DURABILITY AND RELIABILITY
The Model 337 is constructed with an all-aluminum cab that is lightweight for fuel efficiency and corrosion-resistant for durability. The Metton® hood is lightweight but strong, and tilts open a full 90 degrees for easier access to key service points. The stainless steel grille surround is long lasting, and its durable design provides superior protection of the engine cooling system.
OPERATOR COMFORT AND PRODUCTIVITY
The Model 337’s technology starts literally on the leading edge with high-intensity forward lighting. As soon as drivers sit behind the wheel, it will be obvious that this is one advanced truck. The LED backlit gauges readily communicate systems status and are designed to reduce eye strain. The standard driver’s in-dash display includes virtual gauges and truck, trip and performance information in driver-selectable English, French or Spanish. The optional diesel electric hybrid controls provide real-time feedback to the driver, encouraging optimal driving style and maximizing efficiency.
