Mack Trucks has introduced a natural gas-powered version of its TerraPro Cabover model for the collection of refuse and construction applications.

The announcement and display of the new vehicle occurred Oct. 28 at Mack’s World Series Conference in Allentown, Pa.

The Mack TerraPro Cabover model is available with heavy-duty natural gas engines supplied by Cummins Westport. The nine-liter Cummins Westport ISL G is rated at 320 horsepower, can use compressed natural gas (CNG) or liquid natural gas (LNG) and has a three-way catalyst to meet EPA 2010 emissions standards.

“With this new natural gas product, an industry-leading truck is now coupled with an alternative fuel option,” said Curtis Dorwart, Mack vocational products marketing manager. “The cabover design combines Mack durability with an interior aimed at driver comfort and productivity. Adding the natural-gas powered engine allows our customers to be environmental leaders in their markets and communities.”

The TerraPro Cabover’s low-profile electronic dash enhances visibility while incorporating comprehensive driver information displays. The instrument cluster features 25 indicator lights and an automatic transmission temperature gauge. Electronic gauges improve accuracy and reliability while eliminating oil lines and most air lines from the gauge cluster. An engine hour meter that features a wake-up display when the ignition is off is included as well. A battery backup protects vital information stored in the engine control systems.

The TerraPro Cabover model features the next generation of Mack’s Vehicle Management and Control System – V-MAC IV – allowing customers to better control costs and closely monitor truck and engine performance. V-MAC IV offers more than 100 proven programmable features and adds a host of new items, including road speed tamper detection, integrated starter protection and programmable daytime running light override. V-MAC IV electronics include DataMax, advanced software that captures information such as vehicle trip histories, duty cycle information and scheduled maintenance intervals.

“With the Mack TerraPro model series, we’ve created a family of trucks that meet the application and productivity needs of our customers – and now the demand for cleaner emissions and alternative fuel options as well,” Dorwart added. “The natural gas version of our TerraPro low-entry model is already being very well received in the market, and we’re confident our new natural gas-powered TerraPro Cabover model will be as well. Both reflect the Mack long-standing commitment to innovation.”

In addition, Republic Services, a provider of solid waste collection, transfer, recycling and disposal services has recently accepted delivery of 41 natural gas TerraPro Cabover versions.

Natural gas-powered vehicles are becoming more prevalent in the refuse collection industry. A growing number of companies as well as major metropolitan municipalities are mandating the installation of alternative fuel vehicles into contracts of potential refuse haulers. Additionally, the latest alternative fuel TerraPro Cabover qualifies for tax credits.
