who invented the first front wheel drive car
Front-wheel drive Experiments with front-wheel-drive cars date to the early days of the automobile. According to various sources, sometime between 1895 and 1898 Gräf & 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. In 1898, Latil, in France, devised a front-wheel-drive system for motorising horse-drawn carts.
