Mack Trucks has introduced the new Granite series of construction and vocational trucks and the Freedom series of medium-duty, cabover trucks.

The Granite Series – built on Mack’s RD frame – boasts new styling, light tare weight (as low as 13, 900 pounds with the Cummins ISL engine option), ease of body installation, a roomier cab and a host of driver comfort and features, including air-ride cab, tilt/telescoping steering wheel, enlarged glass area and three interior trim packages.

With a wheelbase of 210 inches, the Granite is available with Mack’s E-Tech engine, with ratings from 300-460 hp, or Cummins’ ISL, with ratings from 310-330 hp. A new line of Mack Maxitorque ES transmissions, with a host of gear ratios and PTO options, is standard.

In addition, a 248-inch-wheelbase Granite Bridge Formula version is available for operation in areas of North America with strict bridge-formula weight regulations.

The new Freedom series consists of the Class 6 M and L, and the Class 7 XL and XXL models, each available in standard, 63-inch-BBC, and Xtra cab, 79-inch-BBC configurations. Wheelbases are 152 inches for the M, and 155 inches for the L, XL and XXL versions, and all models feature a 50 degree wheel cut “to ensure the tightest turning circles for any application, regardless of body type,” says Mack.

Standard power for all Freedom trucks is Mack’s 210-hp E3 engine, while a 250-hp rating is optional. An Eaton 6-speed, synchronized transmission is standard, and an Allison automatic is optional. Four-wheel disc brakes, combined with gas shocks and stabilizer bars on the front and rear axles, are also standard.

According to Mack, the Freedom series should be a pleasant place for medium-duty operators to do their work, with its passenger-car-like, “well-insulated environment and numerous new features to promote driver productivity and comfort.”
