I’d like to learn a bit more about the AWD EV6’s range when in Eco mode. Is it comparable to the range of the RWD model?

 

[Coddy]

Don’t really understand your question.

But a RWD model will go further than an AWD model, if both are in the same mode (Eco, Normal, Sport).
Also depends on size of the wheels, 19“ will give slightly better range than 20”.

I’d like to learn a bit more about Kia EV6’s range when in Eco mode. Is it comparable to the range of the all-wheel-drive model?

Here is the official UK range specs, obviously these are pure fiction but they give you an idea of the differences between RWD/AWD and 19"/20" wheel sizes.

I think what @Ken Chalk is asking is whether someone had ever done a head-to-head test between an RWD and AWD of the same trim level, with both run in Eco mode (i.e. front engine disengaged for the AWD) and confirm whether real-world ranges still differ by so much.

As there is a weight difference, they would naturally have different ranges. By how much? Dunno

Nailed it.

 

[Cnsheets]

Gross Weight (lbs.) (RWD)	--	5,335 lbs.
Gross Weight (lbs.) (AWD)	--	5,556 lbs.

 

[EV61ED4ME]

Gross Weight (lbs.) (RWD)	--	5,335 lbs.
Gross Weight (lbs.) (AWD)	--	5,556 lbs.

That's only a 3% increase in weight. But according to US range numbers, range is 13% less for AWD vs RWD. I'm guessing the evaluation was not done in pure Eco mode.

Also if the range in city is 426 and combined is 313 (for 20" tire), not sure what is the mix in the combined figure, does that mean the highway range is 200-ish under ideal condition? And if cold weather penalty is 40%, does this mean highway in Canadian winter is 120miles (190km!)?

Hope I'm wrong!

Guess I won't let my dog in the car (~40 lbs)

At -30°C? Probably. Except the first part of the journey when you leave the house since the battery will be warm from charging.

I plot a route from Edmonton to Calgary on ABRP for fun with temps at -25°C and 23°C assuming leaving Edmonton with 100% SOC. Both require a stop at Olds to arrive in Calgary with 10% The difference is that in the winter, the suggested charge time is 16 mins whilst in the summer, it’s 7 mins. You would arrive at Olds with 18% charge in the winter vs. 35% charge in the summer.

Even with the front motor disengaged, the front drivetrain (differential, half-sfafts) are still rotating any time the car is moving, so there is some friction from that, plus the extra weight.

Err yes - the WLTP combined figure is made up of 52% urban and 48% extra-urban (30 min lab test under strict conditions etc). So yep the open road range is not the best

 

[Coddy]

I expect the WLTP is done on a rolling road as well, with no wind resistance, no gradient changes.
Same as how ICE cars are tested, to get big mpg figures.

Oh, and how cheat mode is enabled by all the manufacturers, not just VW.

I think that's right - lab, rolling road, clearly defined parameters for speed etc - recall reading somewhere the temperature was 23° but can't find that reference now. Will try and find it and revert

 

[Coddy]

Yes, all very static. All run the same parameters, but the main one is no wind resistance and no gradient changes.

The reason VW got caught, and how others were doing it.
When the car was on the rollers, obviously it didn’t know it was on rollers.
But, the clever bit was after the car had driven a certain short distance and it had felt there was no steering input, it figured out quickly that it was on a set of rollers / test bed, and did the alterations to the fuel.
All the sensors in cars are now constantly thousands of times a second monitoring, throttle position sensor, engine rpm, steering box movement and difference in wheel speeds on the 4 corners, for the Traction Control, ABS.
On the rollers, under the test, everything stayed the same, which is not possible on the road with human inputs and environmental change.

Hey, in thanks for me finding this, can I kindly request you edit the title of this thread? It's kinda gobbledy-gooked and mucks with my brain.

Article that finds very little range difference between RWD and AWD:

Så mye rekkevidde gikk tapt i vinterkulda

Alle de 31 modellene i den store rekkeviddetesten hadde et avvik fra oppgitt rekkevidde på mer enn 10 prosent. Mange av de nye populære familiebilene rullet mellom 10 og 15 prosent kortere enn lovet i vinterkulda. Luksusmodellen Mercedes-Benz EQS knivet hjul mot hjul med folkefavoritten Tesla...

Apologies if I'm being dense, but I couldn't see from the article mention of the Eco mode in an AWD and how it affects range. Can anyone point me in the right direction?

In eco mode the front motor is actually disconnected unless it's required (stability control, acceleration). So in highway conditions, the main difference between an AWD and RWD (with same wheels/tires) will be a hundred-ish kg of weight.

Thanks for that Robby. How do folks get so knowledgeable about the mechanical details? I am impressed.

I think with only $2000 price difference for AWD, I will probably go that route.
