Four roadsters, four commissions
Droptail is a four-car series on underpinnings developed only for it, not a Dawn derivative. Each car is a separate commission, so the factory file and the exact expression matter more than a generic model average.

Estimate band for good road cars. 0 documented sales since 2019 plotted below.
Band, axis and sale positions shown in recorded USD. USD editorial estimate across four individually commissioned cars. Their specifications are not interchangeable.
Instrument calibration for this file is in progress — the terminal above reads the documented record directly.
Empty ledger by design: reported commission prices are unattributed estimates, not verified public transactions.
Overview
Sweptail retained Phantom VII foundations and Boat Tail reconfigured the Architecture of Luxury. Droptail went further: Rolls-Royce developed a separate mixed-material monocoque and mounted a contemporary V12 drivetrain within it.
The company announced four expressions. La Rose Noire appeared first at Monterey in August 2023, followed by Amethyst in Gstaad and Arcadia in 2024. Each uses the same roadster idea as a starting point rather than a common trim package.
Rolls-Royce has not published prices for the commissions. Public estimates above $20 million are useful only as context; none is a documented resale.

HICON BID
A HICON Bid is a confidential expression of buying interest on the Rolls-Royce Droptail file — never public, never shown to other members. It is not a binding purchase, and HICONIUM holds no funds.

The vault
You keep one? The record starts in your garage — identity, papers, photography, and the market evidence this file already carries, bound to your chassis.
The value drivers
Two F40s can be indistinguishable in a photograph and a million apart at the hammer: the difference is never in the paint. Build the file below and watch the band move.

a good, honest road car — before its file is read
Spans are indicative, drawn from the documented sales cited beside each attribute. The calibrated multipliers — and how they compound for one specific chassis — are member instruments.
