Two Ducati model names pointing to new Bentley-linked Diavels have appeared in California Air Resources Board (CARB) filings in the United States: “Ducati Diavel For Bentley” and “Ducati Diavel For Bentley Mulliner”. The same filing also includes the standard Diavel and Diavel S. It does not, however, explain how either Bentley-related version would differ from those existing models.

The paperwork is limited to environmental compliance, emissions and climate-risk information. It provides no details on power, equipment, styling or production numbers. The filings therefore establish that the two names appear in the CARB process, but not the motorcycles’ complete technical or commercial specification.

Why Mulliner matters

Mulliner is Bentley’s in-house bespoke division, responsible for highly personalised vehicles ranging from one-off projects to limited-run models. Its inclusion in one of the Ducati names suggests a more exclusive treatment may be involved, but the filing does not confirm any particular visual, mechanical or production change.

Ducati has already used the Diavel name for collaborations with car makers. In 2013, it worked with Mercedes’ high-performance subsidiary on the Diavel Carbon AMG, produced as a 743-unit limited run. The later Diavel 1260 Lamborghini was built in a worldwide run of just over 600 units. It was the last limited-edition V-twin Diavel before the family moved to the V4 platform in late 2022.

There is also a direct Ducati-Bentley precedent. During Art Basel week in Miami Beach in 2023, the companies revealed the Diavel V4 special edition Diavel for Bentley. Its design drew inspiration from Bentley’s Batur, based on the Continental GT. No official unveiling date is currently known for the two names listed in the CARB filing.
