International » RH Series
International Trucks rolled out its RH Series, a new Class 8 regional-haul tractor at the 2017 ExpoCam truck show. RH Series trucks are equipped with the International A26 12.4L engine and feature some design improvements aimed at improving uptime, including reliability and serviceability enhancements. The A26 engine is built from the MAN D26 engine crankcase and it produces up to 450 horsepower and 1,750 lb.-ft. of torque from a design that's 600-700 pounds lighter than a traditional 15L big bore engine.
The RH was also designed with driver visibility in mind with new windows and mirrors to improve side visibility. It has features like a large swept-back windshield, optimized mirror placement, and an aerodynamic sloped hood for a clearer view, were aimed at improving visibility in the RH. The interior also features a premium gauge cluster with a digital driver display that places everything within reach of a driver, while offering real-time monitoring of fuel economy and other important alerts.
Maneuverability was also improved in the RH. An inside wheel cut of up to 50 degrees provides a curb-to-curb turning radius of 27 feet, 10 inches to help drivers navigate city streets. Aerodynamic improvements in the RH Series have decreased wind noise to improve driver comfort in the cab while also yielding up to a 6% improvement in fuel efficiency. In addition, weight reduction was achieved by leveraging such technologies as a single- canister aftertreatment device, the International Ride Optimized Suspension, and aluminum fuel tank hangers, as well as the lighter A26 engine.
The RH Series will be offered in multiple configurations, including day cab, 56-inch low roof sleeper, 56-inch hi-rise sleeper, day cab with roof fairing, and 56-inch hi-rise sleeper with roof fairing.
