Big Mack

“One look at this truck,” says Tom Kelly, Mack vice president of marketing, “and you know it was engineered to handle the meanest jobs – logging, oil fields, heavy equipment or severe heavy haul.”

Mack Trucks has debuted what it describes as the most powerful truck in the company’s 108-year history.

The Titan, designed for heavy transport and heavy construction, is powered by the new 16-liter Mack MP10 engine, with a top rating of 605 hp and 2,060 lb.-ft. of torque.

An earlier version of the Titan from Mack Trucks Australia has been hauling road trains through the Outback since 1995. Mack says the U.S. Titan has the most powerful engine ever offered by the company, as well as advanced engineering for excellent visibility, productivity and driver comfort. Deliveries will begin in late 2008.

The Titan has high ground clearance and a long hood, while the cab is moved back and up on the chassis for the classic “heavy haul” position and added driver visibility. The higher cab also improves airflow for underhood cooling.

The most noticeable exterior features are the twin cowl-mounted Growler air intakes, designed to minimize moisture, screen debris and allow easier service, as the air filters are located under the cab.

The Titan’s large grille surround is 4 inches of chromed cast aluminum, complemented by similar headlight bezels. The headlights have an impact-resistant Lexan lens and easy-to-replace lamps.

Eye-catching features include chrome horns, a chrome “eyebrow” on the hood fender wells, a stainless-steel sun visor available in 10- and 13-in. widths (in the Rawhide Edition), stainless-steel skirt lighting with optional personalization, large 6-in. dual exhaust stacks that are outboard mounted behind the cab and a bright-finish metal bumper with integrated driving lights.

The Titan’s Cornerstone chassis, refined on the Mack Granite vocational truck, is offered in three frame rail thicknesses – 8 mm, 9.5 mm and 11 mm – with optional full or partial 5 mm inside channel reinforcements and application-specific crossmembers. Frames are rated at 120,000 psi.

The cab is mounted on twin wide-spaced air bags with shocks to help neutralize the harsh bumps found in the vocational world, while stabilizers prevent cab sway. An air assist clutch pedal is positioned low to save drivers some leg effort. A small sleeper will be available on the Titan next year.
