Kia to unveil new diesel-hybrid engine in the UK – Powertrain offers lower emissions | Cars | Life & Style
Kia Motors will introduce its first 48V diesel mild-hybrid powertrain in the second half of 2018.
This new powertrain has been designed to reduce CO2 emissions and a cheaper alternative to typical full hybrid powertrains.
Kia’s new ‘EcoDynamics+’ powertrain reduces the amount of CO2 emissions it produces by supplementing acceleration with elector power from an additional 48-volt battery.
It is also said to extend combustion engine ‘off-time’ by using a new Mild-Hybrid Starter-Generator unit.
The carmaker says the technology “offers a compelling cost-to-performance ratio compared to full hybrid powertrains.”
In addition to this the system can also be integrated into existing engine and powertrain architects without it impacting the packaging or practicality of it and will not need recharging.
According to Kia, the system, which is paired with Kia’s Selective Catalytic Reduction(SCR), can reduce CO2 emissions by up to four per cent on the new Worldwide harmonized Light vehicles Test Procedure (WLTP).
It has two different modes – motor and generate – which can modify how the system is used.
In ‘motor’ mode the system provides up to 10kW of electric power assistance to the powertrain reducing engine load and emissions.
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.
The first model to benefit from the addition of the new powertrain is the Kia Sportage later this year, before the all-new third-generation Kia Ceed and other models in the range will be offered with it from 2019.
This new powertrain also forms part of the manufacturer’s strategy 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.
With the negativity surrounding diesel engines, the new hybrid system could be a way for the fuel type’s future to be prolonged, by reducing emissions.
