Mercedes-Benz CLR
The Mercedes-Benz CLR was a Sports prototype, prototype race car developed by Mercedes-Benz in collaboration with in-house car tuning, tuning division Mercedes-AMG, AMG and motorsports specialists HWA Team, HWA GmbH. Designed to meet Le Mans Prototype, Le Mans Grand Touring Prototype (LMGTP) regulations, the CLRs were intended to compete in sports car racing, sports car events during 1999, most notably at the 24 Hours of Le Mans which Mercedes had last won in . It was the third iteration in Mercedes' 1990s sports cars, succeeding the Mercedes-Benz CLK LM, which in turn was born of the Mercedes-Benz CLK GTR, CLK GTR. Similar to its predecessors, CLR retained elements of Mercedes-Benz's production cars, including a V8 engine loosely based on the Mercedes-Benz M119 engine, Mercedes M119 as well as a front fascia, headlamps, and grille inspired by the then new Mercedes flagship Mercedes-Benz C215, CL Class. Three CLRs were entered for Le Mans in 1999 after the team performed nearly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1999 24 Hours Of Le Mans
The 1999 24 Hours of Le Mans was the 67th 24 Hours of Le Mans, and took place on 12 and 13 June 1999. The race had a large number of entries in the fastest Le Mans Prototype classes, with Audi, BMW, Ferrari, Lola Cars, Mercedes-Benz, Nissan, Panoz, Riley & Scott, and Toyota all represented. The BMW V12 LMR of Yannick Dalmas, Pierluigi Martini, and Joachim Winkelhock won overall, with their car's reliability and fuel economy allowing them to beat their faster rivals. Pre-race 1999 saw another increase in manufacturers involvement. Although Porsche did not send a team to contest in the prototype classes, Toyota retained their three updated Toyota GT-One, GT-Ones, now moved to the LMGTP class due to the demise of GT1, while Mercedes-Benz debuted three new Mercedes-Benz CLR, CLR LMGTPs. Nissan instead moved from GT1 to an open cockpit LMP, as did Panoz. Newcomer Audi attempted to try their hand at both classes, with two open cockpit Audi R8R, R8Rs and two closed cockpit Audi R ...

Double Wishbone Suspension
A double wishbone suspension is an independent suspension design for automobiles using two (occasionally parallel) wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff ( mechanical abrasion), and more. Implementation The double-wishbone suspension can also be referred to as "double A-arms", though the arms themselves can be A-shaped or L-shaped. A single wishbone or A-arm can also be used in various other suspension types, such as variations of the MacPherson strut. The upper arm is usually shorter to induce negative camber as the suspension jounces (rises), and often this arrangement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HWA Team
HWA Team, also known as HWA RACELAB, is the auto racing team of HWA AG, a German company based in Affalterbach, that also develops and builds vehicles and components for Mercedes-AMG race cars. It is named after founder Hans-Werner Aufrecht. History HWA was responsible for managing the AMG Mercedes team in the Deutsche Tourenwagen Masters (DTM). HWA AG was founded in 1999, and takes its name from Hans-Werner Aufrecht, who established AMG in 1967. Towards the end of 1998 Aufrecht sold a majority interest in AMG to DaimlerChrysler AG. As part of the process, the motor racing department and parts of the customised vehicles construction business were spun off and transferred to HWA AG. Between 1998 and 1999, HWA carried out the production of the Mercedes Benz CLK-GTR Straßenversion, building 20 cars with a further six roadster models built from spare parts in 2002. It was announced on 9 May 2018 that HWA would join Formula E for the 2018-19 season. Their drivers were to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Car Tuning
Car tuning is the modification of a car to optimise it for a different set of performance requirements from those it was originally designed to meet. Most commonly this is higher engine performance and dynamic handling characteristics but cars may also be altered to provide better fuel economy, or smoother response. The goal when tuning is the improvement of a vehicle's overall performance in response to the user's needs. Often, tuning is done at the expense of emissions performance, component reliability and occupant comfort. As a culture has grown around modified cars the term tuning has grown to encompass the cosmetic and stylistic changes owners make to personalize their vehicles. These changes can range from functional modifications designed to improve the performance or functionality of the car, to visual modifications which alter the aesthetics of the car and, in the case of certain mods, sometimes be detrimental to the performance or functionality of the car.

Sports Prototype
A sports prototype, sometimes referred to simply as a prototype, is a type of Auto racing, race car that is used in high-level categories of sports car racing. They are purpose-built auto-sports race cars, as opposed to production-car based or street-legal, low-volume Homologation (motorsport), homologation specials – thus entirely not intended for consumer purchase, or production beyond the fabrication of the (nearly) unique cars entered into races and in race-car competition classes or "formulas", with sufficiently open regulations to allow for vehicles of unique design to partake. 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 Homologation (motorsport), homologated sports cars. Current Automobile Club de l'Ouest, ACO regulations allow most sports car series to use two forms of cars: ''grand tourers (GT cars)'', which are strictly based on production street ca ...

