Mazda
, commonly referred to as simply Mazda, is a Japanese multinational automotive manufacturer headquartered in Fuchū, Hiroshima, Japan. In 2015, Mazda produced 1.5 million vehicles for global sales, the majority of which (nearly one million) were produced in the company's Japanese plants, with the remainder coming from a variety of other plants worldwide. During this time, Mazda was the 15th-largest automaker in terms of production globally. History Creation Mazda began as the Toyo Cork Kogyo Co., Ltd, as a cork-making factory founded in Hiroshima, Japan, 30 January 1920. Toyo Cork Kogyo renamed itself to Toyo Kogyo Co., Ltd. in 1927. In the late 1920s the company had to be saved from bankruptcy by Hiroshima Saving Bank and other business leaders in Hiroshima. In 1931, Toyo Kogyo moved from manufacturing machine tools to vehicles with the introduction of the Mazda-Go auto rickshaw. The name ''Mazda'' came into existence with the production of the company's fi ... [...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] |
Racing Car
Auto racing (also known as car racing, motor racing, or automobile racing) is a motorsport involving the racing of automobiles for competition. Auto racing has existed since the invention of the automobile. Races of various sorts were organised, with the first recorded as early as 1867. Many of the earliest events were effectively reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for automobile makers to demonstrate their machines. By the 1930s, specialist racing cars had developed. There are now numerous different categories, each with different rules and regulations. History The first prearranged match race of two self-powered road vehicles over a prescribed route occurred at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, a distance of eight miles. It was won by the carriage of Isaac Watt Boulton. Internal combustion auto racing events began soon after the constructio ...

Mazdaspeed
(often stylized in all-caps as MAZDASPEED) was Mazda's in-house performance division. The company was a grassroots racing team in Japan. Owned by Mazda Motor Corporation, they built production model vehicles, became involved in motorsports development, and offered performance parts and accessories. History Mazdaspeed began in 1967 as "Mazda Sports Corner", an independent racing team and tuning operation run by Takayoshi Ohashi, who also ran Mazda's Tokyo distributor. They competed in numerous events at home and abroad, and they were also competitive at the 24 Hours of Le Mans races in the early 1980s, with the 717, 727, and 737. Mazda brought the racing team to Hiroshima in 1983, where the name became Mazdaspeed. In 1991, Mazdaspeed's 787B won at Le Mans, a feat no other Japanese team managed until Toyota did in 2018. After the FIA effectively outlawed the Wankel engine as well as Mercedes's Flat 12 engine the next year, the Mazdaspeed team raced one more year at Le Mans in a ...

24 Hours Of Le Mans
The 24 Hours of Le Mans (french: link=no, 24 Heures du Mans) is an endurance-focused Sports car racing, sports car race held annually near the town of Le Mans, France. It is the world's oldest active Endurance racing (motorsport), endurance racing event. Unlike fixed-distance races whose winner is determined by minimum time, the 24 Hours of Le Mans is won by the car that covers the greatest distance in 24 hours. The cars on this track can go up to , and in prior events reaching before track modifications. Racing teams must balance the demands of speed with the cars' ability to run for 24 hours without mechanical failure. The race is organized by the Automobile Club de l'Ouest (ACO).

Group C
Group C was a category of sports car racing introduced by the FIA in 1982 and continuing until 1993, with ''Group A'' for touring cars and ''Group B'' for GTs. It was designed to replace both Group 5 special production cars (closed top touring prototypes like Porsche 935) and Group 6 two-seat racing cars (open-top sportscar prototypes like Porsche 936). Group C was used in the FIA's World Endurance Championship (1982–1985), World Sports-Prototype Championship (1986–1990), World Sportscar Championship (1991–1992) and in the European Endurance Championship (1983 only). It was also used for other sports car racing series around the globe (All Japan Sports Prototype Championship, Supercup, Interserie). The final year for the class came in 1993. Broadly similar rules were used in the North American IMSA Grand Touring Prototype series ( GTP). History The roots of the Group C category lie in both FIA Group 6 and particularly in the GTP category introduced by the ACO at ...

Mazda RX-7
The Mazda RX-7 is a front-engine, rear-wheel-drive, rotary engine-powered sports car that was manufactured and marketed by Mazda from 1978 until 2002 across three generations, all of which made use of a compact, lightweight Wankel rotary engine. The first generation of the RX-7, SA (early) and FB (late), was a two-seater 2 door hatchback coupé. It featured a 12A carbureted rotary engine as well as the option for a 13B with electronic fuel injection in later years. The second generation of RX-7, known as the FC, was offered as a 2-seater coupé with a 2+2 option available in some markets, as well as in a convertible bodystyle. This was powered by the 13B rotary engine, offered in naturally aspirated or turbocharged forms. The third generation of the RX-7, known as the FD, was offered a 2+2-seater coupé with a limited run of a 2-seater option. This featured a sequentially turbocharged 13B REW engine. More than 800,000 were manufactured over its lifetime. __TOC__ First gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mazda Wankel Engine
The Mazda Wankel engines are a family of Wankel rotary combustion car engines produced by Mazda. Wankel engines were invented in the early 1950s by Felix Wankel, a German engineer. Over the years, displacement has been increased and turbocharging has been added. Mazda rotary engines have a reputation for being relatively small and powerful at the expense of poor fuel efficiency. The engines became popular with kit car builders, hot rodders and in light aircraft because of their light weight, compact size, tuning potential and inherently high power-to-weight ratio—as is true for all Wankel-type engines. Mazda put the engine into series production with NSU ( Ro80) and Citroën ( GS Birotor) as part of the Comotor joint-venture between 1967 and 1977. Since the end of production of the Mazda RX-8 in 2012, the engine was produced only for single seater racing, with the one-make Star Mazda Championship being contested with a Wankel engine until 2017; the series' transition to usi ...

Wankel Engine
The Wankel engine (, ) is a type of internal combustion engine using an Eccentric (mechanism), eccentric rotary combustion engine, rotary design to convert pressure into rotating motion. It was invented by German engineer Felix Wankel, and designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor, which creates the turning motion, is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor rotates inside an oval-like epitrochoidal housing, around a central output shaft. The rotor spins in a hula-hoop fashion around the central output shaft, spinning the shaft via toothed gearing. Due to its inherent poor thermodynamics, the Wankel engine has a significantly worse thermal efficiency and worse exhaust gas behaviour when compared against the Otto engine or the Diesel engine, which is why the Wankel engine has seen limited use since its introduction in the 1960s. However, its advantages of compact design, smoothness, lower weight and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mazda 727C
The Mazda 727C is a prototype racing car that was built for Mazdaspeed for the 24 Hours of Le Mans in the Group C2 class. It replaced the 717C in 1984 as an evolution of the Mooncraft-built design, and used the same 2-rotor '' 13B'' Wankel engine as the previous model. Two 727Cs were entered in the 1984 24 Hours of Le Mans, finishing 4th and 6th in the C2 class. However, a pair of Lola T616s run by B.F. Goodrich Company used the same Mazda engine and were successful in beating both 727Cs, claiming 1st and 3rd. The 727C was used a few more times in the 1984 World Sportscar Championship season The 1984 World Sportscar Championship season was the 32nd season of FIA "World Sportscar Championship" motor racing. It featured the 1984 FIA World Endurance Championship, which was open to FIA Group C1, Group C2 and Group B cars and to IMSA GTP, ..., managing a mere 10th place in the C2 manufacturer's championship, behind two separate teams of privateers.
