This new powertrain has been created to reduce Carbon dioxide emissions and a cheaper alternative to typical full hybrid powertrains.
The mild-hybrid starter-generator also extends combustion engine "off time" by shutting down the engine when coasting to a halt, rather than waiting until the vehicle is stopped like most start-stop systems.
The Korean company is yet to confirm which of the diesel engines offered in the Sportage will be mated to the mild hybrid system.
Kia claims that the compact nature of the EcoDynamics+ means the technology can be integrated into existing vehicle and powertrain architectures without impacting practicality or packaging. There'll be a mode for harnessing energy released during braking to recharge the 48v battery and a "moving stop and start" function that can switch off the engine as you're slowing down, before the vehicle has come to a complete halt.

The widely expected move comes as Fox tries to complete the Disney deal, which involves selling about $US52 billion ($65 billion) of entertainment assets.
Kia Motors is to launch a diesel mild hybrid Sportage later this year: its first vehicle to feature this powertrain technology.
The mild hybrid system will eventually expanded for use beyond just diesel engines, which means that we'll likely see it bolted onto a gas engine in the U.S.in the not too distant future.
While some automakers have started ditching oil burners completely, others, such as Kia, continue to invest in new technology that helps diesels improve fuel economy and emit less CO2.
Kia's mild-hybrid powertrain has been engineered to deliver greater efficiency from internal combustion engines-either gas or diesel. Under deceleration, or when driving downhill or coasting towards a stop light, the MHSG switches to "generator" mode, recuperating energy from the crankshaft to recharge the battery. The MHSG can then seamlessly re-ignite the engine - in any situation - if the driver presses the throttle pedal.
The system is compatible with both manual and automatic transmissions vehicles, and could be adapted for front or rear wheel drive, or all-wheel drivetrain configurations.
