The company was founded in 1994 in Sweden by Christian von Koenigsegg, with the intention of producing a "world-class" sports car.

The goal was to develop a car homologated for use worldwide, particularly the United States whose strict regulations did not allow the import of earlier Koenigsegg models.

Koenigsegg is also active in development programs of plug-in electric cars' systems and next-generation reciprocating engine technologies.

[7] Koenigsegg develops and produces most of the main systems, subsystems and components needed for its cars in-house instead of relying on subcontractors.

[11][12] Christian von Koenigsegg got the idea to build his own car after watching the Norwegian stop-motion animated movie The Pinchcliffe Grand Prix in his youth.

These Subaru 1235 engines were purchased and modified for use in the CC; this deal failed when the founder of Motori Moderni died, sending the company into bankruptcy.

It later developed its own engines from scratch, including control systems and transmissions, which is very unusual for a small size sports car producer.

[23] The deal, set to close 30 September 2009, included US$600 million in financing from the European Investment Bank, guaranteed by the Swedish government.

[28] In 2006, Koenigsegg introduced the CCX, a new model, that was developed in order to meet worldwide regulations for road use.

[31] In 2009, Koenigsegg released information about a special edition car called the Trevita, of which three were planned to be made but only two were finished due to technical problems.

The Trevita, which translates into English as "three whites", has a body made entirely of Koenigsegg's proprietary material consisting of diamond-coated carbon fibre.

[32] In 2010 Koenigsegg released information at the 2010 Geneva Motor Show about a new model called the Agera, which translates into English as "take action/act".

At the 2015 Geneva Motor Show, Koenigsegg presented a new model named the Regera, which translates into English as to "reign" or "rule".

Below 48 km/h (30 mph), motive power is by two electric motors on the rear wheels and the internal combustion engine (ICE) is disconnected.

The vehicle is powered by a small engine called the Koenigsegg TFG (Tiny Friendly Giant).

The car also features full-length Koenigsegg Automated Twisted Synchrohelix Actuation Doors (KATSAD).

[39] [41] [52] [53] On 28 February 2005, at 12:08 pm local time, in Nardò, Italy, the CCR broke the Guinness World Record for the fastest production car in the world, having attained 387.866 km/h (241.009 mph) on the Nardò Ring (a circular track of 7.8 mi (12.6 km) circumference), breaking the record previously held by the McLaren F1.

[73] In 2008 the German magazine sport auto conducted a 0–300–0 km/h (0–186–0 mph) test for production cars, with the CCX winning the event in a total time of 29.2 seconds.

[78] On 4 November 2017, an Agera RS set a new record for the world's fastest production car with an average speed of 447.19 km/h (277.87 mph) with Koenigsegg test driver Niklas Lilja behind the wheel.

[81] The record was set at Örebro Airport by Koenigsegg development driver Markus Lundh, who cited improvements in the track surface and the new Michelin Cup 2 R tyres as reasons for the faster run.
