Chaparral 2F
The Chaparral 2F is a Group 6 sports prototype designed by Jim Hall and Hap Sharp, and built under their company Chaparral Cars. Built with the intention to compete in the World Sportscar Championship, it competed in the 1967 season, with a best finish of first at the BOAC 500, driven by Phil Hill and Mike Spence. The 2F, alongside its predecessor the 2E, had a heavy influence in dictating the direction of Formula One car design in the late 1960s and early 1970s, with a larger emphasis on aerodynamic efficiency. Background The importance and role of aerodynamics was still in its infancy in motorsports in the 1960s. Michael Mayer was the first to try a rear aerofoil at the 1956 1000 km of Nürburgring with his Porsche 550 Spyder, where he mounted a wing just above the driving position, but was eventually forced by scrutineers to remove it. In 1965, Jim Hall, alongside colleagues at General Motors, collaborated in experimenting with rear aero structures, which resulted in a sm ...

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 de ...

Chevrolet
Chevrolet ( ), colloquially referred to as Chevy and formally the Chevrolet Motor Division of General Motors Company, is an Automotive industry in the United States, American automobile division of the American manufacturer General Motors (GM). Louis Chevrolet (1878–1941) and ousted General Motors founder William C. Durant (1861–1947) started the company on November 3, 1911 as the Chevrolet Motor Car Company. Durant used the Chevrolet Motor Car Company to acquire a controlling stake in General Motors with a reverse takeover, reverse merger occurring on May 2, 1918, and propelled himself back to the GM presidency. After Durant's second ousting in 1919, Alfred Sloan, with his Maxim (saying), maxim "a car for every purse and purpose", would pick the Chevrolet brand to become the volume leader in the General Motors family, selling mainstream vehicles to compete with Henry Ford's Ford Model T, Model T in 1919 and overtaking Ford Motor Company, Ford as the best-selling car in the ...

Michael May (racing Driver)
Michael May (born 18 August 1934 in Stuttgart, Germany) is a former racing driver and engineer from Switzerland. He participated in three Formula One World Championship Grands Prix, debuting on 14 May 1961. He scored no championship points. After a crash during practice for the 1961 German Grand Prix, May concentrated on engineering, helping to develop a fuel injection system for Porsche and Ferrari. May is generally credited with introducing the first manipulated elevated wing onto a racing car - a Porsche 550 Spyder- to produce downforce (or down thrust) for enhanced braking and cornering speeds to reduce lap times. The modified 550 was entered by May and his brother Pierre in the 1956 1000km of Nürburgring. During qualifying, the car lapped the circuit four seconds faster than the Porsche factory team 550s. However, race organizers disqualified the car following a complaint by Porsche racing director Huschke von Hanstein. The wing was removed for the remainder of the car' ...

Motor Sport (magazine)
''Motor Sport'' is a monthly motor racing magazine, founded in the United Kingdom in 1924 as the ''Brooklands Gazette''. The name was changed to ''Motor Sport'' for the August 1925 issue. The magazine covers motor sport in general, although from 1997 to 2006 its emphasis was historic motorsport. It remains one of the leading titles on both modern and historic racing. The magazine's photo library is currently managed by LAT Images, which founded as Motor Sport photographic division by Wesley J. Tee in the 1960s and later spun-off as a stand-alone affiliated company. The magazine's monthly podcasts have featured Christian Horner, Mario Andretti, Patrick Head, Sir Frank Williams, John McGuinness and Gordon Murray. In 1939 the magazine incorporated its rival ''Speed'' (the organ of the British Racing Drivers' Club).

BOAC 500
The Brands Hatch 1000 km was an endurance sports car event that was part of the World Sportscar Championship for varying years from 1967 until 1989. Originally a six-hour race running under the name BOAC 500, the event was eventually extended to 1000 kilometres under a number of different sponsorship titles. History In 1966, a non-championship sports car race was held at Brands Hatch for a distance of 500 miles, with drivers David Piper and Bob Bondurant easily taking victory in an AC Cobra. With the success of this initial event, the World Sportscar Championship would add Brands Hatch to their calendar, while the British Sports Car Championship replaced their Guards Trophy event. However, unlike the initial race's set distance of 500 miles, the new event would be run for six hours. Even with a timed race, BOAC stepped in as the primary sponsor and chose to retain the 500 mile distance in the name, earning the popular title BOAC 500. The 1968 race took place on 7 April, ...

1967 World Sportscar Championship
The 1967 World Sportscar Championship season were the 15th season of FIA World Sportscar Championship racing. It featured the International Championship for Sports-Prototypes and the International Championship for Sports Cars. The former was open to Group 6 Sports-Prototypes and the latter to Group 4 Sports Cars. The season ran from 4 February 1967 to 3 September 1967 and comprised 14 races in total. This was the last championship season to include a hill climb event, due to safety concerns. Also, growing speed at Le Mans caused a controversial CSI decision to limit the engine capacity of Group 6 Sports-Prototypes to 3 litres, beginning in 1968. Schedule Although the season was composed of 14 races, not all races counted as rounds for both championships János L Wimpffen. Time and Two Seats, 1999, page 708Introduction: ...

World Sportscar Championship
The World Sportscar Championship was the world series run for sports car racing by the FIA from 1953 to 1992. The championship evolved from a small collection of the most important sportscar, endurance, and road racing events in Europe and North America with dozens of gentleman drivers at the grid, to a professional racing series where the world's largest automakers spent millions of dollars per year. The official name of the series changed throughout the years, however it has generally been known as the World Sportscar Championship from its inception in 1953. The World Sportscar Championship was, with the Formula One World Championship, one of the two major world championships in circuit motor racing. In 2012 the World Sportscar Championship was revived and renamed as the World Endurance Championship. Races The most famous event was the 24 Hours of Le Mans which was the part of the championship in every season except of the 1956, 1975– 79 and 1989– 90 seasons. ...

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 championship ...

Automatic Transmission
An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission (mechanics), transmission used in internal combustion engine-based motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. It typically includes a transmission, axle, and Differential (mechanical device), differential in one integrated assembly, thus technically becoming a transaxle. The most common type of automatic transmission is the #Hydraulic automatics, hydraulic automatic, which uses a planetary gearset, Hydraulic machinery, hydraulic controls, and a torque converter. Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT). An electronic automatic transmission (EAT) may also be called an electronically controlled transmission (ECT), or electronic automatic transaxle (EATX). A hydraulic automatic transmission may ...

Natural Aspiration
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant " birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word '' physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by ...

Longitudinal Engine
In automotive engineering, a longitudinal engine is an internal combustion engine in which the crankshaft is oriented along the long axis of the vehicle, front to back. Use This type of motor is usually used for rear-wheel drive cars, except for some Audi and SAAB models equipped with longitudinal engines in front wheel drive. In front-wheel drive cars a transverse engine is usually used. Trucks often have longitudinal engines with rear-wheel drive. For motorcycles, the use of a particular type depends on the drive: in case of a chain or belt drive a transverse engine is usually used, and with shaft drives a longitudinal engine. Longitudinal engines in motorcycles do have one disadvantage: the "tipping point" of the crankshaft tilts along the entire motorcycle to a greater or lesser degree when accelerating. This is partly resolved by having other components, such as the generator and the gearbox, rotate in the opposite direction to the crankshaft. Most larger, "premium" ...
