British tuner Audacious Automotive is reviving the iconic Audi Ur-Quattro, equipping it with a supercharged 4.2-liter V8 engine sourced from the RS4 to deliver over 600 horsepower. The new build features a lightweight steel-aluminum hybrid body (with production versions switching to full carbon fiber) and retains the original front-engine layout, ensuring excellent compatibility. Customers must supply their own Ur-Quattro and an RS4 as donor vehicles and pay approximately $470,000. Despite the steep price tag, the project has already demonstrated exceptional craftsmanship, and more than one unit is planned for production. Blending rally heritage with the roar of a V8, this reimagined classic is a dream come true for Audi enthusiasts.
