EcoDynamics+ reduces CO2 emissions by 4%, to be installed in Sportage
Kia Motors is set to introduce its first 48V diesel mild-hybrid powertrain in the second half of 2018.
To be installed on the Kia Sportage, the new powertrain will reduce the CO2 emissions by 4%.
In line with the Korean car maker’s objective to create innovative and affordable cars, the new EcoDynamics+ mild-hybrid technology offers a compelling cost-to-performance ratio compared to full hybrid powertrains. The compact nature of the components means the technology can be integrated into existing vehicle and powertrain architectures without impacting practicality or packaging.
The introduction of the new 48-volt powertrain makes Kia the first car manufacturer to offer consumers hybrid, plug-in hybrid, battery-electric and 48-volt technology across its model line-up. The company also plans to launch 16 advanced powertrain vehicles by 2025, including five new hybrids, five plug-in hybrids, five battery-electric vehicles and – in 2020 – a new fuel-cell electric vehicle.
Kia’s EcoDynamics+ diesel mild-hybrid powertrain will offer cleaner diesel engines. Its system is paired with the brand’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.
The mild-hybrid technology features a compact 0.46 kWh 48-volt lithium-ion battery and a new Mild-Hybrid Starter-Generator (MHSG). When connected to the diesel engine’s crankshaft, the MHSG provides up to 10 kW of electric power assistance to the powertrain in ‘motor’ mode, and reduces engine load and emissions.
Meanwhile, if the MHSG is 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.
Kia’s EcoDynamics+ diesel mild-hybrid powertrain fits both manual and automatic transmissions, and could be used for front-, rear-, and all-wheel drivetrain layouts, and is also compatible in gasoline engines.
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.
