About the Koenigsegg One-1
Unveiled at the 2014 Geneva Motor Show, the One:1 is a track-focused evolution of the Agera, famously named for its equal ratio of 1,360 PS to 1,360 kg. It was the first production car to deliver one megawatt of power, utilizing a 5.0-litre V8 with 3D-printed variable geometry turbochargers. The car features advanced active aerodynamics, including a Le Mans-inspired top-mounted wing and a carbon fibre chassis 20% lighter than the standard Agera. With only six customer units and one prototype produced, it remains one of the most exclusive and technologically significant hypercars of the 21st century.
