## The price and the proof

Indicative road-car band $4.5M–$8M · 1 documented road sales · 1 recorded sales on file. Modeled values are not observed sales. Nothing here is investment advice.

Confidence: estimate. Estimate anchored to Bonhams' documented CHF 4'600'000 sale at Bonmont in 2019 and the factory count of six customer cars plus one development car. The result is left out of the USD ledger because the importer forbids mixed currencies and no FX conversion is inserted as sale evidence.

Figures in USD. Public trading is exceptionally thin; chassis status, factory history, colour and legal market eligibility can outweigh broad model averages.

## The Agera reduced to a number

Koenigsegg revealed the One:1 in 2014 after removing roughly 100 kg from the Agera R and raising the twin-turbo V8 to one megawatt. Roof scoop, larger cooling exits, active underbody aero and a top-mounted rear wing made the package visibly separate from the road-biased Agera variants.

The factory quotes an approximate 20 seconds from zero to 400 km/h and about 10 seconds back to rest. A measured 0–300–0 km/h run in July 2015 took 17.95 seconds, improving Koenigsegg's prior Agera R figure by more than three seconds.

Production was six customer cars plus one factory development car. That distinction matters to provenance and explains why contemporary descriptions alternate between six built and seven examples.

| Highlight | Detail |
| --- | --- |
| The ratio uses curb weight | The name is not based on a dry shell. Koenigsegg quotes 1'360 kg with all fluids and half a tank of fuel against 1'360 hp on E85: one horsepower for each ready-to-drive kilogram. |
| A wing hung from above | The active rear wing mounts from its upper surface, leaving the lower working face uninterrupted. Active front underbody aero, longer venturi tunnels and ride-height control balance it across the speed range. |
| Six cars went to customers | Koenigsegg built six customer One:1s and retained one factory development car. The seven-car total often appears as either six or seven depending on whether the prototype is counted. |
