Producing 512hp with maximum torque of 715Nm, the Quant runs 0–100 km/h in 5.2 seconds and hits a top speed of 275 km/h. The all-electric car is powered through a combination of what it has dubbed a Flow Accumulator Energy Storage (FAES), which charges to full capacity in 20 minutes, and solar energy supplied via a thin layer photovoltaic coating over the car. The combined solar/FAES offer a claimed range in excess of 500km.

New technology. The thin layer solar technology and the proprietary FAES system enable the design of a fully electrical vehicle, rather than relying on more commonplace hybrid solutions. This also simplifies the drive train layout and packaging, as only one propulsion system is needed.

Koenigsegg says that the Quant will be able to cover long distances without a charge due to a combination of a low frontal surface area of around 2 m2, a drag coefficient of around CD 0.27 and the efficiency of the FAES and solar systems.
