Hyundai Group will use lighter and more efficient EMR4 electric motors

The Hyundai Group has established itself as one of the great protagonists of global electric mobility. With its increasingly large range of electric vehicles, the South Koreans do not cease in their efforts to improve products that are already taken as a reference. With an eye on the years to come, The Hyundai Group and Vitesco have signed an agreement by which the automaker will mount the new and most advanced electric drives of the German companythe new EMR4 engines.

With a contract valued at more than 2,000 million euros, we will see the first vehicles to have the new engines from 2024. Intended for the global B and C segments, Hyundai and KIA are already working on the development of their new models. The Asian conglomerate will use 3-in-1 engines with 160 kW of power (218 hp), thus exceeding the performance of current units that do not exceed 150 kW (204 hp). The EMR4 blocks will replace the EMR3, improving autonomy and performance figures.

Although Hyundai Group’s E-GMP platform works at a voltage of 800 volts, EMR4 motors only run at 400 volts so Vitesco will provide the attached invertersalthough these will not be used throughout the range, since Hyundai and KIA have reiterated at all times that they will use 400-volt schemes for some of their models, mainly in the B and C segments. Just the first to use the new propellants to from 2024.

The new EMR4 engines offer a power range between 80-230 kW (109-313 hp).

Although Hyundai and KIA will only offer the EMR4 block in a medium power range, thanks to its new specifications, Vitesco was able to cover a power range between 80 and 230 kW with its new engine, between 109 and 313 horsepower. A range much higher than that currently offered by EMR3 motors that range between 120 and 150 kW. This is not the only gain, since a reduction in the block size is also achieved, which makes integration easier, and also a better efficiency, which should translate into an increase in autonomy.

The improvement in performance and efficiency is achieved through the use of semiconductors made of silicon carbide (SiC). The smaller size also translates into less weight, up to 25% compared to EMR3 blocks. With different configurations available, either with power inverter or with more or less power, all EMR4 thrusters will be manufactured on the same assembly line, mainly in the Chinese plant that Vitesco Technologies has in Tianjin, in addition to other locations.

Of course, both parties have been delighted with the agreement signed: “We are proud to contribute to Hyundai Motor Group’s next electric vehicle platform with this attractive driveline,” said Andreas Wolf, CEO of Vitesco, during the presentation and signing ceremony. “This order confirms us once again in our strategy with a very early focus on electric mobility.”
