Koenigsegg Dark Matter revealed – 800 PS, 1,250 Nm; The most powerful car electric motor in the world
Koenigsegg revealed about production-spec Gemera includes a lot of big numbers, and the most interesting thing comes from the Dark Matter electric motor used in the “family-focused” four-seater. On its own, the e-motor delivers a staggering 800 PS (789 hp or 588 kW) and 1,250 Nm.
The Swedish automaker says the Dark Matter is the world’s most powerful automotive-grade electric motor with six-phase technology and the world’s first motor for production cars. Most e-motors used in electric vehicles (EVs) today use three-phase (a group of copper coils wound forming an electromagnet in the stator), including quark which Dark Matter replaces in Gemera.
Both Quarks and Dark Matter are considered to be “axial flux” electronic engines, which are a combination of radial and axial structures. A radial flux e-motor has more power but less torque, while an axial-flux e-motor has the opposite: it provides more torque but less power.
In a radial unit, the magnetic flux path (the number of electric or magnetic field lines passing through a surface) is much longer than the axial line because it goes from one rotor pole to the first tooth in the stator, then through the stator to the second tooth until it reaches another rotor pole again.
The axial unit has a direct and shorter flux path, as it passes directly from pole to pole through the air gap (the actual physical gap in an electric motor that separates the moving rotor and the stator core), ensuring that the magnetic field remains strong with a shorter path.
To get the best of both worlds for radial flux units, Koenigsegg simply increased the rotor diameter relative to the majority of the stator and optimized the stator outside diameter to be able to accept this additional flux. Both Quark and Dark Matter look like a single shaft unit and are compact in size, with the former measuring 334 mm wide, 303 mm tall and 112 mm deep.
Dark Matter is slightly larger with a width of 381.5 mm, a height of 383.3 mm and a depth of 135.5 mm. The difference in weight between the two is only 9 kg, where the Quark outperforms the 30 kg in the Gemera show car, while the Dark Matter is 39 kg. This is likely due to the forged carbon fiber case, as suggested by the device’s photos.
Power for Dark Matter is provided by an 850-volt battery located under the front seats with an energy capacity of 14 kWh. The company isn’t disclosing further details at the moment, but the production Gemera could use the same silicon carbide (SiC) six-phase inverter – known as the David – as the Gemera show car launched in 2020.
The Dark Matter e-motor powers all four wheels of the Gemera through the new Light Speed Tourbillion Transmission (LSTT), which is an evolution of the Light Speed Transmission used in the Jesko, providing all-wheel drive and four-wheel torque vectoring. The LSTT multi-clutch also works with automotive TFG and HV8 engines.
