Twelve vehicles were included in an online ballot and voted on by professional fleet managers, who were asked to consider which medium-duty truck model best fit their fleet requirements, including application effectiveness, durability, quality, servicing, maintenance, and lifecycle costs.
The Class 4-5 TerraStar 4x4 provides frame rail strength of 80,000 psi, a commercial-duty Allison Optimized 1000 Series transmission, a Fabco TC-28 gear-driven transfer case, and a five-year unlimited mile warranty.
Michael Cerilli, vice president of marketing for Navistar, accepted the award during a presentation at the Work Truck Show.
“We’re honored for TerraStar 4x4 to be named Work Truck magazine’s Medium-Duty Truck of the Year by fleet managers throughout our industry,” Cerilli said. “International Trucks have long been recognized as a leader in the medium-duty class, and now to be recognized in the Class 5 segment is rewarding.”
Navistar launched a truck configurator for the TerraStar (in addition to the ProStar and DuraStar) in January, allowing customers to design, build, and customize the truck’s cab, exterior, interior, and powertrain on its website.
Launched in 2010 in a 4x2 configuration, the International TerraStar took center stage giving work truck buyers a new product with a wide range of commercial-duty features. Now, the 4x4 enables International Truck to capitalize on the other half of the market, so TerraStar is poised to win over an even broader range of customers.
“The TerraStar is the smaller sibling to the DuraStar, the best-selling medium-duty model throughout the past two decades, leveraging the same platform and commercial grade components,” said Bill Kozek, Navistar’s president, North American Truck and Parts. “The TerraStar shares the same rugged, durable and hardworking DNA, making it in a class unto itself. The TerraStar 4x4 will deliver additional commercial duty capability for a wide range of customer needs, including construction, utility, landscape, and other off-highway applications.”
Powering the Medium-Duty Powerhouse
At the heart of the TerraStar 4x4 is its 300 hp, 6.4L V-8 engine, delivering 660 lb.-ft. torque. This engine features a compacted graphite iron (CGI) block, which offers high strength without added weight, according to the manufacturer.
With 38-percent more visibility and 30-percent more cab interior space than the competition, the TerraStar also offers enhanced maneuverability for tight work environments, according to the manufacturer. The 4x4 features 11-inches of additional headroom and is 8-inches wider than its closest competitor.
In addition, the commercial grade TerraStar cab, available in extended cab or crew cab configurations, is designed to be extremely durable and is constructed with double-sided, galvanized high-strength steel protected by a five-step, professional-grade coating process to resist corrosion.
The TerraStar includes the International Diamond Logic electrical system. With Diamond Logic, the engine, transmission, instrument panel, and other vehicle components continually communicate with each other electronically. By monitoring critical vehicle functions and relaying information to the driver in real-time, Diamond Logic ensures safe, efficient vehicle operation.
Diamond Logic delivers a number of customizable features for added convenience and safety, such as automated pre-trip inspections, headlights on with wipers, automatically engaged safety interlocks, programmable switches, and more, depending on the application.
The TerraStar 4x4 is designed to last twice as long as the pickup truck platforms offered by competitors, according to the manufacturer. Its huck-bolted cross-members deliver best-in-class framerail strength of 80,000 psi, a commercial-duty Allison Optimized 1000 Series transmission for maximum power output, and a Fabco TC-28 gear driven transfer case — the only gear driven transfer case in the market.
Fabco is an industry leader in all-wheel-drive transfer cases and steer drive axles for medium- and heavy-duty vehicles, according to International. The forged helical gearing and roller bearings give high torque and horsepower capacities while offering a quiet and smooth driving experience. A precision, cast iron housing offers rugged durability with optimized weight.
Mated to the 6.4L V-8 engine, the Allison Optimized 1000 Series transmission features shift energy management (SEM), load-based shifting scheduling (LBSS), and automatic “neutral.”
