This 1,360-HP Koenigsegg One:1 Is The ‘World’s First Megacar’

The ultra-powerful automotive marvel is expected to sell for $10 million or more.

Back in 2015, the term “hypercar” was coming into its own as the McLaren P1, Porsche 918, and Ferrari LaFerrari blitzed the automotive scene, previewing the performance potential of a road car injected with electric power. On the heels of its already extreme Agera platform, Koenigsegg leapfrogged everyone with the ingeniously marketed One:1, aka the “world’s first megacar.”

The name comes from its unprecedented 1:1 power-to-weight ratio—1,360 horsepower from a 1,360-kilogram (3,000-pound) road-legal car. The megacar billing comes from the output, which is equivalent to 1 megawatt of power produced entirely in a twin-turbocharged 5.0-liter V8—no hybridization needed. The resulting speed is staggering even a decade removed from its debut. The One:1 will hit 124 mph (200 kph) in 6.6 seconds, 186 mph (300 kph) in what was a world-record setting 11.92 seconds, and 249 mph (400 kph) in under 20 seconds on the way to a 273 mph top speed.

In addition to the feathery weight and then-unprecedented power, the One:1’s active aerodynamics, triplex damper technology, carbon fibre Aircore wheels, variable-geometry turbochargers, and an advanced seven-speed dual-clutch transmission made it one of the most advanced road cars ever. Because the car is exceptionally rare—only seven were produced, six being available for purchase—the One:1’s value has multiplied past its $2.85 million MSRP, with the most recent of very few aftermarket sales clocking in at over $10 million in 2025.

Expect this example, chassis No. 7108, to gavel for a similar price this July. It’s among the most photographed One:1s, thanks to a particularly stunning clear-coat carbon fiber and Kevlar exterior accented with contrasting flashes of “China Pink.” The cabin matches: black leather and Alcantara are combined with bespoke China Pink seat piping, stitching, door panels, rear bulkhead, and interior trim.

RM Sotheby’s has more on the car’s provenance:

Chassis 7108 was delivered new on 4 April 2015 via Esser Automotive, Koenigsegg’s long-standing German representative. Initially registered to a German company based in Hilden before later passing to Pace Cars International GmbH of Düsseldorf, a subsidiary of Esser Automotive, it has benefited from attentive ownership and specialist maintenance from new.

The One:1 returned to Esser Automotive for routine servicing in March 2017, January 2019, and February 2021. The car was then serviced by SIC Garage in July 2022 before returning to Esser Automotive again for a fresh service and factory updates prior to the Tegernsee Auction. At the time of cataloguing, the odometer displayed 4,233 kilometres from new.

Significantly, ownership of chassis 7108 grants access to Koenigsegg’s Ghost Squadron community—a private network of owners, whose activities include factory events, international driving tours, and some of the most exclusive automotive gatherings in the world.

Bidding is expected to end between $9,500,000 and $11,500,000, but what a collector will pay to own the world’s first megacar remains to be seen.
