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

Kia Ceed The Car Expert

The powertrain, dubbed EcoDynamics, will reduce Carbon dioxide emissions of the Sportage by aiding acceleration with electric power from its additional 48-volt battery, and using a mild-hybrid starter-generator (MHSG) unit to extend the time that the diesel engine is not under load.

Kia Motors will introduce its first 48V diesel mild-hybrid powertrain in the second half of 2018.

Details of the pricing, performance and specification of the new Kia Sportage SUV have yet to be announced. On most vehicles the battery will be located under the boot floor minimising any space penalty. It will be followed by the third-generation Kia Ceed in the early months of next year. When decelerating, and inverter switches the current of the motor, effectively turning it into a generator to top up the 0.46kWh battery.

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.

The MHSG is mounted in the engine bay and connected to the crankshaft by a belt.

The mild hybrid will be paired to both manual and automatic transmissions and will work as described on all types of drivetrain layouts - front-, rear- and all-wheel-drive.

The EcoDynamics+ diesel mild-hybrid system is paired with Kia's Selective Catalytic Reduction (SCR) active emissions control technology, reducing Carbon dioxide emissions by up to 4% on the new Worldwide harmonized Light vehicles Test Procedure (WLTP), and up to 7% on the New European Driving Cycle (NEDC).

Expect to hear more details soon on the Sportage's use of the EcoDynamics+ powertrain, as well as United Kingdom pricing and specifications.

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.
