The LT Series Class 8 trucks incorporates operator features uncovered during the company’s DriverFirst product design focus. The cab focuses on elbow room, hip room, and leg room. The redesigned interior has a premium gauge cluster with a digital driver display that places everything within comfortable reach, while offering drivers real-time monitoring of fuel economy and other alerts.
Aerodynamic improvements not only boosted fuel efficiency, but also yielded a four-Sone decrease in wind noise. Other improvements include standard LED headlamps to improve night vision, a column-mounted gear-shifter that allows drivers to keep their eyes on the road, and a redesigned one-piece side window that affords the driver a clearer line of sight.
Navistar evaluated data collected from its remote diagnostics system, OnCommand Connection, and made multiple enhancements for increased reliability and serviceability.
- The new single-canister aftertreatment system is 60 percent smaller, 40 percent lighter, and simplified for quicker servicing.
- The new LED headlamps and fog lamps deliver brighter light and intensity, and have tough new polycarbonate headlight lenses that protect them against breakage.
- The cab wiring includes all-new harnessing and an in-cab power distribution module that is inside the truck, away from the elements.
- All key service points under the hood, inside the cab and around the vehicle are ergonomically designed for easy access and servicing, and many components have been engineered with longer intervals between required maintenance.
