Building electric vehicles on a platform designed specifically for electric vehicles offers a number of advantages over trying to fit a battery pack and electric motors into a vehicle designed for an ICE. Designers have much more leeway in arranging both the interior space and the vehicle as a whole, for example. And since they are not trying to evolve a new type of vehicle from an obsolete version, they can better optimize the performance, safety measures and range of the vehicle based on the specific driving conditions provided by a electric vehicle.

Company executives were also careful to emphasize the modular and standardized nature of the E-GMP platform, which should not only help reduce the complexity of building these vehicles, but also allow companies to build a wider variety of styles – from bloated coupes capable of zero to 100 km / h in under 3.5 seconds to quieter sedans, wagons, SUVs and CUVs.
The E-GMP itself is designed like other EV platforms – with its battery down to improve center of gravity and, therefore, cornering performance – but with a number of new and innovative features. These include the “world’s first mass-produced Integrated Drive Axle (IDA) that combines wheel bearings with the driveshaft to transmit power to the wheels,” according to a press release on Tuesday.

In addition, the E-GMP is able to reduce the additional energy density by 10% compared to existing electric vehicles thanks to its steel-reinforced battery packs, thanks to an improved heat management system. This improves both performance and range while freeing up a little more legroom in the cabin. Perhaps the most impressive are the E-GMP’s drive motors. They’re smaller than those typically used in other electric vehicles, but they spin up to 70% faster than their larger counterparts, giving you the same level of performance while saving space and weight. Oddly enough, vehicles based on E-GMP will not have a front-wheel drive option – they will be rear-wheel drive by default and 4-wheel drive as an option with the addition of another motor to the front axle.
The E-GMP’s charging system is also quite impressive. The current generation of EVs are typically built on a 400V electrical system, which allows them to recharge at a speed of 50kW to 150kW. But the future Lucid Air, the GM EV Hummer, and a handful of other luxury electric vehicle brands have already embraced an 800V architecture that allows level 3 DC fast chargers to literally feed power back into depleted batteries until the end of the day. to 350 kW. The E-GMP does the same, offering an 800V architecture that can be reduced to 400V if the load situation demands it, and without the need for additional adapters. These will be the first vehicles available capable of recharging at 400V or 800V. HMG expects a vehicle built on the E-GMP platform to have a range of around 500 km, be able to recharge “80 percent in just 18 minutes and can add up to 100 km of battery life in just five minutes. ” Hyundai has already partnered with EV charging network, Ionity, for service in Korea and Europe and is reportedly in talks with US charging networks.

In addition, these vehicles will be able to offer two-way charging, which means they can either draw power from the grid to replenish their batteries, or reject the energy from their batteries back to the grid during peak hours and outages. . It can even power a second electric vehicle (similar to gas siphoning) or serve as a mobile power source on your next glamping trip. In fact, companies estimate that such a vehicle could produce “3.5kW of power and run a mid-size air conditioner and 55-inch television for up to 24 hours.”
HMG plans to deploy the first E-GMP-derived vehicles next year with the release of the Ioniq 5. Stay tuned to Engadget for more details on pricing and availability in the coming months. .
