The KOENIGSEGG ONE:1 was unveiled at the 2014 Geneva Motor Show. KOENIGSEGG built six cars apart from the car presented at the Geneva Motor Show. KOENIGSEGG brought two cars to the 2014 Goodwood Festival of Speed, where it was displayed alongside other supercars such as the McLAREN P1™, the FERRARI LAFERRARI, the PORSCHE 918 Spyder, and the PAGANI HUAYRA.
The ONE:1 is capable of accelerating to 0–100 km/h (0–62 mph) in 2.8 seconds, 200 km/h (124 mph) in 6.6 seconds, 300 km/h (186 mph) in 11.9 seconds, and 322 km/h (200 mph) in 14.3 seconds.
The ONE:1 can reach a theoretical top speed of 280 mph (451 km/h), faster than the 273 mph AGERA R and the 275 mph AGERA RS.
The ONE:1 is called so because of its equal power-to-weight ratio (1 horsepower per 1 kilo). This gives the car the unique distinction of being the first megacar.
