Koenigsegg Agera R (2011–2014) The Agera R made its debut at the March 2011
Geneva Motor Show with a
Speed Racer livery, and special
Michelin tyres. It can accelerate from in 2.8 seconds and attain a theoretical top speed of . The Agera R has a , or at high speed due to its adaptive rear wing, while producing of downforce at . This adaptive rear wing system is lighter than conventional hydraulic/electrical adaptive systems, and has the unique ability to compensate for head/tailwind due to its spring-loaded design. Furthermore, the pylons holding the wing play not only a role in the Agera R's aerodynamic performance, but also assist in extracting hot air from the engine bay. The braking performance required to maintain this record is enabled in part by the Agera's stability, demonstrated by Koenigsegg test driver and drivetrain technician Robert Serwanski, who was recorded by passenger Rob Ferretti (founder of the group "Super Speeders") braking from 300 km/h to 0 without holding the steering wheel. The Agera R can produce lateral cornering forces of 1.60 G, due to a combination of mechanical balance and high levels of grip from the specially developed Michelin Supersport tyres. The 2013 version of the Agera R premiered at the 2012 Geneva Motor Show. Upgrades included carbon fibre wheels, enhanced aerodynamics, and engine upgrades allowing the Agera R's twin-turbo V8 engine to have a power output of at 7,100 rpm and of torque at 4,100 rpm on E85 biofuel. Koenigsegg's Flex Fuel Sensor technology allows the ECU to respond to varying fuel qualities and alcohol content by reducing power levels as a means of protecting the engine. On standard low-octane fuels, power is reduced to . In 2013, one Agera S was the 100th Koenigsegg ever produced, celebrated by a specially built car with gold leaf inlays named "Hundra" (Swedish for "one hundred").
Koenigsegg One:1 (2014–2015) The Koenigsegg One:1 was presented at the 2014
Geneva Motor Show held in March. Koenigsegg built six cars apart from the car presented at the Geneva Motor Show, all of which were already sold. Koenigsegg took two cars to the 2014
Goodwood Festival of Speed, where they were displayed alongside other sports cars such as the
McLaren P1,
LaFerrari, the
Porsche 918 Spyder and the
Pagani Huayra. The car is fitted with a variant of the same 5.0 L twin-turbocharged V8 engine used in the other Agera variants. It generates a maximum power output of at 7,500 rpm and of torque at 6,000 rpm. The transmission is a 7-speed dual clutch paddle shift as used in other variants of the Agera. The name One:1 comes from the
power-to-weight ratio (1,360 PS to 1360 kg) giving the car 1 PS per 1 kg mass. The 1,360 PS power output is the equivalent of one
megawatt, which Koenigsegg claims make the One:1 the 'world's first megacar'. The car is track-focused as opposed to the previous cars made by Koenigsegg, leading to changes such as limited boot space.

Koenigsegg Agera RS (2015–2018) The Agera RS was unveiled at the
2015 Geneva Motor Show, along with the prototype version of the
Regera. The Agera RS is an advanced version of the Agera R, implementing some of the new technology and features of the One:1 and combining the features of the Agera R and the Agera S. Koenigsegg billed it as "the ultimate track tool" due to its lightweight features and track optimised technologies. The Agera RS produces 450 kg of downforce at 250 km/h. The 5.0-litre V8 engine now has a power output of on regular pump gasoline. The optional 1-megawatt package increases the engine's power to . 27 units of the Agera RS were built. The model was initially going to be limited to 25 units, however two extra cars were built, one being the factory development car and one as a replacement for a customer car damaged while it was being used for shakedown testing (Agera RS Phoenix built after the crash of Agera RS Gryphon). The Agera RS has the following fuel economy: * in the city and on the highway – which averages to . The last Agera RS rolled off the production line on 4 April 2018.
Koenigsegg Agera Final Edition (2016–2018) At the
2016 Geneva Motor Show, a final three-car series of the Agera was announced as a final celebration of the Agera range and as the last models to wear the Agera badge. The cars could be fully customised and combined with the Agera RS chassis with the One:1 engine. The first car to be unveiled was called the 'One of One'. It featured a unique orange paint scheme with bare carbon and blue accents. The exterior of the car was complemented with a large adjustable rear wing similar to the One:1 and triple front canards along with a large front splitter. The other two distinct final edition cars were unveiled online in July 2018 and were called 'Agera FE Thor' and 'Agera FE Väder' respectively. Thor features a custom two-tone black paintwork consisting of crushed diamonds and white accents. The exterior features a large rear wing reminiscent of that found on the Agera XS, and a different set of front canards, along with a large front splitter and a Le Mans-style central fin for improved downforce, setting it apart from the rest of the Agera models. Väder features the same crushed diamond paintwork with a bare carbon fibre centre along with white accents, incorporating the same rear wing as Thor but excludes the central fin. Both cars made their public appearance at the 2018
Goodwood Festival of Speed. ==Special editions==
