83-676: Aussie Racing Cars (ARC), currently known as the Battery World Aussie Racing Cars under sponsorship, is an Australian motor racing category. ARC is a motorcycle powered silhouette racing car class created by former touring car racing driver Phil Ward and influenced by the American Legends category. Aussie Racing Cars was developed as a Major National Category supporting the V8 Supercars under an exclusive Category Management Agreement (CMA) with

166-477: A V8 Supercar . They feature fully adjustable suspension geometry, performance brakes and controlled competition tyres that produce high grip levels. All cars are hand built in the ARC facility and supplied ready to race. The cockpit layout is purpose built and fitted with a five-point racing harness. The steering requires only one turn lock-to-lock and minimal steering movement during racing. The sequential gear lever

249-490: A rack and pinion mechanism that converts several turns of the steering wheel into a large linear displacement. Alternatively, it may use a recirculating ball system. The mechanism may be power-assisted , usually by hydraulic or electrical means. The use of a variable rack (still using a normal pinion) was invented by Arthur Ernest Bishop in the 1970s, so as to improve vehicle response and aim to allow for more comfortable steering, especially at high speeds. He also created

332-584: A National Series. Over its 20-year history the category has supported the biggest motorsports events in Australia including the Adelaide 500 , Gold Coast Indy 300 , F1 Australian Grand Prix and Bathurst 1000 . The Hampton Downs round of the 2016 season hosted the inaugural Trans-Tasman Women's Challenge. Charlotte Poynting was chosen to represent Team Australian, and was up against Alyssa Clapperton of Team New Zealand. In Race 3 Poynting, who started 9th on

415-414: A centering cam which pushed the steering rack and wheel back to the straight-ahead position. The centering force increased with speed, requiring more effort to turn the wheel at greater speeds. Modern speed-sensitive power steering systems reduce the mechanical or electrical assistance as the vehicle speed increases, giving a more direct feel. This feature is gradually becoming more common. For example, it

498-433: A distance of eight miles. It was won by the locomotive of Isaac Watt Boulton , one of six he said he had run over the years, perhaps driven by his 22-year-old son, James W. The race was against Daniel Adamson's carriage, likely the one made for Mr. Schmidt and perhaps driven by Mr. Schmidt himself. The reports do not indicate who was driving, since both were violating the red-flag law then fully in force. Boulton's carriage

581-407: A driver a greater mechanical advantage, resulting in its use on larger, heavier vehicles, while the rack and pinion would originally be limited to smaller and lighter ones; due to the almost universal adoption of power steering , however, this is no longer considered an important advantage, leading to the increasing use of rack and pinion mechanisms on newer cars. The recirculating ball design also has

664-593: A high-speed test, car handling manoeuvres can be tested such as precision drifting , donuts, handbrake turns, reversing and so on. Other disciplines of automobile sport include: The international motorcycle sport governing body recognised by the International Olympic Committee is the Fédération Internationale de Motocyclisme (FIM). Disciplines include: The international powerboating governing body recognised by

747-591: A hill, at private and closed roadways where higher speeds and distances can be reached than at an autotesting course for example. Time attack are terms used by series that run sprints at racing circuits where competitors try to set the quickest lap time rather than racing head-to-head with others. Time trials are run by the Sports Car Club of America , amongst others. Rallysprints are mainly sanctioned and held in continental Europe. Ultimately, they are similar to other time trial sprints but originate from

830-477: A large wheelbase, while at higher speeds both front and rear wheels turn alike (electronically controlled), so that the vehicle may change position with less yaw and improved build-up of the lateral acceleration, enhancing straight-line stability. The "snaking effect" experienced during motorway drives while towing a travel trailer is thus largely nullified. Four-wheel steering found its most widespread use in monster trucks , where maneuverability in small arenas

