The Koenigsegg Agera is a mid-engined sports car made by Swedish car manufacturer Koenigsegg as of 2011. It is a successor to the Koenigsegg CCX/CCXR. The name Agera comes from the Swedish verb 'agera' which means "to act” or "to take action".
The Agera is powered by an in-house developed 5.0-litre twin-turbocharged V8 engine which produces 940 hp (701 kW) at 6900 rpm and 1,100 N·m (810 lb·ft) of torque at 4000 rpm. Total weight of the engine is only 197 kg (434 lb) thanks to a carbon fiber intake manifold and the aluminum construction.The transmission is a 7-speed dual clutch with paddle shifters. It is the first dual clutch transmission to feature only one input shaft. The second clutch slows down the input shaft during up shifts in order to reduce the time it takes to synchronize the next gear, resulting in faster shift times. Most notably, the transmission weighs only 81 kg (179 lb).
0–100 km/h (0–62 mph) in 3.1 sec
0–200 km/h (0–124 mph) in 8.9 sec[6]
Maximum speed for the production model is unknown, but is believed to be above 410 km/h.

The Agera has a body made from pre-impregnated carbon fiber/kevlar with lightweight reinforcements. The car's hardtop roof is stowable under the front hood lid. The chassis is also made out of carbon fiber with an aluminum honeycomb that comes with integrated fuel tanks for optimal weight distribution and safety. The rear wing is electronically adjustable with auto setting or manual control in order to have as little compromise as possible between low drag and down force, depending on situation and mood.[7] The Agera comes with forged aluminum wheels with center locking, measuring 19" on the front and 20" on the back and wrapped in a set of Michelin Super Sport tires that can be used with speeds of up to 260 mph (420 km/h). Other highlights include the trademark Koenigsegg doors, a new traction control system, LED lighting, blue hood stripes that continue on through the cockpit of the car and a custom interior with a new “Ghost light” lighting system, which uses carbon nanotubes in a unique configuration to shine through the car's aluminum buttons.

The Agera R made its debut at the March 2011 Geneva Motor Show—with a Speed Racer livery theme, special Michelin tires and a Thule Rt. It can accelerate from 0–100 km/h (62 mph) in 2.9 seconds and reach a theoretical top speed of 440 km/h. The Agera R has a drag coefficient (Cd) of 0.37, or 0.33 at high speed due to its adaptive rear wing, while producing 300 kg of downforce at 250 km/h. 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, an excellent example Koenigsegg's uncompromising and efficient designing philosophy [6]

On 2 September, during test sessions in Ängelholm, the Agera R broke six world land speed records for a production car, including 0–300 km/h in 14.53 seconds, and an astonishing 0-300-0 km/h in only 21.19 seconds,[9] a record yet to be broken. The outstanding braking performance required to maintain this record is enabled in part by the Agera's incredible stability, demonstrated by Koenigsegg's test driver and drivetrain technician Robert Serwanski, who was recorded by passenger Rob Ferretti (founder of the group "Super Speeders") braking from 186 mph to 0 without holding the steering wheel.
