Hyundai Ioniq 5 Vs Kia EV6: EPA Range/Efficiency Numbers Compared

The U.S. Environmental Protection Agency (EPA) recently released range and efficiency numbers for the two upcoming all-electric models, the Hyundai Ioniq 5 (see here) and Kia EV6 (see here).

Both are based on the same Hyundai Motor Group’s E-GMP platform with an 800 V battery system, with an option of single motor, rear-wheel-drive and dual-motor, all-wheel-drive system.

EPA has released the ratings for both the smaller and bigger battery options of both cars, although as far as we know, the Hyundai Ioniq 5, at least initially, will be available only with the bigger battery option.

In this post we will compare corresponding versions of both models, side-by-side, to see whether there are substantial differences in range and energy consumption. We assume that all ratings are for 19″ wheel options, but it’s not specified in EPA documents.

If we check the entry-level versions of both models (both have basically the same battery capacity – the 0.2 kWh difference might be associated to rounding differences by Kia), it will turn out that the Kia EV6 has some 5.5% (12 miles) more EPA Combined range. It’s also more efficient by over 6%.

We assume that the differences are mostly associated with aerodynamics and weight of the two cars.

In the case of the Long Range versions (rear-wheel-drive), the differences in range and efficiency are smaller – above 2%. It’s a very small value that probably will not be noticeable by an average user.

The Kia EV6 also appears to have a different power output – 160 kW compared to 168 kW in the Hyundai Ioniq 5.

Interestingly, in the case of the top-of-the-line versions, the range and efficiency differences are as high as 7% or 18 miles. There is also a small change in the power output.

The two cars appear to be so close to each other in terms of specs that customers are expected to decide which one to choose mostly on the exterior and interior design, brand, utility and prices.

We are eagerly waiting for the final detailed specs and prices of both models, and the market launch in the U.S., which will enable us to conduct range and charging tests on both models.