913-404: A low cost press forging process to manufacture the racks, eliminating the need to machine the gear teeth. Other arrangements are sometimes found on different types of vehicles; for example, a tiller or rear-wheel steering. Tracked vehicles such as bulldozers and tanks usually employ differential steering , where the tracks are made to move at different speeds or in opposite directions, using

996-582: A perceptible lash, or "dead spot" on center, where a minute turn of the steering wheel in either direction does not move the steering apparatus; this is easily adjustable via a screw on the end of the steering box to account for wear, but it cannot be eliminated because it will produce excessive internal forces at other positions and the mechanism will wear very rapidly. This design is still in use in trucks and other large vehicles, where rapidity of steering and direct feel are less important than robustness, maintainability, and mechanical advantage. The worm and sector

1079-452: A race is between competitors running head-to-head, in its International Sporting Code, the FIA defines racing as two or more cars competing on the same course simultaneously. Circuit racing takes place on sealed-surface courses at permanent autodromes or on temporary street circuits . Competitors race over a set number of laps of the circuit with the winner being the first to finish, or for

1162-447: A rudder, thrust vectoring , or both. Small sport hovercraft have similar rudders, but steer mostly by the pilot shifting their weight from side to side and unbalancing the more powerful lift forces beneath the skirt. Jet packs and flying platforms are steered by thrust vectoring only. Helicopter flight controls are steered by cyclic control, changing the thrust vector of the main rotor(s), and by anti-torque control, usually provided by

1245-464: A sealed surface such as asphalt or concrete. Notable off-road races on open terrain include the Baja 1000 desert race, organised by SCORE International . The FIA authorise Extreme E , an electric off-road series whose organisers have announced a hydrogen fuel series, Extreme H, to begin in 2025. Examples of off-road racing disciplines and series include: Drag racing is an acceleration contest from

1328-436: A set length of time with the winner having completed the highest number of laps, with others classified subsequently. Circuit racing replaced point-to-point (city-to-city) racing early in the history of motorsport, for both spectator appeal and as safety concerns brought in regulation of the sport, forcing organisers to use closed, marshalled and policed circuits on closed public roads. Aspendale Racecourse in Australia in 1906

1411-412: A special type of active four-wheel steering. It operates by steering all wheels in the same direction and at the same angle. Crab steering is used when the vehicle needs to proceed in a straight line but at an angle: when changing lanes on a highway at speed, when moving loads with a reach truck, or during filming with a camera dolly. Rear wheel steering can also be used when the rear wheels may not follow

1494-399: A standing start along a short and straight course. Vehicles of various types can compete, usually between two vehicles. Winners can be the first to finish of competing pairs or by setting the fastest time, and competitions may have heats and/or series of runs. Kart racing is a form of circuit racing using very small and low vehicles not considered as automobiles known as go-karts. It is one of

1577-413: A steering mechanism called a rack and pinion . The steering wheel turns a pinion gear, which moves a rack back and forth to steer the wheels. This mechanism converts the circular motion of the steering wheel to linear motion , which is applied to the wheels of the car via tie rods and a steering knuckle . Rack and pinion steering has several advantages, such as a direct steering "feel". This means that

1660-431: A tail rotor. A conventional automotive steering arrangement allows a driver to control the direction of the vehicle by turning the direction of the front wheels using a hand–operated steering wheel positioned in front of the driver. The steering wheel is attached to a steering column , which is linked to rods, pivots and gears that allow the driver to change the direction of the front wheels. The mechanism may include

1743-432: A turn; although the rudder can also be used to turn the aircraft, it is usually used to minimize adverse yaw , rather than as a means to directly cause the turn. On the ground, aircraft are generally steered at low speeds by turning the nosewheel or tailwheel (using a tiller or the rudder pedals) or through differential braking, and by the rudder at high speeds. Missiles, airships and large hovercraft are usually steered by

