ISE Diesel Hybrid-Electric Drive Systems to Power Optima Opus Buses for Town of Avon and Other Transits

SAN DIEGO, CA, June 26, 2007 — ISE Corporation recently received orders for its ThunderVolt diesel hybrid-electric drive systems for additional 30-foot Optima Opus buses. These are part of a contract awarded to Optima Bus LLC. in 2006 by the Town of Avon, Avon, CO. The original award included a base order of up to five hybrid Opus buses with an option of an additional 10 buses.

In addition to one hybrid Opus for the Town of Avon, an additional three were ordered by Lake Erie Transit Authority, Monroe, MI, and two more by Hampton Roads Transit, Hampton Roads, VA.

The ISE-powered hybrid Opus low-floor buses bring advanced technology to the under 30' Opus model, delivering powerful performance, fuel efficiency, reduced maintenance and increased ridership appeal all in one eye-catching package. Utilizing road-proven ISE-Siemens ThunderVolt hybrid technology built around Siemens ELFA motors, generators and inverters, the sleek-looking Opus ISE series hybrid uses a conventional diesel engine only to generate electricity.

A hybrid Opus is currently undergoing tests at the Altoona Bus Research and Testing Center.
