Public Transportation Association annual meeting in October.

Weighing in at nearly three tons less than a regular-sized transit vehicle body shell, the company says its corrosion-resistant composite material is 20-percent lighter than conventional metal bodies, which will enhance fuel efficiency. Furthermore, composite materials resistance to corrosion should extend vehicle life. Although mainly aimed at transit vehicles equipped with hybrid engines, Sigma’s body shell technology can also equip diesel engine-powered vehicles.

Reflecting another technological breakthrough, the body is constructed of longitudinal, structural modules that are bonded together that do not restrict body length by the size of the mould. In so doing, Sigma is able to customize the transit bus body to match the OEM’s market requirements for style, length and interior finishes. In addition, the environmentally friendly bodies are comprised of bio-resins that can be disassembled for end-of-life disposal.

“It’s not just about building a better product, it’s about integrating customer requirements and anticipating market trends, two key elements in Sigma Industries’ growth strategy,” said Denis Bertrand, Sigma president and CEO.

“We are excited by the vast market potential for our innovative technological solution, as all market participants will enjoy benefits. Our revolutionary body shell will enable transit agencies to maximize their return on investment while our flexible manufacturing process will greatly simplify final vehicle assembly by OEMs.”
