Take that EPA!

First time poster here. I had to share this since so many reviewers trash the range of the GT based on the EPA rating without giving the car a real world chance. I have been watching the range increase the longer I own the car. I drive mostly in Normal mode with occasional GT blasts. Lately I have been driving a little more conservatively to see what kind of range I can get. Yesterday I charged to 100% since I was going to drive about 100 miles and wanted to test it. I drove 53 miles out and 53 back for a total of 106 miles and came home with 62% battery and 166 miles of range left, so the projection was quite accurate. The drive was all freeway with maybe 5 miles of surface streets. I set the cruise at 68 mph in Eco and let the car do the driving. It was a nice day, mid 70s to 80, so good weather

for range. Needless to say, I am mightily impressed. I was OK with the 206 mile EPA rating when I bought the car in February, but 276 miles? I already loved the car, now I have found a whole new level of appreciation.

Off to a good start with warmer weather. Did like 80 miles on hwy. Started at 100%.

3.6 is pretty good. With the warmer weather I've been getting 4.2-4.6 (AWD Wind) like @jjcgolf72 has above. That's a HUGE variation from the 2.8 I was getting over winter lol.

Yes, but he has a Gt. That’s a huge difference.
Yep, I’m also trending towards 300, usually right around 140-150 at 50%. I’m very very pleased with my GT’s efficiency. My round trip efficiencies have been hovering at 3.7-3.8 since we are now in the 70s or at least we were.

What tires and wheels are you rolling on?

I often see 4 mi./ kilowatt hour or more in city driving so I’m sure that 300 miles of range is doable. I’m always amused at the reviewers and commenters saying things like “pathetic” and “dealbreaker” regarding the range. “Amazing performance but…” Sure, if you drive in GT mode all the time with a heavy foot the range will suffer. I don’t think that most owners drive that way.

The last months my indicated range has been equivalent to 350-400km (220-250mi). That's on 21" winter tires and without trying to be efficient. WLTP norm as we use in EU claims 424km, so that is within range, if not occasionally using GT-mode.

However the standard Michelins have much higher RR than my winter tires. Will switch soon for comparison.
3.6 kWh is amazing, I was doing 100 mile round trips for the last 3 days and could only get around 3.1 at best if I drove it really carefully and that's in a AWD version, tried Eco and Normal and found it did not make a massive difference to be honest and at times in Eco going up hill it felt like the car was in glue it was so sluggish.

When I drove it like I wanted to this would drop to 2.5 so getting 3.6 in a GT is amazing.

Well done. (y)
I wish the existing Kia tool set made it easier to get info out:

Average of my last 30 days (with one 130+ mile each way excursion to wales) plenty of GT mode action where possible. (Stock (UK) 21" Pilot Sport 4s tyres)

Just looked at mine and with a distance of 710 miles it says my average consumption is 3.10 mi/kWh.

So with your GT model your getting more then me in the AWD version. :mad:
I owned a RWD Gt-Line before owning my GT, and when I received the GT, I got kinda scared, the mi/kwh was really low (I use kwh/100km myself).

In the GT-line, normal 70mph driving, I'd get 17-18kwh/100km (3.5 mi/kwh), and when I received the GT, that same exact drive was around 27 (2.3 mi/kwh). I was more worried about the "costs involved" and not really the range as I don't really need 200 miles+. In the UK electricity is now really expensive if you don't get a good deal (over half a dollar per kwh at home).

My GT now done over 1000 miles, and it's finally getting warmer, and I'm getting those numbers back to GT-line level ! I guess it was really just a temperature issue (from 5° celsius to 20).

Done a 120 miles trip last weekend, averaged just under 20kwh/100km, was really impressed.

I'm wondering if there is something to do with "brand new cars", that use more energy ? Or just temperature.

Good to hear.
I think all of the EV6’s can exceed the EPA estimate in warm weather. Just got to get the right foot to be a bit lighter….:)

That kind of negates why I got the GT to begin with.
Now it is warming up in the UK I am seeing over 230 miles range on my GT and 3.3mi/kWh in the car. Does anyone understand the app????

Driven under exactly identical conditions, the GT line will get about 0.7 miles per KWH more with stock tires on both.—Me and another forum member have tested this quite well a GT line shadowing a GT. Something else is at work if your range difference is that bad.

All good stuff, but the AC is sucking the battery dry on these cars... we open the windows, there goes out drag coefficient. What to do, what to do?
