Here are the reasons why Audi abandoned Torsen: 1. Compromise on patent barriers: The patent for Torsen is held by a steering system manufacturer called JTEKT. 2. Compromise on emission regulations: Torsen, including the crown gear differential, is indeed not fuel-efficient, mainly due to transmission efficiency and weight. 3. Confidence in its own technology: With significant advancements in sensor technology and electronic control technology, Audi dared to make bold attempts.
