Mack

      There are none now, but there might be one later on. The long-nose CL could have been a large car if it had a big sleeper, but they were built only as daycabs with a heavy frame to replace the old RD-800. The CL has been powered only by Cummins' ISX for the past few years, and now it's out of production. A replacement is due in January '08 – again as a heavy tractor and truck and using the upcoming 16-liter MP10 (based on Volvo's D16). Planners are considering offering sleepers to tap into the large car market.
      Other HD Models: The new Pinnacle becomes the principal highway tractor, in replacing the vision and CH. The stylish rawhide continues as the owner-operator choice. Pinnacle has a roomier cab and fancier interior, and a choice of several sleepers. As on most current models, the sleeper boxes can be removed and a wall kit installed at the cab's rear, turning the tractor into a daycab for local and regional service. The granite vocational truck and tractor get a 4-inch-longer cab with new interior features. The MR and LE low-cab-forward vocational trucks work mostly as trash haulers and concrete pumper carriers.
      EPA '07 Diesels: Only new Mack Power diesels, designed by Volvo Powertrain and built in Hagerstown, Md., will be used starting this month. Mack is dropping the Cummins ISX and ISL that sold in only small numbers. Already used in certain Granites is the 11-liter MP7, with ratings of 325 to 405 horsepower, which will have been aftertreated. Later in '07, a 13-liter MP8, with 425 to 485 horsepower, will debut. The MP engines will come in Maxidyne, MaxiCruise and Econodyne versions, and be available with a PowerLeash engine brake. Mack says its MPs use less fuel than the old ASET engines.
