Not one to let the inadequacies of existing technology stand in its way, Koenigsegg has been an innovating pioneer in modern powertrain technology, rethinking fundamentals with solutions like gearbox-free direct-drive hybrids and camshaft-free engines. Its latest breakthrough has come in the form of a compact electric motor that squeezes together the torque-heavy benefits of axial flux topology with the power-dense boost of a radial flux layout. The all-new Quark motor will help the boundary-smashing Gemera four-seat GT achieve sprint times formerly reserved for the world's quickest electric coupes while supporting a wide range of applications from aerospace to marine.

Developing the world's first "mega-GT," a four-seat grand tourer with power and performance figures to rival the world's most expensive, overpowered hyper-coupes, is no easy task. Koenigsegg continues to approach it by shrinking down its powertrain, work that started with shoehorning 590 hp into a 2.0-liter three-cylinder fossil free-fuel engine it calls the "Tiny Friendly Giant." It's always planned to configure that engine within a gearbox-free Koenigsegg Direct Drive (KDD) layout, using three complementary electric motors. This week, it's provided a closer look at what the small, potent e-machines will look like.

Koenigsegg applied principles from existing radial flux and axial flux motors to develop what it calls Raxial Flux topology. It doesn't explain what exactly that combination looks like in practice, but it does promise the best torque-to-power-to-weight ratio in the industry. The Quark motor's 8.5 kW/kg power-weight ratio doesn't exceed previously set benchmarks, but the 66-lb (30-kg) motor really shines in its 443 lb-ft (600 Nm) of peak torque.

Pingy!............

590 hp into a 2.0-liter three-cylinder fossil free-fuel engine

I am sorry, but I do not believe that a 120 cubic inches at 590 hp will endure long if it is pushed touse those 590 horses on a regular basis. No replacement for displacement.

An improvement on the flux capacitor?

I dont think so.

[Red Badger]

This is just the beginning.

We are at the ‘Model T’ era of true electric vehicles..............

“...the torque-heavy benefits of axial flux topology with the power-dense boost of a radial flux layout”
I love it when they talk dirty.

[Demiurge2]

Agreed, but not quite yet. We’re still waiting for the Model T of electric cars. The current contenders are more like pricy, gimmicky toys.

[Deaf Smith]

Is Nm no longer nanometers?

[Dr. Sivana]

We are at the ‘Model T’ era of true electric vehicles...

The motors aren't really an issue. On board energy storage or generation is the limiting factor right now.

[Lurker]

Newton/meters I’d guess.

“.the torque-heavy benefits of axial flux topology with the power-dense boost of a radial flux layout””

Well and good but the masses, me included, won’t buy an electric because of its acceleration.

[Yo-Yo]

YASA is already making YASA 750R motors are connected together like a three-rotor rotary engine to power the Rolls Royce ACCEL electric speed record setting airplane.

Nm is Newton metre, a unit of torque. The symbol for nanometre is nm. Note the difference in case.

[reg45]

See post #15. Newton/meter is not correct. Newton is kilogram_metre/sec^2 so Newton/metre would be kilogram/sec^2 a nonsense unit.

[Deaf Smith]

Okay, I did find 1 Newtonmeter = 0.7376 ft/lb.

I've had SAE torque wrenches, one metric kg and one small Nm wrench that got lost and went to seat-snug.

Just have never seen one for Newtonmeters.

[Deaf Smith]

Okay, must have been nm in the shop manuals.

[Red Badger]

Little ‘n’ is nanometers, CAPITAL ‘N’ is NEWTON-Meters....................

[reg45]

I run into that all the time. The worst one is Kg which means Kelvin.gram a nonsense unit, instead of kg, kilogram a unit of mass.
