International P roStar is losing its Plus suffix, but remains International's principal aero-style highway model with daycab and several sleeper versions. It's offered with Navistar MaxxForce 13 and Cummins ISX15 diesels, both with Cummins-sourced selective catalytic reduction equipment.The traditionally styled 9900i and retro-fashion LoneStar come only with the ISX15.TranStar 8000 regional tractor uses the MaxxForce 13 and is available with Cummins Westport ISL G. It's also built for bulk hauling and heavy beverage delivery. International's Class 8 vocational offerings are the WorkStar 7000 and PayStar 5000 using Navistar's medium-, medium-heavy and heavy-duty MaxxForce diesels that will soon get Cummins SCR equipment. PayStar is also available with Cummins' ISX15. MaxxForce 11 was dropped earlier this year and its 365- to 390-horsepower ratings taken be fewer of them. "We're seeing some fleets moving away from the 'large car' long-haul configurations to lighter and less expensive mid-size sleeper equipment that operate more economically," says Jerry Warmkessel, Mack's highway product marketing manager. "In some cases, based on location and number of terminals, a customer may have day cabs actually replacing sleeper equipment." Engines changing These more regional fleets no longer have to worry about having larger engines that can easily transverse the country over the Rocky Mountains, Warmkessel says, "In these cases smaller, lighter, more fuel-efficient engines will do the job, increasing the opportunity for greater profits for the carrier." Greater output from 13-liter-class diesels, now available with 500 or more horsepower and 1,850 pounds-feet of torque, along with decent durability, are pleasing drivers and convincing fleet managers to buy more of them – something predicted several years ago by people at Mack and other OEMs. All builders now have their own diesels with this displacement. Most rely on Cummins for the larger 15-liter still preferred by customers wanting million-mile life or regularly hauling heavy loads or operating in more challenging terrains. Mack sells only its own 11- and 13-liter diesels, plus a 16-liter model that it gets from Volvo Powertrain. Volvo sells its versions of those engines, but also offers the Cummins ISX in its VN series. However, 80% of Volvos now get Volvo-brand diesels.
