HYUNDAI Motor Group (HMG) has revealed and detailed its all-new modular electric-vehicle (EV) platform which is about to ship as much as 500km of vary and underpin a myriad of fashions starting from small sedans proper the best way by means of to massive SUVs.
Recognized formally as E-GMP, the brand new structure will make its first market look subsequent 12 months below the Ioniq 5 SUV earlier than happening to underpin 11 different new EVs as HMG marches in direction of its aim of launching 23 new battery-electric automobiles by 2025.
Whereas the platform’s modularity permits it to be tailor-made for a wide range of sizes and segments, it’s going to even have the capability to assist high-performance variants with the present deliberate flagship touted to develop virtually 450kW and dispatch the 0-100km/h dash in lower than 3.5 seconds.
Based mostly primarily round a rear-wheel-drive configuration, the E-GMP homes its batteries between the entrance and rear axles like most different fashionable EV platforms with minimal overhangs and a comparatively lengthy wheelbase afforded by the compact nature of electrical motors.
Prospects can even have the ability to go for all-wheel drive which sees one other electrical motor added to the equation, this time mounted on the entrance axle with the one issues linking the 2 ends being the naked chassis and physique, permitting for a totally flat cabin ground.
No matter drive configuration, all E-GMP-based automobiles will experience on a complicated five-link rear suspension set-up, by means of the center of which runs the world’s first built-in drive axle which mixes wheel bearings with the drive shaft.
The outcomes based on HMG are enhanced experience consolation and dealing with, the latter of which is little question aided additional by the platform’s low centre of gravity.
When it comes to the batteries, HMG says it has been in a position to standardise the design for seamless integration into the assorted deliberate future fashions with the packs being essentially the most power-dense system the group has ever produced, being a claimed 10 per cent extra energy-dense “in comparison with present EV battery expertise”.
This additional vitality density mixed with enhanced cooling additionally permits for increased vitality charging and due to this fact quicker charging occasions with the system in a position to be charged from zero to 80 per cent in 18 minutes when utilizing a 350kW quick charger.
For individuals who don’t have 18 minutes to lose, 100km of vary might be added after simply 5 minutes.
In one other world-first, the platform additionally affords 400V/800V multi-charging with bi-directional capabilities which means the E-GMP-based automobiles ought to have the ability to play an element within the more and more widespread vehicle-to-grid schemes.
“E-GMP is the end result of years of analysis and improvement and brings collectively our most cutting-edge applied sciences,” HMG senior vice-president of auto structure improvement centre Fayez Abdul Rahman mentioned.
“Our BEV line-up will evolve and be strengthened by this revolutionary new platform.”
Relatively than depend on aerodynamics to make sure a satisfactory driving vary, HMG says it selected to give attention to mechanical effectivity so to keep away from its upcoming fashions wanting too much like the present crop of EVs in the marketplace.
Talking to worldwide media on the debut of the E-GMP, HMG head of analysis and improvement Albert Biermann mentioned focusing purely on aerodynamics ends in a bland market selection when it comes to styling.
“In contrast to the youthful rivals within the EV enterprise, on a few of our fashions we’re not focussing a lot on aerodynamics as a result of in case you simply give attention to aerodynamics, then all of the vehicles form of look the identical, and you’ll see that on the street already,” he mentioned.
“When our E-GMP automobiles come on the street subsequent 12 months you will notice improbable designs and utterly differentiated and current entire new design tales.
“We are able to afford perhaps not the class-leading aerodynamics as a result of we’ve such a really environment friendly PE system and that in fact is a problem; to maintain the entire car effectivity.
“We’d have been much more environment friendly on some automobiles however we gave excessive precedence to the styling, to the design of the automobiles.”
The ‘PE system’ Mr Biermann referred to is the platform’s ‘energy electrical’ system which encompasses an electrical motor, EV transmission and inverter all into the one module.
In line with HMG the electrical motor is ready to rev 70 per cent quicker than present models whereas additionally being lighter and extra compact whereas the inverter energy module options silicon carbide semiconductors, boosting effectivity by between two to 3 per cent.
One of many trump playing cards held by the all-wheel-drive variants is the power to disengage the entrance axle’s transmission when most energy or grip isn’t wanted.
Whereas the E-GMP has been singled out because the front-runner amongst HMG’s EV plans, the group has additionally stipulated that EVs derived from the traditional-powered fashions in its vary will proceed to be provided based mostly on the identical platform as their inside combustion siblings.
