The new era of hybrid hypercars - Koenigsegg Regera

By Ryan

  Usually hybrid cars give us an impression that they are slowly family cars, however, this idea is changing with the arise of more and more hybrid supercars, especially after Koenigsegg announced its latest flagship model: Regera.

  Regera was unveiled at the 2015 Geneva Motor Show. The name Regera is a Swedish verb, meaning "to reign" or "to rule." 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.

  The Regera produces a reported total of 1,822 metric horsepower through a hybrid powertrain. However, because the internal combustion engine (ICE) in the Regera has a fixed gear instead of a gearbox and therefore only delivers peak power at a very high speed while the electrical motors in the Regera deliver their peak power at a lower speed, the power peaks of the ICE and the electrical motors 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 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. The electric motors are powered by a 4.5 kWh, 800-volt, 90 kg liquid cooled battery pack developed by Rimac Automobili, making it the first 800 volt production car, Koenigsegg also claims that the battery pack is the most power-dense battery pack ever created for a production car.

  It has to say that Koenigsegg makes an example for high-performance hypercars in the future, since the growing tensions of energy shortage, car manufactures have to do more research on electric power, and Regera proves that electric power is no inferior than combustion engines.
