It's the city that never sleeps. It's by far the largest city in the United States, more than double the population of Los Angeles. It's New York, and one of the most progressive cities when it comes to cleaning the air.

With a goal to curb carbon dioxide by 30 percent by the year 2017, all areas of city government are striving to reduce its carbon footprint. For the New York City Parks Department, it's a commitment it welcomes whole-heartedly.

"Sixty-four percent of our fleet of vehicles is already running on some sort of alternative fuel," said Keith Kerman, assistant commissioner for the parks department. "Some are even all electric, a few vehicles are solar powered, and many are CNG and hybrid powered. By the end of 2010, we're projected to be up to 72 percent."

The 2010 goal is being reached, in part, by the recent addition of Kenworth T370 diesel-electric hybrids. The City has been placing 17 Kenworth hybrids into service – eight with rack bodies and lift gates and the rest with 5-yard dump bodies. The trucks were purchased through Gabrielli Kenworth.

"The Kenworth T370 hybrids already in service are working great and preliminary results show we're reducing fuel consumption by up to 40 percent," said Kerman. "We'll have concrete results after a year, but we're very pleased with results to date. They're also great looking trucks – drivers love them, plus we are working on this in partnership with our sister agencies, especially Sanitation."

According to Kerman, New York City has the largest parks department in the country, encompassing 29,000 acres, divided up among 2,000 parks and more than 500 ball fields. The Kenworth T370 hybrid dump trucks are targeted to haul dirt, sand and clay to ball fields, as well as for general assignment work. The T370s with rack bodies are our do-all vehicle and can support a wide range of park activities – from pruning to general maintenance. The hybrids are especially attractive since there is so much stop-and-go activity with the vehicles."

The city's Kenworth T370 hybrids are specified with a PACCAR PX-6 engine rated at 240 hp and 660 lb-ft of torque. Kenworth hybrids feature the Eaton® diesel-electric hybrid power system, integral transmission-mounted motor/generator; and frame-mounted 340-volt, lithium-ion battery pack. Electricity generated through regenerative braking is stored and used for acceleration, assisting the diesel engine. Kenworth offers a high resolution, full color in-dash display to monitor the hybrid system. As the power requirements for different driving conditions change, the screen constantly updates the driver on system status, allowing the driver to optimize the performance of the hybrid system.

"We want our vehicles to be role models for what government can do," concluded Kerman. "We view being a green fleet and an environmental advocate as one of our missions for the New York City Parks Department."
