The world of car weights is filled with terms like curb weight, gross vehicle weight, gross axle weight rating, gross vehicle weight rating, and gross combination weight rating. Grasping these terms aids in comparing vehicles, gauging cargo capacity, maneuvering safely on roads and bridges, evaluating vehicle safety, considering environmental impact, and appraising overall vehicle dynamics.

Let’s examine these terms in detail to better comprehend their importance.

Curb Weight

Kerb weight, also known as curb weight, significantly influences a vehicle’s performance, fuel efficiency, and safety. It refers to the weight of the car, including essential components and necessary operating fluids, but without the weight of passengers, cargo, or luggage. This weight is often used as a base value to calculate other weights, such as gross vehicle weight and gross vehicle weight rating.

Gross Vehicle Weight

Another key term is Gross Vehicle Weight (GVW). The term refers to the combined weight of the vehicle, passengers, cargo, and any additional features. It encompasses the total load the vehicle can safely carry. So, it’s essentially the curb weight plus the weight of everything else in the vehicle. This weight is significant as it can influence the vehicle’s performance, safety, and fuel efficiency.

Also, keep in mind that you can typically find the GVW in the following places:

  • Manufacturer websites
  • Vehicle’s owner’s manual
  • Vehicle registration documents
  • Vehicle Identification Number Plate (VIN Plate)

Gross Axle Weight Rating

Gross axle weight rating (GAWR) is another key term that you need to understand. It specifies the maximum load that a single axle system can safely carry, as determined by the vehicle manufacturer. This value is important for safety, especially when carrying heavy loads or towing.

Gross Vehicle Weight Rating

Finally, there’s the Gross Vehicle Weight Rating (GVWR). This term refers to the maximum total weight of the vehicle, including all passengers, cargo, and the vehicle itself. Understanding the GVWR is vital, especially when towing, as it keeps the vehicle within the maximum allowable weight limit, preventing vehicle damage, and reducing risks to the driver and others on the road.

Factors Influencing Car Weight

Having familiarized ourselves with key car weight terms, let’s investigate the factors that influence car weight. Cars differ in weight due to variations in:

  • Sizes
  • Materials used
  • Production processes
  • Intended purpose

The adoption of safety equipment and luxury amenities has also led to an increase in the average weight of vehicles over time.

We will examine how engine types and extra components can considerably affect a car’s weight.

Engine Type

The type of engine a vehicle has can significantly influence its vehicle’s weight. For instance, electric vehicles generally weigh more than similar-sized vehicles with gasoline or diesel engines due to the weight of their batteries.

For example, a subcompact electric vehicle like the Chevrolet Bolt EV, which is one of the popular electric cars, can weigh about 1,000 to 1,500 pounds more than a comparable gasoline vehicle.

Additional Components

Added features like all-wheel drive, safety equipment, and luxury amenities can also increase the overall vehicle weight. For instance, compact crossovers and SUVs typically exceed the weight of midsize sedans, often due to their larger size and optional features like all-wheel drive.

Average Car Weights by Category

After discussing the factors that influence car weight, we should examine the average weights of various car categories. This will give us a better understanding of how much various types of cars typically weigh.

We’ll begin with compact cars and then proceed to larger categories like SUVs and passenger cars.

Compact Cars

Compact cars are known for their small size, making them lighter than other car categories. The average weight of compact cars starts around 1,100 kilograms and can go up to approximately 1,400 kilograms. So, if you own a compact car, chances are it weighs somewhere around this range.

Sport Utility Vehicles (SUVs)

Sport Utility Vehicles (SUVs), on the other hand, are much heavier due to their larger size and additional features. The average weight of a large SUV is typically around 2,500 to 2,800 kilograms.

For example, the Cadillac Escalade ESV, a full-size SUV, weighs approximately 2,803 kilograms.

Passenger Cars

Passenger cars, which are designed to carry multiple passengers, have an average weight of approximately 1,850 kilograms. However, this weight can vary based on the car’s size, type, and additional features.

For instance, large luxury cars typically have an average weight of approximately 1,911 kilograms, which is important to consider when discussing car weigh.

How to Determine Your Car’s Weight

Being aware of your car’s weight can be vital for several reasons, including ensuring safe and efficient operation, complying with legal weight restrictions, and comprehending its impact on performance and fuel efficiency. The weight of your specific vehicle can usually be found in the vehicle manual or on a sticker in the driver’s side door jamb. But there are also other ways to determine your car’s weight, including using manufacturer information, vehicle registration details, and professional weighing services.

Manufacturer Information

Manufacturer information is a reliable source for finding car weight details. Vehicle manufacturers frequently list weight information on their websites, typically in the ‘Specifications’ section. A vehicle’s VIN can also be used on automotive websites to access detailed specifications, including weight.

Vehicle Registration Details

Vehicle registration documents often list the weight of a car. These documents are an official record issued by the government, making them a trustworthy source for accurate vehicle weight information.

Professional Weighing Services

Professional weighing services offer another method to accurately measure a vehicle’s weight. These services use calibrated scales and provide thorough reporting, ensuring precise measurements. However, the use of such services comes with an annual maintenance cost, which can range from $1,000 to $3,000, depending on the requirements and type of weighing device.

Effects of Car Weight on Performance and Safety

Car weight is not just a number; it has significant implications for a car’s performance, fuel efficiency, and safety. For instance, a heavier car often offers better protection in a collision but may have higher fuel consumption and slower acceleration. These effects can vary based on the car’s weight and other factors.


In terms of performance, car weight has a significant part to play. Lighter vehicles tend to accelerate faster than heavier ones due to less mass to propel. However, a car’s weight can also affect its handling, especially during dynamic maneuvers like cornering or braking.

For instance, during cornering, weight shifts to the outside tires, which can increase grip but may also lead to oversteer or understeer, impacting handling safety.

Fuel Efficiency

Car weight considerably affects fuel efficiency as well. There is a negative correlation between a car’s weight and its miles per gallon (MPG), meaning fuel efficiency tends to decrease as vehicle weight increases.

For example, heavier cars like SUVs and trucks consume more fuel than smaller, lighter cars.


Safety is another aspect significantly impacted by car weight. Larger and heavier vehicles offer better protection in crashes due to their ability to absorb more energy and provide a longer distance from the front of the vehicle to the occupant compartment. However, in collisions between vehicles of different weights, the heavier vehicle will push the lighter one backward, resulting in less force on the occupants of the heavier vehicle and more on those in the lighter vehicle.

Car Weight Limitations and Restrictions

While knowing car weight is vital, being cognizant of car weight limitations and restrictions is equally significant. These limitations, set by federal and state regulations, dictate the maximum weight that different cars and roads can handle.

Maximum Weight for Different Cars

The maximum weight for cars varies based on vehicle type and category. For instance, the Federal Bridge Formula governs the maximum weight a vehicle can carry on the Interstate Highway System and takes into account the number of axles and spacing between them.

States also have the authority to set their own axle weight limits, considering their infrastructure and traffic.

Road Weight Restrictions

Road weight restrictions, determined by states, can also vary depending on infrastructure and traffic considerations. For instance, the weight limit on most U.S. state highways is approximately 80,000 pounds, aligning with the interstate system limit.


In summary, understanding car weight is more than just knowing how much your vehicle weighs. It’s about understanding the intricacies of different car weight measurements, the factors influencing car weight, and its implications for performance, fuel efficiency, and safety. As we’ve seen, car weight can significantly impact your driving experience and the overall functionality of your vehicle.
