Chevy Volt Emits Significantly Less Smog-Forming Pollution than Other PHEVs

The Chevy Volt emits significantly less smog-forming pollution than other PHEVs, according to a GM study presented to the Society of Automotive Engineers. Furthermore, GM-Volt reports that the engineering analysis for the new 2016 Volt that will be on the market soon shows Chevrolet’s new Volt will outperform the 2011–2014 specification Volts studied.

GM-Volt explains the study and reasons the improvement is the Volt has a battery 2 to 4 times larger — rated at least double the all-electric range of any conventional plug-in hybrid.  Thus, in this remarkable system architecture, even with a higher top battery-electric speed, the engine stays off longer.  The Volt’s routine trips every day are thus cleaner.

The paper, Chevrolet Volt Electric Utilization, by A. Duhon, K. Sevel, S. Tarnowsky, and P. Savagian, reports that the Volt can offer 40 times or more all-electric trips compared to “competitors.”  With such distinction, the Volt stands out far in front compared to PHEVs by Toyota, Honda, and Ford — which have batteries ½ to ¼ the Volt’s size.
