Kerb Weight vs Gross Vehicle Weight: What's the Difference?

This guide draws on V3Cars' Kerb Weight Vs Gross Vehicle Weight: What's The Difference? coverage.

Open any car's spec sheet or owner's manual and you'll typically find two different weight figures listed — kerb weight and gross vehicle weight (GVW). They're often confused, but they measure genuinely different things, and understanding the gap between them tells you exactly how much your car can safely carry.

What Is Kerb Weight?

Kerb weight is the weight of a vehicle in its standard operating condition — essentially, how heavy the car is before anyone gets in or any luggage is loaded. It includes:

  • The vehicle itself with all standard factory equipment
  • A full tank of fuel
  • All essential operating fluids (engine oil, coolant, brake fluid, transmission fluid)

It does not include the driver, passengers, luggage or any aftermarket accessories. As an example: the 2026 Maruti Suzuki Brezza turbo-petrol has a kerb weight of 1,150 kg — that's how much the car weighs sitting empty, fuelled and ready to drive.

What Is Gross Vehicle Weight (GVW)?

Gross Vehicle Weight (GVW), also called Gross Weight, is the maximum permitted weight of the vehicle when fully loaded. It includes:

  • The kerb weight
  • All occupants (driver and passengers)
  • All luggage and cargo

Manufacturers specify a maximum GVW to ensure the car remains safe to operate within the design limits of its suspension, tyres, brakes and chassis. Exceeding it isn't just a performance concern — it's a genuine safety and structural risk. The GVW figure can be found in the owner's manual or on the vehicle's registration certificate (RC).

How to Calculate Payload Capacity

The relationship between the two figures gives you a genuinely useful number: payload capacity — how much weight (people plus cargo) your car can safely carry.

Payload Capacity = Gross Vehicle Weight − Kerb Weight

Using the 2026 Brezza turbo-petrol as a real example: with a kerb weight of 1,150 kg and a gross vehicle weight of 1,600 kg (as confirmed by dealers), the payload capacity works out to 450 kg. That 450 kg figure covers the driver, all passengers, and any luggage combined — a useful number to keep in mind before loading up for a long family trip or a heavily-packed road trip.

Why This Distinction Actually Matters

  • Vehicle comparisons: Kerb weight is the standard figure used to compare how heavy different cars are from the factory — useful for understanding fuel efficiency and handling characteristics, since lighter cars generally accelerate quicker and sip less fuel.
  • Safe loading: GVW and payload capacity tell you the real-world limit on how much you can safely pack into a car — important for anyone regularly carrying a full complement of passengers plus luggage, or towing.
  • Legal compliance: Exceeding a vehicle's GVW isn't just risky — in many cases it's a legal violation, and it can also affect insurance claims in the event of an accident if the vehicle was demonstrably overloaded at the time.
  • Structural safety: Suspension, brakes and tyres are all engineered around the GVW limit. Consistently overloading a car accelerates wear on all three and can compromise handling and braking performance, particularly in emergency situations.

Related Weight Terms You Might Encounter

  • Unladen weight / minimum kerb weight: The vehicle's weight with all fluids but without a full fuel tank
  • Dry weight: The vehicle's weight without any fuel or fluids at all — the lightest possible figure, rarely used for real-world comparison
  • Gross Vehicle Weight Rating (GVWR): Functionally the same concept as GVW — the manufacturer-specified maximum safe operating weight, usually found on a plate inside the driver's door frame or in the owner's manual

Final Word

Kerb weight tells you how heavy your car is empty; gross vehicle weight tells you the absolute ceiling on how much it can safely carry once loaded. The gap between the two — the payload capacity — is the number worth actually remembering, especially if you regularly drive with a full car of passengers and luggage. Check both figures in your owner's manual before a long trip, and treat the GVW limit as a hard ceiling rather than a rough guideline.

Weight figures vary by variant, engine and transmission choice. Always confirm the exact kerb weight and GVW for your specific vehicle variant in the owner's manual or registration certificate before loading it to capacity.
