Not one to let the inadequacies of current know-how stand in its means, Koenigsegg has been an innovating pioneer in trendy powertrain know-how, rethinking fundamentals with options like gearbox-free direct-drive hybrids and camshaft-free engines. Its newest breakthrough has come within the type of a compact electrical motor that squeezes collectively the torque-heavy advantages of axial flux topology with the power-dense increase of a radial flux format. The all-new Quark motor will assist the boundary-smashing Gemera four-seat GT obtain dash instances previously reserved for the world's quickest electrical coupes whereas supporting a variety of functions from aerospace to marine.
Growing the world's first "mega-GT," a four-seat grand tourer with energy and efficiency figures to rival the world's costliest, overpowered hyper-coupes, is not any simple process. Koenigsegg continues to strategy it by shrinking down its powertrain, work that began with shoehorning 590 hp right into a 2.0-liter three-cylinder fossil free-fuel engine it calls the "Tiny Pleasant Big." It is all the time deliberate to configure that engine inside a gearbox-free Koenigsegg Direct Drive (KDD) format, utilizing three complementary electrical motors. This week, it is offered a more in-depth take a look at what the small, potent e-machines will appear to be.
Koenigsegg utilized ideas from current radial flux and axial flux motors to develop what it calls Raxial Flux topology. It does not clarify what precisely that mixture seems to be like in apply, nevertheless it does promise the most effective torque-to-power-to-weight ratio within the business. The Quark motor's 8.5 kW/kg power-weight ratio does not exceed beforehand set benchmarks, however the 66-lb (30-kg) motor actually shines in its 443 lb-ft (600 Nm) of peak torque.
"The Quark is designed to bolster the low-speed vary of the Gemera, the place you want it, for brutal acceleration," defined Dragos-Mihai Postariu, electrical motor design lead. "The ICE then focuses on the high-speed vary. What this implies by way of efficiency for the Gemera is an enormous energy surge adopted by a steady record-speed push to 400 km/h (249 mph) with none torque or energy losses."
Backside line: The Gemera will launch from 0 to 62 (100 km/h) in 1.9 seconds, as rapidly as nearly any all-electric supercar on Earth, then proceed supernatural ranges of acceleration up by way of 249 mph ... all whereas packing the flexibility to shuttle the entire household (of 4) to the airport.
Contributing to the low weight of the Quark (pictured subsequent to an 11.2-oz/330-ml can of power drink for perspective) just isn't solely its compact 12 x 13 x 4.4-in (303 x 334 x 112-mm) dimension but in addition the no-expense-spared supplies that go into its development. These embody an aerospace-grade 300M metal shaft and a rotor that makes use of the Aircore hole carbon fiber know-how Koenigsegg launched on its wheels. Direct cooling contributes to the environment friendly, compact design, as properly.
"The Quark is exclusive in its excessive effectivity together with its class-leading torque-to-power-to-rpm-to-weight matrix," stated firm CEO, founder and namesake Christian von Koenigsegg. "This implies, when utilizing the Quark in functions akin to marine, plane or VTOL, there isn't any want for a step-down transmission; as a substitute direct drive may be achieved, because the RPM of the motor is proper from the get-go."
Koenigsegg additional capitalized on the Quark's small, torque/power-dense packaging to create a small, highly effective dual-motor electrical drive it calls the Terrier. Two Quarks sandwich the corporate's David six-phase inverter to create the 670-hp/811 lb-ft torque-vectoring electrical drive, which weighs as little as 187 lb (85 kg). The one inverter dedicates three phases to every motor, eliminating the necessity for a second inverter.
The facility and torque traits of the Quark motors permit to be used of compact, low-ratio planetary gear units within the Terrier, contributing to the small, light-weight design. In flip, Koenigsegg says that the Terrier drive may be instantly bolted to the car chassis, eliminating the necessity for subframe parts.
Koenigsegg imagines the Terrier discovering use in lots of EV functions.
The corporate plans to launch extra particulars about its electrical powertrain parts within the coming weeks. It stated final September that it plans to arrange the Gemera, and the all-new manufacturing facility the place it is going to be constructed, for a 2023 manufacturing begin. It's going to construct a complete of 300 items.
