Kia to introduce diesel-hybrid powertrain later this year

By electronically controlling the MHSG using the inverter, the system switches seamlessly between two modes: "motor" and "generator".

The Korean brand's new drivetrain adds a starter motor which doubles as a generator and power supply to deliver 10kW of assistance to the diesel engine in a move which it claims will reduce Carbon dioxide emissions by up to 4% on the new Worldwide harmonized Light vehicles Test Procedure (WLTP), and 7% on the New European Driving Cycle (NEDC). This system, which uses a 0.46kWh 48V lithium ion battery, will eventually make its way into other Kia models. 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. In "motor" mode, under acceleration, it uses battery charge to add torque to the engine to aid acceleration.

The technology will be called EcoDynamics+.

The manufacturer also says that the system will have minimal impact on practicality, with the required 48V battery located beneath the boot floor.

This battery is also able to connect to the vehicle's on-board power supply, meaning the regular 12V battery and the starter motor can be smaller.

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. And while debuting on a diesel engine, it will be adapted for petrol units.

Details of the pricing, performance and specification of the new Kia Sportage SUV have yet to be announced. Kia says that the new powertrain is the first new technology to be launched as part of the brand's wider powertrain electrification strategy.

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.
