Renault 25
The Renault 25 is an executive car produced by the France, French automotive industry, automaker Renault from 1983 to 1992. The 25 was Renault's Flagship#Automotive, flagship, the most expensive, prestigious, and the largest vehicle in the company's line up. It placed second in the 1985 European Car of the Year rankings. In total, 780,976 units were built from 1983 until 1992. All 25s were built in Sandouville Renault Factory, Sandouville, near Le Havre, France. Introduction Introduced at the end of 1983 for a March 1984 start of sales, the Renault 25 was a large step forward in nearly every aspect from the Renault 20/30, Renault 20 / Renault 30 range it was replacing. Its five-door liftback body was penned by designers Gaston Juchet and Robert Opron of Citroën SM fame, and the unconventional style (the wraparound rear window - one of Opron's signature design features was used on many of his earlier designs such as the SM, the Renault Fuego and Renault 9 and 11, Renault ...

Renault R25
The Renault R25 was the Formula One car entered by Renault in the 2005 season. The chassis was designed by Bob Bell, James Allison, Tim Densham and Dino Toso with Pat Symonds overseeing the design and production of the car as executive director of Engineering and Bernard Dudot leading the engine design. The car won both the Drivers' and Constructors' Championships in 2005, the first titles for any car racing with a French licence since the Matra MS80's triumph in the 1969 season. It also secured the first championship titles for a Formula One car racing with a Renault engine since the Williams FW19 in . History During the season, the car turned out to be slower than the McLaren MP4-20 at numerous points, with the win tally being 8–10. Reliability and consistency prevailed in the end, with Fernando Alonso and Giancarlo Fisichella taking the car to the last win and titles for a V10 powered Formula One car, marking the end of an era. This car also claimed Michelin's fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1990 Renault 25 Baccara Sedan (28763654886)
Year 199 ( CXCIX) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was sometimes known as year 952 '' Ab urbe condita''. The denomination 199 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Understeer
Understeer and oversteer are vehicle dynamics terms used to describe the sensitivity of a vehicle to steering. Oversteer is what occurs when a car turns (steers) by more than the amount commanded by the driver. Conversely, understeer is what occurs when a car steers less than the amount commanded by the driver. Automotive engineers define understeer and oversteer based on changes in steering angle associated with changes in lateral acceleration over a sequence of steady-state circular turning tests. Car and motorsport enthusiasts often use the terminology more generally in magazines and blogs to describe vehicle response to steering in a variety of maneuvers. Vehicle dynamics terminology Standard terminology used to describe understeer and oversteer are defined by the Society of Automotive Engineers (SAE) in document J670SAE International Surface Vehicle Recommended Practice, "Vehicle Dynamics Terminology", SAE Standard J670, Rev. 2008-01-24 and by the International Organizatio ...

Douvrin Engine
The Douvrin family was an all-aluminum inline-four automobile engine designed in the early 1970s and produced from 1977 to 1996 by ''Compagnie Française de Mécanique'', a joint-venture between PSA and Renault located in the town of Douvrin in northern France. This engine is designed by the engineer Jean-Jacques His (father of Formula 1 engines from Renault and Ferrari). It was produced in the same factory as the ''PRV'' V6, which also is sometimes known outside France as the "Douvrin" V6. The Douvrin engine is also referred to as the ZDJ/ZEJ engine by Peugeot, and as the J-type engine by Renault. Construction This engine had an aluminium alloy block with cast iron liners, and an aluminium alloy head with one overhead camshaft driven by belt. Its displacement varied from 1995 to 2165 cc. This engine should not be confused with the PSA-Renault X-Type engine whose displacement varied from 954 to 1360 cc and had a gearbox integrated to the block. The Douvrin engine on the contrary, ...

Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, 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. History Prior to the invention of the turbocharger, |
V6 Engine
A V6 engine is a six-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. The first V6 engines were designed and produced independently by Marmon Motor Car Company, Deutz Gasmotoren Fabrik and Delahaye. Engines built after World War II include the Lancia V6 engine in 1950 for the Lancia Aurelia, and the Buick V6 engine in 1962 for the Buick Special. The V6 layout has become the most common layout for six-cylinder automotive engines. Design Due to their short length, V6 engines are often used as the larger engine option for vehicles which are otherwise produced with inline-four engines, especially in transverse engine vehicles. A downside for luxury cars is that V6 engines produce more vibrations than straight-six engines. Some sports cars use flat-six engines instead of V6 engines, due to their lower centre of gravity (which improves the handling). The displacement of modern V6 engines is typically between , t ...

