Hi Everyone,
I have a first generation 2016 28kw ioniq full Ev and have a question about range as I fully charged yesterday showed 144 miles had a journey that was 94 miles ( Giving me a 50 mile leeway ) was a motorway drive and was expecting to lose abit of mileage but as I got to the last 20 miles of the journey I only had 15 miles left I was driving without heating or main lights on only thing that was on was the radio I kept to the 70mph Limit and about 10 of that was 50-60mph so I’m just wondering if this is normal for this amount of mileage loss?

kind regards on any answers
John

There's loads of possible explanations. Things like wind, rain, and temperatures outside can make a big impact on your efficiency. As can hills too.

Using things like cruise control can sometimes harm your efficiency too. If you have an economical driving style then you can likely do better yourself.

Driving at 70 is far from the ideal speed in an EV and you would definitely go further on other roads.

Your numbers don't sound great, but at the same time it's not impossible to believe when you're in a car with a relatively small battery. Unless you're being especially careful I don't think I'd be aiming for more than 100 motorway miles in an Ioniq 28 myself anyway.

It’s been more than 2 years since I had my Ioniq BEV, but from the advertised range of 174 miles, I’d banked on getting 150, but actually achieved around 120.

So if you were pushing it to 70mph for any length of time, I wouldn’t dispute the figures you are quoting.

My Ioniq 28 will also show 145 miles after a few days of local driving and rural bimbling followed by a 100% fill. That simply reflects the normal 5.0 miles per kWh that I can easily achieve in these warm dry weather conditions. But I would never attempt a 70mph motorway trip beyond 90 miles without planning a charge somewhere. Still possible if the speed is dropped to 65 mph but I would only expect to arrive with a handful of miles left.

The key is to ignore the GOM and instead keep an eye on the miles per kWh display. In the 94 miles trip mentioned I would drive at a speed and style to keep that figure at no worse than 3.5 to be sure of getting there, but actually aim for 4.0 miles per kWh for safety.

Backing off on speed on such marginal journeys can be better than driving faster and then will take less time overall than having to stop somewhere for 1/4 hour to grab enough juice to be sure of getting there. And less stressful. Especially if you have passengers to consider.

Ok thanks for the info everyone I didn’t use the cruise also but I was expecting some loss of mileage just not that much lol well I’m learning still and will tread more lightly on the motorways from now on once again thanks to everyone for the feedback and information

kind regards

I've enjoyed my first generation Ioniq SE Premium BEV (28kw) for 10 months now and regularly get 145-150 range when 100% charged (once or twice a month for longer journeys). Most of my driving is local so I normally charge to 80% which gives me app 115-125 mile range. Like 80698 says, an economic driving style can enhance your range(!) I don't deliberately avoid motorways, but tend to stay in the left or middle lanes if I do and safely keep around 62-65 mph which helps extend the range. I did notice that my figures will regularly drop some 15-20% over colder winter periods, even with judicious use of heating, etc.

To more fully appreciate 'the EV experience', I would politely point out the benefit of mastering the use of the paddles to control regenerative braking and utilize 'Regen 0' safely to safely control 'Coasting', which uses absolutely no power at all from the battery!
