After the long-range model of the Kia EV6 didn't get off to a good start in a recent range test, the more expensive all-wheel drive variant of the popular EV from South Korea has now also struggled to reach its official EPA range at highway speeds of around 70 mph.

If EV cars are anything like laptop when it comes to battery, you can still divide the numbers from the test by 2 IRL
I never ever got anywhere close of the battery life given in test reports (notebookchekck included) when it comes to all the laptops I ahve owned
This is an apple to oranges comparison and is meaningless.
EPA combined range test is " the approximate number of miles that a vehicle can travel in combined city and highway driving (using a mix of 55% highway and 45% city driving) before needing to be recharged,"
So EPA estimates are closer to a real world daily driver scenario. Not a 70 MPH road trip.

I beg to differ. As a prospective buyer of this EV, I'd very much like to know how much the range drops at 70 mph. As you already noticed, there's no separate EPA highway range estimate for this specific car, which means that real-world tests like these are anything but "meaningless".
I agree that a 70 mph range test is not meaningless, especially for long distance EV drives, but it is an apples to oranges comparison with the basic EPA range number that includes city driving. However, you can easily see what the EPA says the highway range should be for any vehicle. Just go to fueleconomy.gov, Compare Side-by-Side, choose your vehicle(s), and then click the "Personalize" link toward the bottom of the comparison view. Change your % miles in stop-and-go traffic to 0 and click the Personalize button to get an all highway range. Using this method, a 2022 Kia EV6 AWD (Long Range) shows an EPA rated 242 all highway mile range which is now comparable to a 70 mph range test. Of course, variables like HVAC use, mountainous terrain, ambient temps, etc. also come into play.

Correct. Their comparison to EPA is misleading. The data point is useful, though, for the occasional person who can drive 250 miles at 70 mph.
I'm lucky to average above 45 mph in real world highway driving over 8 hours on a 65 mph road. And when doing that, the AWD EV6 can easily exceed 300 miles (I own one).
In real world commuting and errand running; 11 miles over 60 minutes, the range is more like 325 miles, though not a scenario where I need to worry about charging, either.
You could work backwards from the EPA MPGe, for which they provide both city and highway measured data. The EPA also gives the ratio of city to highway in determining the estimated range. I've gone through the process, and nothing adds up.
Well, a full highway trip would probably use more battery and since a good 10% probably comes from the constant regerating breaking u do in city driving... I think it sounds about accurate
Toți: EV range is nothing like laptop battery life. Hyundai and Kia sandbag significantly.
My Kona was supposed to have 450km range and I can easily get 550. Just not driving 70mph on the highway, rather 55-60.

That entirely depends on what you're doing. If you tow a trailer or have bicycles on the roof, yes, you might just as well cut the range in half. Especially when you drive fast (I've got trailers and racks rated for 130 km/h). Aerodynamics matter hugely. If you drive like it's prescribed in the test, you should be fine. IMHO EPA gives reasonable estimates.
I own a first edition (1278), which is basically a gtline with 20 inch wheels, i have been driving to ,Baltimore, DC, Norfolk (from Philly)generally averaging 70 mph (often 80) and I get about that 245 range, lm sure under perfect conditions and averaging 50 mph with ac fan at 2-3 power and driving in econ mode you could get 275 miles
