Some other details seem to have changed since reports surfaced about the car in October. For one, the WSJ claims the car's weight will be 1,340 kilograms, which suggests that power might be lower than the 1,400 figure earlier reported if the 1:1 ratios hold true. WSJ also reports that Koenigsegg will produce 100 copies of the Agera One:1, a much higher number than the original estimate of six.
All will be clear come March 4, though, when the car is officially unveiled at the Geneva Motor Show. A sneak preview will also reportedly happen on February 26, which we'll do our best to crash to get you more details sooner.
And because we know you're wondering, the latest Bugatti Veyron Grand Sport Vitesse has one unit of horsepower for every 1.66 kilograms of weight.
