Koenigsegg details outrageous new Gemera specs with Dark Matter e-motor

Koenigsegg recently held an event to celebrate an expansion of its campus headquarters in Angelholm, Sweden. We got some initial bits out of it from Koenigsegg Registry, focusing on changes to the production-spec Gemera such as the option to swap the turbocharged 2.0-liter three-cylinder engine for the 5.0 TTV8 from the Jesko. It looks like the Swedes saved the juiciest details for now. Coming straight from founder and boss Christian von Koenigsegg, the Gemera hasn't only been improved by a lot, it's got some outstanding new tech that started with the question of an engine and transmission swap. Engineers had developed a nine-speed gearbox called the Light Speed Transmission (LST) for the Jesko's TTV8. The LST dispenses with a flywheel and clutch or hydraulic coupling, making the TTV8 engine's output shaft the LST's input shaft. At some point during Gemera development, someone wondered if the Gemera could fit the TTV8 and LST instead of the planned Direct Drive transmission from the Koenigsegg Regera. The short story is the engineers answered that question in the affirmative with what's now called the LSTT, the Light Speed Tourbillon Transmission. In the lingo of jewel-like Swiss watch internals, a "tourbillon" is a mechanical feature that makes a watch more accurate. Reworking the LST for its new employment made it smaller, lighter, and better. Alongside that, engineers created a new six-phase e-motor to replace the three, three-phase Quark e-motors that had been paired with the 2.0-liter Tiny Friendly Giant (TFG) engine. The one motor to rule them all is called Dark Matter, designed as a blend of radial flux and axial flux topologies called "raxial." In the original powertrain, two of the Quark motors on the rear axle could each make a maximum 500 horsepower and 738 pound-feet of torque, the third Quark on the crankshaft made 400 hp and 369 lb-ft. transmission. Their combined output in operation came to 1,100 hp.  The Dark Matter makes 800 hp and 922 lb-ft. Pairing a single Dark Matter with the LSTT makes the TFG powertrain lighter and smaller, improving acceleration and performance. New control logic means the Dark Matter can drive the Gemera on its own, the TFG can power the car, or both can be called to action. When operating together, max output comes to 1,400 horsepower and 1,365 pound-feet of torque. The Gemera retains its all-wheel drive, four-wheel steering, and torque vectoring.

Koenigsegg Quark e-motor puts maxi power in a mini package

It seems that what Koenigsegg enjoys just as much as making internal-combustion-powered teleportation devices shaped like cars is creating neat new tech to go in those cars. The new hotness from the minds in Angelholm, Sweden is the Quark electric motor, David silicon carbide inverter, and Terrier EV drive unit. Engineering teams have developed the Quark e-motor for the Gemera sedan, the four-door hypercar, fitting three of them to supplement the three-cylinder, 600-horsepower internal combustion engine. The two major topologies, or designs, for electric motors are axial flux, which emphasizes power density, and radial flux, which emphasizes torque density. The Quark combines both topologies into a form Koenigsegg calls "Raxial flux," fashioned with cost-no-object materials like aerospace-grade steel and a carbon fiber rotor. The result is a 63-pound e-motor about the height of two energy drink cans that produces a steady 134 horsepower and 184 pound-feet of torque. When prodded, maximum output leaps to 335 hp and 441 lb-ft for 20 seconds. The engineering lead said the three e-motors in the Gemera are "to bolster the low-speed" performance "where you need it, for brutal acceleration," after which the ICE will take charge for the run to 400 kilometers per hour (248 mph).  We will undoubtedly be seeing more of this kind of innovation, and in fact, we've already seen it. Two years ago, we interviewed the principals at the Texas-based company Linear Labs, who had created the Hunstable Electric Turbine. The HET is an e-motor that sandwiches a radial e-motor design between two axial e-motor ends. Creators Fred and Brad Hunstable had said that "[for] the same size, same weight, same volume, and the same amount of input energy into the [HET], we will always produce – at a minimum, sometimes more, but at a minimum – two to three times the torque output of any electric motor in the world, and it does this at high efficiency throughout the torque and speed range." Even better, for EV applications, the Hunstables said their motor could operate as a direct-drive unit, eliminating the need for a gearbox. Koenigsegg hasn't gone that far, yet. Before the Quark, the Swedes developed a six-phase silicon-carbide inverter they call David. When two Quarks meet one David and a planetary gearset, they add up to one Terrier, an EV drive unit with all the torque vectoring every electrified hypercar needs.

Performance doesn't matter anymore, it's all about the feel

We've just had a week of supercars and high-end EVs revealed. Many of them boast outrageous performance specs. There were multiple vehicles with horsepower in the four-figure range, and not just sports cars, but SUVs with 0-60 mph times under 3.5 seconds. And it's not just a rarified set of supercar builders, comparatively small tuners are also building this stuff. Going fast is easy nowadays and getting easier. So what will distinguish the greats from the wannabes? It's all about how a car feels. This may seem obvious. "Of course it matters that a car should have good steering feel and a playful chassis!" you say. "Why are you being paid for this stuff?" But a lot of automakers have missed the memo. This past week I spent some time in a BMW M4 Competition convertible, and it's a perfect example of prioritizing performance over experience. It boggles my mind how a company can create such dead and disconnected steering; the weight never changes, there's no feel whatsoever. The chassis is inflappable, but to a fault, because it doesn't feel like anything you're doing is difficult or exciting. The car is astoundingly fast and capable, but it feels less like driving a car and more like tapping in a heading on the Enterprise-D. I also happened to drive something of comparable performance that was much more enjoyable: a Mercedes-AMG GT. It was a basic model with the Stealth Edition blackout package, and even though it had a twin-turbo V8 instead of a six-cylinder, it only made 20 more horsepower. The power wasn't the big differentiator, it was (say it with me) the feel. While not the best example, the steering builds resistance as you dial in lock, giving you a better idea of what's happening up front. Pulses and vibrations come back to you as you move over bumpy pavement in corners. The chassis isn't quite as buttoned down, either, providing a little bit of body roll that tells you you're pushing it. It's also easier to feel when the car is wanting to understeer or oversteer, and how your throttle and steering inputs are affecting it. The whole thing is much more involving, exciting and fun. 2021 Mercedes-AMG GT Stealth Edition View 8 Photos That's also to say nothing of the Merc's sounds. That V8 is maybe not the best sounding engine, but its urgent churn through the opened-up exhaust gets your heart racing. It also seems like it's vibrating the whole cabin, so you feel it as much as you hear it.
