KIA chose the Geneva Motor Show to reveal all-new ‘mild hybrid’ powertrain using an electric supercharger to simultaneously reduce emissions and improve engine performance in KIA’s next-generation models.

Developed by Kia’s European R&D centre in Russelsheim, Germany, the new hybrid system uses a 48 volt lead-carbon battery that powers a small electric motor to increase the engine’s power output and cut exhaust emissions. Lead-carbon batteries were chosen in preference to lithium-ion equivalents as they require no active cooling, are more easily recyclable at the end of the vehicle’s life and can function much more efficiently in sub-zero temperatures.
