PSI and Peapod Showcase Propane Autogas Fleet Vehicle

June 26, 2013

Cleantech engine supplier Power Solutions International, Inc. and online grocery-delivery service Peapod, LLC will showcase a clean-fuel pilot vehicle Wednesday, June 26 at the 2013 Alternative Clean Transportation (ACT) Expo, the largest gathering of clean-vehicle stakeholders in the US.

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

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 4.8L 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 32 cents per mile for propane, versus a cost of 52 cents per mile for unleaded gasoline, a savings of more than 38 percent. Driver feedback has been positive, with no service issues reported and minimal maintenance. Based on the pilot's success, Peapod is now working on a project to speed up fueling access.

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.
