I like being on forums with other people who can do math!

ECO Vs Comfort Mode

So I tried a test today to see what the usage was in each mode on the same stretch of road. Now the stretch I used was only about 8 miles, but I saw a considerable difference between the two with the Eco mode using almost 10 KwH less than the comfort mode. That is huge. Anyone else try this yet?

Speaking of math ....

If you guys do those sorts of experiments don't get all worked up about a difference when you've only done it once, alright???!!!

Do it three times at least, ok? I think some die-hards on this forum will even be convinced to do 10 replicates.

Totally true!! However, same day, same weather/wind conditions is also still valuable/helpful! Anything that gives you repeat results and minimizes the variables.

Best range test is always a loop on an uncrowded freeway with the speed control set. You use map mileage and if possible measure the amount of juice going to it the car at recharging with a smart EVSE.

2 strange items for today's driving experience. I drove about 31 miles around town (all City driving) in Dynamic mode for some spirited driving fun...but this time, I started out after a full charge to 100% last night at only 216 mi. (was typically charging to 230-245 mi. the last few days). So that was weird thing #1. Now, after today's driving around, I'm back at home with 183 mi. left at an 89% charge, BUT weird thing #2 is that it shows I averaged much lower battery usage than ever before...only 34-35 kWh/100mi. Hmmm...any thoughts?

Normal. Many other EVs the range displayed is known as the GOM (guess-o-meter) for a reason. I would not expect much consistency.

Okay but what about the battery efficiency down to 34-35 kWh/100 mi.? I was getting like 38-39 kWh/100 mi. City and 44 kWh/100mi. for highway driving. Interesting that my battery usage/efficiency also changed quite a bit...not sure what to make of that unless it's just a factor of the decreased total max range at first start?

Amazing how aware we become of our energy usage and the related fluctuations in an electric vehicle.
I still call normal. Just drive.

I mean unless you make the exact same drive every day in the same wind and temperature and traffic and a hundred other conditions the usage is just not going to be the same.
Some days will surprise to upside and others to the down. in a few months you will find a normal baseline and better relate to the fluctuating data.

Wow! I got put in the doghouse today. It was pouring rain, and I climbed 2400', 50-57F outside with the heater on, normal mode, headlights, stereo, wipers, gentle driving, no faster than 65 mph, and my range would be about 201 miles according to Guess-o-Meter, but when I do the math for 67 miles using 28% of the charge, that says 239 miles.
I wonder which one is right?
There were several accidents, including a black import sedan on it's roof in the #1 lane of the 241 Toll Road. Many cars when off the road into the median, a couple spun backwards. Few collisions.

In California, we do not know how to drive in the rain. They think hydroplaning is an Extreme Sport on ESPN, and water improves your braking distance.
