Kia to launch EcoDynamics+ diesel mild-hybrid powertrain in Sportage SUV

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

A mild-hybrid diesel variant of the Kia Sportage SUV will go on sale before the end of 2018. The new third-generation Kia Ceed will be the second among a range of Kia models to offer the new powertrain from 2019. Connected by a belt to the diesel engine's crankshaft, under acceleration the MHSG provides up to 10kW of electric power assistance to the powertrain in motor mode, reducing engine load and emissions.

The mild-hybrid itself is comprised of a 0.46 kWh 48-volt lithium-ion battery and a starter-generator unit.


The added benefit of the tech is that when coasting towards a junction, the duration of the "stop" part of a start/stop system can be extended, which further helps to reduce fuel demands from the engine.

Kia says the system can switch between two modes, called "motor" and "generator".

A spokesman for Kia Motors said: "In-line with Kia's aim to create innovative cars that are affordable for a broad range of buyers, EcoDynamics+ mild-hybrid technology offers a compelling cost-to-performance ratio compared to full hybrid powertrains".


The first vehicle to get the combustion-electric combo - the mild hybrid will be mounted under the boot floor - will be the Sportage which will be launched later this year.

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.

The company's plan is to launch 16 "advanced powertrain vehicles by 2025", including 5 EVs, 5 PHEVs and 5 hybrids, in addition to a new FCV in 2020. It can also be adapted for FWD, RWD and AWD drivetrain layouts.
