Why it matters
The One:1 made Koenigsegg’s engineering ambition visible in a particularly concentrated form. Its aerodynamic and weight-conscious development provides context for the subsequent Agera RS while retaining a separate identity.
Collector Profile: Seven-example one-megawatt programme
Koenigsegg One:1
The One:1 gave Koenigsegg’s Agera-based development a one-megawatt expression, pairing a stated one-to-one power-to-weight ratio with highly focused aerodynamics.
MarqueKoenigsegg
Era2014–2015
Collector contextSeven-example one-megawatt programme
Rarity & context
Koenigsegg lists seven examples built between 2014 and 2015. A buyer should establish the exact car’s role and factory history within that programme, including any development use and later work.
Collector perspective
The One:1 is included as a central Koenigsegg collector reference. Its appeal rests on precise identity and original configuration as much as on the headline power-to-weight relationship.
Distinguish an original One:1 from other Ageras with visually similar equipment. Aerodynamic components, carbon wheels, circuit history, repairs and specialist maintenance should be assessed against factory documentation.
Private Acquisition
Atelier Grand Slam considers buyer mandates relating to the Koenigsegg One:1. A mandate initiates a targeted search and does not imply that a specific example is currently available. Any potential acquisition remains subject to owner willingness, provenance and condition verification, legal and financial diligence, and mutually acceptable transaction terms.
