The Koenigsegg Regera is a limited production, plug-in hybrid sports car manufactured by Swedish manufacturer of high-performance sports cars Koenigsegg. It was unveiled at the 2015 Geneva Motor Show. The name Regera is a Swedish verb, meaning "to reign." Only 80 units will be built, each costing approximately USD 1.9 million. The Regera was created and designed to be a more “practical”, “luxury”, hypercar alternative to the rest of Koenigsegg’s lightweight hypercar lineup, including the Agera RS and the One:1. Koenigsegg states that the Regera will be the most powerful and fastest accelerating production car ever. The production of the Regera will result in Koenigsegg, for the first time ever, simultaneously having two models in production.

Specifications
The Regera produces a reported total of 1,822 metric horsepower through a hybrid powertrain, but the power peaks of the electric motors and the internal combustion engine(ICE) are spread out, or not simultaneous, leaving a maximum combined mechanical output of 1,500 metric horsepower and 1,475 pound-feet of torque. The ICE is a mid-rear mounted, in-house developed, twin-turbocharged V8 engine with a 5.0-litre capacity. It produces 820 kW (1,100 bhp; 1,115 PS) at 7,800 RPM and 1,280 Nm (944.1 ft-lb) at 4,100 RPM. It works in conjunction with three YASA electric motors with a total capacity of 520 kW (697 bhp) and 900 Nm (663.8 ft-lb) of electric torque. One 215 bhp (160 kW) electric motor on the crankshaft supplies torque fill while acting as both a generator and a starter motor and two 241 bhp (180 kW) wheel shaft mounted electric motors drive the rear wheels and provide torque vectoring. At speeds below 30 mph and in reverse, only the wheel shaft electric motors propel the car through the use of a hydraulic coupling that disconnects the ICE and the crankshaft mounted electric motor. The electric motors are powered by a 9.27 kWh, 620-volt, liquid cooled battery pack developed by Rimac, providing up to 22 miles (35 km) of pure electric mode in city driving. Koenigsegg claims that the battery pack is the most power-dense battery pack every created for a production car.

Transmission
Christian von Koenigsegg invented the Koenigsegg Direct Drive System (KDD) and it was developed for the Regera by the Koenigsegg Advanced Engineering Team. The KDD system effectively eliminates the need for a transmission and allows for pure EV (electric vehicle) mode. The Regera doesn't have a traditional multi-gear transmission but instead features a single-speed fixed gear transmission, often called a direct drive, with a 2.85:1 reduction ratio, meaning the crankshaft mounted on the ICE will rotate 2.85 times for every 1 time that the output shaft of the direct drive mechanism will rotate. The RPM of the crankshaft mounted electric motor and internal combustion engine are proportional to wheel speed above 30 mph. Koenigsegg reported that the omission of a gearbox and addition of electric motors and battery only added 88 kg (194 lb) compared to what the Regera would have weighed with the same combustion engine but a 7-speed DCT (dual-clutch) transmission and no electric motors or batteries.

Interior Features
The Regera will include added insulation to help add to the “luxury” by reducing cabin noise caused by wind and ‘powertrain’ noises. Also included as an added “luxury” item over previous models will be 8 way electrically adjustable memory foam seats. The Regera will also include many new tech features such as a Koenigsegg 9-inch ‘infotainment’ system, a complete camera system with recording capabilities (front, inner, and rear), Apple ‘CarPlay’, a new sound system, ambient lighting, and 3G and Wi-fi connectivity. It will also feature front and rear parking sensors to help “make parking easier”.

The Regera will feature active engine mounts for the ICE and transmission to rest on. The engine mounts are designed to stay soft at lower speeds, significantly reducing vibrations and engine noise, adding to the "luxury" effect of the vehicle. While driving more aggressively or at higher speeds, the engine mounts will firm up, giving greater lateral response to the vehicle.

Exterior Features
Christian von Koenigsegg believes that a good design of the day-time running (DRL) lights on a vehicle gives it "character," and developed a DRL system that is supposed to resemble a constellation with the carbon fiber background resembling the night sky.

Koenigsegg claims that the Regera is the first "fully-robotized" car. The vehicle features hydraulic pumps and accumulators to control the active front and rear wings, as well as active chassis control and lifting. Hydraulic lifters were added to the already existing pumps and accumulators to allow for all body panels on the vehicle to be remotely operated.

Performance
Koenigsegg states that the car has a top speed of 410 km/h (255 mph), is capable of reaching 100 km/h (62 mph) in 2.8 seconds, 300 km/h (190 mph) in 12.3 seconds, and a speed of 400 km/h (250 mph) in less than 20 seconds. Koenigsegg also claim that the acceleration from 150 to 250 km/h (from 93 to 155 mph) requires 3.2 seconds.
