Quark motor size "compact 12 x 13 x 4.4-in (303 x 334 x 112-mm)"
"Two Quarks sandwich the company's David six-phase inverter to create the 670-hp/811 lb-ft torque-vectoring electric drive, which weighs as little as 187 lb (85 kg). The single inverter dedicates three phases to each motor, eliminating the need for a second inverter."
