WOOD DALE, Ill., June 24, 2013 (GLOBE NEWSWIRE) -- Cleantech engine supplier Power Solutions International, Inc. (PSI) (OTCBB:PSIX) and online grocery-delivery service Peapod, LLC will showcase a clean-fuel pilot vehicle starting today at the 2013 Alternative Clean Transportation (ACT) Expo, the largest gathering of clean-vehicle stakeholders in the US.

The 6.0-liter-powered delivery truck on display at ACT is the latest addition to a pilot program that PSI began with Peapod in late 2012. In the first phase, PSI outfitted four Peapod delivery trucks with 4.8-liter engines, two that ran on propane and two that ran on natural gas.

"With more than 23 million grocery orders delivered across 24 U.S. markets, we are committed to making our fleet as eco-friendly as possible. This pilot is the first step in a process to find the most environmentally impactful solution," said Andrew Parkinson, Peapod president and general manager.

In the pilot program, PSI delivered fully integrated, drop-in powertrain solutions customized to Peapod's trucks, with transmission, fuel tanks, and recommended fueling strategy. The 4.8-liter propane-powered engines featured special components including enhanced heads and valve-seat inserts, new engine-control systems and fuel systems.

The pilot trucks were driven in a suburban Chicago service area with a 160-mile radius. To date, the pilot has yielded cost per mile results of $0.32 per mile for propane, versus a cost of $0.52 per mile for unleaded gasoline—a savings of more than 38%. Driver feedback has been very positive, with no service issues reported and only minimal maintenance. Based on the pilot's success, Peapod is now working on a project to speed up fueling access.

"We are pleased with the results so far of this pilot program with Peapod," said Eric Cohen, PSI's Chief Operating Officer. "The goal of the Peapod pilot is to establish the financial and operational viability of using clean on-highway power systems for its delivery fleet, in order to reduce emissions and fuel costs.

The program is demonstrating that PSI's clean-fuel technologies can enable Peapod to reduce its fleets' fuel use and resulting emissions without compromising on engine power or performance. We look forward to potentially rolling out our customized engines to their fleet more broadly."

PSI will present its new products at booth number 331 at the ACT Expo at the Walter E. Washington Convention Center in Washington DC on June 24—27.