1826-649: A version of this electronic four-wheel steering system on the Mazda 626 and MX6 in 1988. The first rally vehicle to use the technology was the Peugeot 405 Turbo 16 , which debuted at the 1988 Pikes Peak International Hill Climb. Previously, Honda had mechanical four-wheel steering as an option in their 1987–2001 Prelude and Honda Ascot models (1989–1996) later upgrading to electronically controlled. General Motors offered Delphi's Quadrasteer in their Silverado/Sierra and Suburban/Yukon. Due to low demand, GM discontinued

1909-428: A vessel can steer the ship only when water is passing over it. Hence, when a ship is not moving relative to the water it is in or cannot move its rudder, it does not respond to the helm and is said to have lost steerage . The motion of a ship through the water is known as making way . Boats on rivers must always be under propulsion, even when traveling downstream, in order to steer, requiring sufficient water to pass over

1992-465: Is a designed caricature of its full-size counterpart featuring opening doors, boot and lift off front section. Powered by a 1.3L 125 bhp (93 kW) twin cam 16 valve engine sourced second-hand from used Yamaha FJR1300 motorcycles that revs to 11500 rpm. The 515 kg all up weight provides a high power-to-weight ratio that allows the car to reach speeds in excess of 200 km/h. Lap times achieved at Oran Park Raceway are within six seconds of

2075-453: Is a form of motorsport where drivers intentionally lose rolling traction in corners through oversteering but maintain momentum with effective throttle control, clutch use and corrective steering. In competition a panel of judges award marks on artistry and car control through the corner or series of corners. Competitions often feature pairs of cars driving together where a lead car and a chase car go head-to-head, with only one car going through to

2158-405: Is also possible. A Hydraulic Power Steering (HPS) uses hydraulic pressure supplied by an engine-driven pump to assist the motion of turning the steering wheel. Electric Power Steering (EPS) is more efficient than hydraulic power-steering, since the electric power-steering motor only needs to provide assistance when the steering wheel is turned, whereas the hydraulic pump must run constantly. In EPS,

2241-498: Is called a series, and a grouping of competitions often forms the basis of a championship , cup or trophy . Not all nations have a sporting authority affiliated with the FIA, some disciplines may not fall within the FIA's remit of control, or organisations may choose to ignore the claim of the authority of others. Examples include banger racing and stock car racing in the United Kingdom which are claimed by both

2324-642: Is close to the steering wheel and the carbon fibre dash displays the necessary instrumentation. The chassis design incorporates simplicity in suspension adjustment to cater for all drivers' preferences including castor/camber, sway bar, roll centre and ride height etc. Brakes have front to rear bias adjustment. Motor racing Different manifestations of motorsport with their own objectives and specific rules are called disciplines. Examples include circuit racing , rallying and trials . Governing bodies, also called sanctioning bodies, often have general rules for each discipline, but allow supplementary rules to define

2407-424: Is critical, and it is also popular in large farm vehicles and trucks. Some of the modern European Intercity buses also utilize four-wheel steering to assist maneuverability in bus terminals, and also to improve road stability. Mazda were pioneers in applying four-wheel steering to automobiles, showing it on their 1984 Mazda MX-02 concept car, where the rear wheels counter-steered at low speeds. Mazda proceeded to offer

2490-431: Is normally achieved by changing the rates of the rubber bushings in the suspension. Some suspensions typically have compliance oversteer due to geometry, such as Hotchkiss live axles , semi-trailing arm IRS, and rear twist beams, but may be mitigated by revisions to the pivot points of the leaf spring or trailing arm, or additional suspension links, or complex internal geometry of the bushings. Passive rear-wheel steering

2573-415: Is not a new concept, as it has been in use for many years, although not always recognized as such. Articulated steering is a system by which a vehicle is split into front and rear halves which are connected by a vertical hinge. The front and rear halves are connected with one or more hydraulic cylinders that change the angle between the halves, including the front and rear axles and wheels, thus steering

2656-417: Is not suitable for turns. The angle the wheels make in the vertical plane, known as camber angle , also influences steering dynamics as do the tires. Steering wheel turning is often measured in terms of number of full 360-degree turns to go lock-to-lock . This is when the steering input mechanism is restrained at its mechanical limit from the full right-turn stop to the left-turn stop. Many modern cars have

