Koenigsegg has unveiled the long anticipated One:1 supercar, which they call
"the world's first megacar". Its ratio between the horsepower and weight is 1:1,
hence the One:1 name.
The Swedish exotic car manufacturer hasn't released a 0-60 mph time for the One:1. Instead, they quote a 0 to 250 mph (400 km/h) time of approximately 20 seconds.
All six One:1's that will be manufactured have already found an owner. It was reported that the majority of them will go to wealthy Chinese businessmen, but two will remain in Europe.
The aerodynamic design incorporates many innovative features to keep the car as glued to the ground as possible. These include the use of track optimized aero winglets on the front bumper, extended venturi tunnels and side splitters, a Le-Mans inspired active wing configuration at the rear and an optimized active undertrim air management.
The Koenigsegg One:1 features a drag coefficient of 0.445-0.50, depending on the adaptable rear wing. The One:1 produces almost twice as much downforce as the Agera R. At 260 km/h, the One:1 produces 610 kg of downforce, while at 440 km/h, this number jumps to 830 kg. The One:1 pulls 2G in the corners on road legal tires.
V8 Engine with 1.8 Bar of Boost
The engine architecture is the same as on the Agera R, but upgraded for more power. The 5.0-liter V8 unit features two turbochargers and an increased boost pressure from 1.4 bar in the Agera R to 1.8 bar in the One:1.
The Koenigsegg One:1 has 1340 horsepower and 1011 lb-ft (1371 Nm) of torque. All this power is transferred to the rear wheels via a 7 speed dual-clutch transmission.
Koenigsegg's flex fuel philosophy is taken one step further as the One:1 now runs on E85 biofuel, Racefuel or normal petrol.
