Hyundai Motor Group’s long awaited electric car platform, the Hyundai E-GMP, was revealed last year and has given the world the Hyundai Ioniq. With the E-GMP set to deliver 23 electric vehicles from the Hyundai Motor Group (Hyundai, Kia, and Genesis) eventually, let’s take a look at 6 lesser known facts of this platform:
Ready for high-performance EVs
Electric is exciting, and at Hyundai Motor Group, the E-GMP platform is set to raise the bar for performance across the entire line-up. The company went for a rear-wheel drive drivetrain layout for this platform for keeping it ready for high-end performance EVs. The E-GMP platform will likely spawn some of the most performance-focused Hyundai, Kia, and Genesis cars ever made in the coming years.
Speaking to CAR recently, Hyundai Motor Group’s R&D chief Albert Biermann said that the company is working on “some more interesting, challenging high-performance applications” of the E-GMP platform, and that is why it decided to have a RWD drivetrain layout. With an additional, front motor, it is possible to have AWD models.
In certain E-GMP models, Hyundai Motor Group will offer a system power of nearly 600 hp, Biermann said. In December last year, the company’s subsidiary Kia announced a high-performance Kia EV with a 0-62 mph acceleration time of less than 3.5 seconds and a top speed of 260 km/h (162 mph). At the CEO Investor Day last month, it revealed that the Kia CV can complete a 0-100 km/h (0-62 mph) sprint in just three seconds.
Safety of the electric drivetrain and components
Hyundai says that in the energy absorption zone, from the back beam to the subframe rear mounting, the vehicle body is built to deform to absorb shocks. However, in the lower support section, from the subframe mounting to the dashboard section, the impacts are minimized on the all new PE (power electric) system, battery and electric module by adopting a collision avoidance structure. Further, ultra high strength steel is used in the high voltage zone where the batteries are located and a hot stamped steel protects the battery area.
Air-conditioning unit moved outside the cabin to create more space
To liberate more interior room, the ‘space consuming’ air conditioning unit is moved outside the car and is placed where the internal combustion engine would be, giving front passengers extra room. Further, the center tunnel at the rear (seen on conventional vehicles) is non-existent thanks to the low mounting point of the batteries. This will also allow various arrangements of the front and back seats for a variety of lifestyle applications, says Hyundai.
All E-GMPs use single type of standardized modules
All Hyundai E-GMP based cars and SUVs will use a single type of standardized battery module which consists of pouch type of cells and the pack itself can be configured as per energy required for each model. This, the company says, has reduced the number of part types by 40 per cent and total number of parts are reduced by 60 per cent.
The Hyundai E-GMP platform supports a ‘first-in-the-world’ multi-charging system which is patented by the company. The system can use old and new generation type fast chargers, but can maintain 800V charging irrespective. It uses the vehicle’s driving motor with the charger to boost 400V to 800V and charge the battery, the company says.
Separate cooling structure to optimize efficiency
Part of the Hyundai E-GMP’s impressive 80 per cent charge in 18 minutes comes thanks to the impressive cooling block structure installed on the drivetrain. Apart from enhancing safety during a coolant leak, it allows energy density to be increased by 10 per cent. A new cooling type of coil on the PE system is integrated with the motor, and sprays lubricant directly from the EV transmission to the motor to reduce heat induced losses, and thus further the range.
