Koenigsegg's New EV Power Pack: 670 HP, Less Than 200 Pounds

We already know "David," which is what Koneigsegg has named the its in-house EV inverter design featured on the Gemera. "David" can convert up to 750 kW of power from 850 volts of direct current flowing from the batteries into alternating current that can power the car's motors. The news today is that Koenigsegg has a name for the power unit that will feature this inverter, and plans sell its innovative in-house components in a new and incredibly powerful package.

A single Koenigsegg Quark motor produces 250 kW, or 335 hp, and 443 lb-ft of torque at its peak output, and weighs just 63 pounds.

The newly announced "Terrier" power unit features two of these Quark motors packaged around the fancy David inverter. The result is a plug-and-play EV power unit that puts out 670 hp and weighs less than 200 pounds, and also offers cross-axle torque vectoring performance. The output shafts are equipped with planetary gear sets, and the unit can be even mounted directly to a vehicle chassis—no subframe required. Koenigsegg believes there are extensive applications for the compact, high-power unit, including boats and aviation, where it could replace high-revving engines that normally require additional gearing, providing a lighter and less complex solution.

On the hybrid Gemera, which features a battery pack powering three Quark motors linked up with a three-cylinder internal combustion engine, the goal was smooth and seamless acceleration with no power loss. Koenigsegg's name for the optimized power and torque map it has programmed into its Quark motors to achieve this is "Raxial Flux," which sounds fancy and has something to do with how the network of motor components in the motor interact.

Today's electric motors are typically split between two different conceptual designs. Radial flux motors are power dense with a magnetic field radiating perpendicular to the axis of rotation, commonly packaged as a pancake or hub motor. Axial flux motors are currently more common, and barrel-shaped with a magnetic field radiating parallel to the axis of motion. Our E-motors 101 piece goes into more detail on how it works. Koenigsegg's new "Raxial Flux" have seemingly engineered a motor capable of both typical characteristics for optimized motor performance.

While we wait for more details on the layout of the Quark motor, we posit it likely has its permanent magnets arrayed in a manner that can be energized either axially or radially, and that there are electric stator winding phases located both radially and axially, and energized independently under whatever conditions are optimal for each design's power and torque delivery. Essentially, Koenigsegg smashed both layouts together and designed programming to make it work.

What you really need to know is that it means "optimal" power delivery from the motor, and doesn't need a transmission or step gears because "the RPM of the motor is right from the get-go," according to CEO Christian von Koenigsegg.

Peak torque and power from the electric motors is reached 20 seconds into acceleration, and then the motors drop to nominal output. At this point, the 600-hp three-cylinder gas engine carries the car to top speed.
