[Brioniq]

I had to take a trip for work yesterday - North of Sheff to Coventry, 95 miles each way so a 190 mile round trip.
My spring/summer average for the last 5000k miles is showing 5.8 mpkWh and the car's indicated range was 210+ miles so I thought I'd give the Ioniq 38.3 a go.

Being slightly beyond the range comfort zone (and importantly, on works time) I thought I'd try hypermiling it to be sure of success: Adjusting route to avoid hills and reduce distance going through Sheffield, flow driving techniques, tyres 2psi overinflated, 62mph motorway, naughty slipstreaming large vehicles, but not ludicrously close. Conditions were close to ideal; dry, temperature in the teens °C, roads uncongested.

Ended up using 36% on the way there and 37% on the way back, so 27% remaining after a 190 mile motorway trip.
Indicated trip efficiency was 6.8 mpk.
Extrapolated, the range would be 260 miles 100 - 0%.

Keen to hear all about yours' efficiency (especially if it beats this in some way)!

August this year, pootling around Norfolk fens, visiting Beccles etc on holiday. wih my wife. probably didn't exceed 45mph on this little ramble! Nice hot sunny weather, ideal conditions.
No hypermiling techniques needed, wasn't much traffic at all so easy to go v gently w/o upsetting anyone.
38.3 kWh * 7.0 extrapolates to 268 mile range estimated.

Well done I doubt I could achieve or better that, my accumulated efficiency has been stuck on 5.7 mi/kWh for months now.

Did a gentle drive the other day and drove 48km from 100% to 91%. This would have given us a range of 530km lol if the percentage is to be believed. Round trip back to home so no change in overall elevation.
9.4 does not addup with these two figures.

9.4kWh/100km = 6.6mi/kWh.

But by the percentage and distance it is closer to 7.0mi/kWh

GOM is now back up to its spring range.

Nice going!

Remarkable efficiency, very well done!
Surely it'd be Helium-filled tyres needed to improve on that?😁

Hi everyone. I'm still yet to purchase a 38kwh ioniq, but basing your efficiency figure and your types of driving I can see, I can't wait to get one. Ive always got good mpg out of most cars, matching or exceeding the official mpgs. I had a focus 1.0 ecoboost that got 65mpg regular. Now got Mondeo diesel 2.0 and get 75mpg. It's just the drive to work and back along rural quiet roads that enable this.
So I'm sure I could be up there with the rest of you when I've got an ioniq electric.

yeah August was a good econo-month, I'm down to 8 km/kWh now

That is impressive I had one of those but rarely got any more than 32 mpg on mixed motorway and town driving?
Good luck with your hunt for an Ioniq

After a couple of long holiday trips this summer with my 38kWh in good weather and flat landscape, I have realized that speed is the greatest enemy. As long as you stay between 60-70km/h (37-43mph) on small winding roads without hurry, you can drive efficiently! Also found a "certificate of authenticity" among the car's papers, which also states the range in city traffic, max 50km/h (30mph)? to 412km (256miles).

These stats are impressive, but not as good as mine. I paid extra for the 'perpetual motion' upgrade when I bought mine, so mine doesn't use any energy at all.

(ok, so the fact that I live at the top of a big hill might help a little )

You need to claim your money back from the dealer! Despite this gizmo, you still only get about 182 mile range!!

Speaking of hills, found a German guy on Youtube who goes up from Berchtesgaden to Örnnästet (Kelsteinhaus) 1500m.a.s.l.
On the way down, a drop of 1000 meters in height, the 38 regenerates 7% battery charging in 11km.
Unfortunately you don't see the screens in the car before he starts climbing, otherwise you could see what the energy consumption to get up was, he only mentions the consumption 14.5kWh in one place, but he might have found the Perpetuum Mobile .
Running out of charge, just find a hill and drive up and down 10 times...

What are your rule for hypermiling? I try to follow those

• try to avoid high speeds
• try to avoid any hard breaks (better reduce speed early to gain time)
• use higher tire pressure
• avoid twisty country roads because each acceleration, e.g. after a bend, costs energy - prefer (slower) highway (between lorries)
• try to avoid higher accelerations
• in the Winter prefer seat/steering wheel heating over cabin heating, unless the windscreen fogs

I've found and bought an ioniq on Friday
My journeys to and from work are currently getting up to 6.4miles/kWh. Not a bad start but should be able to improve. Other journey a bit less. Overall is 5.6miles/kWh , done 113 miles since full charge and showing 100 miles left.

 

[SleeperPService]

I could brag about this one but our actualconsumption was no where near this and it was over two days. It was almost double this as we were heading into a 30-40kph headwind which was disconcerting for a 230km leg.
