Yes, the more I drive the car and track the more it becomes obvious the dash is truly a GOM, both the range estimate AND mi/kw reading. I have seen variations .3-1.2mi/kw calculated vs dash.

Have you found the dash to be optimistic, pessimistic, or all over the place? There are going to be inefficiencies in several places... The on-board charger probably has around a 5% loss. I assume that's not being accounted for. Energy will be lost in the round trip of regenerative braking to the battery then back to the wheels. I expect we're probably spending a little more on electricity than what the miles/kw readout would have us believe.

I just completed another round of testing of the EV6 GT(576HP) vs the Wind RWD(225HP) doing a range test on the highway. This was performed real world. We had 2 adults in each vehicle and put in 50lbs of luggage for normal work gear. No drafting or energy efficiency extras were performed other than being in Eco Mode. Both vehicles were driven normally with all creature comforts. The reason for using these two models is one is the highest rated range, the other is the lowest. Here are the details:

• Average temp was 70 degrees.
• Both vehicles were in Eco Mode.
• Both vehicles had Automatic Climate set to Level 2.
• Both vehicles had 2 adults in them, and 50lbs of luggage.
• Speed was set on cruise control to 61 mph.
• Both vehicles had android auto running, with music playing, and both vehicles have dash cams (minor power draw).
• EV6 GT(576 HP) Tires = Goodyear Eagle F1 stock (P255/40R21)
• EV6 Wind RWD Tires = Kumho Crugen stock (235/55/R19)
• Both battery packs are showing 100% SOH.
• EV6 GT has 11,500 miles on it.
• EV6 Wind RWD has 34,000 miles on it.
• This test was performed in North Texas. It is important to note, we are extremely flat here with only very minor rolling hills.

The results were:

EV6 GT(576 HP) = 3.0 miles per kWh for a range to turtle of 221.4 miles.
EV6 Wind RWD (225 HP) = 3.7 miles per kWh for a range to turtle 270.65 miles.

These ranges were ran using the usable battery pack until you hit turtle mode. The reason for 61 mph is to prevent the Cruise Control Auto Nav system from adjusting the speed.

If you didn't see before. The range test results were performed at 75 with a temp of 42 degrees (with all creature comforts on including heated seats, running android auto, music, and dash cameras).

EV6 GT(576) HP = 2.4 miles per kWh giving 180 mile range.
EV6 Wind RWD (225 HP) = 3.3 miles per kWh giving 248 mile range.

I think these tests are important because they are run with the creature comforts on, and my next test will be a 65 mph test of both vehicles 100 miles round trip.

Thank you for this great research. It is VERY helpful!

So far the dash has been optimistic. What would really help is to have two range estimates. One that is based on last two charges. Plus one that is based on last 5 or 10 miles of driving (if nothing changes). Or similar. I run software with an OBD-II which gives me the actual capacity in the vehicle and then you can simply calculate your range with the true mpkWh. I know some have also tried to implement this into the apps, like EV Watchdog does with its graph.

Gt has very different brakes, notably calipers that stick out quite a bit close to the hub. Primary clearance issue is the inner edge of the caliper. Wheels need a decent dish on backside to clear, regardless of wheel ET. View attachment 12302

So it’s not the diameter of the discs or the calliper placement, but the fact the wheel spokes barely clear.

One option is to purchase different wheels, the other is surely to upgrade to some willwood or Brembo 4 pots.

What was your tire air pressure?

What was your tire air pressure?

36 psi all around. 36 psi.

Under the 75 mph test( cruise control) at 42 degrees my AWD gets 2.8 m/ kWh or 208 miles ….pretty consistent with your numbers, a piece of advice……don’t get the GT(576) If your planning a lot of road trips.

For the next test.. you should swap the wheels and see if the 19 vs 21 makes a difference for the GT and the Wind.

If you can fit the 19s on the GT that is.

The 19 inch wheels will not clear the brakes on the EV6 GT. I will need to find some other source of wheels.

I have looked into other EVs like the Taycan and Model S Plaid that have similar horsepower. Both are running 19 inch fronts and 20 inch rears. I am torn between running 19 all around for the test or a mixed set.

Plaid has almost double the horsepower They do both use 255/45 sizes but do the Plaid wheels clear the GT calipers? Lots of support for aftermarket Model S wheels so good luck.

Be curious to see what a Wind or GT-Line AWD would do. Because I get 3.9-4.1 M/KWH in my Phoenix winter (similar weather) in my AWD GT-Line as a mix of City/Hwy. And, pretty close to 3.7 on just highway.

S is wrong bolt pattern. The 3 has same bolt pattern, like always the big issue is the dish on back of wheels and if the spokes will clear the inner edge of the caliper on the GT. I have 20" aftermarket wheels designed for a Model 3 on my GT but had to use 3mm spacers up front to clear brakes.

can I ask what regen mode was used? (unless ECO fixes it?)

I did not know that. Good to know.

Cruise Control fixes regen mode, but also this was on highway so regen isn't really happening.

 

[runtble]

In a GT with 20" Drag wheels and PSAS4's, I averaged 2.3mi/kW going SLC > Boise and Boise > SLC in temps ranging from 39 to 24. Most of the trip was with cruise control set to 75 and cabin set to 70*

Pretty much aligns with what I see in west WA with similar settings on 20" liquid shift wheels with AS05 and DWS06+ tires.

The reason I mentioned it - and forgive me if it's not relevant, I don't have my EV6 yet - is that I read here that level 3 regen mode forces both motors to be engaged, such that if you DID brake, you get max regen. And this, obviously, gives an efficiency hit. Whereas apparently in the lower regen modes, the car can drive RWD only. So, although no regen is actually in play, supposedly there is an efficiency difference.

What I'm not clear on, is whether ECO mode forces a lower regen level, thus keeps the car RWD at all times.

So, i suppose what i'm really asking is: are you numbers for AWD behaviour or RWD-only behaviour

 

[dc30307]

I-pedal forces both motors to stay engaged, not level 3. ECO forces the front motor to disengage above about 15-20mph (except i-pedal overrides this). But max regen is available in all modes, with the left paddle, or brake pedal. But as DocBeech said, regen levels aren't relevant while cruise control is active. Cruise uses regen as needed.

Both Eco Mode and Normal mode will keep it in RWD on the highway up to 80mph as long as the front wheels are not needed for say climbing a hill etc.
