Audi RS6 Ferrari V12 GT3, the craziest RS6 build on the internet has begun
09/06/2026
This is not another widebody Audi RS6. This is something much more unhinged.
Swedish creator and builder Olle Olsson has revealed what may become one of the wildest RS6 projects ever attempted: a street-legal Audi RS6 C8 transformed into a rear-wheel-drive, GT3-inspired special powered by a Ferrari F12 V12 engine. Yes, that sentence is real.
The project is being described as the Audi RS6 Ferrari V12 GT3, or simply #AudiRS12. It will use a Ferrari F140-family V12, a motorsport-style six-speed Samsonas sequential gearbox, a completely reworked drivetrain layout and a bespoke body developed from scratch together with Swedish car designer Sebastian Simonsson.
An Audi RS6, but not as Audi intended
The base car is an Audi RS6 C8. Normally, that means quattro all-wheel drive, a twin-turbo V8, huge everyday usability and the kind of effortless speed that made the RS6 one of Europe’s ultimate performance estates. This project throws most of that logic out of the window.
Instead of keeping the factory formula, Olle wants to build a rear-wheel-drive GT3-inspired special with the soul of a Ferrari engine and the attitude of something Audi would never be allowed to put into production. That is the appeal. The RS6 has always been brutally capable.
Ferrari F12 V12 power in an RS6 body
The heart of the build is the famous Ferrari F140-family V12, sourced from the Ferrari F12 world. That engine is one of the great modern naturally aspirated V12s. High-revving, dramatic and known for the kind of sound that makes almost every turbocharged engine feel muted by comparison.
Olle specifically mentions the dream of building something around a Ferrari F12 Berlinetta V12 because of its character and its wild sound at around 8,900 rpm. But instead of putting that engine back into a Ferrari, the plan is more ambitious.
A custom billet bellhousing and clutch solution will be developed to connect the V12 to a motorsport six-speed sequential gearbox. From there, the entire driveline strategy needs to be rebuilt around a car that was never designed for this kind of layout.
Rear-wheel drive, GT3 inspiration and a one-off body
One of the most interesting parts is the design. Olle says this will be his first time designing and building a complete body from scratch, together with Sebastian Simonsson. The aim is to create a 1-of-1 street-legal GT3-style RS6, with a body that supports the new mechanical concept rather than simply decorating it.
Laser scanning of the body and components has already started, along with early driveline strategy work. That suggests the team is treating the project as a proper engineered build, not just a social-media render chasing attention. The final result should sit somewhere between DTM fantasy, GT3 race car and forbidden RS6 prototype.
AutoNext Take
An Audi RS6 C8 with a Ferrari F12 V12, rear-wheel drive, a sequential gearbox and a custom GT3-style body sounds like something that should remain trapped inside a late-night group chat.
The real challenge will be execution. Making it start is one thing. Making it drive properly, cool correctly, shift cleanly, pass legal requirements and feel like one coherent car is another level entirely.