2739-402: Is the control of the direction of motion or the components that enable its control. Steering is achieved through various arrangements, among them ailerons for airplanes, rudders for boats, cylic tilting of rotors for helicopters, and many more. Aircraft flight control systems are normally steered when airborne by the use of ailerons , spoileron , or both to bank the aircraft into

2822-619: The International Olympic Committee is the Union Internationale Motonautique (UIM). The organisation's origins date back to 1922. The international air sports governing body recognised by the International Olympic Committee is the Fédération Aéronautique Internationale (FAI). The FAI also governs non-powered air sport such as gliding and ballooning, however its motorised sports include: Lock-to-lock Steering

2905-548: The ThrustSSC . In cars, rear-wheel steering tends to be unstable because, in turns, the steering geometry changes, hence decreasing the turn radius (oversteer), rather than increasing it (understeer). Rear-wheel steering is meant for slower vehicles that need high-maneuverability in tight spaces, e.g. fork lifts. For heavy haulage or for increased maneuverability, some semi-trailers are fitted with rear-wheel steering, controlled electro-hydraulically. The wheels on all or some of

2988-694: The United States , dirt track racing became popular. After World War II , the Grand Prix circuit became more formally organised. In the United States, stock car racing and drag racing became firmly established. The Fédération Internationale de l'Automobile (FIA), formed in 1904, is the oldest and most prominent international governing body. It claims to be the sole international motor sporting authority for automobiles and other land vehicles with four or more wheels, whilst acknowledging

3071-457: The bushings to correct this tendency and steer the wheels slightly to the inside of the corner. This improves the stability of the car through the turn. This effect is called compliance understeer ; it, or its opposite, is present on all suspensions. Typical methods of achieving compliance understeer are to use a Watt's link on a live rear axle, or the use of toe control bushings on a twist beam suspension . On an independent rear suspension it

3154-418: The clutch and brakes, to achieve a change of direction. Common steering system components include: The basic aim of steering is to ensure that the wheels are pointing in the desired direction to move the vehicle as required. This is typically achieved by a series of linkages, rods, pivots, and gears. One of the fundamental concepts is that of caster angle . Each wheel is steered with a pivot point ahead of

3237-473: The pitman arm , which is connected to the steering linkage and thus steers the wheels. The recirculating ball version of this apparatus reduces the considerable friction by placing large ball bearings between the screw and the nut. At either end of the apparatus, the balls exit from between the two pieces into a channel internal to the box, which connects them with the other end of the apparatus. Thus, they are "recirculated". The recirculating ball mechanism gives

3320-435: The propeller pod only (i.e., Volvo Penta IPS drive). Steering wheels may be used to control the rudder or propeller. Modern ships with diesel-electric drive use azimuth thrusters . Boats powered by oars or paddles are steered by generating a higher propulsion force on the side of the boat opposite of the direction of turn. Jet skis are steered by weight-shift induced roll and water jet thrust vectoring . The rudder of

3403-471: The 1959 Mercedes-Benz W111 Fintail, along with crumple zones. This safety feature first appeared on cars built by General Motors after an extensive and very public lobbying campaign enacted by Ralph Nader . Ford started to install collapsible steering columns in 1968. Audi used a retractable steering wheel and seat belt tensioning system called procon-ten , but it has since been discontinued in favor of airbags and pyrotechnic seat belt pre-tensioners. See

3486-631: The ASNs must be obtained to organise events using their rules, and their licenses must be held by participants. Not all ASNs function in the same manner, some are private companies such as Motorsport UK, some are supported by the state such as France's FFSA, or in the case of the US's ACCUS, a council of sanctioning bodies is the national representative at FIA meetings. ASNs, their affiliated clubs or independent commercial promotors organise motorsport events which often include competitions . A collective of events

