Kia 48V Mild-Hybrid Diesel powertrain rolling out THIS year

Kia Motors is to launch a diesel mild hybrid Sportage later this year: its first vehicle to feature this powertrain technology.

The system incorporates a 48v battery with a starter generator unit, similar in principle to the tech used current vehicles as wide-ranging as the Suzuki Ignis and the Audi A8.

The system makes its debut in the Sportage later this year but will later find a home in the all-new third-generation Kia Ceed and other Kia models from 2019.

South Korean manufacturer Kia is to introduce a diesel-hybrid powertrain to its vehicle line-up to help "reduce Carbon dioxide emissions". The options are 1.7-litre and 2.0-litre units; the latter is more likely to be offered with the boost, in order to create a higher-ranking powertrain. Restarting of the engine is carried out after pressing of the accelerator pedal.

The technology will be called EcoDynamics+. This allows the internal combustion engine to automatically turn off during braking and in-gear deceleration, whereas the MHSG can re-ignite it whenever the driver presses the throttle. Depending on vehicle, the 48V battery will be located beneath the boot floor, minimizing the impact on vehicle practicality. Because the MHSG integrates directly with the engine, driving the crankshaft via a belt, there is little need to repackage the engine bay.

The mild hybrid will be affiliated with both manual and automatic transmissions and will work as described on all types of transmissions: front, rear and all-wheel drive.

More detailed plans for the roll-out of its new mild-hybrid technology in the United Kingdom will be announced by Kia in due course. It can also be adapted for FWD, RWD and AWD drivetrain layouts.

The powertrain is part of the South Korean firm's ongoing electrification strategy that will see 16 "advanced powertrain" vehicles introduced to its line-up - comprising five hybrids, five plug-in hybrids, five all-electric and one powered by fuel cell.
