Autobesity, also known as car bloat and truck bloat, is the trend, beginning in about the 1990s, [3] of cars increasing in average size and weight. [4] [5] The average weight of cars sold in Europe increased by 21% between 2001 and 2022. [6] In the United States, SUVs and pickup trucks comprised more than 75% of new sales in 2024 compared to 38% in 2009. [7]
Among the consequences of increased car weight and size are:
An individual driver may choose a large car for personal safety, though it threatens other road users. This in turn pushes others to choose large cars, a vicious circle. A US National Safety Council expert described autobesity as an "arms race". [16]
Even though this is a decisive factor that some buyers do take into account, even the ones that don't actively search for larger vehicles are affected due to the increase in the number of safety features: from airbags to crumple zones. These require much more space in the vehicle, even adding areas of apparently empty space just so that the bodywork can move in case of an accident. [17]
A truck or lorry is a motor vehicle designed to transport freight, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "tractor".
The vast majority of passenger travel in the United States occurs by automobile for shorter distances and airplane or railroad for longer distances. Most cargo in the U.S. is transported by, in descending order, railroad, truck, pipeline, or boat; air shipping is typically used only for perishables and premium express shipments. Transportation is the largest source of greenhouse gas emissions in the United States.
A sport utility vehicle (SUV) is a car classification that combines elements of road-going passenger cars with features from off-road vehicles, such as raised ground clearance and four-wheel drive.
A pickup truck or pickup is a light or medium duty truck that has an enclosed cabin, and a back end made up of a cargo bed that is enclosed by three low walls with no roof. In Australia and New Zealand, both pickups and coupé utilities are called utes, short for utility vehicle. In South Africa, people of all language groups use the term bakkie; a diminutive of Afrikaans: bak, meaning bowl or container.
Automotive safety is the study and practice of automotive design, construction, equipment and regulation to minimize the occurrence and consequences of traffic collisions involving motor vehicles. Road traffic safety more broadly includes roadway design.
Governments and private organizations have developed car classification schemes that are used for various purposes including regulation, description, and categorization of cars.
Corporate average fuel economy (CAFE) standards are regulations in the United States, first enacted by the United States Congress in 1975, after the 1973–74 Arab Oil Embargo, to improve the average fuel economy of cars and light trucks produced for sale in the United States. More recently, efficiency standards were developed and implemented for heavy-duty pickup trucks and commercial medium-duty and heavy-duty vehicles. CAFE neither directly offers incentives for customers to choose fuel efficient vehicles nor directly affects fuel prices. Rather, it attempts to accomplish the goals indirectly, by making it more expensive for automakers to build inefficient vehicles by introducing penalties.
Light truck or light-duty truck is a US classification for vehicles with a gross vehicle weight up to 8,500 pounds (3,860 kg) and a payload capacity up to 4,000 pounds (1,814 kg). Similar goods vehicle classes in the European Union, Canada, Australia, and New Zealand are termed light commercial vehicles and are limited to a gross vehicle weight of up to 3,500 kg.
Crash incompatibility, crash compatibility, vehicle incompatibility, and vehicle compatibility are terms in the automobile crash testing industry. They refer to the tendency of some vehicles to inflict more damage on another vehicle in two-car crashes. Vehicle incompatibility is said to lead to more dangerous, fatal crashes, while compatibility can prevent injury in otherwise comparable crashes.
A bumper is a structure attached to or integrated with the front and rear ends of a motor vehicle, to absorb impact in a minor collision, ideally minimizing repair costs. Stiff metal bumpers appeared on automobiles as early as 1904 that had a mainly ornamental function. Numerous developments, improvements in materials and technologies, as well as greater focus on functionality for protecting vehicle components and improving safety have changed bumpers over the years. Bumpers ideally minimize height mismatches between vehicles and protect pedestrians from injury. Regulatory measures have been enacted to reduce vehicle repair costs and, more recently, impact on pedestrians.
A crossover, crossover SUV, or crossover utility vehicle (CUV) is a type of automobile with an increased ride height that is built on unibody chassis construction shared with passenger cars, as opposed to traditional sport utility vehicles (SUVs), which are built on a body-on-frame chassis construction similar to pickup trucks.
The Volvo XC90 is a mid-size luxury SUV manufactured and marketed by Volvo Cars since 2002 and now in its second generation.
Vehicle size classes are series of ratings assigned to different segments of automotive vehicles for the purposes of vehicle emissions control and fuel economy calculation. Various methods are used to classify vehicles; in North America, passenger vehicles are classified by total interior capacity while trucks are classified by gross vehicle weight rating (GVWR). Vehicle segments in the European Union use linear measurements to describe size. Asian vehicle classifications are a combination of dimensions and engine displacement.
A rollover or overturn is a type of vehicle crash in which a vehicle tips over onto its side or roof. Rollovers have a higher fatality rate than other types of vehicle collisions.
The Insurance Institute for Highway Safety and Highway Loss Data Institute (IIHS-HLDI) is an American nonprofit organization. It was established in 1959, and it is noted for its safety reviews of vehicles in various simulated traffic situations, including the effectiveness of a vehicle's structural integrity and safety systems during a collision, in addition to examining improvement on such elements.
A bullbar or push bumper is a device installed on the front of a vehicle to protect its front from collisions, whether an accidental collision with a large animal in rural roads, or an intentional collision by police with another vehicle. They vary considerably in size and form, and are normally composed of welded steel or aluminium tubing, or, more recently, moulded polycarbonate and polyethylene materials. The "bull" in the name refers to cattle, which in rural areas sometimes roam onto rural roads and highways.
Sport utility vehicles (SUVs) have been criticized for a variety of environmental and automotive safety reasons. The rise in production and marketing of SUVs in the 2010s and 2020s by auto manufacturers has resulted in over 80% of all new car sales in the United States being SUVs or light trucks by October 2021. This rise in SUV sales has also spilled over into the United Kingdom and the European Union. It has generated calls from car safety advocates to downsize in favor of models such as sedans, wagons, and compacts.
A car, or an automobile, is a motor vehicle with wheels. Most definitions of cars state that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people rather than cargo. There are around one billion cars in use worldwide.
The Volvo XC40 is a subcompact luxury crossover SUV (C-segment) manufactured by Volvo Cars. It was unveiled on 21 September 2017 as the smallest SUV model from Volvo, below the XC60. Orders started in September 2017, and manufacturing began in November 2017.
The GMC Hummer EV is a line of battery electric heavy-duty vehicles produced by General Motors since 2021, and sold under the GMC marque. The Hummer EV is offered in two variants: a pickup truck and a sport utility vehicle (SUV), unveiled in October 2020 and April 2021 respectively.