3569-552: The Confederation of Australian Motorsport (CAMS). Initially, the cars were based on caricatures of 1940 Ford Coupe and FJ Holden body styles. In 2007, a new era of Aussie Race Car emerged with the design and launch of the Toyota Aurion bodied Aussie Race Car. This new car extended the wheelbase and track on the first generation cars improving performance significantly. Respected design engineer Russell Mapplebeck led

3652-639: The Oshkosh and the Green Bay (the machines were referred to by their town of origin). This is examined and illustrated in detail in The Great Race of 1878 by Richard Backus, Farm Collector, May/June 2004. In 1894, the French newspaper Le Petit Journal organised a contest for horseless carriages featuring a run from Paris to Rouen. This is widely accepted as the world's first motorsport event, and

3735-690: The Oval Racing Council and the National Stock car Association, despite the claim by the FIA affiliated ASN, Motorsport UK , to be the "governing body of all four-wheel motorsport in the UK". SCORE International , National Auto Sport Association and National Off-Road Racing Association of the United States are also not members of the FIA affiliation system but may work with members for international matters. Although English dictionaries do not unanimously agree and singularly define that

3818-409: The amount of assistance is easily tunable to the vehicle type, road speed, and driver preference. An added benefit is the elimination of the environmental hazard posed by leakage and disposal of hydraulic power-steering fluid. In addition, electrical assistance is not lost when the engine fails or stalls, whereas hydraulic assistance stops working if the engine stops, making the steering doubly heavy as

3901-412: The authority of the Fédération Internationale de Motocyclisme (FIM) over vehicles with one to three wheels, which FIM calls motorcycle sport. FIM and FIA are both recognised as international sports federations by the International Olympic Committee . Within the FIA's structure, each affiliated National Sporting Authority ( ASN ) is recognised as the sole authority in their nation. Permission of

3984-460: The capstan and bowstring mechanism) is also found on some home-built vehicles such as soapbox cars and recumbent tricycles . Power steering helps the driver of a vehicle to steer by directing some of its engine power to assist in swiveling the steered road wheels about their steering axes. As vehicles have become heavier and switched to front-wheel drive , particularly using negative offset geometry, along with increases in tire width and diameter,

4067-519: The cars and courses used in special stage rallying with the elements of navigation and itinerary removed, and not necessarily requiring a co-driver to call pacenotes . Rallying involves driving to a set itinerary, following a prescribed route and arriving and departing at control points at set times with penalties applied for diverging from the route or arriving late and early. Rallies nearly always involve routes on open roads, closed special stages are used on some rallies where competitors drive against

4150-516: The character of a particular competition, series or championship. Groups of these are often categorised informally, such as by vehicle type, surface type or propulsion method. Examples of categories within a discipline are formula racing , touring car racing , sports car racing , etc. The first prearranged match race of two self-powered road vehicles over a prescribed route occurred in the north west of England at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, Manchester ,

4233-699: The clock, the winner having the shortest, lowest average or total time. Hillclimbing events often include classes of competition for various categories and ages of vehicle and so may be incorporated into car shows or festivals of motoring such as the Goodwood Festival of Speed . Hill climb courses can be short at less than 1 mile, or several miles long such as the 12.42 mile Pikes Peak course in Colorado , USA. Sprints are governed by national FIA member ASNs in United Kingdom, Ireland and Australia, amongst other places. They are held on courses that do not climb

SECTION 50

4316-519: The clock. The classification of these rallies are determined by summing the times set with the fastest crews being victorious, as found in the World Rally Championship . This method is often called rally racing or stage rallying informally, whilst rallies that do not include special stages are distinctly regularity rallies . Rallies that include routes that cover terrain off-road are also known as rally raid or cross-country rallies,

4399-588: The current 5, 6, and 7 series, as an option. Renault introduced an optional all-wheel steering called '4control' in 2009, at first on the Laguna GT , which is currently available on the Talisman , Mégane and Espace vehicle lines. In 2013, Porsche introduced a system on the 911 Turbo as standard equipment. Since 2016, the Panamera has been offered with optional all-wheel steering. The 2014 Audi Q7

