The Koenigsegg One:1 is a track-focused version of the Koenigsegg Agera hypercar. It is named for its equal ratio of power to weight.
Presented at the March 2014 Geneva Motor Show, the Koenigsegg One:1 is the top-of-the-line variant of the Koenigsegg Agera hypercar. Koenigsegg built only six One:1s apart from the car presented at the Geneva Motor Show, all of which have been already sold.
The One:1's name comes from the equal power-to-weight ratio of 1,360 PS to 1,360 kg. 1341 hp (1000 kW) is equal to 1 megawatt (MW), which Koenigsegg claims makes the One:1 the "world's first megacar". Unlike lesser models, the One:1 is more track-focused. Changes include an airscoop on the removable roof, a differently-modeled front end that generates more downforce and reduces boot capacity by 40%.
The One:1's engine is a up-tuned variant of the Koenigsegg 5.0L (5,032 cc) twin-turbo V8 engine found in Koenigsegg's current models, with a power output of 1341 hp (1000 kW) at 7,500 rpm and torque output of 1010 ft·lb (1369 N·m) at 6,000 rpm. Power is delivered to the rear wheels via a seven-speed dual-clutch automatic transmission with paddle shifters.
The One:1 is capable of 0-60 mph (0-97 km/h) in 2.7 seconds, 0-124 mph (0-200 km/h) in 6.6 seconds, 0-186 mph (0-300 km/h) in 11.92 seconds, and 0-200 mph (0-322 km/h) in 14.3 seconds. The One:1 is also capable of a top speed of 273 mph (440 km/h), which would make the One:1 the fastest limited production car in the world.
The Koenigsegg One:1, as it currently stands, is a mid-high end Class S car. It starts with 1562 rank points, gains 124 rank points when maxed out to have 1686 rank points, and gains an additional 82 rank points with Pro Kits to have 1768 rank points. The Tuning Kit is worth +29 for this car. Its main rivals are the Bentley EXP10 Speed 6 and Lamborghini Egoista.
Being an excellent all-rounder and an improved version of the Koenigsegg Agera R, the Koenigsegg One:1 is capable of a great launch and acceleration, accelerating similarly to or better than the Hennessey Venom GT. Handling and drifting have also been improved over the Agera R, and noticeably, the One:1 doesn't skid and/or randomly wreck as often as its lesser counterpart. With a real starting nitro stat of 16.9 mph (27.2 km/h), the car achieves great nitro efficiency rated at 6/11/16, the only Class S car with such ratings. Overall, the One:1 is a car intended for use on virtually all tracks.
However, the Koenigsegg One:1 strangely has a lower real top speed than the Koenigsegg Agera R and Holden Coupe 60. Despite this, it can still outperform these two cars. Ultimately, the One:1's biggest and probably only real downfall is its large display speed multiplier of 85.74%, the worst in the game, along with the SSC Tuatara, SSC Ultimate Aero XT, Hennessey Venom GT, and Devel Sixteen Prototype.
All in all, the Koenigsegg One:1 was and still is a great Class S car to buy and use, although it has virtually no use in current Time-Limited Events anymore due to the emergence of better and faster cars like the McLaren 675LT, McLaren F1 XP-5, Chevrolet 2016 Camaro SS, TRION NEMESIS, and Devel Sixteen Prototype. Due to the peak in overall performance of current top-end cars in Class A and Class S, the One:1 was superseded by the 675LT as the best budget Credits-only car that can perform really well on a single tank. In the case of Class S-only events, the One:1 is still a great bargain if the player can't get the TRION NEMESIS or Devel Sixteen Prototype, as well as later cars like the Aston Martin Vulcan. Its Season 9 race remains one of the best non-Car Mastery opportunities for farming Credits.
The Koenigsegg One:1 costs 2,850,000 to purchase ( 3,000,000 prior to the Multiplayer League Update) and 2,693,450 to max out. Pro Kits 1,681,521, require 20 of each Class S Parts card, 44 Forced-Induction V8 cards, 24 Mid-Tech cards, and 36 Advanced Tech cards.
The Koenigsegg One:1 was added to Asphalt Nitro in the second update and officially made playable since the third update.
The Koenigsegg One:1, again a Class S car, still has identical performance to its Asphalt 8: Airborne rendition. Its main rival is the Lamborghini Aventador LP 700-4. This time, though, the One:1 is now the fastest Credits-purchasable car in the game, unlike in Asphalt 8: Airborne, where later cars made it obsolete.
