Allison Transmission announced that Mack Trucks, has selected the Allison 4500 Rugged Duty Series (RDS) as the exclusive transmission currently offered for its new compressed natural gas (CNG)-powered Mack Granite model. This partnership is the latest example of Allison’s ability to deliver optimized performance and capability in demanding vocations, agnostic of fuel source for the powertrain.
The 4500 RDS fully automatic transmission has been offered in the Mack Granite diesel model for over 20 years. When Mack set out to develop a vehicle for refuse collection customers seeking an alternative fuel solution, they were able to seamlessly pair the proven 4500 RDS transmission with a 320-horsepower Cummins L9N engine. The CNG-powered Mack Granite truck will enable customers to reduce emissions to meet upcoming changes to regulatory standards.
“The CNG Granite model is a perfect example of Mack’s ability to produce customized trucks that meet the needs of our customers,” said Jonathan Randall, president, Mack Trucks North America. “Our refuse customers asked for a CNG-powered Granite, and through our partnerships with Allison and Cummins, we delivered a solution that offers the durability, reliability and driver comfort that Mack is known for, with the added benefit of reduced emissions and noise levels.”
Allison said its collaboration with Mack on the CNG model is a testament to the company’s commitment to offering a portfolio of conventional, electric hybrid and fully electric propulsion solutions designed to meet the needs of customers as they strive to reduce emissions.
“Allison transmissions, when paired with natural gas engines, have the ability to deliver up to 90% noise reduction compared to a diesel-powered vehicle,” said Rohan Barua, vice president, North America Sales, Global Channel and Aftermarket, Allison Transmission. “The CNG-powered Mack Granite will enable customers to optimize the productivity of their fleets, improve fuel economy, and reduce noise and emissions. We are pleased to partner with Mack on this sustainability initiative.”
