Bugatti Strips a Veyron’s Aftermarket Mods to Save Chassis 8.100
Molsheim craftsmen reversed a decade of unauthorized modifications to return the bare-metal W16 roadster to its exact factory specification.
Chassis 8.100 spent more than a decade on the road before someone decided it needed fixing. Not mechanical repairs. The Bugatti Veyron Grand Sport Vitesse, built as a one-off with an unpainted polished aluminum body, returned to Molsheim loaded with aftermarket alterations its original engineers never authorized.
La Maison Pur Sang, the automaker’s in-house historical authentication and restoration division, stripped those modifications out entirely. The team rebuilt the car to match its factory delivery specification, a process that required verifying every component against original build sheets. For a vehicle that left the assembly line over ten years ago, the forensic work was extensive.
Bugatti established the program specifically for situations like this. As hypercars age and change hands through private sales or auction blocks, owners frequently alter them. La Maison Pur Sang certifies provenance and reverses non-original changes, ensuring the mechanical and aesthetic record survives ownership transitions. It is less a service department than an archival enforcement unit.
The bare metal finish on chassis 8.100 complicated the restoration. Painting a panel hides imperfections; polishing raw aluminum exposes them. Molsheim craftsmen originally milled the body from massive solid aluminum blocks, calculating light reflection angles across every surface curve before final shaping. Re-matching that factory finish after a decade of wear and unauthorized bodywork required returning to those same metallurgical tolerances.
Inside, the cabin pairs Carmine Red leather with exposed carbon fiber and polished metal hardware. No paint touches the exterior panels.
Mechanically, the Grand Sport Vitesse retains the 8.0-liter quad-turbocharged W16 engine. Output remains at 1,200 metric horsepower and 1,106 lb-ft of torque. When Bugatti introduced the Vitesse variant in 2012, it represented the final evolution of the Veyron platform before the Chiron replaced it in 2016, pushing top speed capabilities past 250 mph with the roof removed.

Bugatti declined to disclose the cost of the refurbishment or the identity of the buyer. The restored chassis now sits on the French Riviera.
