Lightning Hybrids, a maker of hydraulic hybrid systems for medium- and heavy-duty trucks and buses (earlier post), released initial results from emissions testing conducted by an independent testing facility in Colorado of two medium-duty trucks upfitted with the Lighting Hybrids system. The results show decreases in NOx of up to 90% and decreases in CO2 emissions of up to 16% over the same baseline vehicle, depending upon the drive cycle tested.

Lightning Hybrids tested two vehicles: a 2013 Ford E450 6.8-liter V10 and a 2010 GMC 3500 Savana Cutaway 6.0-liter V8. Both vehicles were first tested without Lightning’s hydraulic hybrid system to provide a baseline with which to compare the results with the hybrid system installed.
