BUGATTI REFUSED TO SELL US THE FINAL PART SO WE MADE IT

Product and Rebuild Summary

The video follows the rebuild of a crash-damaged Bugatti Chiron Pure Sport, converted into a one-off “Venom” appearance. It is a repair and road-test update rather than a completed performance review: the planned 200 mph run never happens because the engine develops misfires under heavy acceleration.

Main Features and Work Completed

• Custom windshield: Bugatti and other suppliers would not provide the required screen, so the team 3D-scanned the car and commissioned a custom laminated windshield and roof glass. The glass reportedly cost Alex $40,000. It fit on the first attempt, despite the team estimating only a 25% chance of success.
• Exterior and protection: The car was fully painted, fitted with body-kit parts and silver-painted accents, and covered in paint protection film (PPF). The PPF installers called it one of the hardest cars they had worked on.
• Interior: Bronze trim was changed to gloss silver using wrap and painted pieces, avoiding removal of the dashboard. Purple-and-white trimmed parts and the remaining interior components were fitted after the glass was installed.
• Cooling fan repair: A faulty fan was causing one cooling fan to run continuously. The replacement fan was sourced from an Audi A3, and the original Bugatti fan blades were transferred onto it.
• Electrical fault: A transmission warning was traced to a broken wire at the all-wheel-drive/Haldex control unit. Repairing the wire cleared the warning, but did not resolve the separate engine misfire.
• Remaining compromises: Some seals and trim still needed attention, and the middle undertray was missing. The team acknowledged that the car was not—and might never be—equivalent to a factory Bugatti rebuild.

User Experience and Performance

The initial road test felt good when the car was driven gently. However, applying full throttle caused the engine light to flash and the car to lose power or enter limp mode. Diagnostic checks showed recurring misfires, particularly on cylinders 3 and 11, with cylinder 4 appearing later.

Swapping a coil pack did not move the misfire, so the fault remained unresolved. A possible head-gasket problem was raised but not confirmed.

The car had driven well during an earlier test before final assembly, making the new fault confusing. The planned attempt to exceed 200 mph was postponed; the video ends while the car is still being investigated and partly disassembled.

Pros

• The custom windshield and roof glass fit on the first try.
• The finished exterior and silver-accented interior were praised for their appearance.
• The PPF was said to make the paint color stand out and protect it from stone chips.
• The team found workable alternatives for unavailable parts, including the fan and the damaged wiring.

Cons and Risks

• Bugatti refused to supply parts, citing safety concerns.
• The custom glass was expensive, and several parts, seals, and trim pieces remained imperfect or missing.
• The car still had an unresolved, potentially serious engine fault under boost.
• No high-speed testing was completed, so the rebuild’s performance and safety at 200 mph were not demonstrated.

Comparisons and Ratings

• The replacement fan came from an Audi A3, with the Chiron’s original fan blades adapted to it.
• The team compared the build with a factory repair, noting that they lacked Bugatti’s parts and development process.
• No formal product rating or score was given.

Overall Verdict

The rebuild shows impressive resourcefulness, especially in producing a custom windshield and adapting parts when Bugatti would not supply them. Visually, the car came together far better than the team initially expected.

However, it was not ready to recommend as finished or safe for high-speed use. The misfires under heavy load remained unexplained, and the planned 200 mph run did not take place.

Different Speakers’ Views

• Mat and the rebuild team: Proud of the car’s appearance and the solutions they fabricated, while openly accepting that it was not a perfect factory-standard repair.
• Bugatti’s stated position: The company did not support the repair because it considered the work unsafe.
• Alex: Was excited by the finished look but agreed that solving the fault and ensuring the car worked properly mattered more than attempting the speed run.
• External specialist Rick: Suggested checking the all-wheel-drive/Haldex system and noted that electrical grounding issues can cause problems on related vehicles.
