McMurtry Spéirling
The McMurtry Spéirling is a record breaking electric single-seat prototype car which was first presented at the Goodwood Festival of Speed in 2021. The car is developed by McMurtry Automotive, a British registered startup founded on June 2nd 2016 by Sir David McMurtry (co-founder and executive chairman of Renishaw plc). "Spéirling" is Irish for "thunderstorm". History According to McMurtry, the motivation behind the car was to challenge the industry trend of increasingly heavier vehicles and, by using first principles design, create a lightweight electric drivers car. The prototype car is the first step to demonstrate what customers will experience on road and track. It is not currently in a racing series but is built to satisfy relevant motorsport safety requirements, with crash structures and a carbon-fibre monocoque chassis with integral rollover protection. Its unique performance differentiator is the fan powered downforce system, giving 2,000kg of downforce from 0mph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Prototype
A sports prototype, sometimes referred to as simply a prototype, is a type of race car that is used in the highest-level categories of sports car racing. These purpose-built racing cars, unlike street-legal and production-based racing cars, are not intended for consumer purchase or production beyond that required to compete and win races. Prototype racing cars have competed in sports car racing since before World War II, but became the top echelon of sports cars in the 1960s as they began to replace homologated sports cars. Current ACO regulations allow most sports car series to use two forms of cars: grand tourers (GT), based on street cars, and prototypes, which are allowed a great amount of flexibility within set rule parameters. In historic racing, they are often called "sports racing cars". Sometimes, they are incorrectly referred to as "Le Mans cars", whether they are competing in the Le Mans race or not. Types of sports prototypes Since the 1960s, various championships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carwow
Carwow is an online marketplace for buying and selling cars. It uses the reverse marketplace model to remove the need for customers to negotiate with dealers when buying or selling their cars. When buying a new car, users choose the car they would like to buy, along with the various specifications and features, and then receive offers directly from dealers. When selling a car, users upload some basic details about their car (such as the registration number, mileage and some photos), after which different car dealers are invited to bid to buy the car directly from them. It also provides information to prospective purchasers and gives feedback on rogue dealers. The company has a YouTube page, run by motor journalist and Carwow's Chief Content Officer Mat Watson, where different cars are reviewed. The company has partnered with the RAC as part of RAC Cars' ‘search, buy, sell’ website. Carwow was co founded by James Hind, Alexandra Margolis, and David Santoro and launched in M ...

Formula One Car
A Formula One car (also known as an F1 car) is a single-seat, open-cockpit, open-wheel formula racing car with substantial front and rear wings, and an engine positioned behind the driver, intended to be used in competition at Formula One racing events. The regulations governing the cars are unique to the championship and specify that cars must be constructed by the racing teams themselves, though the design and manufacture can be outsourced. Formula One cars are the fastest cars in the world around a race track, owing to very high cornering speeds achieved through the generation of large amounts of aerodynamic downforce. As a result of the amount of braking force and the total cornering envelope of a Formula One car (by the friction component of the tyre, the mass of the machine and the downforce generated); Formula One drivers experience frequent lateral g-loadings in excess of five g, and peak cornering forces of up to seven lateral g.

Brabham BT46
The Brabham BT46 is a Formula One racing car designed by Gordon Murray for the Brabham team, owned by Bernie Ecclestone, for the 1978 Formula One season. The car featured several radical design elements, one of which was the use of flat panel heat exchangers on the bodywork of the car to replace conventional water and oil radiators. It was removed before the car's race debut, never to be seen again. The cars, however, powered by a flat-12 Alfa Romeo engine, raced competitively with modified nose-mounted radiators for most of the year, driven by Niki Lauda and John Watson, winning one race in this form and scoring sufficient points for the team to finish third in the constructors championship. The "B" variant of the car, also known as the "fan car", was introduced at the 1978 Swedish Grand Prix as a counter to the dominant ground-effect Lotus 79. The BT46B generated an immense amount of downforce by means of a fan, claimed to be for increased cooling, but which also extract ...

