Mack will officially launch its new range of EPA2010 compliant SCR trucks at the World of Concrete show in Las Vegas this February. The SCR unit forms part of a emissions control system that Mack is calling ClearTech. Mack has had ClearTech equipped vehicles with customer fleets for over two years now and is happy with the performance the vehicles have achieved. Coupled with Mack's MP Series engines, the system is fully compliant with the latest EPA emissions standards.
