Praga R1
The Praga R1 is a sportscar made by Czech car manufacturer Praga Racing. The cars raced on the Supercar Challenge and the Britcar Endurance Championship. Development The first Praga R1 was built in 2012. Official Praga testdriver Danny van Dongen drove the car for the first time on October 10, 2012. Production of the R1 began in March 2013. Racing history On 15 November 2012 the Supercar Challenge organisation in conjunction with Praga Racing and Radical Benelux launched a new racing class. The Supercar Challenge Superlights would feature four sub-classes, one for the Praga R1, one for the Radical SR8, one for the Radical SR3 and one for Group CN cars. 2013 The first race of the Superlights class was run at the Slovakia Ring. Praga Racing announced that they would enter 10 Praga R1's in the first round. Due to a strike in the Spanish customs division most of the wheels, produced by Spanish company Braid Wheels, did not arrive in time. Due to not having enough whee ...

Dutch Supercar Challenge
The Supercar Challenge is a motor racing series centered on the Benelux. A special feature is that touring cars, GTs and Sportscars can all participate on an equal basis within the same class, enabled by very open regulations. The championship was first held in 2001, after replacing the Supercar Cup. From 2001 to 2011 the championship was called the Dutch Supercar Challenge, but due to interest from drivers, teams and tracks outside the Netherlands the organisers decided to drop 'Dutch' from its name on 11 February 2012. Format and regulations A typical race weekend exists of the usual practice on Friday and Saturday, qualifying on Saturday and two races of 45 to 60 minutes with one pit stop of at least 60 seconds. One race is on Saturday and one Sunday. The four classes usually run separate races two classes at a time. The two fastest run together and the two slowest run their race separate. The exception is at Spa-Francorchamps where all four classes can and do run together in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ben Collins (racing Driver)
Ben Lievesley Collins (born 13 February 1975) is a racing driver from Bristol, England. He has competed in motor racing since 1994 in many categories, from Formula Three and Indy Lights to sportscars, GT racing and stock cars. Collins was placed second in the Marlboro Masters Formula 3 championship event in 2000. He set the pace at the 2001 Le Mans 24 hours race in his first season for approximately four hours during the rain at night. After winning the European Stock Car Championship in 2003 ASCAR stock car racing he was signed by PDM Racing to do selected rounds of the 2004 Indy Racing League, but the car never appeared. In 2005, he competed in the British GT Championship in a Porsche 996 GT3, winning races on the way before moving up to the FIA GT Series with Ascari where he led races and scored several pole positions.

Transaxle
A transaxle is a single mechanical device which combines the functions of an automobile's transmission, axle, and differential into one integrated assembly. It can be produced in both manual and automatic versions. Engine and drive at the same end Transaxles are nearly universal in all automobile configurations that have the engine placed at the same end of the car as the driven wheels: the front-engine/front-wheel-drive; rear-engine/rear-wheel-drive; and mid-engine/rear-wheel-drive arrangements. Many mid- and rear-engined vehicles use a transverse engine and transaxle, similar to a front-wheel-drive unit. Others use a longitudinal engine and transaxle like Ferrari's 1989 Mondial t which used a "T" arrangement with a longitudinal engine connected to a transverse transaxle. Front-wheel-drive versions of modern Audis, from the A4 upwards, along with their related marques from the Volkswagen Group (which share the same automobile layout) also use a similar layout, b ...

Semi-automatic Transmission
A semi-automatic transmission is a "theoretical" multiple-speed transmission where part of its operation is automated (typically the actuation of the clutch), but the driver's input would be required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were 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 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 servo, while still requiring the driver to manually shift gears. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequential 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 times 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 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 shifter. This restriction avoids accidentally selecting the wrong gear; however, it also prevents the driver from deliberately "skipping" gears. The use of dog clutches (rather than synchromesh) results in faster shift speeds than a conventional manual transmission. On a sequential ...

Hewland
Hewland is a British engineering company, founded in 1957 by Mike Hewland, which specialises in racing-car gearboxes. Hewland currently employ 130 people at their Maidenhead facility and have diversified into a variety of markets being particularly successful in electric vehicle transmission supply. Hewland are currently supplying into Formula 1, Formula E, DTM, LMP, RallyCross, Prototype and GT Sportscar. History Mike Hewland ran a small engineering business at Maidenhead in the UK with the speciality in gear cutting. In 1959, Bob Gibson-Jarvie, the Chief Mechanic of UDT Laystall racing team running Cooper F2 cars, sought help from Hewland as gearbox troubles were experienced. The result of this request came out as six successful gearboxes being designed and built in 1959, and Hewland was in the gearbox business. The first transaxle product, the Hewland Mk.I of 1960, was a minor modification of the Volkswagen Beetle 4 speed transaxle used upside-down with custom made differ ...

Mid-engined
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 compon ...

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" veh ...

Inline-4
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occurr ...

Renault F-Type Engine
F Renault engine (F for ''fonte'', French for cast iron) is an automotive internal combustion engine, four-stroke, inline-four engine bored directly into the iron block, water cooled, with overhead camshaft driven by a timing belt, and with an aluminum cylinder head, developed and produced by Renault in the early '80s, making its appearance on the Renault 9 and 11. This engine is available in petrol and diesel versions, with 8 or 16 valves. History In December 1982, the Renault Board proposed a new diesel engine with for the Renault 9. Known as "F8M", the new engine was designed by engineer George Douin and his team and broke with tradition by featuring no removable cylinder liners, thanks to advances in metals technology that significantly slow the wear of rubbing mechanical parts. The new 4- cylinder unit adopted an overhead camshaft driven by a toothed belt that also controls the diesel injection pump. A second belt rotates the alternator and water pump, while a vacuu ...
