... so my point of reference is a 2018 Model 3 LR-AWD. I've driven that for 80,000 miles. And, now, after 2 months of owning a 2025 Cybertruck dual-motor, besides being quieter with more soft surfaces inside, the most surprising thing has been the overall energy efficiency.
I was expecting it to be 50% less efficient. The battery is >50% larger, 123kWh vs 79kWh. The rated efficiency 377Wh/mi is also >50% higher. The weight is >50% more. In some ways, it was nice, because the math would be easy. Driving to my usual places would take about the same amount of SOC, since the EPA-rated range was similar, 310mi vs 324mi. Instead of making 13mins stops to charge, I'd be making 20mins stops. That sort of thing. Easy math.
Instead, I've found the CT to be more efficient than expected. Here's an example. I've driven the CT on my normal daily commute for 6 days. The weather is pretty optimal, barely requiring any heat or cooling, In my Model 3, I'd expect an efficiency of 225Wh/mi. For the week, I got 304Wh/mi in my CT. That's only 35% less efficient. Yes, I'm driving on country backroads, going about 45-55mph. But, that shouldn't matter, as I'm comparing it to my Model 3 on the same roads, driving the same speeds, facing the same temps.
Here's another example, of me driving home from skiing. In my CT, I drove ~73mi, and used about 18.4% SOC, just for the driving.
And, in my Model 3, I drove a little further 75mi, and used 25% SOC. Ignore the heat used, and only look at the driving SOC usage.
The 3 predicts 22% SOC, while the CT predicts 20% SOC used. I actually used 18.4% for the CT and the 3 used 25%. Not what I was expecting. The time of driving and thus the speed were almost identical. I do this drive 25-50x a season, so the speed is almost always the same.
Maybe, at moderate 45-60mph speeds, the CT is more efficient than expected? Anyhow, I've been pleasantly surprised.
Edit: June 13th, so, I drove my Model 3 for a week. And, the last 100mi the efficiency with no climate usage was ~230Wh/mi. Not far off what I predicted at the start of this post, of 225Wh/mi.
but only 25% better than what my truck is showing:
Just so surprised by the efficiency.
