Why your EV doesn't have the high-tech batteries Koenigsegg is using

The Koenigsegg Regera is a performance hybrid with direct drive, meaning that, off the line, it uses the 664 lb-ft of instant electric torque generated by its trio of electric motors to get going before its 1100-plus-hp, 5.0-liter, twin-turbo V-8 kicks in for the fastest 0–250-mph run one can experience in a car. Having no gears to speak of helps with that; however, the car's high power density requirement called for 384 very expensive lithium-ion cells that give no electric range at all.

 

Koenigsegg's relatively small, 4.5-kWh battery pack is built by Rimac and uses 26700-type lithium-ion cells grouped into six 64-cell modules for 704 electric horsepower that can unleashed without any delay. With the entire system flooded, this compact 145-pound unit is all about its unique cell chemistry, which doesn't mind rapid charging and discharging, or operating at its peek voltage of 806 volts.
