Hello,
Anyone here has experience driving from LA to San Diego with a M3 Standard Range Plus (SR+)? What was your experience? Was the actual range enough for the long commute? Should I charge to 100% before I head out or refrain from using AP and heater/air conditioning?
I recently got my SR+, but I am wondering if it is enough for my monthly commute to SD.
Thanks,
There was a video of a user posted here who got about 250Wh/mi traveling at 78mph nearly the whole way in an SR+ with minimal traffic.
This was at 6000 feet (lower aero loss), but it was no traffic, so at those same typical freeway speeds on the LA to San Diego drive I think 260Wh/mi is a reasonable guess, since perhaps those factors roughly cancel.
I don’t have an SR, so this is a guess based on video evidence.
Note this consumption will come down a LOT at lower speeds. At 70mph you’ll be about 225Wh/mi and 60mph you might be below 200Wh/mi. (The ~180Wh/mi @78mph aero losses scale with the square of speed.)
But anyway, prevailing freeway speeds, not in rush hour, not drafting much, 260Wh/mi is a reasonable guess.
This will give you 215Wh/rmi /(260Wh/mi) *240 rmi = 198 miles of range. Might even get 205 miles.
This is all in good weather, no heat, etc.
So definitely for a smooth sailing drive at the prevailing speeds, don’t expect more than 200 miles.
Note that the Superchargers that are on route can be busy, so would be relatively slow; personally I wouldn’t want to use any San Diego Supercharger. It’s a huge waste of time; something you really want to use for road trips only - unless you are planning to stop anyway. If you are stopping, you would not have to stop for long assuming the stop goes smoothly - here is the issue with that, though...
Here is the current status in San Diego, and it is not rush hour yet, so you will almost certainly be limited to 72kW (even for the 150kW chargers), and sometimes you will have to wait:
If you can reliably make use of destination charging in San Diego, it would not be a problem. Far preferable to a Supercharger, if it is extremely convenient.
Basically it depends on your exact situation, but destination charging options are likely to increase over time. The Supercharging options likely will improve with time as well, of course. But the increase in stations has to keep pace with EV adoption!
