Navistar initially launched the MV Series at the 2018 Work Truck Show to replace the company’s DuraStar medium-duty truck. The MV Series has now been redesigned to further enhance safety capability and body integration.
The MV Series was purposely designed for increased maneuverability, visibility and safety. An aerodynamic hood and breakaway mirrors provide greater visibility while optional LED headlights provide longer life and improved visibility.
To further improve safety, the MV Series offers the option of Bendix Wingman Fusion System technology which includes adaptive cruise, enhanced collision mitigation, multi-lane vehicle braking, stationary object alert, lane departure warning and front radar and cameras. The Bendix BlindSpotter Collision Warning System is equipped with side object detection alert. An optional premium gauge cluster is required with collision mitigation and it is customizable for the driver.
Diamond Logic Allows Customization
The Diamond Logic multiplex electrical system has always been a point of product differentiation for Navistar products. It allows for customized programing for driver and equipment protection and ease of body integration. But Diamond Logic is not just about body and chassis interlocks, which had been the company’s specialty since the system was launched in 2001. The Diamond Logic system now includes a pre-trip light inspection that can be performed at the touch of a button, getting customers on the job faster. There is also an external regen warning and additional equipment protection with hydraulic power take-off (PTO) shutdown and an outrigger stowed interlock.
There are many safety features built in, including programmable interlocks and optional collision mitigation technology.Navistar
“Our International Diamond Logic electrical system streamlines chassis and body equipment integration and allows you or the driver to program automated tasks,” says Chad Semler, director of product management, Navistar. “This means more equipment protection and increased crew safety.”
Design Change Accommodates Frame Extensions
A high efficiency cooling module eliminates mega-brackets, enabling integrated front frame extensions and an improved snowplow upfit offering. Hood mounted splash panels and on-engine air cleaner provide improved under-hood access while an optional under-hood work light is available for improved visibility during daily maintenance checks.
Navistar has designed a solution for applications that typically require a stationary grille, such as snow plows and winches. “A driver-orientated feature is a partially opened hood, at about 30 degrees instead of hood hatches, which can be used for not only snowplow applications, but also for hose reel and winch applications,” says Semler. “It provides easy access to all critical fluids without the awkwardness of a hood hatch. The hood can be opened fully, but the detent aides in doing daily fluid checks.”
Chassis components were relocated for additional clean CA configurations. The whole truck was reconfigured to allow easier body integration. For safety on the jobsite there are vehicle and component interlocks, backup alarms and optional safety systems.
Focus on the Cab
Inside the cab, a stalk shifter which allows drivers to manually shift and apply the Jake Brake without having to look down and take their eyes off the road,” says Semler. “It allows for a third occupant to sit without bumping their knees. It also allows for an Allison 1000 or 2000 Series transmission with a wing panel, which creates better ergonomics.”

The cab itself has better corrosion protection with InterCoat Chemguard standard on the cab floor as well as an optional LINE-X offering for particularly tough environments. InterCoat Chemguard acts like a self-healing layer of skin on the cab. The chrome-zinc coating will maintain corrosion protection despite cuts and scratches. “Uptime is improved because no holes are pierced in the cab after the primer coat,” notes Semler. “We also reduce joint count in the number of mechanical fasteners and applied a weld through epoxy sealant on most joints.”
Uptime a Priority
Navistar has worked with Cummins to align and extend service intervals with the two engine options, a Cummins B6.7 or a Cummins L9. This results in fewer trips to the service department. Both the Cummins B6.7 and Cummins L9 have undergone technical improvements like on-board diagnostics and emissions updates. The Cummins B6.7 offers ratings of 200 to 325 hp and torque from 520 to 750 lb.-ft. The Cummins L9 produces 260 to 380 hp and pumps out torque from 860 to 1,250 lb. ft. Transmission options include Allison 1000, 2000 or 3000 automatics; Eaton Fuller 10-speed automated manual or Eaton Fuller 6-speed or 10-speed manuals.
The International MV Series is supported through the Navistar OnCommand Connection remote diagnostic system. This gives customers the option to receive real time information to protect their assets through GPS and geofencing. Actionable information is provided via vehicle health reports. There is also the option for customers to add International 360, a service communications platform that simplifies communication with the International service network
