Curb weight keeps climbing across the American market as batteries and commercial-grade frames add pounds that old brochures never accounted for. Some names here are pure gasoline holdovers built for towing, while others are electric trucks and SUVs where the battery pack alone can outweigh a compact car. Here are twelve cars that carry the heaviest curb weights sold in America.
1. International CXT: The Heaviest Pickup Ever Sold
At 14,500 pounds, the International CXT is built on a commercial truck chassis borrowed straight from International’s medium-duty lineup, not a car or light-truck platform, which is why it dwarfs anything else that has ever carried a pickup badge onto a public road.
International only built the CXT for a handful of years in the mid-2000s before folding its consumer truck line entirely, so surviving examples now trade among collectors as a rolling novelty rather than something anyone drives daily to work.
2. GMC Hummer EV: A Battery Pack That Weighs as Much as a Sedan
The GMC Hummer EV tips scales at roughly 10,000 pounds, and about 3,000 of those pounds come from the battery pack alone, a single component that weighs more than many compact cars weigh in their entirety.
That mass gives the Hummer EV supercar-level acceleration off the line thanks to its enormous motor output, but it also forces the truck’s tires, brakes and suspension to work far harder than they would on a comparably sized gas pickup.
3. Chevrolet Silverado EV: A First Edition That Broke 9,000 Pounds
Testers at Hagerty put a First Edition RST Chevrolet Silverado EV on a scale and recorded 9,119 pounds, more than two tons heavier than a comparably equipped gasoline Silverado rolling off the same assembly line.
GM markets the electric Silverado as a capable work truck first and an EV second, but that curb weight quietly pushes it closer to medium-duty commercial territory than the pickup badge on its tailgate suggests to a casual buyer.
4. Cadillac Escalade IQ: A 205-kWh Pack Under a Luxury Badge
The Cadillac Escalade IQ carries a 205-kWh battery pack, one of the largest fitted to any production vehicle, and reviewers estimate the finished three-row SUV lands close to 9,000 pounds once options are loaded in.
Cadillac wraps that mass in quilted leather, a curved 55-inch OLED dashboard display and adaptive air suspension, proof that electrification adds substantial pounds even to vehicles that were never engineered around hauling or towing chores.
5. Ford F-350 Super Duty: 7,400 Pounds Before a Single Passenger Boards
A diesel Platinum 4×4 Ford F-350 Super Duty scales about 7,400 pounds with an empty bed and no driver aboard, Hagerty found when it weighed the truck for its own published review.
Hook up a loaded trailer or fill the bed with gear and that number climbs quickly, which is precisely the point of a heavy-duty truck engineered around maximum towing capacity rather than around fuel economy or nimble handling.
6. Rivian R1T: 7,000 Pounds With Supercar Acceleration
Federal safety researchers at IIHS cite the Rivian R1T at roughly 7,000 pounds, heavy enough on its own to worry crash-safety engineers even as the electric pickup sprints to highway speed like a dedicated sports car off a stoplight.
IIHS has flagged that exact combination of extreme mass and rapid acceleration across the entire heavy-EV class in its published research, arguing publicly that it changes crash physics for pedestrians and smaller vehicles sharing the same road every day.
7. Ford Excursion: The Last Giant Standing Among Gas SUVs
Built on a Super Duty pickup frame rather than a conventional SUV platform, the Ford Excursion remains so large that only the newer electric Hummer EV SUV now manages to outweigh it on public roads today, more than twenty years after launch.
Ford discontinued the Excursion more than two decades ago, partly over persistent public criticism of its size and fuel appetite, yet no gasoline-powered SUV built anywhere since has matched its sheer physical bulk or interior volume.
8. Ford F-150 Lightning: An 1,800-Pound Battery Hiding in a Pickup Bed
Depending on trim and battery size, the Ford F-150 Lightning weighs anywhere from 6,015 to 6,893 pounds, with an 1,800-pound battery pack driving most of that considerable spread between the base and extended-range versions.
That range means two Lightnings parked side by side on the same dealer lot can differ by nearly 900 pounds before either truck carries a single passenger or a single pound of payload in its bed.
9. Mercedes-Benz G 580 with EQ Technology: A German Icon Gains Nearly a Ton
Listed at 3,085 kilograms in official Mercedes-Benz specifications, the Mercedes-Benz G 580 with EQ Technology comes in around 6,746 pounds, the electric-era price of keeping the boxy, decades-old G-Class silhouette essentially unchanged from the outside.
Mercedes kept the upright body panels and portal axles that define the G-Class largely intact for this all-electric version, so the extra weight comes almost entirely from swapping a combustion engine and fuel tank for a large battery pack instead.
10. Tesla Cybertruck: A Stainless Shell Riding on a 1,590-Pound Pack
The Tesla Cybertruck carries a battery pack that alone weighs 1,590 pounds, bolted beneath an unpainted stainless-steel exoskeleton that Tesla built thick enough to double as structural armor rather than ordinary stamped sheet metal.
Tesla engineered those flat body panels heavy enough to skip traditional paint booths and stamping presses entirely, another deliberate design choice on the Cybertruck that adds meaningful curb weight rather than trimming any of it down.
11. Hummer H2: Too Heavy for Normal Fuel-Economy Testing
At around 6,400 pounds, the Hummer H2 crossed a specific curb-weight threshold that put it beyond the reach of standard EPA fuel-economy testing procedures entirely during its entire production run in the 2000s.
That regulatory exemption became one of the loudest public criticisms leveled at the H2 during its heyday, since buyers signing a loan for one never once saw an official government mileage sticker anywhere on the window at the dealership.
12. Rolls-Royce Cullinan: 382,000 Dollars of Twin-Turbo V12 Muscle
The Black Badge Rolls-Royce Cullinan weighs 6,069 pounds, moved down the road by a 563-horsepower twin-turbocharged V12 engine tucked beneath a body largely finished by hand at the company’s English factory.
Rolls-Royce leans into that heft rather than trying to hide it, marketing the Cullinan’s sense of isolation and planted, weighty ride quality as a core part of the overall luxury experience buyers are actually paying for at that steep price.
