This Terrastar 4x4 still has the Dana front axle with chain-driven transfer case, but in February 2013 buyers will be able to get the truck with a gear-driven Fabco transfer case.
Navistar swept the competition during this week's annual American Truck Dealers (ATD) Convention and Exposition in New Orleans with the International ProStar with Cummins ISX15 engine with selective catalytic reduction (SCR) named "2014 Heavy-Duty Commercial Truck of the Year" and the International TerraStar 4x4 named "2014 Medium-Duty Commercial Truck of the Year."
Judged by a panel of journalists from leading truck publications in North America, Truck of the Year is selected based on a number of criteria, including innovation and design, safety, and driver and owner satisfaction. For the Heavy-duty category, the Class 8 International ProStar beat out the Kenworth T880 Vocational Truck with PACCAR MX-13 engine and Peterbilt Model 579. The TerraStar 4x4 beat out the Hino 195h-DC, Kenworth Class 6 K370 Cabover and Peterbilt Model 220 for Medium-duty Truck of the Year.
Re-introduced in December 2012 with SCR, the International ProStar with Cummins ISX15 offers aerodynamic innovations for improved fuel economy. Offering ratings up to 550 horsepower and 1850 lb.-ft. of torque, the ISX15 engine's variable geometry turbocharger enhances response and control with electric actuation for infinite adjustment, providing exact boost at any rpm.
The TerraStar 4x4 gives work truck buyers a wide range of commercial duty features while sharing the same rugged, durable and hardworking DNA as the medium-duty International DuraStar. Designed to last twice as long as competitive models, the TerraStar 4x4 offers high strength, low-allow frame rails at 80,000 psi and includes a severe service transfer case from Fabco, a leader in all-wheel drive transfer cases and steer-drive axles for medium and heavy-duty vehicles. Due to the uniquely robust design of Fabco's gear-driven TC-28 transfer case, TerraStar 4x4 owners will have vehicle capabilities exceeding other Class 4 and 5 truck offerings in the market.
Powered by the 300 horsepower, 660 lb.-ft. torque 6.4 liter MaxxForce 7 engine, the compacted graphite iron (CGI) engine block provides added strength, while a commercial-duty Allison Optimized 1000 Series transmission, including the available 1350 model, optimizes power output.
The TerraStar features the International Diamond Logic electrical system, one of the most advanced electrical multiplexing architectures available in commercial trucks. Diamond Logic maximizes ease of body integration and helps deliver a number of smart, customizable features for added convenience and safety - such as automated pre-trip inspections, headlights on with wipers, interlocks, programmable switches and more depending on the application.
