nternational isn’t a name often associated with modern pickup trucks, having built its last Light Line pickup in 1975. Even though it was a poor seller, this truck wouldn’t represent International’s last stab at consumer pickups. That honor belongs to the MXT, an utterly excessive blend of medium-duty commercial truck and military vehicle that dwarfed even the humongous Hummer H1.
Launched in 2007, according to an archived Navistar release, as the final member of International’s Extreme Truck (or XT) series, the MXT was closely related to International’s MXT-MV armored personnel carrier, and derived its M either from the military model or simply the word most, depending on who you ask. It was based on the company’s DuraStar medium-duty truck chassis, making it ludicrously large for a pickup truck, coming in at 252 inches long, 96 wide, and 91 tall. That makes it around the length of a crew-cab, short-bed 2021 Ford Super Duty, but about a foot taller and more than one foot wider—and approximately 20 inches longer, 8 inches wider, and a staggering 11 inches taller than a new Ram 1500 TRX. This is a big boy.
At more than 10,500 pounds, its engine is quite thirsty, too. Anecdotes online suggest it got around 10 mpg, giving it a total range of about 400 miles on a full 40-gallon tank. Said tank fed a 6.0-liter Navistar VT365 turbodiesel V8—shared at the time with the Super Duty—which in this application produced an advertised 300 horsepower and 530 pound-feet of torque. This is communicated through a five-speed Allison 2200 RDS automatic transmission to a two-speed transfer case, likely a Magna MP1528 according to service literature. These all allowed the MXT a then-impressive two-ton payload rating, and the capability to haul up to 15,500 pounds. For the full story, check out this article from The Drive.