4482-425: The driver can feel the road better and have more precise control over the car's movement. BMW was one of the first manufacturers to adopt rack and pinion steering systems in the 1930s, with many other European manufacturers following suit. Auto manufacturers in the United States began to use rack and pinion steering with the 1974 Ford Pinto . Older designs use two main principles: the worm and sector design and

4565-548: The driver must now turn not only the very heavy steering—without any help—but also the power-assistance system itself. Speed-sensitive steering allows for highly assisted steering at low speeds for maneuverability, and lightly assisted steering at high speed for stability. The first vehicle with this feature was the Citroën SM with its DIRAVI system, first sold in France in 1970. The hydraulic steering system applied force on

4648-493: The effort needed to turn the wheels about their steering axis has increased, often to the point where major physical exertion would be needed were it not for power assistance. To alleviate this, auto makers have developed power steering systems, or more correctly power-assisted steering, since on road-going vehicles there has to be a mechanical linkage as a fail-safe . There are two types of power steering systems: hydraulic and electric/electronic. A hydraulic-electric hybrid system

4731-588: The engineering project alongside James Ward and Blake Hammond. The process to design and build the first "New Age" Aussie Race Car paved the way for future body models, also designed by Mapplebeck, based on the Mercedes-Benz , Holden Cruze , and later the Camaro and Mustang . The category contests an annual Aussie Racing Car Series which is approved by the Confederation of Australian Motor Sport as

4814-439: The general form of time trials and sprints. Hillclimbing is the most widely known form of time-trial due to its status as the only time trial or sprint form to have international FIA championships and endorsement. Its origins begin near the start of motorsport, particularly with the trials held that tested the capabilities of early automobiles to tackle uphill gradients. Contestants complete an uphill course individually and against

4897-447: The general rule of participants completing a course individually with the intention of setting the shortest time or highest average speed. This form of motorsport can be recreational or when competitive, rules may vary slightly such as whether to include the total time of several runs, the best time set, or the average pace of multiple courses to classify competitors. Qualifying sessions for circuit races and special stages in rallying take

4980-774: The grid, raced through the field to win by 2.5 seconds, becoming the first ever woman to win a race in the Aussie Racing Cars category. Two time Series winner, James Duckworth, is the only driver since Mike Russell to win consecutive Drivers' championships. The Aussie Racing Car combines current racing technology and performance in a one-design class where all cars are mechanically identical with strict rules in place to maintain that position. Various body styles are permitted. Originally only 1940 Ford Coupé and Holden FJ body styles were available, with Ford AU Falcon and Holden VY Commodore styles, which replicate V8 Supercars , later made available. A Toyota Aurion body shape

5063-442: The lean of the rider and the bicycle: Ships and boats are usually steered with a rudder . Depending on the size of the vessel, rudders can be manually actuated, or operated using a servomechanism , or a trim tab or servo tab system. Rowing may be used to steer rowboats by using specific paddle strokes . Boats using outboard motors steer by rotating the entire drive unit. Boats with inboard motors sometimes steer by rotating

5146-417: The mid to late 2020s. Traditionally, cars feature a collapsible steering column (energy absorbing steering column) which will collapse in the event of a heavy frontal impact to avoid excessive injuries to the driver. Airbags are also generally fitted as standard. Non-collapsible steering columns fitted to older vehicles very often impaled drivers in frontal crashes, particularly when the steering box or rack

5229-435: The mid-1950s, and some German carmakers did not give up recirculating ball technology until the early 1990s. Other systems for steering exist, but are uncommon on road vehicles. Children's toys and go-karts often use a very direct linkage in the form of a bellcrank (also commonly known as a pitman arm) attached directly between the steering column and the steering arms, and the use of cable-operated steering linkages (e.g.

