It seems what Koenigsegg Just as exciting as building internal combustion engine-powered teleporters in the shape of cars is creating neat new technology for riding in those cars. New highlights from mind in Angelholm, Sweden are the Quark electric motor, David silicon carbide inverter and the Terrier EV actuator. Engineering teams have developed the Quark electronic engine for the Gemera sedan, four-door hypercar, fitted three of them to complement the three-cylinder, 600-horsepower internal combustion engine. The two main topologies or designs for electric motors are the axial flux, which emphasizes power density, and the radial flux, which emphasizes torque density. Quark combines both topologies into a form that Koenigsegg calls “Raxial flux”, made from inexpensive materials like aviation-grade steel and carbon fiber rotor.
The result is an e-motor that weighs 63 pounds the height of two energy drinks, producing a steady 134 horsepower and 184 pound-feet of torque. When activated, maximum power spikes to 335 hp and 441 lb-ft in 20 seconds. The engineering team lead says the three e-motors in the Gemera are “to enhance” performance “low speed” where you need it, for strong acceleration”, after which ICE will take charge of the running range up to 400 kilometers per hour (248 mph).
We will no doubt see more of this type of innovation and, in fact, we have already seen it. Two years ago, we interviewed principals at Linear Labs Company is based in Texas, who created the Hunstable Electric Turbine. The HET is an e-motor that clamps a radial e-motor design between two axial e-motor heads. Creators Fred and Brad Huntstable said that “[for] same size, same weight, same mass and same amount of energy input [HET]we will always produce – at a minimum, sometimes more, but a minimum – two to three times the torque output of any electric motor in the world, and it does this with great efficiency. High performance throughout the torque and speed range. “Even better For EV applications, Hunstables says their engine can act as a direct-drive unit, eliminating the need for a gearbox.
Koenigsegg hasn’t come that far yet. Before Quark, the Swedes developed a six-phase silicon-carbide inverter they called David. When the two Quarks meet a David and a planetary gearset, they add in a Terrier, an EV drivetrain with all the torque vectoring for all the needs of an electrified hypercar. For 268 hp and 368 lb-ft continuous blasts and instantaneous 770 hp and 882 lb-ft bursts, the Terrier weighs in at just 187 pounds, the unit’s weight being reduced in part by requiring only one inverter. six phases for its two Quarks. need two of the more traditional three-phase inverters. The automaker says the part can be “elastically bolted” to a carbon fiber monocoque, which saves more weight on the chassis than using mounting hardware or a subframe.
Koenigsegg plans to offer the Quark for applications beyond EVs, including aerospace and marine uses, and perhaps a VTOL like the air taxi we’ve been waiting for since. The Jetsons.
