Watch Koenigsegg One:1 active aero in action

Christian Von Koenigsegg and Drive are back with another installment of “Inside Koenigsegg.” Episode 3 focuses on the One:1's active rear wing. The naked carbon-fiber wing on the 1,360-hp Koenigsegg One:1 gets a front-top mounting, which reportedly causes less turbulence than a rear-mounted wing. The total weight is about 20 pounds, which von Koenigsegg claims is about 1/3 of what most active wing systems weigh.

But those plans may go a bit awry if a report from Auto Bild is accurate, as Dacia appear to be preparing to take the current Twingo and turn it in to a budget offering for the Dacia range.
