Handbrake Turn
The handbrake turn (also known as the bootlegger's turn) is a driving technique used to deliberately slide a car sideways, either for the purpose of quickly negotiating a very tight bend, or for turning around well within the vehicle's own turning diameter. Technique The driver starts by using steering input to transfer weight to the outside tires; the handbrake is then used to lock the rear wheels, thus upsetting the adhesion between the tires and the road surface. With practice, the car can be placed accurately by releasing the handbrake and accelerating the vehicle. The technique is used in some forms of motorsport, for example rallying, autotesting, drifting and motorkhana. Many sports cars, especially UK makes such as MG and Triumph, as late as the early 1970s were offered with a fly-off handbrake option for competition purposes—the button on the end of the lever has to be pressed before the brake will lock on, which is the reverse of the normal arrangement—allowing ...

Motorsport
Motorsport, motorsports or motor sport is a global term used to encompass the group of competitive sporting events which primarily involve the use of motorized vehicles. The terminology can also be used to describe forms of competition of two-wheeled motorised vehicles under the banner of motorcycle racing, and includes off-road racing such as motocross. Four- (or more) wheeled motorsport competition is globally governed by the Fédération Internationale de l'Automobile (FIA); and the Fédération Internationale de Motocyclisme (FIM) governs two-wheeled competition. Likewise, the Union Internationale Motonautique (UIM) governs powerboat racing while the Fédération Aéronautique Internationale (FAI) governs air sports, including aeroplane racing. All vehicles that participate in motorsports must adhere to the regulations that are set out by the respective global governing body. History In 1894, a French newspaper organised a race from Paris to Rouen and back, star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bootleg Turn
{{Unreferenced, date=June 2008 A bootleg turn is a driving maneuver intended to reverse the direction of travel of a forward-moving automobile by 180 degrees in a minimum amount of time while staying within the width of a two-lane road. This maneuver is also known as a smuggler's turn, powerslide, or simply a bootlegger. Technique The turn is performed by putting the vehicle quickly into a lower gear, usually the second gear, and quickly turning the wheel in the direction of the opposite lane. If performed correctly, the vehicle will enter a controlled skid, enter the opposite lane, and turn completely around. In a perfect bootleg turn, the car will be at a complete stop at the end of the maneuver and ready to accelerate and depart in the opposite direction. It is easier to initiate this with some cars by applying a flick of the steering wheel the wrong way initially, before turning it in the direction the driver wants to go. This maneuver (known in racing as a Scandinavian fli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Left-foot Braking
Left-foot braking is the technique of using the left foot to operate the brake pedal in an automobile, leaving the right foot dedicated to the throttle pedal. It contrasts with the practice of using the left foot to operate the clutch pedal, leaving the right foot to share the duties of controlling both brake and gas pedals. At its most basic purpose, left-foot braking can be used to decrease the time spent moving the right foot between the brake and throttle pedals, and can also be used to control load transfer. It is most commonly used in auto racing (simultaneous gas and brake keeps turbo pressure and reduces turbo lag). Racing and rallying Karts, many open-wheelers, and cars that are equipped with automatic transmissions, or semi-automatic transmissions with paddle-shifters (as used in motorsports such as Formula One) have no foot-operated clutch, and allow, or sometimes even require the driver to use their left foot to brake. One common race situation that requires left- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicle Rollover
A rollover 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. Dynamics Vehicle rollovers are divided into two categories: tripped and untripped. Tripped rollovers are caused by forces from an external object, such as a curb or a collision with another vehicle. Untripped rollovers are the result of steering input, speed, and friction with the ground. Trailers that are not roll-coupled (i.e. those that use a trailer coupling rather than a fifth wheel) are more prone to rolling as they do not have the tractor unit or prime mover for additional stability. Untripped rollovers Untripped rollovers occur when cornering forces destabilize the vehicle. As a vehicle rounds a corner, three forces act on it: tire forces (the centripetal force), inertial effects (the centrifugal force), and gravity. The cornering forces from the tire push the vehicle towards the center of the curve. Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-point Turn
The three-point turn (sometimes called a Y-turn, K-turn, or broken U-turn) is the standard method of turning a vehicle around to face the opposite direction in a limited space, using forward and reverse gears. This is typically done when the road is too narrow for a U-turn. This manoeuvre is a common requirement in driving tests. Process The basic manoeuvre consists of driving across the road turning towards the offside curb, reversing across the road to the original nearside curb while turning, and driving forward towards the original offside curb, now the nearside. In a narrow road or with a longer vehicle, more than three legs may be required to achieve a full 180 degree rotation. Naming ''"Three point turn"'' is the formal name in Australia, Canada, New Zealand, and in many regions of the United States. Less common terms are: ''"Y-turn"'', ''"K-turn"'', and ''Broken U-turn'' but in the UK, the official name is ''"Turning in the road (using forward and reverse gears)"'' ...

