Quattro is a four-wheel drive system developed by Audi, a German automobile manufacturer. Introduced in the early 1980s, it enhances vehicle traction and stability, especially in challenging weather conditions like rain or snow. This technology allows power to be distributed to all four wheels, improving handling and performance. The Quattro system has been a significant factor in Audi's success in motorsports, particularly in rally racing. Its innovative design has influenced many other automotive brands, making all-wheel drive more popular in various vehicle types, from sports cars to SUVs.
