The EcoDynamics+ powertrain reduces Carbon dioxide emissions by supplementing acceleration with electric power from an additional 48-volt battery and extending combustion engine "off time" using a new mild-hybrid starter-generator unit.
Kia is introducing EcoDynamics+ 48V mild-hybrid diesel engines to their United Kingdom range later this year in a bid to reduce emissions. The options are 1.7-litre and 2.0-litre units; the latter is more likely to be offered with the boost, in order to create a higher-ranking powertrain. In "motor" mode, under acceleration, it uses battery charge to add torque to the engine to aid acceleration.
The system also allows a moving stop-start function, enabling the diesel engine to switch off automatically during in-gear deceleration and braking.
The technology will be called EcoDynamics+. Depending on vehicle, the 48V battery will be located beneath the boot floor, minimizing the impact on vehicle practicality.
The MHSG is mounted in the engine bay and connected to the crankshaft by a belt.
The 48V battery's DC/DC converter enables the new battery to connect to the vehicle's on-board power supply, leading to a significant reduction in the size of the 12V battery required to power the car's ancillary electronics.
More detailed plans for the roll-out of its new mild-hybrid technology in the United Kingdom will be announced by Kia in due course.
The first auto that will receive this technology, are the Kia Sportage, which will be launched this year.
Kia's EcoDynamics+ diesel mild-hybrid powertrain is compatible with both manual and automatic transmissions, and could be adapted for front-, rear- and all-wheel drivetrain layouts.
Expect to hear more details soon on the Sportage's use of the EcoDynamics+ powertrain, as well as United Kingdom pricing and specifications.
The strategy envisioned by Kia for the electrification of its range BY 2025 includes the launch of five new hybrid cars, five plug-in hybrids, five battery-electric vehicles and, among the few to do so, a fuel-cell electric vehicle sometime in 2020.
