ST. LOUIS - Navistar unveiled the International TerraStar Class 4-5 commercial truck at a press event at the National Truck Equipment Association (NTEA) Work Truck Show. With a wide range of commercial-duty features - from its commercial-duty MaxxForce7 V-8 diesel engine to the largest, roomiest cab available - the International TerraStar sets a new standard in the Class 4-5 truck market.

"The International TerraStar comes from the same blood lines as the rest of our commercial truck line-up," said Jack Allen, president, Navistar's North American Truck Group. "Its commercial-duty design will change the game in the work truck market by offering one of the most capable, most versatile and most drivable trucks in its class."

At the heart of the new International TerraStar is its all-new 300 horsepower, 6.4L MaxxForce7 V-8 engine, delivering 660 lb.-ft. torque. This engine features a compacted graphite iron (CGI) block which offers high strength without added weight. The MaxxForce7 will be matched with a commercial-duty Allison 1000 transmission to optimize its power output.

The TerraStar features MaxxForce Advanced EGR emissions technology, the only no-hassle emissions technology in its class. With MaxxForce Advanced EGR, customers won't have the worry or inconvenience of finding or filling liquid urea. And, with no added SCR aftertreatment equipment, the TerraStar provides a clean and clear chassis for easy body and equipment mounting, not to mention less added weight.

While built on a strong and durable commercial-duty platform, the TerraStar is also easy to operate. The TerraStar features best-in-class visibility-28 percent more than the market leader. And, with an industry-best 107-inch BBC (bumper to back-of-cab) length and a 44-foot curb-to-curb turning radius, it offers outstanding maneuverability in even the tightest work environments.

The TerraStar features a true commercial-duty truck cab with 30-percent more cab interior space than the market leader, allowing plenty of room for three adults to fit comfortably in the front seat. The TerraStar will also be offered with optional extended cab or crew cab configurations.

The TerraStar also delivers unmatched serviceability with a commercial style tilt-away hood that offers unobstructed access to the engine compartment, making routine and schedule maintenance quick and easy.

In addition, the International 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.

The TerraStar will initially be available with a 4x2 drivetrain, with a 4x4 drivetrain planned for 2011.

"With the introduction of the International TerraStar powered by the MaxxForce 7, there is no other truck manufacturer in the industry today with as complete a line-up of integrated trucks and engines," Allen added. "The addition of TerraStar gives us a product line-up that can serve virtually any truck need, spanning from Class 4 to Class 8."
