Tesla states 90%, not 85%.

Also, there is no "forcing". It's simply a slider that lets you set charge between 50 and 100%. It's not like there's a warning that you have to override or anything like that.

I skipped through the video bc my main thing I wanted to see was the charging speed and the range he was getting.

also on his spreadsheet he stated the tesla M3P had 18" wheel dont those come with 19" wheel? I could be wrong but I know when it comes to range every little detail adds to the overall range etc..

I think almost all EV makers advice you to not charge past 80 or 90% for daily use. But when you do the occasional road trip, charging to 100% is perfectly fine and shouldn't do much harm. What's generally considered more harmful for the batteries is doing a lot of fast charging. So doing your daily or weekly charge-up at a supercharger is probably not a good idea.

When I said forcing I meant you need to go into the settings and manually adjust the slider to go past the 85% range. It doesn't default to 100%, and you are correct There is little marks on a scale that show DD range and Trip range (recommended) that you adjust. . Tesla actually leases a building from us and I asked the guys over there this yesterday, they stated 80-85%. On the car setting chart in the charging screen it says 80-85% as well from what I saw. Thats where I got that figure from. Either way I wanted to know if the BMW's tests for range have been at 100% or less charge as that would make a difference to me. Also I wanted to know what BMW's stance was on the recommended charge % which I need to read into on my end as well.

The car gives you 50%-90% for daily, and then 90%-100% for trips. I have it set to 90% for a majority of my driving. Then 100% when I head to visit family 400 miles away. You can set it to anything in between 50 and 100, but there is no specific recommendation other than dont charge above 90% unless you actually need it.

awesome, thanks for the feedback! Now we just need to get info on the BMW set up. I need to research it more

Same. Hoping to get one to be in addition to my Model 3.

Its fine for most people. You can pick up like 100 miles of range in about 12 minutes of charging. I took my 117 mi range 2017 i3 on 850 mile weekend roundtrips from LA to SF, and to Vegas just using the quick chargers and it was no big deal. Just time the charging with your breaks and snacks. This car would be even easier with the longer range and faster charging. 12000 miles per year = 33mi/day average. Most people dont need to go a few hundred miles a day on a regular basis.

As someone that is on my third EV and my M50 will be the forth and a Fisker will be the fifth.

The first was a Fiat 500e and it was definitely an in town car, although my daughter would commute about 90 miles a day. She would just park in a garage with an EV station.

The second was a Chevy Bolt along with the third. No range anxiety and range about the same as the M50. It has been on multiple 200 mile trips. Not even an issue.

As long as I can get from my house to Laguna Seca and Sears Point raceways, I'm good.

I had my E90 for eleven years and never went further than the racetracks.

I usually take the X5 on road trips.

With DC charging and stations available here in California. I might drive it to San Diego in the fall.

this guy here did a test drive on 18" 245 cross section studded snow tires:

https://www.******.com/threads/test-...44/#post-19226

264 miles of range

"my 2 cents for consumption from a test drive today.
I had a m50 with 245/45r18 studded Continental tyres for an hour.
Drove 54 km, ~15 km with 110 km/h, ~22 km with 80-90 km/h, and the rest was below 60 km/h in suburban traffic.
Consumption (according to the screen in car) was 18.9 kWh / 100 km
I did not try to be economical at all. Instead did 4 or 5 accelerations in 0-60 km/h or 80-110 km/h "ish" speeds.
The weather was -2,5 at beginning and +0,5 celcius at the end.

Edit: the image was taken when stopped.
During test drive, AC was ON and set to 20/19 degrees.

Test drive car indicated 89% charge and 388 km range in the beginning.
About 1 km before finish, it said 77% and 340 km range.

I must say I was very positively surprised by the number."

264 miles in combined in winter test environment. Add like 15-20% back in warmer months and more slick tires for summer driving vs. studded tires (less rolling resistance), 310 - 330 miles

thanks for posting this! interesting for sure

I think his temperature readings is in Celsius not Fahrenheit.

So are mine To be fair you get lower mpg in an ICE car in really cold temps for sure.

1) those who get the data and can interpret what it will mean on multiple climate.

2) those who see numbers and don't understand literally anything but make comments just because

That is a very definitive statement 😊

I live in Southern California, I commute to LA and San Diego, I can tell you, the i4 range is definitely not just for City only. Cheers !

Who here is sticking with the 19” alloys for the better range or going with the 20” because looks are more important than range?

19's for range.

With 19's there is a decent chance of 250+ summer highway miles without needing 'away from home' charging. This should cover most of our usage. Even in winter 10 minutes on a DC charger should top up enough.

We have a regular 240 mile round trip to visit family… Average speed 50mph+. My 340i regularly exceeds its WLTP mpg. Though, I do not expect the M50 to be this side. Strangely, the WLTP test for EV's of any size favours urban driving more than the equivalent test for ICE vehicles…

[spool twice]

City/Urban driving would always favor range on BEV's for sure. They are more simple: kWh needed - - -> kWh drained + small losses due to heat/friction.

Sorry, I wasn't clear.

I read the EV WLTP cycle is different to the ICE WLTP cycle. They throw in extra urban cycles for the EV's. Playing to their strengths…

As a rural owner, the EPA numbers seem much more realistic in relation to my test drives.
