Rumors about a possible Koenigsegg One:1 special edition started to surface on the Internet a long while back. Initially, the odd usage of the number one in its name was because it will be a one-off model, but as more details came out we found that this is actually because the car has one horsepower per kg — an almost unobtainable feat.

Review 2015 Koenigsegg One:1

Unfortunately, the One:1 is not only fast, but it is also super-rare, as only six units will be released. On top of that, all six units have been sold for a handsome sum of about $2.4 million, with the majority of them heading to the Chinese market. With its limited numbers and huge power output, the Koenigsegg One:1 will become an almost immediate legend in the supercar world.

Review 2015 Koenigsegg One:1 Exterior

The designers at Koenigsegg left no stone unturned to make the One:1 as aerodynamically efficient as possible. The result is a hypercar that looks more like a track-only rig than a road-legal car.
To optimize cooling, the car features two large intercooler intakes on the sides along with numerous gills and radiators. Also present is a huge

Review 2015 Koenigsegg One:1 Interior

Compared to the exterior, the interior is less extreme. Extensive use of weight-saving material along with removal of unnecessary luxuries have contributed to a lower curb weight.

Bathed in carbon fiber and dark Alcantara highlighted with orange accents, the interior of the One:1 has a purpose-built appearance.

Drivetrain, Brakes And Handling

This is where the One:1 really shines. Powered by Koenigsegg’s 5.0-liter, twin-turbocharged V-8 engine that can burn biofuel, race fuel or standard gasoline for flexibility.
Koenigsegg hasn’t announced the 0-to-60 time for the One:1 and for a car this fast it would be pointless. Instead, it let us know that this hypercar can rocket to 400 km/h (248 mph) in about 20 seconds. My best estimate on a 0-to-60 time of this beast would be the 2.5-second range — maybe even quicker.

Power is rated at 1 MW (1,341 horsepower) — things are ridiculous when you’re measuring a car’s output in megawatts — with a peak torque of 1,371 Nm (1011 pound-feet) available at 6000 rpm.

Add to the outrageous power output the use of advanced M55J high modulus fibers to decrease the weight of the chassis by 20 percent compared to the standard Agera chassis, and the result is a car with a dry weight of just 2,954 pounds. To put that in perspective the Bugatti Veyron Super Sport has a weight of 4,052 pounds and 1,200 horses propelling it.

Top speed for the car has not yet been officially announced by Koenigsegg, as it said “Top speed has not been a priority.” They aren’t fooling anyone, considering the fact that the car comes fitted with custom Michelin Cup Tires with a speed rating of 440 km/h (273 mph).

For a car this exotic and rare, price shouldn’t really be a concern. But if you are still curious, it’s rumored to be in excess of $2.4 million and all six units have been spoken for.
