Audacious IV blends Audi RS4 V8 with classic Ur-Quattro looks

UK firm Audacious Automotive has created the Audacious IV, built on a B7 Audi RS4 beneath Ur-Quattro-style bodywork. Its 4.2-litre V8 makes 592 hp, or 740 hp with an optional TSS supercharger, sent through a six-speed manual gearbox. The company says a 10,000-rpm version of the engine is also in development.
