AUDACIOUS IV
a new chapter in analogue performance.
A contemporary interpretation of the UR quattro, brought to life through genuine engineering architecture, individual coachbuilding and an uncompromising mechanical philosophy.
Limited to fifty individual commissions worldwide.

The original inspires us. It does not define us.
what if the analogue era never ended?
The ultimate machine.
Audacious IV begins with the legendary quattro - one of the most emotionally charged silhouettes in rally history. The significance was never only the shape, however. It was the idea beneath it: traction, confidence, mechanical clarity and the ability to cover ground with extraordinary composure.
Audacious IV unites two points in the same engineering lineage: the rally born origin and the analogue road car evolution.
The result is a coherent vehicle programme developed from structure outward - a continuation of what mattered, created to make a historic idea feel alive again through modern technical depth, analogue character and hand built execution.
Memory and engineering.
Silhouette and structure.
Historic influence and modern mechanical depth.
two expressions
HAND FORMED METAL commissions retain and develop the genuine original UR quattro upper structure, roof and glazing, with new steel and aluminium bodywork crafted around the complete Audacious IV engineering foundation.
CARBON FIBRE commissions take the same Audacious IV engineering architecture in a different direction, with an entirely new carbon fibre upper body and newly engineered glazing. Carbon commissions do not require an original UR quattro source vehicle.
Both approaches share the same core philosophy: the body is not decoration. It is the visible expression of structure, stance, cooling, material and intent.
Architecture
& Integration
Developed around structural rigidity and lightness, this is where the driving experience begins.
Every Audacious IV begins with the complete structural, mechanical, electrical and control architecture of the B7 RS4. Floor and lower body structure, suspension geometry, drivetrain, braking, steering, electrical systems, control systems and principal hard points remain part of one coherent factory engineered foundation.
This is deliberate. Audacious begins with one complete performance architecture, bringing together an engine, gearbox and suspension originally engineered to work as an integrated system. That coherence provides the foundation for the entire automobile.
From there, the automobile is comprehensively reworked around a different purpose. Structure and packaging are integrated into IV proportions; body, cooling, material, glazing, suspension character, mechanical specification, interior and every visible point of identity are resolved as one commissioned work.
Mechanical
Character
At the heart of Audacious IV is a 4.2 litre V8, 6 speed manual transmission and Torsen all wheel drive architecture.
The result is a pure, modern yet mechanical driving experience.
Physical, analogue and deeply involving.
One architecture. Four commissioned engine programmes:
600BHP Stage One Supercharged
Baseline mechanical expression of Audacious IV.
750BHP Stage Two Supercharged
A higher output commissioned specification with expanded engine internal, cooling, fuelling and driveline development.
10,000RPM Naturally Aspirated
A bespoke high speed engine programme with dedicated engineering, manufacture and testing.
10,000RPM Supercharged
The most ambitious expression of Audacious IV, combining extreme engine speed with forced induction.
From The Big Picture
To The Smallest Detail
Audacious IV is limited to no more than 50 individual commissions worldwide.
No two will ever be the same. Each shares the same fundamental engineering architecture, while body construction, exterior detail, material, interior, suspension character, mechanical specification and intended use may be developed around its commissioner.