Boy Racer
Boy racer is a term given to a young person who drives in a fast and aggressive manner; it has become a broader term (often pejorative) for participants in modern custom car culture who tune and modify cars with street racing-style aftermarket cosmetic and performance parts such as body kits, audio systems and exhausts. The culture encompasses a broad range of car types including sport compacts and economy cars typical of the import scene, this is in contrast with the hot rod culture of previous generations. Some car enthusiasts and modifiers feel the term labels them as deviant and anti-social and are keen to distance themselves from the term. Boy racer is a term mostly but not exclusively associated with the UK, in Australia and New Zealand hoon is sometimes preferred. In the US, "Rice boy" or "Ricer" is a derogatory term for the driver or builder of an imported hot rod, or someone who modifies their car in a cheap way to imitate the look of a higher performance vehicle ...

Parallel Parking
250px, Parallel-parked cars in Washington, D.C. 250px, A motorist gets assistance parallel-parking 250px, Parallel parking animation Parallel parking is a method of parking a vehicle parallel to the road, in line with other parked vehicles. Parallel parking usually requires initially driving slightly past the parking space, parallel to the parked vehicle in front of that space, keeping a safe distance, then followed by reversing into that space. Subsequent position adjustment may require the use of forward and reverse gears. Techniques Parallel parking is considered to be one of the most stressful and difficult skills for new drivers to learn. While parallel parking is a required part of most driving tests, several states in the US have dropped it as a requirement. Parallel parking enables the driver to park a vehicle in a smaller space than would be true of forward parking. Driving forward into a parking space on the side of a road is typically not possible unless two or mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stunt
A stunt is an unusual and difficult physical feat or an act requiring a special skill, performed for artistic purposes usually on television, theaters, or cinema. Stunts are a feature of many action films. Before computer generated imagery special effects, these effects were limited to the use of models, false perspective and other in-camera effects, unless the creator could find someone willing to jump from car to car or hang from the edge of a skyscraper: the stunt performer or stunt double. Types of stunt effects Practical effects One of the most-frequently used practical stunts is stage combat. Although contact is normally avoided, many elements of stage combat, such as sword fighting, martial arts, and acrobatics required contact between performers in order to facilitate the creation of a particular effect, such as noise or physical interaction. Stunt performances are highly choreographed and may be rigorously rehearsed for hours, days and sometimes weeks before a pe ...

Centripetal Force
A centripetal force (from Latin ''centrum'', "center" and ''petere'', "to seek") is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path. Isaac Newton described it as "a force by which bodies are drawn or impelled, or in any way tend, towards a point as to a centre". In Newtonian mechanics, gravity provides the centripetal force causing astronomical orbits. One common example involving centripetal force is the case in which a body moves with uniform speed along a circular path. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. The mathematical description was derived in 1659 by the Dutch physicist Christiaan Huygens. Formula The magnitude of the centripetal force on an object of mass ''m'' moving at tangential speed ''v'' along a path with radius of curva ...

Turning Diameter
The turning diameter of a vehicle is the minimum diameter (or "width") of available space required for that vehicle to make a circular turn (i.e. U-turn). The term thus refers to a theoretical minimal circle in which for example an aeroplane, a ground vehicle or a watercraft can be turned around. The terms turning radius and turning circle are sometimes used, but can have different meanings (see the section on Alternative nomenclature below). The Oxford English Dictionary describes turning circle as "the smallest circle within which a ship, motor vehicle, etc., can be turned round completely". On wheeled vehicles with the common type of front wheel steering (i.e. one, two or even four wheels at the front capable of steering), the vehicle's turning diameter is a measure of the space needed to turn the vehicle around while the steering is set to its maximum displacement from the central 'straight ahead' position - i.e. either extreme left or right.
