Kia Sportage To Debut Brand's New Diesel Mild Hybrid Powertrain

Kia Motors is to launch a diesel mild hybrid Sportage later this year: its first auto to feature this powertrain technology. It means the engine can switch off earlier and for longer, even while the auto is moving, and lean on a 13bhp power boost from the motor while accelerating, both of which reduce fuel consumption.

Kia's latest electrified drivetrain follows the brand's announcement of 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 EV.

Kia claims the EcoDynamics+ system will result in much cleaner and more efficient diesel engines, with as much as four per cent less Carbon dioxide emitted on the new Worldwide Harmonised Light Vehicles Test Procedure standard.

The 'EcoDynamics+' powertrain is the first new technology to be launched as part of Kia's wider powertrain electrification strategy.

Compact packaging means the system easily integrates into existing architecture.

"Kia's mild-hybrid powertrain is created to fit seamlessly into consumers' lives, with no plug-in recharging required".

Connected by a belt to the diesel engine's crankshaft, the system offers two modes of operation, motor and generator, switching being electronically controlled.

Details of the pricing, performance and specification of the new Kia Sportage SUV have yet to be announced.

Kia said this technology offers a cost-to-performance ratio compared to full hybrid powertrains and will enable it to offer a cleaner diesel engine.

Kia's mild-hybrid powertrain has been engineered to deliver greater efficiency from internal combustion engines-either gas or diesel.

The system also allows a moving stop-start function, enabling the diesel engine to switch off automatically during in-gear deceleration and braking.

This battery is also able to connect to the vehicle's on-board power supply, meaning the regular 12V battery and the starter motor can be smaller. During in-gear deceleration and braking, the engine will shut down and the hybrid system will kick things back into life if the throttle pedal is pressed. The adoption of the MHSG also means the conventional starter motor can be downsized and used primarily for cold starts at low temperatures, and charge from the 48V battery can help start the engine in most conditions.

Kia hasn't released any specs yet, but says that the 48V battery will be located beneath the boot floor, at least in the case of the Sportage.

The EcoDynamics+ will be eventually adapted for use in petrol engines too, and is compatible with manual and automatic transmissions.
