Audacious IV Restomod Combines Classic Audi Quattro Style With RS4 V8 Power

UK-based builder Audacious Automotive has introduced the Audacious IV, a restomod project that pairs classic Audi Ur-Quattro styling with mechanical foundations from a B7-generation Audi RS4. The vehicle utilizes donor parts from both models to create a custom car combining vintage rally aesthetics with modern engineering.

Powertrain and Performance Options

The build relies on the RS4's 4.2-liter V8 engine, chassis geometry, suspension, brakes, electronics, and six-speed manual transmission, with upgraded components designed to handle increased power outputs. According to the company, available configurations include:

• Standard V8 Tune: Produces 592 horsepower.
• Supercharged Tune: Utilizes a TSS supercharger to increase output to 740 horsepower.
• Development Powertrain: Audacious is currently developing a third option featuring a targeted 10,000-rpm redline, prioritizing throttle response and high-revving performance, which will be available with or without a supercharger.

The builder reports that the vehicle can accelerate from zero to 60 mph in 3.4 seconds and reach a top speed of 200 mph, though specific engine upgrade details were not fully disclosed.

Interior Design and Production Details

The cabin features a retro-inspired design incorporating recognizable RS4 components such as the steering wheel and instrument gauge dials, with custom interior options available for buyers.

Production is planned for a limited run of 50 units, split between 40 full carbon fiber models and 10 metal-finished variants. The starting price is reported at £350,000, with an estimated build time of three years from start to delivery. Buyers are required to supply both donor vehicles for the conversion process.
