International Truck has launched the International RH Series, its new Class 8 regional haul tractor, powered by the new International A26 12.4L engine and designed to deliver best-in-class uptime, improved visibility and outstanding fuel economy. The new truck was unveiled during the ExpoCam truck show in Montreal, Canada recently.
New features of the RH Series include:
•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 for longer intervals between required maintenance.
•The new single-canister after-treatment system is 60% smaller, 40% lighter and simplified for quicker servicing.
The RH Series also was designed to provide a visible difference in safety and productivity for the driver. Drivers will benefit from redesigned side windows and mirrors that provide enhanced side visibility. The interior was conceived from a study of interaction points between driver and truck—everything from what a driver sees, to how he moves and reacts in virtually any situation. Features like a large swept-back windshield, optimized mirror placement and an aerodynamic sloped hood for a clearer view, can all contribute to greater visibility and an improved ride in the RH Series.
The RH Series was engineered to offer maneuverability that enables drivers to navigate tight city streets or cramped loading docks. It provides an inside wheel cut of up to 50 degrees, delivering a curb-to-curb turning radius of 27'-10".
In keeping with the company’s DriverFirst product design philosophy, International undertook extensive research with truck drivers, including driver clinics that gathered input from hundreds of drivers. International used this data to design an all-new interior, and identified multiple new and improved features that enhance driver appeal.
The redesigned interior features a new 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 in clear sight. The new display also offers up to 15 customizable digital gauges. In addition, the air horn was relocated back to its traditional, intuitive position over the driver door in response to overwhelming driver feedback.
The same aerodynamic improvements that boosted the RH Series’ fuel efficiency also yielded a four-Sone decrease in wind noise, which eliminates noise harshness for improved driver comfort. Together, aerodynamic and driveline improvements make the RH Series up to 6% more fuel-efficient.
Reducing the weight of the RH Series helps to boost productivity and improve efficiency without compromising strength and durability. Among the weight saving technologies like the single canister after-treatment device, the International Ride Optimized Suspension, and aluminum fuel tank hangers, the lighter, durable International A26 engine significantly reduces the overall weight of the RH Series.
The RH Series is powered by the new International A26, a 12.4-liter engine designed to provide uptime to the Class 8 market. Built from the MAN D26 engine crankcase, the A26 produces up to 450 horsepower and 1,750 ft-lbs of torque from a design that’s 600 to 700 pounds lighter than a traditional 15-liter big-bore engine.
The RH Series will be offered in multiple configurations, including daycab, 56-inch low-roof sleeper, 56-inch hi-rise sleeper, daycab with roof fairing, and 56-inch hi-rise sleeper with roof fairing. From a safety standpoint, the Bendix Wingman Advanced Collision Mitigation system comes standard in the RH Series—an industry first in the regional haul market, according to Navistar officials.
The company is taking orders and will begin production in early June. See www.internationaltrucks.com/RHSeriesMedia for further information.
