"Koenigsegg has built just over 100 cars since it began production out of a converted fighter jet hangar in 2003. Each car is hand-built to exacting specifications and excruciating detail at Koenigsegg’s factory in Ängelholm, Sweden. The One:1, pronounced as a ratio (“one-to-one”), is the company’s most radical accomplishment thus far. The strange name is representative of the nearly inconceivable 1:1 power to weight ratio. That’s 1341 hp (when running on E85) in a vehicle that weighs just 1360 kg with all fluids and a half tank of fuel. The One:1 will see its driver from 0 to 250 mph in just 20 seconds and can theoretically reach a 273 mph top speed – take it for a spin and try hitting that mark yourself. This rocket ship with wheels intends to set a new lap record at the Nürburgring once management at the famous racing venue allows lap records to be set again. With each of the six $2.4 million hypercars already sold, getting a hand on the wheel of this ultra-exotic in Forza Motorsport 6 is the closest the rest of us may ever get."—forzamotorsport.net
The 2015 Koenigsegg One:1 - abbreviated as Koenigsegg One - is a RWD hypercar by Koenigsegg featured in Forza Motorsport 6 as part of the Mobil 1 Car Pack and as standard in all subsequent main series titles. It also appears in Forza Motorsport 6: Apex as part of the Hyper Endurance Car Pack.
The One:1 was Koenigsegg's top-range model in the Agera model line, with the clear goal of being the fastest car around the track and in speed, with a top speed of 273 mph (440 km/h) even while having among the sharpest cornering forces of any road car. The One:1's name is derived from its equal ratio of metric horsepower (PS) to kilogram weight (kg), leading it to become known as the first "megacar".
It is also one of the most exclusive hypercars ever made, with only seven units made, including a prototype, each priced at over US$2.4 million.
Engine and drivetrain
The Koenigsegg One:1 is powered by a 5.0 L (5,032 cc) twin-turbocharged V8 engine with 1341 hp (1000 kW) at 7,500 rpm and 1311 ft·lb (1777 N·m) at 6,000 rpm, with a redline set to 8,250 rpm and a fuel cutoff point of 8,500 rpm, although the Forza renditions of the car have an incorrect displacement of 5.1 L (5,065 cc). It has a compression ratio of 9.0:1 has a bore and stroke of 92×95.25 mm. The engine produces 26.1 psi (1.8 bar) of boost and weighs only 434 lb (197 kg).
The transmission used is a rear-driving, specially developed seven-speed dual-clutch, single input shaft automatic transmission with paddle shifters located behind the steering wheel. An electronic differential is also used.
To support the 1 megawatt (MW) of power, the One:1 features large air vents for improved cooling and a roof air scoop that sits on the removable roof, making it impossible to stow the roof into the boot unlike previous models. Koenigsegg took advantage of this to model the front to create more downforce, reducing boot capacity by 40%. 1345 lb (610 kg) of downforce is generated at 162 mph (260 km/h) and 1830 lb (830 kg) at 273 mph (440 km/h).
It is built on an advanced carbon fiber chassis with Formula One-stle honeycomb core and integrated fuel tanks for optimal weight distribution and safety, resulting with 44% front weight distribution. Double wishbone suspensions, active ride height control, and rear triplex dampers are used. The car weighs 2998 lb (1360 kg), resulting in a power-to-weight ratio of 986 hp (735 kW) per tonne or 1 metric horsepower (PS) per kilogram (kg).
The Koenigsegg One:1 stands out with extreme acceleration times including 0 to 60 mph (97 km/h) in 2.7 seconds and 0 to 100 mph (161 km/h) in 4.5 seconds. Its equally impressive top speed is 266 mph (428 km/h) in the Motorsport series and 268 mph (431 km/h) in the Horizon series, making it one of the fastest cars in both series.
To complement its very quick acceleration and extreme top speed, the One:1 delivers tons of downforce for handling corners and comes with highly responsive braking, although it also suffers from moderate to strong wheelspin up to fourth gear with traction control disabled.
Due to a tremendous straight-line performance and outstanding handling, the One:1 is one of the best cars in the series for high-speed races, although its tendency to wheelspins makes it more suitable for experienced drivers with decent throttle management skills.

- Even though the One:1 in real life is a targa top roadster like with Koenigsegg's models, in-game, the roof cannot be removed.
- The Koenigsegg One:1 appears in the start of Forza Horizon 3 as one of the racers heading for the Byron Bay Festival, alongside the 2017 Ford GT, Ferrari FXX K, and Audi R8 V10 plus.
- The One:1's in-game torque output appears as 1010 ft·lb (1371 N·m).
- The One:1's interior shows a discrepancy on the steering wheel: the button icons from the Agera and the One:1 appear on top of each other.
- In addition, the orange stripe used in the manufacturer colors for the car ends in the wrong place.
