Ultra-Rare Koenigsegg One:1 May Bring Up to $10 Million at Auction
A highly sought-after Koenigsegg One:1 is preparing to cross the block at RM Sotheby’s Tegernsee sale on July 4, 2026. Auction specialists expect it to achieve somewhere between €8 million and €10 million, or roughly $9 million to $11.5 million.
Built in 2015, this is one of only six One:1 examples delivered to private buyers. The model holds a special place in Koenigsegg history and remains one of the standout hypercars of its era.
The Original Megacar
When the One:1 appeared at the 2014 Geneva Motor Show, the supercar world was focused on ever-higher speed figures. Koenigsegg took a broader approach, designing the car around an extraordinary power-to-weight balance.
Its twin-turbo 5.0-liter V8 produces 1,341 horsepower, while dry weight sits at just 2,998 pounds. The name One:1 reflects that near-perfect ratio, and the company also highlighted its output as one megawatt of power, which is why it called the car the first true “megacar.”
Even by today’s standards, the performance claims are astonishing. Period figures suggested a 0-249 mph run in about 20 seconds, and the car rode on tires approved for speeds up to 273 mph.
Beyond raw output, the One:1 introduced advanced hardware that helped define the car’s character. It featured active aerodynamics, Koenigsegg’s Triplex suspension, Aircore carbon-fiber wheels, variable-geometry turbochargers, and a seven-speed dual-clutch gearbox.
All of that engineering was aimed at creating a machine that could stay composed at extreme speeds while still delivering precision and control. In many ways, the One:1 pointed toward the direction future halo cars would eventually follow.
The JC-Labeled Example
The car heading to auction carries chassis number 7108 and is widely recognized among enthusiasts. Nicknamed “JC,” a reference visible on the engine cover, it is believed to have been the third One:1 delivered to a private customer.
Its exterior combines bare carbon fiber and Kevlar with a clear protective finish, then adds China Pink accents across the splitter, side skirts, side intakes, rear diffuser, and large rear wing.
The same color theme continues inside, where black leather and Alcantara are paired with pink stitching and trim details. Carbon-fiber bucket seats reinforce the car’s track-focused intent.
Well Kept and Barely Used
Originally delivered in April 2015 through German dealer Esser Automotive, the car has a documented ownership and maintenance history, including regular servicing by authorized specialists. At cataloging, its odometer showed only 2,630 miles.
In addition to its rarity and condition, the future owner will gain entry to Koenigsegg’s Ghost Squadron, an exclusive customer network that includes events, factory access, and private gatherings.
With just six customer cars built, the One:1 has long been regarded as one of the defining hypercars of the modern age. More than a fast machine, it represents a moment when Koenigsegg pushed the boundaries of automotive design and performance in a way few brands ever have.
Given the model’s status and the scarcity of examples on the market, this auction could easily attract intense bidding. For collectors, it is a rare chance to buy one of the most important Koenigseggs ever made without placing a new order and waiting for years.
