BMW V12 LMR
The BMW V12 LMR is a Le Mans Prototype built for sports car racing from 1999 to 2000. The car was built through an alliance between BMW Motorsport and Williams F1, and was the successor to the failed BMW V12 LM of 1998. It is famous for earning BMW its only overall victory to date at the 24 Hours of Le Mans. Development Immediately following the 1998 24 Hours of Le Mans in which both BMW V12 LMs had failed to finish due to mechanical difficulties and a slow pace caused by aerodynamic inefficiencies, BMW Motorsport made the decision to radically revamp their sportscar project and quickly replace the V12 LM with a new car for 1999, the V12 LMR. The V12 LMR would retain only the basic structures of the V12 LM, while all of the car's bodywork was redone from scratch. The cooling ducts, a major problem on the V12 LM, were moved to the top of the car instead of from the bottom where it had suffered from ambient track heat. Among the more radical design features was the use of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Le Mans Prototype
A Le Mans Prototype (LMP) is the type of sports prototype race car used in the 24 Hours of Le Mans, FIA World Endurance Championship, IMSA SportsCar Championship, European Le Mans Series and Asian Le Mans Series. Le Mans Prototypes were created by the Automobile Club de l'Ouest (ACO). The technical requirements for an LMP include bodywork covering all mechanical elements of the car. Currently, there are three classes within Le Mans Prototypes, designated LMP1, LMP2, and LMP3. While not as fast as open-wheel Formula One cars around a track, LMP1s were the fastest closed-wheel racing cars used in circuit racing. Le Mans Prototypes are considered a class above production-based grand tourer cars, which compete alongside them in sports car racing. Later LMP1 designs included Hybrid vehicle, hybrid cars that use electric motors to assist acceleration. The Le Mans Prototype LMP1 class has been replaced by Le Mans Hypercars in the FIA World Endurance Championship, and the 24 Hours of ...

Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of which ...

Sports Car Racing
Sports car racing is a form of motorsport road racing which utilises sports cars that have two seats and enclosed wheels. They may be purpose-built prototypes or grand tourers based on road-going models. Broadly speaking, sports car racing is one of the main types of circuit auto racing, alongside open-wheel single-seater racing (such as Formula One), touring car racing (such as the British Touring Car Championship, which is based on 'saloon cars' as opposed to the 'exotics' seen in sports cars) and stock car racing (such as NASCAR). Sports car races are often, though not always, endurance races that are run over relatively large distances, and there is usually a larger emphasis placed on the reliability and efficiency of the car as opposed to outright speed of the driver. The FIA World Endurance Championship is an example of a sports car racing series. A type of hybrid between the purism of open-wheelers and the familiarity of touring car racing, this style is often associate ...

Sequential Manual Gearbox
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 time Shift time refers to the time interval between gear changes in a transmission. This interval is the time in which power delivery is transferred to the next selected gear, and engine speed is reduced or increased to synchronize the speed of the n ...s 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 non-synchronous transmission, 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 sh ...

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and ...
