International TerraStar


The International TerraStar is a product line of medium duty trucks that was manufactured by International Trucks from 2010 to 2015. The smallest conventional-cab truck ever produced by Navistar, the TerraStar is a Class 5 medium-duty truck. Although not officially designated by the company as the replacement for the CityStar LCF cabover, the TerraStar is of similar dimensions and GWVR.
Slotted in the Class 5 range, the TerraStar was marketed against both pickup-based vehicles like the Ford F-550 and Ram 5500 as well as conventional-cab trucks like the Freightliner M2, Kenworth T170, and Hino 185. Sharing a common cab and powertrain with the larger DuraStar, the TerraStar also took the place of the light-GVWR 4100 series within the DuraStar range.
In 2015, Navistar moved away from EGR-based emissions systems, leading to the discontinuation of the MaxxForce 7 engine. As the TerraStar was left without an engine, production of the vehicle was ended at the end of 2015.
In 2019, International re-entered the Class 4-5 truck segment in a joint venture with General Motors, introducing the International CV, produced alongside the Chevrolet 4500-6500HD medium-duty line of trucks.

Model overview

Sharing its cab with the DuraStar, WorkStar, TranStar, and ProStar, the TerraStar is distinguished by its low-profile cab and hood. To lower the cab on the frame, the fuel tanks were moved from below the cab to behind the cab on the frame rails; the TerraStar is distinguished from the DuraStar by the use of square sealed-beam headlights. As with the larger International trucks, the TerraStar was available in two-door, extended-cab, and crew-cab configurations, with a wide variety of bodies fitted by second-stage manufacturers.
In contrast to the DuraStar, the TerraStar was sold with relatively few powertrain combinations, available solely with a single rear axle; in 2011, 4-wheel drive became an option. At its launch, the 300hp MaxxMorce 7 V8 diesel was the only engine. The Allison 1000 6-speed automatic was the standard transmission, configured to customer use.

Variants

Bus

Navistar subsidiary IC Bus used the TerraStar chassis in cutaway cab form to develop its smallest bus ever produced, largely as an alternative to vehicles produced on Ford E-450 and GMC Savana chassis.
In 2010, the company launched the IC AC-Series shuttle bus, with the IC AE-Series school bus following soon after. As the chassis was not packaged separately from the body, the IC buses based on the TerraStar would not take significant market share from established market players like Ford and GM.
The IC AC/AE was discontinued as the TerraStar ended production in 2015.

Vehicle conversions

Although never offered as a consumer vehicle, during its production, the International TerraStar served as a donor chassis for second-party conversions. In a configuration similar to the larger International XT trucks, the crew-cab TerraStar was converted by Elkhart, Indiana-based Midwest Automotive Designs to a pickup truck or a four-door SUV.
