Mack Truck

Part of the Series: Raw to Ready

The highway truck -- a modern workhorse, a heavy hauler vital to commerce -- carries an 80,000-pound payload and must operate in every condition from sub-zero cold to triple-digit heat. To survive, it must be strong, durable and fuel-efficient, like the Mack Pinnacle, an engineering achievement made possible by platinum, petroleum, copper, manganese and polyurethane.