Front-wheel Drive
Front-wheel drive (FWD) is a form of engine and transmission layout used in motor vehicles, where the engine drives the front wheels only. Most modern front-wheel drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel drive and four-wheel drive vehicles. Location of engine and transmission By far the most common layout for a front-wheel drive car is with the engine and transmission at the front of the car, mounted transversely. Other layouts of front-wheel drive that have been occasionally produced are a front-engine mounted longitudinally, a mid-engine layout and a rear-engine layout. History Prior to 1900 Experiments with front-wheel drive cars date to the early days of the automobile. The world's first self-propelled vehicle, Nicolas-Joseph Cugnot's 1769/1770 "fardier à vapeur", was a front-wheel driven three-wheeled steam-tractor. It then took at least a century, for the first e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Economy In Automobiles
The fuel economy of an automobile relates distance traveled by a vehicle and the amount of fuel consumed. Consumption can be expressed in terms of volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses ( wind resistance, tire drag, and others) encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers such as sudden acceler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drag Coefficient
In fluid dynamics, the drag coefficient (commonly denoted as: c_\mathrm, c_x or c_) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particular surface area. The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag. The drag coefficient of a lifting airfoil or hydrofoil also includes the effects of lift-induced drag. The drag coefficient of a complete structure such as an aircraft also includes the effects of interference drag. Definition The drag coefficient c_\mathrm d is defined as c_\mathrm d = \dfrac where: * F_\mathrm d is the drag force, which is by definition the force component in the direction of the flow velo ...

Notchback
A notchback is a design of a car with the rearmost section that is distinct from the passenger compartment and where the back of the passenger compartment is at an angle to the top of what is typically the rear baggage compartment. Notchback cars have "a trunk whose lid forms a distinct deck." In profile view, the body has a step down from the roof with a downward inclined passenger compartment's rear window to meet an almost horizontal trunk lid extending to the rear of the car. The category may be characterized as having a three-box design where the trunk volume is less pronounced than the engine and passenger compartments. Many models of sedans, coupés, or hatchbacks could be classified as notchbacks. However, the category has limited salience outside of American car manufacturers distinguishing the three-box models from other body styles in the same model range. For example, the Chevrolet Vega range included both a notchback coupe and a fastback coupe. North America One ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renault 9 And 11
The Renault 9 and Renault 11 are small family cars produced by the French manufacturer Renault for model years 1981–1988 in saloon (Renault 9) and hatchback (Renault 11) configurations — both were styled by the French automobile designer, Robert Opron. Variants were manufactured by American Motors Corporation (AMC), as the Renault Alliance and Renault Encore for the North American market. The car was produced in Turkey until 2000. The models use a transverse front-wheel drive engine configuration, and feature four wheel independent suspension. They were chosen as the European Car of the Year in 1982, as well as the Car of the Year by ''Motor Trend'' and one of the 10Best by ''Car and Driver'' in 1983. Phases There were three facelifts given to the Renault 9, two facelifts to the Renault 11, during its career. The Renault 11 that was released in 1983 was introduced with double headlights, which was different from the Renault 9. In 1985 the Renault 9 was given a face ...

Renault Fuego
The Renault Fuego (''Fire'' in Spanish) is a sport hatchback that was manufactured and marketed by Renault from 1980 to 1986, replacing the Renault 15 and 17 coupés of the 1970s. Marketed in the United States by American Motors Corporation (AMC), the Fuego was also assembled in several countries in South America, where production continued until 1992. According to Renault, 265,367 Fuegos were produced, 85% of those manufactured in France from February 1980 to October 1985. Spanish production for European markets continued into 1986. Design The Fuego's exterior was styled by Michel Jardin, and the interior by Francois Lampreia, both working under direction of Robert Opron. Noted automotive journalist, L. J. K. Setright said the Fuego "is blessed with a body which is not only roomy and aerodynamically efficient, but is also beautiful". The Fuego was heavily based on the Renault 18, sharing its floorpan and drivetrain, with its front suspension developed from the larger Ren ...
