GM officially unveiled the 2019 Chevy Silverado HD 4500, 5500, 6500 medium duty trucks earlier this year. The new trucks are coming on sale very soon at the end of 2018. GM collaborated with Navistar/International on the new chassis, but the International version of the truck is yet to be debut. Granted the differences between the two versions of the truck will be very minor.

TFLtruck team recently spied this International/Navistar prototype of the truck loaded heavy with payload and a trailer. This truck is at the bottom of the Ike Gauntlet™ – world’s toughest towing test in Colorado. It’s an 8-mile stretch of I-70 between Dillon, CO and the Eisenhower/Johnson tunnels. It’s a 7-percent grade of interstate that goes to 11,158 feet above sea level.
The 6.6L Duramax turbo-diesel V8 in this truck is rated at a class-leading 350 horsepower and (not class-leading) 700 lb-ft of torque. The truck comes several weight ratings, body styles, and driveline configurations. You can get a single cab or a crew cab, 2WD or 4×4, and several different wheelbase/length choices.
The Chevrolet version of the start will start at $46,970. We do not yet have the numbers on the International/Navistar version of the truck.
Here are all the other details we know so far about GM’s come back into the medium truck segment, after a nearly 10-year absence.
