Cummins and PERC have developed a 6.7L medium-duty propane demonstration engine that exceeds diesel in performance (torque and power output) and emissions reductions and matches diesel in thermal efficiency while significantly lowering carbon emissions. The technology is currently being field tested by AmeriGas.

He is responsible for growing propane autogas market share in on highway light-, medium- and heavy duty vehicle markets. Before joining PERC in January of 2020, Whaley ran his own clean transportation consulting company. Whaley was formerly a director of business development for Roush CleanTech and performed Autogas research and business development for Blossman Propane.
