Mack Trucks upgraded the interiors of its Mack Granite and Titan by Mack models.

The upgrades offer drivers a more comfortable and ergonomic work environment.

The interior enhancements include:

-An optional center storage console, located between the seats, providing nearly one cubic foot of convenient space for large-item storage. The console includes interior lighting and a 12-volt power supply;

-An optional bodybuilder console, mounted between the driver and passenger seats. The console works with Mack BodyLink III electrical interface and provides a 150 square-inch top plate that is easily removed for bodybuilder control and wiring installation and includes a dispatch box, trash bag hooks and netted storage;

-Optional ambient red floor lighting, subtle or indirect, for use at night when driving or when stationary;

-A standard "dead pedal" for the driver's left foot to maximize comfort while driving and to help the driver maintain an ergonomically correct seating position;

-Improved functionality for Mack PowerLeash+ Engine Brake controls, standard on all models, enabling the driver to set and maintain a target downhill braking engagement speed, in or out of cruise control; and

-Self-cancelling turn signals, which are standard on trucks and optional on tractors.
