Koenigsegg Gemera

Specifications

The Gemera marks Koenigsegg’s first venture into a four-seat layout. Its hybrid system relies on a reworked hot-V version of the 5.0-liter twin-turbo HV8 borrowed from the Jesko. On E85 fuel, this HV8 setup delivers a total of 1715 kW and 2750 Nm of torque. The engine connects to a 9-speed Light Speed Tourbillon Transmission, itself a tweaked take on the Jesko’s 9-speed Light Speed gearbox. Koenigsegg had originally floated an alternative hybrid powertrain based on their twin-turbocharged TFG 2.0-liter inline-three, which would have used a direct-drive single-speed transmission. But in July 2024, Christian Von Koenigsegg confirmed that option was dropped due to insufficient customer interest. That three-cylinder engine employed Koenigsegg’s Freevalve technology, meaning it had no camshaft, and produced 600 bhp at 7500 rpm and 600 Nm from 2000 to 7000 rpm, with an 8500 rpm redline. When paired with three electric motors, that configuration would have yielded 1400 hp. The production car includes three electric motors: one for each rear wheel, each rated at 500 hp and 1000 Nm, plus the Dark Matter motor on the front axle, which contributes 600 kW (800 hp) and 1250 Nm. The Dark Matter unit measures 15.1 inches in diameter and 15.3 inches thick, weighing 39 kg. It uses a raxial flux design—an axial flux layout supplemented by a smaller radial flux element to smooth the torque curve and cut torque ripple. Carbon fiber reduces weight in the rotor, stator, and housing, and the motor employs six phases instead of the usual three. An 850-volt, 14 kWh battery pack supplies power. Standard wheels are forged aluminum center-lock units, sized 21 by 10.5 inches up front and 22 by 11.5 inches at the rear; optional Aircore carbon fiber wheels are also available. Standard tires are Michelin Pilot Sport 4S, with street-legal Michelin Cup 2R as an option, both in 295/30 ZR21 front and 315/30 ZR22 rear dimensions. Front brakes use 410 mm ventilated ceramic rotors with six-piston calipers, while the rear brakes have 395 mm ventilated ceramic discs with four-piston calipers, and the car features electric brake boosting.
