(Redirected from Front wheel drive)
Front-wheel drive (or FF layout) is a form of engine/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.

Prior to 1900
According to various sources, sometime between 1895 and 1898 Gr?f & Stift built a voiturette with a one-cylinder De Dion-Bouton engine fitted in the front of the vehicle, powering the front axle. It was thus arguably the world's first front-wheel drive automobile, but it never saw mass production, with only one copy ever made.
19001920
Experiments with front-wheel drive cars date to the early days of the automobile. Following the Spanish-American War, J. Walter Christie of the USA was working on designs for a front-wheel drive car, which he promoted and demonstrated by racing at various speedways in the U.S., and even competed in the Vanderbilt Cup and the French Grand Prix. In 1912 he began manufacturing a line of wheeled fire engine tractors which used his front-wheel drive system, but due to lack of sales this venture failed.
19201930
The first successful application of front-wheel drive was the Miller 122 racecar designed in 1924 by Harry Arminius Miller of Menomonie, Wisconsin. However, the idea languished outside of the motor racing arena as no major auto manufacturer attempted the same for production automobiles. Market experiments in the United States were left to small endeavors such as the Ruxton (200 cars in 1929), and the Cord L-29 of 1929. Neither automobile maker was particularly successful on the open market. Alvis Cars of the United Kingdom also introduced a front-wheel drive model in 1928, but it was not a success either.
19301945
The first successful consumer application came in 1931 with the DKW F1 from Germany. Other German car producers followed: Stoewer offered a car with front wheel drive in 1931, Adler in 1932 and Audi in 1933. In 1934, the very successful Traction Avant cars were introduced by Citro?n of France. BSA three-wheelers of the United Kingdom were also popular front-wheel drive automobiles, and the Cord 810 of the United States managed a bit better in the late 1930s than its predecessor one decade earlier. These vehicles featured a layout that places the engine behind the transmission, running "backwards," (save for the Cord, which drove the transmission from the front of the engine). The basic front-wheel drive layout provides sharp turning, and better weight distribution creates "positive handling characteristics" due to its low polar inertia and relatively favourable weight distribution. (The heaviest component is near the centre of the car, making the main component of its moment of inertia relatively low). Another result of this design is a lengthened chassis.
19451960
Front-wheel drive was further popularized by the 1948 Citro?n 2CV,[citation needed] where the air-cooled lightweight aluminium flat twin engine was mounted ahead of the front wheels, but used Hookes type universal joint driveshaft joints, and 1955 Citro?n DS, featuring the mid-engine layout. Panhard of France, DKW of Germany and Saab of Sweden offered exclusively front-wheel drive cars, starting with the 1948 Saab 92.
In 1954, Alfa-Romeo had experimented with its first front-wheel drive compact car named "33" (not related or referred to sports car similarly named "33"). It had the same transverse-mounted, forward-motor layout as the modern front-wheel drive automobiles. It even resembled the smaller version of its popular Alfa Romeo Giulia. However, due to the financial difficulties in post-war Italy, the 33 never saw the production. Had Alfa-Romeo succeed in producing 33, it would precede the Mini as the first "modern" front-wheel drive compact car.
In 1959 Austin Mini was launched by the British Motor Corporation, designed by Alec Issigonis as a response to the first 'oil crisis', the 1956 Suez Crisis, and the boom in bubble cars that followed. It was the first production front wheel drive car with a watercooled inline four cylinder engine mounted transversely....(and so on) To get More information , you can visit some products about mitsubishi servo motor, go karts engines, .
