Front-engine, Four-wheel-drive Layout
In automotive design, an F4, or front-engine, four-wheel drive (4WD) layout places the internal combustion engine at the front of the vehicle and drives all four roadwheels. This layout is typically chosen for better control on many surfaces, and is an important part of rally racing, as well as off-road driving. In terms of racing purposes, whether it be on-road or off-road, can be described as follows, A team that pursues the Weak LS4WD architecture will minimize the development cost of the front-wheel drive system at the expense of having a larger rear powertrain. The Weak architecture produces a vehicle with a large powersplit between the front and rear powertrains, while the Strong architecture recommends a vehicle with more similar power and torque requirements for the front and rear. Most four-wheel-drive layouts are front-engined and are derivatives of earlier front-engine, rear-wheel drive, or front-engine, front-wheel drive designs. The first origins of it were int ...

Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel mak ...

Nissan Skyline GT-R
The is a sports car based on the Nissan Skyline range. The first cars named "Skyline GT-R" were produced between 1969 and 1972 under the model code KPGC10, and were successful in Japanese touring car racing events. This model was followed by a brief production run of second-generation cars, under model code KPGC110, in 1973. After a 16-year hiatus, the GT-R name was revived in 1989 as the BNR32 ("R32") Skyline GT-R. Group A specification versions of the R32 GT-R were used to win the Japanese Touring Car Championship for four years in a row. The R32 GT-R also had success in the Australian Touring Car Championship, with Jim Richards using it to win the championship in 1991 and Mark Skaife doing the same in 1992, until a regulation change excluded the GT-R in 1993. The technology and performance of the R32 GT-R prompted the Australian motoring publication ''Wheels'' to nickname the GT-R "Godzilla" in its July 1989 edition. ''Wheels'' then carried the name through all the gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Rover Series I
The Land Rover series I, II, and III (commonly referred to as ''series'' Land Rovers, to distinguish them from later models) are compact British off-road vehicles, produced by the Rover Company since 1948, and later by British Leyland. Though inspired by the World War II jeep, the Land Rover immediately distinguished itself from all other cars. From launch, it was the first mass-produced civilian four-wheel drive car with doors on it, and an available hard roof. Contrary to conventional car and truck chassis, it used a sturdier fully box-welded frame. Furthermore, due to post-war steel shortage, and aluminium surplus, Land Rovers received non-rusting aluminium alloy bodies, favouring their longevity. In 1992, Land Rover claimed that 70% of all the vehicles they had built were still in use. Most series models feature leaf-spring suspension with selectable two or four-wheel drive (4WD), however series I's produced between 1948 and mid-1951 had constant 4WD via a freewheel mec ...

Dodge Power Wagon
The Dodge Power Wagon is a four-wheel drive medium duty truck that was produced in various model series from 1945 to 1980 by Dodge.Press Kit: 2005 Dodge Ram Power Wagon - Legendary Dodge Ram Power Wagon Returns. Chrysler Corporation, DaimlerChrysler AG, Auburn Hills, Michigan, September 30, 2004 The Power Wagon name was revived for the 2005 model year as a four-wheel drive version of the Dodge Ram 2500. As a nameplate, "Power Wagon" continues as a special package of the four-wheel drive version of 3/4 ton Ram Trucks 2500 model. The original civilian version, commonly called the "flat fender" Power Wagon (FFPW) or "Military Type", was mechanically based on Dodge's 3/4-ton WC series of World War II military trucks. The Power Wagon was the first 4x4 medium duty truck produced by a major manufacturer in a civilian version. It represents a significant predecessor to the many modern four-wheel drive trucks in use today.Carroll, John. 4 X 4 Vehicles. United States: Chelsea House, 1998 ...
