Koenigsegg Quark electric motor torque curve

The Quark electric motor weighs 63 pounds and develops up to 335 hp and 486 lb-ft of torque. Aerospace-spec steel and direct cooling helps to keep the size small, while carbon-fiber parts, made using the same processes that Koenigsegg uses for its carbon wheels, help to keep the weight down.

Koenigsegg also describes the motor as featuring a balance between radial (good for power density) and axial (good for torque density) flux designs, something the company has dubbed Raxial Flux. The result is that it doesn’t need a step-down transmission like many rival small, high-revving motors, or at most only a small transmission, helping to improve efficiency while also saving weight and complexity.

Among the first applications for the Quark is Koenigsegg’s Gemera hypercar, which will feature three of the motors in combination with a downsized internal-combustion engine for a total 1,700 hp. According to the motor’s lead designer, Dragos-Mihai Postariu, the motors will help the Gemera deliver “brutal” acceleration at low speeds, and will then work with the internal-combustion engine to help deliver a continuous record-speed push to 400 kph [248 mph] without any torque or power losses.”

Koenigsegg also imagines the components being applicable in the marine and aviation industries.
