International Truck today launched its new RH Series Class 8 regional haul tractor at ExpoCam in Montreal, Canada. The RH Series is powered by International’s new A26 12.4L engine, which the company says produces up to 450 horsepower and 1,750 lb.-ft. of torque. The RH Series offers several configurations, including day cab, 56″ low roof sleeper, 56″ hi-rise sleeper, day cab with roof fairing, and 56″ hi-rise sleeper with roof fairing. The Bendix Wingman Advanced collision mitigation system comes standard in the RH Series. International is taking orders and will begin production in early June. International used Facebook Live to introduce the truck on social media.
