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" or "to rule." Only 80 units will be built, of which 40 have already been sold as of March 2016, each costing approximately US$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. As in general, the Regera's internal combustion engine (ICE) produces its greatest power only at high RPMs; however, due to the fixed gear, this corresponds to very high speeds. Power at low speeds is filled in by the electric motors, giving 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 torque. One 215 bhp (160 kW) electric motor-generator on the crankshaft acts as starter and generator and supplies torque fill; and two 241 bhp (180 kW) wheel-shaft mounted electric motors drive the each rear wheel and provide torque vectoring. The electric motors are powered by a 4.5-kWh, 800-volt, 75-kg liquid cooled battery pack developed by Rimac Automobili, making it the first 800-volt production car. Koenigsegg claims that the battery pack is the most power-dense battery pack ever 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 2.73:1 reduction ratio, meaning the crankshaft mounted on the ICE will rotate 2.73 times for every 1 time that the output shaft of the direct drive mechanism will rotate. At speeds below 30 mph, mostly the wheel shaft electric motors propel the car through the use of a hydraulic coupling that lets the ICE and the crankshaft mounted electric motor slip. In reverse, only the wheel shaft electric motors propel the car. Above 30 mph, the RPM of the crankshaft mounted electric motor and internal combustion engine are proportional to wheel speed through locking of the hydraulic coupling. However, in the first driving footage from the Regera through Koenigseggs official Youtube channel, Christian von Koenigsegg described and demonstrated how the Regera features a steering wheel mounted paddle that simulates a traditional downshift by initiating slip of the hydraulic coupling connecting the crankshaft to the output shaft. This results in higher RPM of the ICE and the cranskshaft mounted electric motor and therefore higher power at lower speeds than what would have been possible if the coupling would have been locked at all times. 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 dual-clutch transmission (DCT) 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 technical features such as a Koenigsegg 9-inch information and entertainment 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.
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 10.9 seconds, and a speed of 400 km/h (250 mph) in 20 seconds. Koenigsegg also claims that the acceleration from 150 to 250 km/h (from 93 to 155 mph) requires 3.9 seconds.
