RUF is a German automotive brand renowned for its in-depth modifications of Porsche models. The brand was founded in 1939 by Alois Ruf Senior and initially started as a car repair shop. During the economic crisis in the 1950s, RUF began to venture into the modification business and gradually became a pioneer in modifying Porsches. RUF not only offers performance enhancements but also reconstructs chassis and engages in lightweight design. Its products include models such as the RUF CTR 3, RUF RT, and RUF XL, all of which are modified based on Porsche models. In 1977, RUF introduced its first modified Porsche 911 model, and in 1981, it received a certificate of automobile manufacturing from the German Federal Motor Transport Authority. The emblem of RUF is distinctive, symbolizing freedom and speed. In 2011, RUF officially entered the Chinese market, selling its modified models through import. With its exquisite craftsmanship and excellent performance, RUF has gained a certain level of fame and influence worldwide.
