The International DuraStar, originally introduced as the International 4000 Series, is a line of medium-duty trucks produced by Navistar International. First produced in 2002, it is the successor to the 4000 Series of the 1990s, Competitors include Xos MDXT, Freightliner Business Class M2, Ford F-650/F-750 Super Duty, Dodge Ram 6500, Hino 600, Chevrolet Kodiak, Peterbilt 337, Peterbilt 537, Kenworth T-370, Kenworth T-380, Sterling Acterra, Mack MD, Dina HTQ, and KrAZ-5233.

It is available in three variants, which are built on the same chassis. They differ in engines, drivetrains, brakes, and cargo capacity. It is a popular commercial platform used in a wide variety of applications, such as emergency services, towing, flatbed truck and as a cargo box truck. Variants of the Durastar are commonly used as a platform for both school buses and commercial buses.



Blue Diamond Truck Alliance[]

In early 2001, Navistar entered into a 50/50 joint venture to produce commercial vehicles with Ford Motor Company,[1] officially named Blue Diamond Truck, LLC. Under the agreement, Navistar assembled medium-duty trucks for both companies in its facility in General Escobedo, Mexico.[2]

Though externally different, both Ford and Navistar model lines would share a common chassis; the medium-duty Ford F-Series (which had already entered production in 2000 at General Escobedo[2]) shared its cab with the F-Series Super Duty line (F-250 through F-550). Though smaller F-Series vehicles used Navistar-supplied diesel engines, medium-duty Fords used engines supplied by Cummins and Caterpillar.

Serving as the debut line of the NGV (Next-Generation Vehicle) cab structure, the new International 4000 series sourced its engines from within the company, carrying over the T444E V8 and DT466E I6 diesel (later VT365, DT466, and MaxxForce engines) from the previous 4000 series (sharing other commercial-grade drivetrain components with Ford and other medium-duty vehicles).

In 2015, Ford ended its stake in the joint venture; as part of a redesign, production of medium-duty trucks was relocated from Mexico to Ohio (replacing the E-Series van),[3] with Navistar continuing production at General Escobedo.

4000 series (2001-2007)[]

In February 2001, Navistar released its all-new 4000 series (after-International Harvester Auto Wagon, International F-Truck, International Model S, International Six Speed, International Harvester A-3, International Harvester B-3, International C-30 Truck, International CS-30 Truck, International Harvester D-Series, International Harvester K series, International Harvester KB series, International Harvester L-Series, International Harvester R Series, International Harvester Loadstar (1962-1971), International Harvester Loadstar (1972-1978), International Harvester S-Series Medium-Duty (1978–1989), and International 4000 Series (1989–2002)), dubbed as "High Performance Trucks". Developed in the Blue Diamond Truck joint venture with Ford, the 4000 series marked the first completely new truck line from International since the 1979 S series. Sharing its chassis with the medium-duty Ford F-Series (introduced in 2000), the International 4300/4400 retained the DT466 and DT530 diesels of their predecessors. For versions equipped with automatic transmissions, electronics for the engine and transmissions were retuned to optimize throttle and shifting response, to increase both performance and fuel economy. To increase forward visibility, the size of the windshield was increased by over 60%, with additional attention paid to improvements in ventilation.

At the launch of the 4000 series, the standard 4300 and higher-GVWR 4400 were introduced as replacements for the previous 4900 model series. In 2002, the lower-GVWR 4200 was introduced as the replacement for the 4700 series, marking the introduction of the VT365 engine. In 2006, the 4100 was introduced, expanding the model line into the Class 5 segment; the model was discontinued a single year of production. The 4200, 4300, and 4400 were produced in both a standard and low-profile frame. The 4400 was also produced in a semitractor; sitting 4 inches higher than the chassis truck, the 4400 tractor was the only version offered with the DT570 engine as an option.

DuraStar (2008-2018)[]

For 2008, coinciding with the introduction of the International ProStar and International LoneStar, Navistar revised the branding of its truck model lines. In line with nomenclature previously used by International Harvester, truck lines adopted a "xxxxStar" naming scheme, with the 4000 series adopting the DuraStar model name. This change was completed in its entirety for the 2010 model year. In another revision, to comply with 2007 emissions regulations, the powertrain lineup underwent extensive revision, with the 6.0L VT365 V8 replaced by the 6.4L MaxxForce 7 V8. The DT inline-6 engine family underwent revisions as well, with the DT466 becoming the MaxxForce DT and the DT570 becoming the MaxxForce 9, adopting four-valve cylinder heads and exhaust gas recirculation to reduce emissions.

Second generation[]

For 2019 model-year production, the medium-duty DuraStar product range underwent its most extensive revision since its 2001 debut and was renamed to International MV Series. In line with revisions to International Class 8 product lines, the MV Series introduced a number of updates to the cab interior. Externally distinguished by larger doors and side windows, the quarter windows of the DuraStar were replaced with a single-piece side window with a lower windows. The dashboard underwent extensive changes, with the previous instrument panel replaced by a reconfigurable digital display.

The International MV Series continues its use of Cummins diesel engines, with the Cummins B6.7 and L9 offered, depending on configuration.

In 2021, the MV Series was updated with a redesigned hood and bumper.

Hybrid trucks[]

In 2007, Navistar's International Truck and Engine Corporation became the first company to enter hybrid commercial truck production, with the International DuraStar Hybrid diesel-electric truck. International Truck and Engine teamed with the Hybrid Truck Users Forum (HTUF), a consortium of utility industry customers, Eaton Corporation, the US Federal Government and the Calstart organization to assist with the cost of bringing the technology to market. It also provides direct customer feedback and support. [10]
