All of your driving with your new car has been in the winter. Give it a full year. My 2023 MSLR has a measurably longer range than my 2020 MSLR.
I'm well aware of the seasonality influence. I'm also aware that always best to judge over longer periods. I've trended energy consumption not only on my prior Tesla by all my ICE vehicles over the past 40 years.
I do have full energy usage statistics on my prior MS90D from July 2016 until when I sold it beginning of Jan 2024. One of the things I've actually do with my data is slice is by calendar quarter, so I'm well aware that my average usage in winter, say Q1 is very different than in summer/fall, say Q3. However, even when I look at my current end Dec through mid-Mar data on my new 2023 MSLR, I'm not seeing any significant improvement over that prior 7 year Q1 average of my 2016 MS90D
When I look at the image which
@sorka posted, it's a 131 mile drive over 2:36 min, so an average trip speed of right at 50 mph. I agree at those type of speeds I can see ave energy consumption numbers in 235-250 Wh/mi range. However, my comments are around my typical long range interstate conditions, so sustained driving at 73-74 mph. That's where I'm not seeing any indications of improvement over my older MS90D, with the only real improvements in useable range being from the increased battery capacity, both overall size of battery and also a brand new battery versus my MS90D which was around about 8.5-9% range degradation from new.
I'm also aware my data at the moment might be negatively impacted by my car still being somewhat new. There's a reason that all vehicle emissions/fuel consumption testing isn't run until after cars go through an initial 4k mile break-in period. That's not just ICE engine related impacts, but also friction losses in other parts of the drivetrain such as gear sets, bearings, etc. I'm getting to the stage where I'd expect I should be largely past that, so curious about whether I'll see some improvement in a couple of trips I have planned around the end of this month.
Now if someone has specific data to share for the type of highway cruise conditions I'm referencing, I'd love to see that as a point of comparison.