Mercedes-Benz CLK LM
The Mercedes-Benz CLK LM (chassis code C298) was a Group GT1 sports car designed and built by Mercedes-Benz in partnership with AMG to compete in the FIA GT Championship. To satisfy the requirements of competing in the FIA GT Championship, a road-legal version had to be built to homologate the car. That car was known as the Mercedes-Benz CLK LM Straßenversion, and Mercedes-Benz assembled two chassis, one of which was destroyed for crash-testing. The CLK LM went on to win every single championship event in the 1998 FIA GT season, retiring only at the 1998 24 Hours of Le Mans, which was a non-championship event. The removal of the GT1 class from the FIA GT Championship due to the lack of entrants and rising costs meant that Mercedes' GT1 program was brought to a close at the end of 1998. Mercedes instead focussed their efforts on the newly introduced LMGTP class for the 1999 season, which produced the Mercedes-Benz CLR. Background Mercedes was left without a series to race i ...

Bridgestone
is a Japanese multinational manufacturing company founded in 1931 by Shojiro Ishibashi (18891976) in the city of Kurume, Fukuoka Prefecture, Fukuoka, Japan. The name Bridgestone comes from a calque translation and transposition of (), meaning 'stone bridge' in Japanese. It primarily manufactures tires, as well as golf equipment. As of 2021, Bridgestone is the largest manufacturer of tires in the world, followed by Michelin, Goodyear Tire and Rubber Company, Goodyear, Continental AG, Continental, and Pirelli.

Mobil 1
Mobil 1 is a brand of synthetic motor oil and other automotive lubrication products. Originally developed by the Mobil oil company, it is now globally marketed and sold by ExxonMobil. Mobil 1 engine oil was introduced in 1973. The brand range now includes a variety of engine oils, oil filters, chassis grease, transmission fluids, and gear lubricants. In 1998, Mobil challenged Castrol over the discovery that Castrol was processing conventional oil and calling it synthetic. At the time, Mobil 1 was still created using a true synthetic basestock, which is more expensive. Mobil lost the advertising "complaint", and, as a result, the definition of 'synthetic oil' including Group III heavily refined to the point of considering it synthetic. In response, Mobil allegedly downgraded their process to the less expensive process. ''Lubes N' Greases'' magazine reported shortcomings in the ability to pass the tests that the original Mobil 1 formula was able to. Relationship with automobil ...

Semi-automatic Transmission
A semi-automatic transmission is a multiple-speed Transmission (mechanics), transmission where part of its operation is Automation, automated (typically the actuation of the clutch), but the driver's input is still required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were almost exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and Epicyclic gearing, planetary gearsets. Names for specific types of semi-automatic transmissions include ''clutchless manual'', ''auto-manual'', ''auto-clutch manual'', and ''paddle-shift'' transmissions. These systems facilitate gear shifts for the driver by operating the clutch system automatically, usually via switches that trigger an actuator or servomechanism, servo, ...

Xtrac
Xtrac Limited, also known as Xtrac Transmission Technology, is a British engineering company founded in 1984 by the former Hewland engineer Mike Endean to make 4WD systems and gearboxes for rallycross and later rally and racing cars. Endean, together with Chris Goddard, who had been working on the electronic components essential to the system, in 1983 developed the first Xtrac 4WD system, for Norwegian rallycross star Martin Schanche. Schanche had thought up the idea of a changeable hydraulic 4WD system (his 1984 ERC winning Ford Escort Mk3 Xtrac- Zakspeed had a stepless FWD:RWD ratio of 28:72 to 50:50) and financed its development. This 560bhp so-called ''Xtrac No. 1'' was bought by Endean, in the mid-1990s, who raced it himself for many a year in carsprints and hillclimbs. "Xtrac started making gearboxes in the mid to late 1980s for the then-new Group A rally cars from their original premises in Wokingham and then continued to do so after moving in 1986 to a new 20,000 s ...

Mid Engine
In automotive engineering, a mid-engine layout describes the placement of an automobile engine in front of the rear-wheel axles, but behind the front axle. History The mid-engine, rear-wheel-drive format can be considered the original layout of automobiles. A 1901 Autocar was the first gasoline-powered automobile to use a drive shaft and placed the engine under the seat. This pioneering vehicle is now in the collection of the Smithsonian Institution. Benefits Mounting the engine in the middle instead of the front of the vehicle puts more weight over the rear tires, so they have more traction and provide more assistance to the front tires in braking the vehicle, with less chance of rear-wheel lockup and less chance of a skid or spin out. If the mid-engine vehicle is also rear-drive the added weight on the rear tires can also improve acceleration on slippery surfaces, providing much of the benefit of all-wheel-drive without the added weight and expense of all-wheel-drive compo ...

Naturally-aspirated
A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a turbocharger or a supercharger. Description In a naturally aspirated engine, air for combustion ( Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre during the intake stroke. Owing to innate restriction in the engine's inlet tract, which includes the intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric efficiency of less than 100 percent—and a less than complete air charge in the cylinder. The density of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
