What Is the Heaviest Car or Truck?

The heaviest truck ever built is the BelAZ 75710, an off-highway ultra-class mining dump truck from Belarus that weighs roughly 360 metric tonnes (about 795,000 lb) empty and can reach around 810 tonnes (about 1.79 million lb) fully loaded. For road-legal trucking on public roads, Australia’s multi-trailer road trains are among the heaviest combinations, with permitted gross masses well over 100 tonnes on designated routes. Among consumer pickups, the GMC Hummer EV is currently one of the heaviest, at about 9,063 lb (4,111 kg) curb weight. This article explains the distinctions behind “heaviest” by category, because what counts as a car or a truck—and where it can operate—changes the answer.

Why “Heaviest” Depends on Category

“Car” and “truck” span very different vehicle classes. Mining trucks operate off-highway with almost no weight limits, road-going commercial trucks are constrained by national and regional regulations, and consumer vehicles (including pickups, often called “light trucks” in North America) must balance capability, safety, and emissions rules. Understanding which category you mean clarifies which record-holder applies.

The Heaviest Truck Ever Built: BelAZ 75710

The BelAZ 75710, introduced in the 2010s, holds the crown for the heaviest truck. Designed for open-pit mining, it uses twin diesel engines powering electric drive motors to haul extraordinary loads. Its headline figures come from its design purpose: carrying ore efficiently in environments where road-legal limits don’t apply.

Key figures for BelAZ 75710 include:
– Empty (curb) weight: about 360 metric tonnes (≈795,000 lb)
– Payload capacity: up to 450 metric tonnes (≈992,000 lb)
– Gross vehicle weight (fully loaded): roughly 810 metric tonnes (≈1.79 million lb)

While other giants like the Caterpillar 797F and Komatsu 980E approach these numbers, the BelAZ 75710 remains the benchmark for sheer on-vehicle mass and payload in the off-highway category.

The Heaviest Road-Going Trucks

On public roads, the heaviest “trucks” are limited by law to protect infrastructure and ensure safety. Maximum allowable weights vary by country, road class, number of axles, and whether a vehicle has special permits. Below is a snapshot of typical upper bounds for heavy truck combinations in major regions, illustrating how “heaviest” differs by jurisdiction and configuration.

• United States: Most Interstate combinations are capped at 80,000 lb (≈36.3 t) gross; higher limits can apply off-Interstate or by permit in certain corridors (some states allow 105,500 lb or more with extra axles and permits).
• Canada: Provincial rules allow heavier multi-trailer “turnpike” doubles on designated routes, commonly up to about 63,500 kg (≈140,000 lb) gross.
• European Union: Standard semi-trailers are typically limited to 40–44 tonnes gross, with “European Modular System” combinations permitted up to 60 tonnes in participating countries; Nordic countries allow higher masses on specified routes (commonly 64–76 tonnes, with higher limits under specific national programs).
• Australia: On approved roads, B-doubles and triples can exceed 60 tonnes; designated road-train routes regularly accommodate combinations well above 100 tonnes, and, under special permits for specific operations and corridors, masses can surpass 150 tonnes.

In practice, Australia’s road-train network produces some of the heaviest road-legal combinations in the world, especially in remote freight and resource corridors, whereas North America and much of Europe prioritize uniform limits across broad highway networks.

The Heaviest Consumer “Car-Truck” (Pickup/SUV)

If by “car truck” you mean a consumer pickup or SUV, the shift to electrification has pushed curb weights upward due to large battery packs. Below are notable examples among the heaviest passenger-market trucks currently on sale or recently delivered.

• GMC Hummer EV pickup: About 9,063 lb (≈4,111 kg) curb weight, among the heaviest consumer vehicles ever sold in North America.
• Heavy-duty diesel dually pickups (e.g., Ford F-450, Ram 3500): Depending on configuration, curb weights can approach or exceed 8,000 lb (≈3,630 kg).
• Tesla Cybertruck: Depending on configuration, roughly 6,850–7,000 lb (≈3,105–3,175 kg) curb weight.
• Rivian R1T: Generally around 7,000+ lb (≈3,175+ kg), depending on battery and trim.

