Mack and Volvo both announced that their model year 2014 trucks and tractors are now certified by the U.S. Environmental Protection Agency and National Highway Traffic Safety Administration as meeting 2014 fuel efficiency and greenhouse gas regulations.

These were the first-ever fuel efficiency and greenhouse gas regulations for heavy trucks.

Certification of Macks entire vehicle portfolio reflects our continued commitment to fuel efficiency, environmental stewardship, and the countrys long-term energy security, said John Walsh, Mack vice president of marketing.

"Volvo is committed to leadership in fuel efficiency, and to reducing the carbon footprint of our operations and products," said Goran Nyberg, president, Volvo Trucks North American Sales and Marketing. "Environmental care is a longstanding Volvo core value, and we will continue to work with EPA and NHTSA to deliver on the important goals of these regulations."

The EPA and NHTSA certifications apply to all configurations of Volvo VNL, VNM, VHD and Volvo Autohauler (VAH) models.

Macks complete lineup of model year 2014 truck and tractor models are fully compliant, including the Mack Pinnacle, Granite, TerraPro, and Titan.