5312-582: The most famous example being the Dakar Rally . In the United States, the National Off-Road Racing Association (NORRA) was founded in 1967 along with the Baja 1000 . Since the 1990s, this race has been organised by SCORE International whilst NORRA's events have closer followed the FIA regulations and standards for cross country rallies, although the association has no affiliation to ACCUS , the US's FIA member. Drifting

Also known as Autocross in US and Canada and Autoslalom in Continental Europe, these similar disciplines are held in the United Kingdom, Ireland, Australia and New Zealand. They involve precise car control, usually but not always against the clock on very short and compact temporary courses. Rather than being

5478-399: The path taken by the front wheel tracks (e.g. to reduce soil compaction when using rolling farm equipment). Many modern vehicles have passive rear-wheel steering. On many vehicles, when cornering, the rear wheels tend to steer slightly to the outside of a turn, which can reduce stability. The passive steering system uses the lateral forces generated in a turn (through suspension geometry) and

5561-457: The rear axles may be turned through different angles to enable tighter cornering, or through the same angle (crab steering) to move the rear of the trailer laterally. The aim of steer-by-wire technology is to completely remove as many mechanical components (steering shaft, column, gear reduction mechanism, etc.) as possible. Completely replacing conventional steering system with steer-by-wire has several advantages, such as: Steer-by-wire without

5644-456: The rear wheels are steered by a computer and actuators. The rear wheels generally cannot turn as far as the front wheels. There can be controls to switch off the rear steering and options to steer only the rear wheels independently of the front wheels. At low speed (e.g. parking) the rear wheels turn opposite to the front wheels, reducing the turning radius, sometimes critical for large trucks, tractors, vehicles with trailers and passenger cars with

5727-415: The screw and nut. Both types were enhanced by reducing the friction; for screw and nut it is the recirculating ball mechanism, which is still found on trucks and utility vehicles. The steering column turns a large screw, which meshes with the nut by recirculating balls. The nut moves a sector of a gear, causing it to rotate about its axis as the screw is turned; an arm attached to the axis of the sector moves

5810-417: The section § Bicycles . Differential steering is the primary means of steering tracked vehicles , such as tanks and bulldozers; it is also used in certain wheeled vehicles commonly known as skid-steers , and implemented in some automobiles, where it is called torque vectoring , to augment steering by changing wheel direction relative to the vehicle. The bicycle is steered by turning the handlebar and by

5893-527: The sports regulated by FIA (under the name of CIK), permitting licensed competition racing for anyone from the age of 8 onward. It is generally accepted as the most economical form of motorsport available on four wheels. As a free-time activity, it can be performed by almost anybody, and as karting circuits can be indoors and not take as much space as other forms of motorsport, it can be accessible to retail consumers without much qualification or training. Non-racing speed competitions have various names but all carry

5976-460: The technology at the end of the 2005 model year. Nissan/Infiniti offer several versions of their HICAS system as standard or as an option in much of their line-up. In the early 2000s, a new generation of four-wheel steering systems was introduced into the market. In 2001 BMW equipped the E65 7 series with an all-wheel steering system (optional, called 'Integral Active Steering'), which is available on

6059-824: The use of a steering column was first offered in a production car with the Nissan Infiniti Q50 in 2013. Steer-by-wire continued to be offered with the QX50 and QX55, and as of 2022 is being offered with the Infiniti Q60 coupe. Production battery electric vehicles in the 2020s that offer steer-by-wire with no steering column include the Canoo Lifestyle Vehicle , Lexus RZ 450e , REE Automotive P7-module -based vehicles, Toyota bZ4X , and Tesla Cybertruck . As of 2023 Lotus , Peugeot , and Mercedes-Benz plan to offer steer-by-wire cars in

