Kia Lunching New Mild-Hybrid Diesel Sportage

Kia Motors will introduce its first 48V diesel mild-hybrid powertrain in the second half of 2018. The new “EcoDynamics+” powertrain supplements acceleration with electric power from an additional 48-volt battery and extends combustion engine ‘off time’ using a new Mild-Hybrid Starter-Generator unit.

The Kia Sportage will be the first model to offer the new EcoDynamics+ diesel mild-hybrid powertrain later in 2018. The new third-generation Kia Ceed will be the second among a range of Kia models to offer the new powertrain from 2019.

The EcoDynamics+ diesel mild-hybrid system is paired with Kia’s Selective Catalytic Reduction (SCR) active emissions control technology, reducing CO₂ 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). The roll-out of diesel mild-hybrid technology will contribute to the brand’s global efforts to improve whole-fleet fuel efficiency.

Kia’s mild-hybrid technology features a compact 0.46 kWh 48-volt lithium-ion battery and a new Mild-Hybrid Starter-Generator (MHSG). By electronically controlling the MHSG using the inverter, the system switches seamlessly between two modes: “motor” and “generator”. 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. In generator mode, the system harvests kinetic energy from the vehicle during in-gear deceleration and braking and uses the power to recharge the batteries.
