Hybrid trucker

The town of Framingham put this truck into service about a year ago for inspecting sewer lines for preventive maintenance. The fuel savings were dramatic: the previous diesel truck got about 4 or 5 miles per gallon, whereas this one gets about 11 miles per gallon in stop-and-go driving and over 15 miles per gallon on the highway. The battery can be charged overnight from a wall charger or charged by the diesel engine during operation.
