Mitsubishi Lancer WR05
The Mitsubishi Lancer WRC is a World Rally Car built by Ralliart, Mitsubishi Motors' motorsport division, to compete in the World Rally Championship. The previous Lancer Evolution series were homologated for the Group A class, and their competitiveness against World Rally Cars from other manufacturers was therefore limited. WRC The Lancer Evolution WRC is powered by the same 1996 cc ''4G63'' engine that has been used in its sports and rally cars since the 1980s, in this iteration producing at 5500 rpm and at 3500 rpm. The car debuted at the 2001 Rallye Sanremo, after a relatively short development (Ralliart could not introduce the Lancer WRC later because of a contract they made with the FIA in 1999, which allowed them to run the old specification Lancers). The model was based on the then-new eighth-generation Cedia model, of which the road-going Evolution VII is based on. The WRC rules allowed more freedom in most areas of the car, therefore the engineers were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Rally Car
A World Rally Car is a racing automobile built to the specific regulations set by the Fédération Internationale de l'Automobile (FIA) and designed for competition in the World Rally Championship (WRC). The cars were introduced in 1997 as a replacement for Group A regulations used in the manufacturers' championship, and were replaced by Group Rally1 in 2022. Regulations 1997–2010 Between 1997 and 2010, the regulations mandated that World Rally Cars must have been built upon a production car with a minimum production run of 2500 units. A number of modifications could be made including increasing the engine displacement up to 2.0L, forced induction (including an anti-lag system), addition of four wheel drive, fitment of a sequential gearbox, modified suspension layout and attachment points, aerodynamic body modifications, weight reduction to a minimum of 1230 kg and chassis strengthening for greater rigidity. The maximum width was set at 1770 mm while front and rear tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Group A
Group A is a set of motorsport regulations administered by the FIA covering production derived vehicles intended for competition, usually in touring car racing and rallying. In contrast to the short-lived Group B and Group C, Group A vehicles were limited in terms of power, weight, allowed technology and overall cost. Group A was aimed at ensuring numerous entries in races of privately owned vehicles. Group A was introduced by the FIA in 1982 to replace the outgoing Group 2 as "modified touring cars", while Group N would replace Group 1 as "standard touring cars". During the early years there were no further formula for production based race cars. Cars from multiple Groups could contest the World Rally Championship for Manufacturers for example until 1997 when the specific World Rally Car formula was introduced as the only option. In recent years Groups A and N have begun to be phased out in eligibility in championships though they continue to form the homologation basis for mos ...

Brake
A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction. Background Most brakes commonly use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat, though other methods of energy conversion may be employed. For example, regenerative braking converts much of the energy to electrical energy, which may be stored for later use. Other methods convert kinetic energy into potential energy in such stored forms as pressurized air or pressurized oil. Eddy current brakes use magnetic fields to convert kinetic energy into electric current in the brake disc, fin, or rail, which is converted into heat. Still other braking methods even transform kinetic energy into different forms, for example by transferring the energy to a rotating flywheel. Brakes are generally ...

Coil Spring
A selection of conical coil springs The most common type of spring is the coil spring, which is made out of a long piece of metal that is wound around itself. Coil springs were in use in Roman times, evidence of this can be found in bronze Fibulae - the clasps worn by Roman soldiers among others. These are quite commonly found in Roman archeological digs. Coil springs can be either compression springs, tension springs or torsion springs, depending on how they are wound. A coil spring is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded. They are commonly used in mattresses, automotive suspensions, and residential plumbing. Coil springs come in a variety of sizes and shapes and can be used for a variety of applications. Small coil springs are often us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Independent Suspension
Independent suspension is any automobile suspension system that allows each wheel on the same axle to move vertically (i.e. reacting to a bump on the road) independently of the others. This is contrasted with a beam axle or deDion axle system in which the wheels are linked. "Independent" refers to the motion or path of movement of the wheels or suspension. It is common for the left and right sides of the suspension to be connected with anti-roll bars or other such mechanisms. The anti-roll bar ties the left and right suspension spring rates together but does not tie their motion together. Most modern vehicles have independent front suspension (IFS). Many vehicles also have an independent rear suspension (IRS). IRS, as the name implies, has the rear wheels independently sprung. A fully independent suspension has an independent suspension on all wheels. Some early independent systems used swing axles, but modern systems use Chapman or MacPherson struts, trailing arms, multilink, or ...

Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/ handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different. History An early form of suspension on ox-drawn carts had the platform swing on iron chains attached to the wheeled frame of the carriage. This system remained the basis for most suspension systems until the turn of the 19th century, although the iron cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Differential
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel maki ...

Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the ...

Carbon
Carbon () is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent In chemistry, the valence (US spelling) or valency (British spelling) of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules. Description The combining capacity, or affinity of an ...—its atom making four electrons available to form covalent bond, covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust. Three Isotopes of carbon, isotopes occur naturally, Carbon-12, C and Carbon-13, C being stable, while Carbon-14, C is a radionuclide, decaying with a half-life of about 5,730 years.

Sequential Manual Transmission
A sequential manual transmission, also known as a sequential gearbox, or a sequential transmission, is a type of non-synchronous manual transmission used mostly for motorcycles and racing cars. It produces faster shift times than traditional synchronized manual transmissions, and restricts the driver to selecting either the next or previous gear, in a successive order. Design A sequential manual transmission is unsynchronized, and allows the driver to select either the next gear (e.g. shifting from first gear to second gear) or the previous gear (e.g., shifting from third gear to second gear), operated either via electronic paddle-shifters mounted behind the steering wheel or with a sequential shifter. This restriction avoids accidentally selecting the wrong gear; however, it also prevents the driver from deliberately "skipping" gears. The use of dog clutches (rather than synchromesh) results in faster shift speeds than a conventional manual transmission. On a sequentia ...

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-f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tommi Mäkinen
Tommi Antero Mäkinen (; born 26 June 1964) is a Finnish racing executive and former driver. Mäkinen is one of the most successful WRC drivers of all time, ranking fifth in rally wins (24) and third in championships (4), tied with Juha Kankkunen behind Sébastien Ogier (8) and Sébastien Loeb (9). In 2018, as a head of Toyota Gazoo Racing WRT, he became the first person in the history of rally driving to win a Championship both as a driver and as a team principal. He is a four-time World Rally Champion, a series he first won, and then successfully defended, continuously throughout 1996, 1997, 1998 and 1999, on all occasions driving the Ralliart Mitsubishi Lancer Evolution. He also aided Mitsubishi to the 1998 world constructors' title as well as winning the 2000 Race of Champions. Mäkinen's navigators include compatriots Seppo Harjanne, Kaj Lindström and Risto Mannisenmäki, the former retiring from alongside Mäkinen having previously served 1985 champion, and fellow "Flyi ...
