Kia says the new powertrain makes it the first manufacturer to offer mild-hybrid, conventional hybrid, plug-in hybrid and fully electric vehicles, with a fuel-cell electric vehicle set to follow in 2020. The new third-generation Kia Ceed will be the second among a range of Kia models to offer the new powertrain from 2019.
Kia says that its mild-hybrid technology can provide extra acceleration for overtaking, as well as reducing engine load when the auto is being driven more gently.
Compact packaging means the system easily integrates into existing architecture.
The Korean auto maker has confirmed a new 48-volt battery with starter generator unit will feature on vehicles in Europe from this year, beginning with the Sportage SUV. By electronically controlling the MHSG using the inverter, the system switches between two modes: "motor" and "generator".
Huge discovery about Lost asteroid stuns scientists
The Cheliabinsk meteorite measured no more than 20 meters when it entered the atmosphere over Russian Federation in February 2013. Nearly eight years later, astronomers realized that an asteroid they temporarily called ZJ99C60 was actually 2010 WC9 returning.
Full prices and specs for vehicles fitted with the new powertrain are yet to be confirmed.
That all translates to greater efficiency, additional torque for hard acceleration and reduced engine load during light acceleration. It can even deliver a "Moving Stop-Start" if there's enough charge in the battery. During in-gear deceleration and braking, the engine will shut down and the hybrid system will kick things back into life if the throttle pedal is pressed.
Kia hasn't released any specs yet, but says that the 48V battery will be located beneath the boot floor, at least in the case of the Sportage. And because the 48V battery connects to the car's on-board power supply it means a smaller 12v battery and starter motor. Charge from the 48V battery helps to start the engine in most conditions.
Kia will communicate more detailed plans for the roll-out of its new mild-hybrid technology in the coming months.
