In a bid to reduce emissions, Kia is delivering a new 48V mild hybrid diesel powerplant to its United Kingdom cars this year (Kia say in the second half of 2018) initially in the Kia Sportage but likely to be offered more extensively across the Kia range.
Kia Motors says EcoDynamics+ mild-hybrid technology offers a compelling cost-to-performance ratio compared to full hybrid powertrains.
According to Kia, the EcoDynamics+ uses a Selective Catalytic Reduction (SCR) emissions control to lower Carbon dioxide emissions by up to four per cent on the new Worldwide Light vehicles Test Procedure (WLTP) and by up to seven per cent on the existing New European Driving Cycle (NEDC).
Kia is preparing to electrify its Sportage with the introduction of a 48V mild-hybrid version of the SUV set to be launched later this year.
The 48V battery DC/DC converter enables the battery to connect to the vehicle's on-board power supply, reducing the reliance on the vehicle's 12V battery required to power the vehicle's ancillary electronics. The starter generator is mounted to the engine via a belt, and provides quick starts-so the engine can remain off when the vehicle is stopped-thereby reducing emissions.
Fastest growing black hole discovered
If this bright black hole would have been in our galaxy, astronomers say that it would outshine all the stars in the sky. If we had this monster sitting in the center of our Milky Way, it would look 10 times brighter than a full moon.
Kia says that the compact packaging of the system means that it'll be relatively straightforward to install in the brand's current model ranges.
In "motor" mode the battery is discharged under acceleration, providing additional torque to the engine for a slight boost in performance under hard acceleration, or to reduce engine load during light acceleration.
Kia says the system can be adapted for front, rear and four-wheel drive vehicles, and will also be adapted for use with petrol engines. The 48 volt generator recharges the vehicle's battery when the diesel engine is running.
The system makes its debut in the Sportage later this year but will later find a home in the all-new third-generation Kia Ceed and other Kia models from 2019.
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.
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. The powertrain will also be adapted for use in gasoline engines.
