Since its debut at the Geneva Motor Show earlier this year, Koenigsegg Agera One:1 was very rarely seen in public and no journalist was allowed behind the wheel. Now a the Goodwood Festival of Speed the Swedish car maker has brought not one but two One:1s, and they’ve even allowed a civilian to driver it!

These two Koenigsegg Agera One:1 are the only ones in existence right now. They will make more, but not more than six units. That makes it rather special. Official performance figures are yet to be confirmed for the production version, but the power output suggested for the One:1’s engine ranges between 1,340 to 1,360 horsepower.
