Supercar is a term generally used for a high-end sports car, whose performance is highly superior to that of its contemporaries. It has been defined specifically as "a very expensive, fast or powerful car with a centrally located engine"[1], and stated in more general terms: "it must be very fast, with sporting handling to match," "it should be sleek and eye-catching" and its price should be "one in a rarified atmosphere of its own."[2] but the proper application of the term is subjective and disputed, especially among enthusiasts. The use of the term can be dependent on the era: a vehicle that may have been considered a supercar at one time may not retain its superiority indefinitely. The term supercar may refer to factory-built, street-legal sports cars.[3] Some supercars include some of the features required for race cars, like the roll cage, [4] while other supercars are in general race cars with only the minimum legal required modifications made (e.g. meeting emission regulations, legal tires, limited exhaust note) to be street legal.
Because clutches use changes in friction to modulate the transfer of torque between engine and transmission, they are subject to wear in everyday use. A very good clutch, when used by an expert driver, can last hundreds of thousands of miles. Weak clutches, abrupt downshifting, inexperienced drivers, and aggressive driving can lead to more frequent repair or replacement.
Manual transmissions are lubricated with gear oil or engine oil in some cars, which must be changed periodically in some cars, although not as frequently as the automatic transmission fluid in a vehicle so equipped. (Some manufacturers specify that changing the gear oil is never necessary except after transmission work or to rectify a leak.)
Gear oil has a characteristic aroma due to the addition of molybdenum disulfide compounds. These compounds are used to reduce the high sliding friction by the helical gear cut of the teeth (this cut eliminates the characteristic whine of straight cut spur gears). On motorcycles with "wet" clutches (clutch is bathed in engine oil), there is usually nothing separating the lower part of the engine from the transmission, so the same oil lubricates both the engine and transmission.