Among mainstream passenger vehicles, these figures illustrate how premium EV pickups eclipse many conventional heavy-duty trucks in mass, with implications for range, braking, tire wear, and infrastructure.

Why It Matters

Vehicle mass affects road wear, bridge loading, stopping distances, energy consumption, and emissions (or electricity demand). Regulators cap road-legal weights to balance freight efficiency with safety and infrastructure life. In the consumer market, heavier EV pickups deliver performance and range but can raise concerns about tire particulate, braking distances, and compatibility with existing parking structures and lifts.

Summary

The heaviest truck overall is the BelAZ 75710, an off-highway mining giant weighing about 360 tonnes empty and around 810 tonnes fully loaded. On public roads, the heaviest legal truck combinations are Australia’s multi-trailer road trains, which commonly exceed 100 tonnes on designated routes and can go higher under permit. In the consumer space, the GMC Hummer EV pickup, at roughly 9,063 lb curb weight, stands out as one of the heaviest “car-truck” models available.

What is the heaviest legal truck?

Federal law limits the weight of commercial motor vehicles (CMVs) to 80,000 lbs.

What truck is the heaviest?

The heaviest truck in the world is the BelAZ 75710, a massive mining dump truck with a payload capacity of up to 496 tons (450 metric tons) and a total loaded weight of over 810,000 pounds (360 metric tons). Other heavy-duty trucks include the Caterpillar 797F, Liebherr T 284, and the International CXT, though these are significantly smaller than the BelAZ 75710. 
The World’s Heaviest Truck

• BelAZ 75710: This truck, built in Belarus, is engineered for the extreme conditions of open-pit mines and is known for its ability to haul enormous quantities of rock. 
• Massive Scale: When fully loaded, it weighs over 810,000 pounds (360 metric tons), a weight that is incredibly large and dwarfs other vehicles like bulldozers. 
• Power: It features two diesel engines with a combined horsepower of over 4,600 and an advanced electromechanical drivetrain to move its massive weight. 
• Specialized Tires: Its eight enormous tires are designed to support extreme loads and stand approximately 13 feet tall.

What is the heaviest car in the world?

The Rolls-Royce Spectre (6,559 lbs) is a contender for the heaviest car in production, but the heaviest car ever built is the Soviet-era ZIL-41047, an armored limousine weighing 7,352 pounds. 
Current Production Heaviest Cars

• Rolls-Royce Spectre: This electric luxury coupe weighs 6,559 pounds, with nearly 1,543 pounds attributed to its battery pack. 
• BMW XM Red Label: This high-performance SUV weighs 6,162 pounds. 
• Rolls-Royce Cullinan: A large luxury SUV, the Cullinan weighs around 6,069 pounds. 

Heaviest Car Ever Built 

• ZIL-41047: This Soviet-era armored limousine is considered the heaviest car ever made, weighing 7,352 pounds (3,335 kg) and featuring 3 inches of steel armor plating.

Factors Contributing to Weight

• Luxury Features: Luxury vehicles often have heavy sound-insulating materials, double-glazed windows, and extensive use of metal in the cabin. 
• Armor and Protection: The ZIL-41047 was heavily armored, significantly increasing its weight. 
• Powertrain: Large engines and powerful electric powertrains, especially with large battery packs, add significant weight to a vehicle. 

Which SUV is the heaviest?

The 2000-2006 Ford Excursion is often considered one of the heaviest SUVs ever made, with some sources indicating weights over 7,000 pounds, while the 2025 GMC Hummer EV SUV is the heaviest electric SUV, weighing over 9,000 pounds. For current production gasoline vehicles, the 2022 Jeep Grand Wagoneer (6,390 lbs) and the 2025 Cadillac Escalade are among the heaviest.
