Peterbilt delivered two hybrid Model 335 trucks to VinLux Fine Wine Transport last week for use in the San Francisco area. The medium-duty trucks have a 30%-50% increase in fuel economy and “dramatically reduce tailpipe emissions of hydrocarbon (HC), carbon monoxide (CO), and oxides of nitrogen (NOx),” according to a Peterbilt press release.

The trucks have an electric motor to assist the gasoline-powered engine and regenerative braking to capture energy for reuse on accelerating. Representatives of VinLux expect the savings in gas to make up for the premium hybrid price in the next few years of use, while at the same time getting them closer to their goal of reducing carbon emissions.
