What OBD reader and software are you using?

Are the 65mph numbers considered medium or high speed?

 

Using a Vgate Vlinker and ABRP has a live connection option that track it along the route.

I have CarScanner as well, but I’m calibrating it with ABRP right now so future uses will give me more accurate planning.

Including some additional datapoint, each of these are continuous between stops or per leg:

233mi / 68mph Avg / 2.91mpkWh
52mi / 46mph avg / 4.05mpkWh
179mi / 66mph avg / 2.65mpkWh
57mi / 35mph avg / 3.12mpkWh
207mi/ 65mph avg / 3.16mpkWh
176mi/ 68mph avg / 2.68mpkWh
105mi / 76 mph avg / 2.04mpkWh

I have elevation, speed, and power data as well. It’s a bit much to post it all but I can provide specific leg requests.

Here’s a sample of the 4.05mi/kWh leg, you can see there was a good amount of stop and go and I was generally going down in elevation, which allowed plenty of regen

 

I have elevation, speed, and power data as well.

Can you get wind speed and direction? Looking at your data, there's a lot of scatter. I see the same in mine, and find wind is the likely culprit.

My EV6 database is mostly loop trips, where wind averages out. Depending on wind direction, my efficiency over 4 legs can be within 0.1 m/kWh, or more than 10x that. Route and speed are identical. Temperature in GREEN to show seasonal effect.

 

We are currently choosing between a Rivian R1S Max and an EV9 GT. I really like the Rivian’s range up to 410 miles. If the Kia had more than 270, I’d grab it in an instant.

How does the Rivian real world range hold up?

 

The Rivians range was excellent, with a caveat.

The Quad motor disconnects the rear motors - similar to how Kia’s eco mode disconnects the front. If you are considering a dual motor, those operate a little differently and doesn’t fully disconnect the other motor. They also changed the battery chemistry and I wouldn’t be able to fully speak to those (some folks reported not getting any actual range increase over the originals, but I can’t confirm nor deny it myself)

But generally, the range has been conservative on my 2022. I routinely did 280-320 miles in mine on 22s and it was EPA rated for 314 on 20s.

A couple of important factors to consider:

• The Rivians frunk is far more usable than the Kia.
• The ride in the Kia is better than the Rivian, despite not having air suspension.
• The Kia has less wind noise at speed (GT-Line) vs early build R1T, so take it with a grain of salt.
• The capacitive touch wheel is better in the Kia
• The Rivian is built with significantly better materials, touch and feel.
• Rivian has some of the best, if not the best ventilated seats I’ve ever used. It’s barely noticeable in any other make, including the Kia.
• Efficiency, the Kia is roughly 10% better than the Rivian at 65mph, almost 20% better at 85mph+.

Last thing since you mentioned range, how you use the car is more important than the range.

The Rivian charges like a Tesla, it’s peaky. So if you’re doing road trips where you’re using multiple DC charge sessions, you’ll only grab a charge from 10-70% max, and likely best if you only grab it until 55-60%. So after the first leg, you’re only able to use half your battery. For my car, that’s only 160mi of range on leg 2 despite doing 300 on leg 1.

The Kia charges really fast and holds it pretty steady up to 80%. Leaving 70% usable after the first leg (189mi). So by the end of Leg 2 both cars are about dead even. If you do a 3rd leg, the Kia starts to win with less overhead and more range.

If you don’t do a lot of road tripping though, none of that will matter. Both cars are capable of driving 8 hours+ straight at 65mph on 1 charging stop (starting full), and not many people do that.

 

We've had a Land AWD for a week. I've done a 70 mph road trip from near Portland Maine to Bangor and back and concluded that day that the EV9 is a road tripping boss. Efficiency was pretty good, doing 3.1 m/kWh north and 2.9 returning against a stiff head wind the whole return trip. I left home with a full charge and optimistic GOM reading of 330 mile range. It turned out to be not far off, I figured that potential range to zero SOC that day would have been 310 miles. As Björn has often noted, the EGMP cars batteries don't discharge in a linear fashion. Discharge rate quickens a bit toward the bottom. The car is very impressive though, I traded an EV6 for the Land and have been happy that I made that decision.

 

What trade in value did you get for you EV6?

 

Dear Mr. @billcarter
In reference to the linear fashion of HV DC packs, as the state of charge diminishes during driving, the total pack voltage correspondingly decreases. Consequently, to maintain the same power output, a higher current is required compared to when the pack is fully charged and the voltage is significantly higher.
This is the reason for Bjorn's confusion. The BMS is actually using the remaining Ah to address the remaining SOC with other inputs on top of them.
If you require more accurate information on energy remaining (ignoring SOC altogether), I recommend using the Carscanner Pro app.
And the EV9 is not a true 800V architecture, and at a low SOC level, this is more evident because the SOC percentage is actually falling down more quickly (but it is accurate information, even if it makes the owner question the sudden changes in how SOC is related to the miles traveled).

 

245 mile trip. Started at 100%. All flat land. Driving 70 to 75 the entire time. A/C on eco and on 73 and turned on the entire trip on fronts only. Eco mode drive. No radio. Level 3 regen (barely used any brakes).

Ended with 7% battery.

This is Land model.

 

Took our first EV9 Land mini road trip to Savannah (to drop off our Model Y lease) last Friday and came away super impressed.

253 miles
100% - 14% SOC on Eco mode
5+ hours, avg speed 51mph
Midday 90-95 temps, 5-10mph winds
Minimal elevation changes

I only once made that trip with that Model Y LR without a quick charge at halfway point and I think I got it back at 4-5% SOC (and that car supposedly had a better EPA estimate).

And what was such a surprise—and relief—is it pretty much performed as advertised without a huge delta between estimated range remaining on return trip and what we arrived with (which was my big complaint about the MY and always underperforming—by a lot).

Other than the awful DC+ charging network in our area, I would have ZERO problems taking this out on road trips. It was fantastic. Quiet cabin, smooth ride, super comfortable. Just a splendid experience.
