BMW M2
The BMW M2 is a high-performance version of the BMW 2 Series automobile developed by BMW's motorsport division, BMW M GmbH. As the 2 Series replaced the 1 Series coupé and convertible models, the first-generation M2 was marketed as the most basic M model in the range. The first-generation M2 used the F8x chassis from the M3/M4, codenamed F87 and featured the BMW N55 series engine, while its successors, the M2 Competition and M2 CS, featured a twin-turbocharged engine developed by BMW M GmbH (S55 engine). The second-generation M2 uses the CLAR platform, codenamed G87, which it shares with the G80 M3 and G82 M4. It features the BMW S58 twin-turbocharged inline-six engine, developed by BMW M GmbH. __TOC__ First generation (F87; 2016) BMW M2 Coupé The M2 was unveiled in '' Need for Speed'' in November 2015, before later premiering at the North American International Auto Show in January 2016.

BMW M
BMW M GmbH, formerly known as BMW Motorsport GmbH, is a subsidiary of BMW AG that manufactures high-performance luxury cars. BMW M ("M" for "motorsport") was initially created to facilitate BMW's racing program, which was very successful in the 1960s and 1970s. As time passed, BMW M began to supplement BMW's vehicle portfolio with specially modified higher trim models, for which they are now most known by the general public. These M-badged cars traditionally include modified engines, transmissions, suspensions, interior trims, aerodynamics, and exterior modifications to set them apart from their counterparts. All M models are tested and tuned at BMW's private facility at the Nürburgring racing circuit in Germany. BMW M also provides M packages for the BMW S1000RR motorcycle, with a limited-production homologation-special, race-type machine designated M1000RR, produced from 2021 onwards. History Origins Established in May 1972 with 35 employees, it grew to 400 employee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dual-clutch Transmission
A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission) is a type of multi-speed motor vehicle, vehicle Transmission (mechanics), transmission system, that uses two separate clutches for odd and even gear train, gear sets. The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit. In car and truck applications, the DCT functions as an automatic transmission, requiring no driver input to change gears. The first DCT to reach production was the ''Easidrive'' automatic transmission introduced on the Hillman_Minx#Audax_design_Hillman_Minx_(Series_I_to_Series_VI,_1956–1967), 1961 Hillman Minx mid-size car. This was followed by various eastern European tractors through the 1970s (using manual operation via a single clutch pedal), then the Porsche 962, Porsche 962 C racing car in 1985. The first DCT of the modern era was used in the 2003 Volkswagen Golf Mk4#R32 ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safety Car
In motorsport, a safety car, or a pace car, is a car that limits the speed of competing cars or motorcycles on a racetrack in the case of a ''caution period,'' such as an obstruction on the track or bad weather. The safety car aims to enable the clearance of any obstruction under safer conditions, especially for Motorsport marshal, marshals and/or awaiting more favourable track conditions weather-wise. By following the safety car, the competitors' tyres remain as close as possible to operating temperature while their engines do not overheat. A safety car is also preferred over stopping the race (Red flag (racing), red flag) and restarting, as the latter takes longer. During a caution period, the safety car (which is typically an appropriately modified high-performance production car) enters the track ahead of the leader. Depending on the regulations in effect, competitors are not normally allowed to pass the safety car or other competitors during a caution period, and the safety ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canadian English, Canada, British English, the United Kingdom and American English, the United States), or stick shift (in the United States), is a multi-speed motor vehicle Transmission (mechanical device), transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace, and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission. Common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic ...

Gudgeon Pins
In internal combustion engines, the gudgeon pin (English, wrist pin or piston pin US English) connects the piston to the connecting rod, and provides a bearing for the connecting rod to pivot upon as the piston moves.Nunney, Malcolm James (2007) "The Reciprocating Piston Petrol Engine: Gudgeon pins and their location" ''Light and heavy vehicle technology'' (4th ed.) Butterworth-Heinemann, Oxford, UKp. 28 In very early engine designs, including those driven by steam, and many very large stationary or marine engines, the gudgeon pin is located in a sliding crosshead that connects to the piston via a rod. A gudgeon is a pivot or journal. The origin of the word gudgeon is the Middle English word gojoun, which originated from the Middle French word goujon. Its first known use was in the 15th century.Webster's Seventh New Collegiate Dictionary, G & C Merriam Company, 1963, p. 370 Overview The gudgeon pin is typically a forged short hollow rod made of a steel alloy of high strength and ...

Piston
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder (engine), cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering Porting (engine)#Two-stroke porting, ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion piston engine, internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts dow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Connecting Rods
A connecting rod, also called a 'con rod', is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston. In its most common form, in an internal combustion engine, it allows pivoting on the piston end and rotation on the shaft end. The predecessor to the connecting rod is a mechanic linkage used by water mills to convert rotating motion of the water wheel into reciprocating motion. The most common usage of connecting rods is in internal combustion engines or on steam engines. __TOC__ Origins A connecting rod crank has been found in the Celtic Oppida at Paule in Brittany, dated to 69 BC. The predecessor to the connecting length is the mechanical linkage used by Roman-era watermills. An early example of this linkage has been found at the ...

Forged
Forging is a manufacturing process involving the shaping of metal using localized compression (physics), compressive forces. The blows are delivered with a hammer (often a power hammer) or a die (manufacturing), die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.Degarmo, p. 389 Forging has been done by metalsmith, smiths for millennia; the traditional products were kitchenware, household hardware, hardware, hand tools, edged weapons, cymbals, and jewellery. Since the Industrial Revolution, forged parts are widely used in mechanism (engineering), mechanisms and machines wherever a component requires high strength of materials, strength; such forgings usually require further processing (such as machining) ...

Straight-six Engine
A straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or fewer cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines gradually became more common in the 1970s and by the 2000s, V6 engines had replaced straight-six engines in most light automotive applications. Characteristics In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine, but longer than straight-four engines, V6s, and most V8s. Compared to V-configuration engines with similar power and displacement, the straight configuration has fewer injectors, a single head, and a single exhaust manifold, all contributing to better reliability and perfor ...

Turbocharger
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement. Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger.
