Vehicle size classes are a way of classifying cars. The common North American parlance is word-based, while English-speaking European writers also use words to describe car sizes. In parts of Asia, segment letters are sometimes used.

North America[edit]

USA[edit]

American government defined size of Federal Regulations, Title 40—Protection of Environment, Section 600.315-82 Classes of comparable automobiles. Passenger car classes are defined based on interior volume index or seating capacity, except the ones classified as special vehicle. A two seater is classified as a car with no more than two designated seating positions. Others as follows:

ClassMinicompact carSubcompact carCompact carMidsize carLarge car
Interior combined passenger and cargo volume index in cubic feet (liters)under 85 (2407)85–99.9 (2407–2831)100–109.9 (2832–3114)110–119.9 (3115–3397)120 (3398) or over

Interior volume index in cubic feet (liters)under 130 (3681)130–160 (3681–4531)over 160 (4531)

Nonpassenger automobiles are defined as small pickup trucks, standard pickup trucks, vans, and special purpose vehicles. Pickup trucks is separated from car line based on gross vehicle weight rating (GVWR). For pickup truck car lines with more than one GVWR (gross vehicle weight rating), the GVWR of the pickup truck car line is the arithmetic average of all distinct GVWR's less than or equal to 8,500 pounds available for that car line.

ClassSmall pickup truckStandard pickup truckVan
GVWR in pound (kg)under 4500 (2041)4500–8500 (2041–3856)undefined

Special purpose vehicle is defined as automobile with GVWR less than or equal to 8,500 pounds which possess special features that are more appropriately classified separately from typical automobiles or which do not meet the definitions of above mentioned classes.

Interior volume index is calculated differently for different vehicle classes:

All dimensions and volumes shall be determined from the base vehicles of each body style in each car line, and do not include optional equipment.

Front seat volume is calculated as product of:

Rear seat volume is calculated for vehicles within a rear seat equipped with rear seat belts (as required by DOT), as product of:

For passenger automobiles with no rear seat or with a rear seat but no rear seat belts, the area to the rear of the front seat shall be included in the determination of usable luggage capacity.

Cargo volume index is calculated as follows:

Canada[edit]

Cars are divided into six classes based on interior volume. An interior volume index is calculated from the combined passenger and trunk or cargo space. Pickup trucks, special purpose vehicles and vans are segmented in their own respective classes.

The above definitions of vehicle classes are not defined in Canadian regulations, but by Fuel Consumption Guide published by Natural Resources Canada.

Other vehicle classes are listed in On-Road Vehicle and Engine Emission Regulations (SOR/2003-2), officially published in Canada Gazette Part 2, Vol. 137 No. 1:

Classlight light-duty trucklight-duty truckheavy light-duty truckheavy-duty vehiclemedium-duty passenger vehicle

In case of light-duty trucks, all 3 conditions must be met, otherwise it is classified as heavy-duty vehicle. In addition, light-duty must also be:

Medium-duty passenger vehicle is classified as a heavy-duty vehicle that is designed primarily for the transportation of persons but does not include any vehicle that

Motorcycle is classified as an on-road vehicle with a headlight, taillight and stoplight that has two or three wheels and a curb weight of 793 kg or less, but does not include a vehicle that has an engine displacement of less than 50 cc, or that, with an 80 kg (176 pound) driver:

Europe[edit]

Vehicle segments in Europe do not have formal characterization or regulations. Models segments tend to be based on comparison to well-known brand models. For example, a car such as the Volkswagen Golf might be described as being in the Ford Focus size class, or vice versa. The VW Polo is smaller, so it belongs one segment below the Golf, while the bigger Passat is one segment above.

This is a table listing several different methods of car classification.

EuroNCAP applies a standard safety test to all new cars, the results are listed in separate categories to allow prospective vehicle purchasers to compare models of a similar size and shape:

Asia[edit]

China[edit]

Vehicle size categories for passenger vehicles for the China NCAP program as defined by the China Automotive Technology and Research Center (CATARC) may appear similar to the European system, but are closer to the Japanese in application.

Japan[edit]

Sections of this article are translated from Japanese Wikipedia.

Vehicle size classes in Japan are rather simple compared to other regions. The classifications were established under the Japanese Government's Road Vehicle Act of 1951.[5][6] There are just three different classes defined by regulations. The law doesn't have revised classifications for roadsters, minivans, station wagons, SUVs, MPVs, or Crossovers. These standards of classification are enforced on all vehicles within the jurisdiction of Japan, and no special consideration is made for the vehicles origination of manufacture. The Japanese law regulates all vehicles that do not travel on railroads, or are not powered by physically contacting overhead power lines. The law regulates vehicles that are powered by an autonomous power source.

Motorcycles also have classification definitions based on engine size:

All vehicles with an engine displacement over 250cc are required to undergo an inspection (called "Shaken" in Japan). The tax charged for the size and engine displacement of the vehicle is paid when the inspection is successful. This is separate from the road tax paid yearly.