Can-Am
The Canadian-American Challenge Cup, or Can-Am, was an Sports Car Club of America, SCCA/Canadian Auto Sport Clubs, CASC sports car racing series from 1966 to 1987. History Can-Am started out as a race series for group 7 sports racers with two races in Canada (''Can'') and four races in the United States of America (''Am''). The series was initially sponsored by S. C. Johnson & Son, Johnson Wax. The series was governed by rules called out under the Fédération Internationale de l'Automobile, FIA Group 7 (racing), group 7 category with unrestricted engine capacity and few other technical restrictions. The group 7 category was essentially a Formula Libre for sports cars; the regulations were minimal and permitted unlimited engine sizes (and allowed turbocharging and supercharging), virtually unrestricted aerodynamics, and were as close as any major international racing series ever got to have an "anything goes" policy. As long as the car had two seats, bodywork enclosing the wheel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaparral Cars
Chaparral Cars was a pioneering American automobile racing team and race car developer that engineered, built, and raced cars from 1963 through 1970. Founded in 1962 by American Formula One racers Hap Sharp and Jim Hall, it was named after the roadrunner, a fast-running ground cuckoo also known as a ''chaparral bird''. Background Dick Troutman and Tom Barnes were builders of the original Chaparral race cars (later referred to as Chaparral 1). Jim Hall purchased two Chaparral 1s to race. When Hall and Sharp began building their own cars, they asked Troutman and Barnes if they could continue to use the Chaparral name. That is why the Hall/Sharp cars are all named Chaparral 2s (models 2A through 2J for sports cars/CanAm cars, and the 2K which was the 1979–1982 Indycar). Despite winning the Indianapolis 500 in 1980, they left motor racing in 1982. Chaparral cars also featured in the SCCA/ CASC Can-Am series and Endurance racing. Jim Hall was a leader in the innovation and des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jim Hall (racing Driver)
Jim Hall (born July 23, 1935 in Abilene, Texas) is a retired American racing driver, race car constructor, and team owner. While he is best known as a car constructor, he was one of the greatest American racing drivers of his generation, capturing consecutive United States Road Racing Championships (1964, 1965), two Road America 500s (1962, 1964), two Watkins Glen Grands Prix for sports cars (1964, 1965), the 1965 Canadian Grand Prix for sports cars, the 1965 Pacific Northwest Grand Prix, and scoring a massive upset at the 1965 12 Hours of Sebring over a contingent of factory-backed Ford GTs, Shelby Daytona Coupes and Ferrari entries. If anything Hall's accomplishments behind the wheel have been overshadowed by his pivotal contributions to race car design through his series of Chaparral sports racing and Indy cars. Hall's cars won in every series in which they competed: USRRC, Can-Am, Trans-Am, Formula 5000, World Sportscar Championship, Autoweek Championship, Canadian Sports Car C ...

Jet Engine
A jet engine is a type of reaction engine discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition can include rocket, Pump-jet, water jet, and hybrid propulsion, the term typically refers to an internal combustion airbreathing jet engine such as a turbojet, turbofan, ramjet, or pulse jet engine, pulse jet. In general, jet engines are internal combustion engines. Airbreathing jet engines typically feature a Axial compressor, rotating air compressor powered by a turbine, with the leftover power providing thrust through the propelling nozzle—this process is known as the Brayton cycle, Brayton thermodynamic cycle. Jet aircraft use such engines for long-distance travel. Early jet aircraft used turbojet engines that were relatively inefficient for subsonic flight. Most modern subsonic jet aircraft use more complex High-bypass turbofan, high-bypass turbofan engines. They give higher speed and greater fuel eff ...

Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 10 (approximately ). The unit expresses a relative change or an absolute value. In the latter case, the numeric value expresses the ratio of a value to a fixed reference value; when used in this way, the unit symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is " V" (e.g., "20 dBV"). Two principal types of scaling of the decibel are in common use. When expressing a power ratio, it is defined as ten times the logarithm in base 10. That is, a change in ''power'' by a factor of 10 corresponds to a 10 dB change in level. When expressing root-power quantities, a change in ''ampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downforce
Downforce is a downwards lift force created by the aerodynamic features of a vehicle. If the vehicle is a car, the purpose of downforce is to allow the car to travel faster by increasing the vertical force on the tires, thus creating more grip. If the vehicle is a fixed-wing aircraft, the purpose of the downforce on the horizontal stabilizer is to maintain longitudinal stability and allow the pilot to control the aircraft in pitch. Fundamental principles The same principle that allows an airplane to rise off the ground by creating lift from its wings is used in reverse to apply force that presses the race car against the surface of the track. This effect is referred to as "aerodynamic grip" and is distinguished from "mechanical grip", which is a function of the car's mass, tires, and suspension. The creation of downforce by passive devices can be achieved only at the cost of increased aerodynamic drag (or friction), and the optimum setup is almost always a compromise between ...

Rear-wheel Drive
Rear-wheel drive (RWD) is a form of engine and transmission layout used in motor vehicles, in which the engine drives the rear wheels only. Until the late 20th century, rear-wheel drive was the most common configuration for cars. Most rear-wheel drive vehicles feature a longitudinally-mounted engine at the front of the car. Layout The most common layout for a rear-wheel drive car is with the engine and transmission at the front of the car, mounted longitudinally. Other layouts of rear-wheel drive cars include front-mid engine, rear-mid engine, and rear-engine. Some manufacturers, such as Alfa Romeo, Lancia, Porsche (944, 924, 928) and Chevrolet (C5, C6, and C7 Corvettes), place the engine at the front of the car and the transmission at the rear of the car, in order to provide a more balanced weight distribution. This configuration is often referred to as a transaxle since the transmission and axle are one unit. History 1890s to 1960s Many of the cars built in the 19t ...

GT4 European Series
The GT4 European Series is a sports car championship created and organised by SRO Motorsports Group. It is a pro/am championship which followed a formula similar to the FIA GT3 European Championship, which was itself derived from the FIA GT Championship which utilized the GT1 and GT2 classes. The GT4 class cars are the least powerful of the four classes, yet are equalised in order to allow driving skill to become key. History Following the successful introduction of the FIA GT3 European Championship in 2006, the formula was expanded to include usage by other nationally based professional championships such as the British GT Championship, Belcar, Australian GT Championship and German ADAC GT Masters. While the FIA GT3 European Championship continues, the SRO felt that a true amateur championship was needed in order to complement GT3 which allowed a certain level of professional driver to compete. Many national series also adopted the GT4 regulations as a lower class, and the Euro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
