Four-wheel drive, 4WD, 4x4 ("four by four"), or AWD ("all wheel drive") is a four-wheeled vehicle A vehicle is a mechanical means of conveyance, a carriage or transport. Most often they are manufactured (e.g. bicycles, cars, motorcycles, trains, ships, boats, and aircraft), although some other means of transport which are not made by humans also may be called vehicles; examples include icebergs and floating tree trunks with a drivetrain In a motor vehicle, the term powertrain or powerplant refers to the group of components that generate power and deliver it to the road surface, water, or air. This includes the engine, transmission, driveshafts, differentials, and the final drive . Sometimes "powertrain" is used to refer to simply the engine and transmission, including that allows all four wheels A wheel is a circular device that is capable of rotating on its axis, facilitating movement or transportation whilst supporting a load , or performing labour in machines. Common examples are found in transport applications. A wheel, together with an axle overcomes friction by facilitating motion by rolling. In order for wheels to rotate, a moment to receive torque from the engine An engine is a mechanical device that produces some form of output from a given input. When the purpose of an engine is to produce mechanical power from a fuel source it is referred to as a prime mover; alternatively, a motor is a device which produces mechanical power from other forms of energy . An automobile makes use of several motors to start simultaneously. While many people associate the term with off-road vehicles An off-road vehicle is considered to be any type of vehicle which is capable of driving on and off paved or gravel surface. It is generally characterized by having large tires with deep, open treads and a flexible suspension, or even caterpillar tracks.[citation needed] Other vehicles that do not travel public streets or highways are generally and Sport utility vehicles A sport utility vehicle is a generic marketing term for a vehicle similar to a station wagon, but built on a light-truck chassis. Usually equipped with four-wheel drive for on or off-road ability, some SUVs include the towing capacity of a pickup truck with the passenger-carrying space of a minivan. Since SUVs are considered light trucks and often, powering all four wheels provides better control in normal road cars on many surfaces, and is an important part of rally racing Rallying is a form of motor competition that takes place on public or private roads with modified production or specially built road-legal cars. This motorsport is distinguished by running not on a circuit, but instead in a point-to-point format in which participants and their co-drivers drive between set control points , leaving at regular,
In abbreviations such as 4x4, the first figure is normally taken as the total number of wheels and the second is normally taken as the number of powered wheels (the numbers are actually axle-ends to allow for more than one wheel on each end of an axle). 4x2 means a four-wheel vehicle in which engine power is transmitted to only two axle-ends: the front two in front-wheel drive Front-wheel drive is a form of engine/transmission layout used in motor vehicles, where the engine drives the front wheels only. Most modern front-wheel drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel drive and four-wheel drive vehicles or the rear two in rear-wheel drive In automotive design layout specifies where on the car the engine and drive wheels are found.[1]
