There's a new challenger to the throne of fastest production car in the world — and while its Swedish origins might inspire some doubt, just seeing the Koenigsegg One:1 is enough to eliminate your incredulity. Its limited run of just half a dozen cars (each already sold) may draw into question its status as a production car, but one thing that's beyond question is its ability to produce some serious power. With a state-of-the-art turbocharged V8 engine, it's capable of producing 1,360 horsepower and 737 pound-feet of torque across an incredibly flat curve. Built as a race car that can be comfortably driven on the street, it has a wealth of tech taken straight from the track world: like an almost completely carbon fiber construction, adaptive aerodynamics, and a top-mounted wing. And since it claims to be able to reach 280 miles-per-hour, the Germans and Italians may be looking north for inspiration on their next run of so-called super cars.
