28 commercial carrier journal | may 2017 International debuts regional-haul tractor BY JASON CANNON I nternational Truck's new RH Series tractor replaces the ProS- tar 113-inch BBC model and the TranStar 107. e regional-haul tractor, introduced last month at ExpoCam in Montreal, will be offered in a 56-inch low-roof sleeper, 56-inch high-rise sleeper, day cab with roof fairing and 56- inch high-rise sleeper with roof fairing. The RH Series is the first to get International's new 12.4-liter A26 engine and Bendix's Wingman Ad- vanced Collision Mitigation system as standard. Aerodynamic and driveline im- provements make the RH Series up to 6 percent more fuel-efficient than the trucks it replaces. e same aerodynam- ic improvements also reduce wind noise. Engineers with International's parent Navistar redesigned side windows and mirrors to provide enhanced side visibility. e truck has an inside wheel cut of up to 50 degrees, delivering a curb-to-curb turning radius of 27 feet and 10 inches. e interior design was based on a study of interaction points between the driver and the truck, Navistar says. Fea- tures such as a large swept-back wind- shield, optimized mirror placement and an aerodynamic sloped hood contribute to greater visibility. "We drew upon the expertise of drivers to ensure that the RH Series is the most driver-centric Class 8 re- gional-haul vehicle we've ever built," says Denny Mooney, senior vice pres- ident of global product development for Navistar. e cab wiring includes all-new harnessing and an in-cab power distri- bution module that is inside the truck, tucked away from the elements. All key service points under the hood, inside the cab and around the vehicle are de- signed for easy access and servicing, and many components have been engineered with longer intervals between required maintenance. e new single-canister aertreat- ment system is 60 percent smaller and 40 percent lighter than the prior system and also offers faster servicing. Built from the MAN D26 engine crankcase, the A26 outputs up to 475 hp and 1,750 lb.-. of torque. Interna- tional says the A26 is the quietest, most efficient engine in its on-highway lineup. At 2,299 pounds, it's the lightest engine in its class and is 55 pounds lighter than the N13 engine it will replace at the end of the year. e A26's design includes a compact- ed graphite iron crankcase – a North American first for a Class 7-8 truck – an aluminum flywheel housing that is shot- peened to prolong durability, composite valve covers and a hollow assembled camsha that features tool-grade steel lobes for added durability. RH Series improvements include fuel economy, turning radius, dash de- sign, visibility and noise reduction. Navistar will begin taking orders this month. The redesigned interior features a new premium gauge cluster with a digital driver display. Real-time monitoring of fuel economy and other important alerts are in clear sight. The new display also offers up to 15 customizable digital gauges.
