A British startup, Audacious Automotive, is breathing new life into the iconic Audi Quattro, transforming it into a supercharged V8 restomod. This project merges the timeless design of the original Quattro with the potent technology of the B7-generation Audi RS4, promising a thrilling driving experience.

Key Takeaways

A classic Audi Quattro is being transformed into a high-performance restomod.
It will feature a supercharged 4.2-liter V8 engine from the B7 RS4, producing over 600 horsepower.
The design draws inspiration from the rally-bred Group B S1 Quattro.
The build will retain a manual transmission.
The project comes with a significant price tag, starting at $466,000, excluding donor vehicles.

A Heart Transplant: The RS4 V8

The most significant change under the hood is the replacement of the original five-cylinder turbo engine with the 4.2-liter V8 from the B7 Audi RS4. This naturally aspirated engine, which originally produced 414 horsepower, will be further enhanced with a supercharger. Audacious Automotive is targeting an output of at least 600 horsepower, making this Quattro a formidable machine.

Adding to the driver-focused experience, the restomod will be equipped with a manual transmission, a nod to the engaging nature of classic performance cars.

S1-Inspired Aesthetics

Beyond the mechanical upgrades, the exterior of the Quattro is being dramatically restyled, taking cues from the legendary Group B S1 Quattro. The updated bodywork includes a revised front fascia with a distinctive bumper, a new black grille, and aggressive air intakes. Flared wheel arches at all four corners significantly enhance the car's road presence.

The rear of the car also receives a striking makeover, featuring a louvered rear window, a prominent rear wing, a unique diffuser, and dual exhaust tips. These design elements are not merely cosmetic; they are engineered to serve crucial cooling and aerodynamic functions.

Performance and Price

Audacious Automotive aims to make this restomod not only powerful but also agile. Despite the extensive modifications and the larger V8 engine, the new bodywork is designed to make the car at least 250 kg (551 lbs) lighter than a B7 RS4. This weight reduction, combined with the substantial power increase, suggests a car with exceptional acceleration and handling capabilities.

However, such a bespoke and high-performance build comes at a considerable cost. Interested buyers will need to allocate a minimum of $466,000 for the conversion, and this price does not include the cost of sourcing the necessary donor Audi Quattro and RS4 vehicles.
