Mack delivers hybrid vehicle to City of New York

During an event yesterday, the Volvo Group’s Mack Trucks subsidiary was recognized for delivering the first parallel-hybrid truck in the U.S. designed specifically for heavy-duty applications. The vehicle is a refuse collection truck that will be tested by the City of New York’s Department of Sanitation. As a result of the hybrid operation, in which an electric motor and a diesel engine work in parallel, fuel consumption can be reduced by up to 30% and carbon emissions decreased to the same extent. The vehicle also fulfils the stringent EPA10 emissions standards that become effective in 2010, which reduce hazardous emissions to near-zero.
“We are very proud to be the first city in the country with a Mack truck of this type,” said New York Mayor Michael Bloomberg. “We all want clean neighborhoods, clean air, a clean environment. And clean trucks like this are essential in delivering on that promise.” 

The Mack diesel-electric hybrid powertrain used in the truck features an integrated starter, alternator and electric motor. The system captures energy from braking, converts the energy to electricity, stores the electricity in batteries, and uses it to power the electric motor, which assists the diesel engine with propulsion of the truck. This technology provides the maximum fuel savings and environmental benefits on routes with frequent braking and accelerations, making refuse collection an ideal application.  

To date, the Volvo Group has developed some 20 vehicles including refuse collection vehicles, buses and wheel loaders, which use the Group’s parallel-hybrid solution. The base technology is standardized but adaptable and can thus be used in many different commercial vehicles, which reduces production costs when manufacturing in large volumes.

Mack Trucks has been a member of the Volvo Group since 2001. Visit for more information regarding Mack’s hybrid vehicles.
