Koenigsegg has built just over 100 cars since it began production out of a converted fighter jet hangar in 2003. Each car is hand-built to exacting specifications and excruciating detail at Koenigsegg’s factory in Ängelholm, Sweden. The One:1, pronounced as a ratio (“one-to-one”), is the company’s most radical accomplishment thus far. The strange name is representative of the nearly inconceivable 1:1 power to weight ratio. That’s 1341 hp (when running on E85) in a vehicle that weighs just 1360 kg with all fluids and a half tank of fuel. The One:1 will see its driver from 0 to 250 mph in just 20 seconds and can theoretically reach a 273 mph top speed – take it for a spin and try hitting that mark yourself. This rocket ship with wheels intends to set a new lap record at the Nürburgring once management at the famous racing venue allows lap records to be set again. With each of the six $2.4 million hypercars already sold, getting a hand on the wheel of this ultra-exotic in Forza Motorsport 6 is the closest the rest of us may ever get.
