The Redesigned International HV Series: What Changed for Construction, Utility, and Municipal Fleets

International's medium-duty CV Series stops rolling off the line this month as GM and International wind down their joint manufacturing agreement, and most of the coverage of that transition — ours included — has focused on the direct replacement, the MV Series. Fair enough. But if your work sits closer to the top of Class 6 or reaches into Class 7 and 8 vocational territory — dump bodies, mixers, boom trucks, aerial devices — the International that actually deserves your attention right now is the HV Series, and it just went through a redesign worth understanding before you spec your next unit. This isn't a paper refresh. International changed the powertrain options, the cab, and the electrical architecture on a truck that's been earning its keep on severe-duty jobsites for more than two decades.

A Nameplate That's Been Doing the Dirty Work Since It Replaced the WorkStar

The HV nameplate isn't new — International rolled it out in 2018 specifically to replace the WorkStar, aiming for a truck drivers would actually want to climb into instead of just tolerate. What's new is this redesign, which International is positioning as the most significant update to the HV since that WorkStar handoff. The four-model lineup — 509, 609, 515, and 615 — spans a 27,000 to 75,000-lb. GVWR range, which puts it squarely between the MV Series on the lighter end and the severe-duty HX Series on the heavier, harshest-duty end.

If you've been cross-shopping an International HX Series for work that doesn't actually need HX-level abuse tolerance, the HV redesign gives you a real reason to look again before you commit to the more expensive platform.

The S13 Integrated Powertrain Changes What the 515 and 615 Can Do

The headline mechanical change sits on the 515 and 615 models, which now offer International's own S13 Integrated Powertrain — 370 to 515 horsepower and 1,250 to 1,850 lb-ft of torque, paired with the T14 Automated Manual Transmission and dual crawler gears. When International engineers the engine, transmission, and rear axle calibration together instead of bolting a third-party box behind their own engine, you get tighter shift logic, one warranty conversation instead of two, and real fuel economy gains based on International's own duty-cycle testing.

We've written before about what the S13 changed for HX Series mixer trucks, and the same logic applies here. The T14's dual crawler gears and Precision Maneuvering mode matter more than they sound: for a boom truck or aerial device working a tight municipal right-of-way, or a mixer backing into a residential pour, low-speed creep control without riding the clutch is the difference between a smooth setup and a truck that lurches. The 509 and 609 keep running Cummins B6.7 (up to 325 hp) and Cummins L9 (up to 400 hp) power for fleets already standardized on Cummins parts and service.

What Actually Changed in the Cab and on the Chassis

Past the powertrain, International rebuilt the cab around a double-sided galvanized steel structure, a sloped hood, and a panoramic windshield — a visibility upgrade that matters more on a municipal or utility route with pedestrians and cyclists in the mix than it does on a highway tractor. The premium gauge cluster now tracks axle loading and tire pressure in real time and throws safety alerts before a driver finds out the hard way at a scale house. Seats got a two-chamber lumbar system with pneumatic bolsters — not a glamorous spec, but ask any driver running an 8- or 10-hour shift in a dump truck cab what that's worth.

On the chassis side, International now offers up to three factory-rated lift axles from 8,000 to 20,000 lb., plus factory-installed PTO options — single or dual transmission-mounted, REPTO, FEPTO — instead of leaving that to an upfitter to sort out after delivery. That matters for lead time and warranty: a factory PTO is covered the same way the rest of the drivetrain is, where an aftermarket install can create a gray area the first time something fails. Diamond Logic's electrical architecture adds up to 30 customizable dash switches for body-builder integration, and five years of remote diagnostics with over-the-air programming comes standard — real uptime tools, not a marketing line.

HV vs. HX vs. MV — Where Each One Actually Fits

With three International vocational platforms now overlapping in places, it's worth being specific about where each one earns its spot. The MV Series is the direct CV Series replacement — Class 6-7, built for the service trucks, landscape dumps, and box-truck work the CV used to cover. The HX Series is International's severe-duty flagship, built for the punishing, off-road-adjacent work — quarry hauling, extreme mixer duty cycles — where frame strength and ground clearance matter more than anything else. The HV sits in between and, honestly, covers more everyday vocational applications than either: dump trucks, mixers, boom cranes, and aerial devices that need genuine Class 7-8 capacity and a factory-integrated powertrain, but don't need HX-level toughness or the premium that comes with it. If you're building out your first dump truck fleet, the HV is worth putting on the shortlist next to the T880, Granite, and 114SD Plus.

If You're Coming From a CV Series Truck, Don't Default to MV Without Checking HV First

Most of the CV Series conversations happening right now default straight to the MV Series, and for the lighter end of that CV range — service trucks, landscape dumps — that's the right call. But CV Series customers running closer to the top of that 16,000 to 23,400-lb. GVW range, especially anyone who's been quietly wishing their CV had a bit more capacity, should cross-shop the HV's 509 and 609 models before committing to MV. The Cummins B6.7 and L9 options on those models give you a real step up in GVWR without jumping all the way to an HX-level truck, and International's dealer network is committed to supporting CV customers through this transition regardless of which platform you land on next. It's worth a conversation with your dealer about duty cycle before you assume MV is the only path forward.

Renting This Class of Truck Is a Bad Plan When You've Got Overlapping Jobs

A boom truck, aerial device, or mixer chassis in this weight class isn't cheap to rent by the week, and every dollar spent on a rental buys you zero equity and zero resale value once the job's done. That math gets worse fast for utility contractors, municipal fleets, and demolition subs who run overlapping projects instead of one job at a time — you're either paying rental rates on two machines simultaneously or turning down work because your one rented truck is tied up on the wrong site.

Owning the truck outright, financed the right way, means the HV that's paying for itself on this month's municipal contract isn't standing in the way of bidding the next one. That's the real advantage BFC brings that a conventional lender usually doesn't: we can help finance your next HV, T880, or Granite while you're still paying down the last one, instead of making you wait five-plus years to qualify for a second loan. If your fleet already has more work lined up than trucks to run it, that's the conversation worth having before this quarter closes out.
