I don’t get it. Does he do all his tests on the fastest freeway in America? 2.9 is terrible. Also while it doesn’t have a heat pump, the RWD EV6 has the ability to condition the battery pack.

No, in Colorado our speed limits are 75 and most people are doing 80-85. His 10% challenge is done at 80mph. He also does 100%-0% range tests at 70mph.

80mph is the average speed of traffic on interstates in a lot of the US, especially between cities. 2.9mi/kWh is actually a little better than what I get at that speed, but I have the AWD. For me, I get 2.9 at about 77mph.
@Christopher
It’s easy to waste fuel in an ICE car at 80 mph since fueling takes 3 minutes. You pay for inefficiency on an EV road trip though since charging takes longer.
On a 400+ mile drive, there’s a breaking point at some speed where the increased drag from high speeds ends up making your total trip time longer than it would take cruising at a more efficient speed.
@Maria
I haven’t done any tests, but someone did those tests in 2023 for running the Cannonball in an Ioniq 5. They found that as long as you have working 350kV chargers, it’s faster to go as fast as you can. In their case, that was the car’s top speed of ~115mph. That probably doesn’t hold true for cars with significantly worse charging curves. You can find their posts with the data on the Ioniq5 forum.
@Imani
Sounds plausible, but only if you assume 100% charger availability, which is reasonable during the Cannonball run at 2AM. In the real world, during daylight road trips, I’ve never made it through the day without waiting for a charger.
My last trip, there was a power outage at Harris Ranch, and the EA fast chargers to the north and south had 1-2 hour waits in 105-degree weather (of course, the apps never tell you there’s a line). I would have been better off cruising through at 55 mph that day.
With those 3 EA stations swamped, there was a 150-mile gap in usable stations on that route.
@Maria
I’m not going to argue with someone that ran the numbers because I just have my gut feeling, but around here, EA chargers are easily 5 minutes off the highway, longer if you hit a traffic light or people heading to Walmart. Better at 2am, but you still can’t go 115 on a frontage road.
On another note, I can’t imagine how frustrating it must be with 2 minutes of ‘initiating charge’ messages during a Cannonball run. It’s bad enough for me when I’m just trying to get to the next state for a concert.
