IN PARALLEL with ongoing totally electrical car and battery growth, Hyundai Motor Group (together with Kia and Genesis) has unveiled a subsequent technology hybrid powertrain system it says delivers a brand new customary for energy and effectivity.
The transmission-integrated system was debuted not too long ago at a Hyundai Motor Group (HMG) occasion known as ‘Subsequent-Gen Hybrid System Tech Day’, highlighting the South Korean producer’s considerably enhanced hybrid know-how, which “will enhance the driving and possession expertise of future Group merchandise, delivering customer-focused advantages”.
The powertrain makes use of a brand new easy shifting transmission with two built-in motors that may be paired flexibly with a variety of inside combustion engines, permitting for optimised efficiency and gas effectivity throughout a variety of auto lessons.
Utilizing the know-how, HMG plans to supply a variety of industry-leading new merchandise throughout the hybrid car house together with a brand new Palisade giant SUV due quickly.
“Moreover, numerous electrification-focused applied sciences have been integrated into the next-generation hybrid system to boost driving efficiency, refinement and trip consolation,” HMG stated in an announcement at its tech’ presentation.
Delving a little bit deeper into what makes the most recent “twin motor” HMG hybrid system tick we discover the transmission features a new P1 motor that handles beginning, battery vitality technology and vitality deployment to help propulsion and a P2 driving motor liable for propulsion and regenerative braking.
Designers have built-in the dual-motor setup to enhance energy, efficiency and gas effectivity whereas reaching easy shifting and diminished noise and vibrations for a extra refined driving expertise.
It may be paired flexibly with inside combustion engines throughout HMG’s line-up, delivering a system output from the low-73kW vary to the mid-220kW vary permitting for broad utility from sub-compact to giant automobiles.
HMG tapped its intensive expertise with hybrid powertrains and motor and battery management know-how accrued by growth of its BEV-dedicated, E-GMP electrical car platform to boost driving efficiency and luxury.
Many comfort options corresponding to Keep Mode, Car-to-Load (V2L) performance, and Sensible Regenerative Braking integrated within the hybrid system are lifted from the corporate’s BEVs.
To completely capitalise on the subsequent gen’ know-how, HMG additionally improved ICE design with superior compression and injection methods to extend effectivity.
We received’t have to attend lengthy to see the fruits of HMG’s labours as the primary powertrain to make use of the next-generation hybrid system is in new Hyundai Palisade and makes use of a redeveloped petrol 2.5-litre turbo hybrid unit that enhances the design and management know-how of the prevailing engine to maximise effectivity.
A petroleum 1.6-litre turbo hybrid powertrain may also be obtainable later.
Engine designers reassigned the two.5 engine’s beginning and producing duties to the newly added P1 motor, the turbo hybrid powertrain minimises energy losses.
“Mixed with enhanced cylinder movement throughout the engine and the adoption of a high-efficiency cycle optimised for hybrids, gas effectivity has been improved,” the corporate says in an announcement.
“Moreover, an improved piston design and a considerably expanded triple gas injection vary enhances combustion pace, stabilises combustion and suppresses detonation, enhancing engine effectivity additional nonetheless.
“By connecting the P1 motor on to the engine, the system reduces engine begin time. Exact management of engine load and the driving pressure of the P1 and P2 motors be sure that the engine operates inside a high-efficiency vary, enhancing gas effectivity.”
HMG says the petrol 2.5 turbo hybrid system used within the all-new Palisade delivers most gas effectivity of seven.1 litres per 100km, a most system output of 245kW, and most torque of 460Nm, providing roughly 45 per cent larger gas effectivity, 19 per cent extra most energy, and a 9 % enchancment in most torque in contrast with a 2.5 turbo petrol mannequin.
“The subsequent-generation petrol 1.6 turbo hybrid improves gas effectivity by greater than 4 per cent in a mid-size SUV in contrast with earlier fashions, rising the system’s most rated torque output from 367Nm to 380Nm and enhancing acceleration response,” Hyundai added.
Alongside the next-generation hybrid powertrain, HMG plans to combine superior electrification applied sciences to boost efficiency, effectivity and competitiveness in its new hybrid automobiles together with Electrical All-Wheel Drive (e-AWD), Electrification-Car Movement Management (e-VMC 2.0), e-Dealing with 2.0, Electrification- Evasive Dealing with Help (e-EHA 2.0), e-Journey 2.0, Keep Mode, V2L and Sensible Regenerative Braking.
Different new applied sciences revealed on the HMG System Tech Day embrace Hierarchical Predictive Management (HPC) and Sensible Regenerative Braking, each enhancing gas effectivity.
The previous optimally controls battery cost by predicting the driving route and street circumstances, choosing the right driving mode (e.g. EV, hybrid, regenerative braking mode and so on.) alongside the route for improved gas effectivity whereas the latter routinely applies optimum regenerative braking pressure based mostly on navigation information and distance to different automobiles forward, lowering brake pedal inputs and rising battery cost by regenerative braking to additional enhance gas effectivity.
“We now have developed an modern new hybrid system that integrates our long-accumulated engine, transmission and hybrid system growth expertise with the electrification know-how utilized to our world-class electrical automobiles,” stated Hyundai Motor Group government vice chairman and head of electrified propulsion take a look at centre Dong Hee Han.
“We are going to proceed to develop modern applied sciences that actively utilise electrification capabilities throughout the transition to EVs, offering prospects with eco-friendly automobiles that supply superior efficiency.”
