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.[1] Although not officially designated by the company as the replacement for the CityStar LCF cabover, the TerraStar is of similar dimensions and GWVR.

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 International 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. Through its entire production, the model line was offered with a MaxxForce 7 turbodiesel V8 paired with a Allison 1000 6-speed automatic.[2] Originally configured solely with a single rear drive axle, four-wheel drive became available as an option in May 2013.[3]

Variants

Bus

From 2010 to 2015, the TerraStar chassis was used by Navistar subsidiary IC Bus to develop its smallest vehicle ever produced. Intended largely as a heavier-duty alternative to vehicles produced on Ford E-450 and GMC Savana chassis, IC Bus introduced cutaway-cab buses derived from the TerraStar. The company marketed two versions, including the AC-Series shuttle bus and the AE-Series school bus.

In line with its truck counterpart, the AC/AE was discontinued at the end of 2015, following the withdrawal of the MaxxForce 7 engine.

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.[4]