6142-755: The vehicle. This system does not use steering arms, king pins, tie rods, etc. as does four-wheel steering. If the vertical hinge is placed equidistant between the two axles, it also eliminates the need for a central differential in four-wheel drive vehicles, as both front and rear axles will follow the same path, and thus rotate at the same speed. Articulated haulers have very good off-road performance. Vehicle-trailer-combinations such as semi-trailers, road trains , articulated buses , and internal transport trolley trains can be regarded as passively-articulated vehicles. A few types of vehicle use only rear-wheel steering, notably fork lift trucks , camera dollies , early pay loaders , Buckminster Fuller 's Dymaxion car , and

6225-399: The wheel, which tends to make the steering self-centered in the direction of travel. The steering linkages connecting the steering box and the wheels usually conform to a variation of Ackermann steering geometry , to account for the fact that in a turn, the inner wheel travels in a path of smaller radius than the outer wheel, so that the degree of toe suitable for driving in a straight path

6308-549: Was an older design, used for example in Willys and Chrysler vehicles, and the Ford Falcon (1960s). To reduce friction, the sector is replaced by a roller or rotating pins on the rocker shaft arm. Generally, older vehicles use the recirculating ball mechanism, and only newer vehicles use rack-and-pinion steering. This division is not very strict, however, and rack-and-pinion steering systems can be found on British sports cars of

6391-661: Was developed from a scrapped John Bridge Adams light-rail vehicle. These were solid fired steam carriages. This event and the details of the vehicles are recorded in the contemporary press, The Engineer , and in Fletcher's books. The Wisconsin legislature passed an act in 1875 offering a substantial purse for the first US motor race, which was run on July 16, 1878, over a 200-mile course from Green Bay to Appleton, Oshkosh, Waupon, Watertown, Fort Atkinson and Janesville, then turning north and ending in Madison. Only two actually competed:

6474-441: Was launched in 2008, followed by a Holden Cruze in 2012 and a Mercedes-Benz inspired "Euro GT" in 2013. Nissan Altima , Ford Mustang , and Chevrolet Camaro were added in 2014. Hyundai Elantra debuted during the 2015 series. Cars are constructed on a purpose-built steel tubular space frame chassis with integral roll cage construction designed and approved to stringent engineering specifications. The lightweight composite body

6557-714: Was launched with an optional system. Also the Japanese OEMs offer luxury segment vehicles equipped with all-wheel steering, such as Infiniti on its QX70 model ('Rear Active Steering') and Lexus on the GS. Italian manufacturers have launched the technology in the model years 2016–17 with the Ferrari F12tdf , the Ferrari GTC4Lusso as well as the Lamborghini Aventador S . Crab steering is

6640-412: Was mounted in front of the front axle line, at the front of the crumple zone . This was particularly a problem on vehicles that had a rigid separate chassis frame with no crumple zone. Many modern vehicle steering boxes or racks are mounted behind the front axle on the front bulkhead, at the rear of the front crumple zone. Collapsible steering columns were invented by Béla Barényi and were introduced in

6723-483: Was the first purpose-built motor racing track in the world. After which, permanent autodromes popularly replaced circuits on public roads. In North America, the term road racing is used to describe racing and courses that have origins in racing on public highways; distinguished from oval racing , which has origins at purpose-built speedways using concrete or wooden boards . Off-road racing can take place on open terrain with no set path, or on circuits that do not have

6806-645: Was the first to involve what would become known as automobiles. On 28 November 1895, the Chicago Times-Herald race , running from Chicago to Evanston and back, a distance of sixty miles, was held. This is believed to be the first motorsport event in the United States of America. In 1900, the Gordon Bennett Cup was established. Motorsport was a demonstration event at the 1900 Summer Olympics . Following World War I , European countries organised Grand Prix races over closed courses. In

6889-485: Was used on a production pickup truck, the Tesla Cybertruck, in 2023. Four-wheel steering is a system employed by some vehicles to improve steering response, increase vehicle stability while maneuvering at high speed, or to decrease turning radius at low speed. In an active four-wheel steering system, all four wheels turn at the same time when the driver steers. In most active four-wheel steering systems,
