New York City is the first customer to experience a Mack diesel-electric hybrid model.
The Mack TerraPro Low Entry truck meets EPA 2010 emission standards, the first of its kind intended for production, the company says.

"We are very proud to be the first city in the country with a Mack truck of this type. We all want clean neighborhoods, clean air, a clean environment. And clean trucks like this are essential in delivering on that promise," said Mayor Michael Bloomberg.

The model is equipped with a rear loading refuse packer body, a 325-horsepower Mack MP7 engine and Selective Catalytic Reduction exhaust aftertreatment technology. The Mack hybrid electric powertrain used in the truck features an integrated starter, alternator and motor that assists the MP7 in providing torque to the wheels and regenerates energy during braking. The energy captured during braking (stored as electricity in lithium ion batteries) is then used in place of diesel fuel and helps launch the truck from stops.

This technology provides the maximum fuel savings on routes with frequent braking and accelerations. The use of this hybrid system is expected to improve fuel economy by 20 percent to 30 percent and provide a similar benefit on greenhouse emissions, while reducing cost of maintenance.

"The delivery of this truck marks a key milestone in a long-standing, successful partnership," said Dennis Slagle, Mack president and CEO. "The Mack-New York City connection goes back more than 100 years. The Mack brothers built their first buses and trucks in Brooklyn."
