100% Charge Low Miles
Featured on BIMMERPOST.com M50. 19 inch wheels. New vehicle. It should charge to 271 miles. There’s a brand new M 50 at the dealer right now, 100% charged, but reads 240 miles. 5 miles on the vehicle. It’s inside and plugged in. Is there anything to be concerned about? |

The "271" miles is the EPA estimation, not what it "should" be. What your EV (any EV) will show as range at any time are the miles estimated at that moment in time and conditions (battery charge, speed, braking, city or highway driving, recuperation, tires, weather, load, and so on).
Range can go +/- 75 miles depending mostly on your driving conditions. |

Its cold. Im barely at 220 at 100 percent. I drive mostly in eco pro to and from work. Range will increase as summer comes.

Ran mine down to 2% today so I could use a more convenient charger . Holy s the nanny warnings are out of control I'm literally navigating to a charger using the Idrive find a charger feature and the car keeps popping up messages and audio warnings asking me to navigate to a charger..
One of the annoying messages said something about a hot battery and how stopping for a long period of time would cool the battery and create a loss of range which I never really thought about despite the physics making great sense, cold car plugged in = less range so when you leave your garage in the morning expect the range to either hold at a certain level for a while or increase a bit as you get going. |

I don’t regularly charge to 100% but have seen between 155-195 miles at 80%. It isn’t just temperature but recent usage that affects the range estimate. 5 miles isn’t much to base this on…

I have never achieved 200 miles yet. Usually about 180 miles. But I am averaging 2.2 mi/kwh over 400 miles, so makes sense. In the same scenario, my 2019 i3s averaged 3.4 mi/kWh. So the i4 is definitely more thirsty. But it also weighs 2000lbs more, so understandable. Where the i4 does better is on a hey trip, where even going 75mph, I can get 3mi/kWh. Thats close to my i3 at that speed. I do a lot of full throttle acceleration around town though.

Over 1300+ miles so far my M50 has averaged 3.2-3.3 mi/kwh with the 19" wheels. Assuming the 84kwh in the battery I've been reading online, that's about 275 miles full to empty. And we're still in winter. That's fine with me. Around town I generally drive in B mode and don't go too crazy with the acceleration.

I finally charged to 100% the other day too. For the first few 100 miles I was showing 170 miles at 80%. Granted that did involve being an idiot and showing my friends what the car can do after they said why electric.
I have a eDrive40 with 18s and drove 231 miles over a few days SOC showed 26% and range shows 66 miles left. Car has 1770 miles and the trip was a mix of city and highway. For the first 65 miles I had the ac off since it was chilly last weekend. Needless to say I didn't drive enthusiastically, I wanted see what range was achievable. The average showed 3.9 to 4.0. Based on my math if I drove to 0% SOC the car would have hit 297 miles. 4 miles off of what is advertised is acceptable for me. Whatever second thoughts I had about the car being an EV I dropped off at the the gas station down the street before I pulled into my garage to charge up. |

Nice to hear this! We have the same car on order as you have, just because we wanted max efficiency and range.
I watched a test a while back that showed that the diff between 18" and 19" wheels on a skidpad etc is virtually nothing. Depends much more on the rubber you mount. Not that our car will ever get driven that hard... And with 18's you get a bit more comfort and daily protection against potholes and such.

In addition to range (wow I almost typed mpg) I preferred the 18s for 2 other reasons. I love the dark color vs two tone. We have a highlander xse and I am not fan of the those rims. Wifey likes them so they stay (I pick my battles). More importantly is being able to rotate the tires. I had a 2007 328i coupe (e92) changing tires got pricey. My cousin who bought the latest 3 series m sport was complaining about the staggered setup. Her back tires became thin before the half way point of her lease.

It's a tough decision when ordering single or dual motors, I went with the single for a few reasons; I don't drive on ice or salted roads, I have Jeep for that. Secondly, my choice was for range or extra speed, so I took the range because I always need that and seldom need the acceleration of a 2 motor EV.. Mike |

ASK THEM!!! And tell us what they say!
Only if it slowed down that much at 90-100% SOC would that make sense to me... Or if their charger is one of those new ones that uses a battery to buffer energy from the grid and then pushes that to the car... Those can only charge so much in a time frame before needing to be replenished.

Car just arrived late last night and I jumped on the purchase since someone backed out. I’m hoping it’s their charger that’s the issue. And as we all know, I can’t leave with it until 100%

What was the percentage when you started charging and what percent or range do you need to get home. I know your going bonkers to get in the seat. This is why I'll always call a dealer 2-3 times prior to when I arrive to look at a car to make sure its fully charged.
Let us know how you like the car! Mike |

The customer that ordered the car seemed like he did not want it and I was going to buy if they did not. I was trying to figure out what was wrong with the car and that popped out. He bought the car. So I'll wait for the one I ordered.
It makes sense that the range would be dependent on several factors. Even with my 235, the range can show really low, but I know I have lots if I drive differently. Just more variables highlighted on an EV. |

It's important to note - If a car shows 200 miles remaining range, you can easily get 220-240 miles or only 150-170 miles. BMW likes to show conservative range. I can confirm this owning three BMW I3's.
As an example - the other day we left the house in 50 degree weather and our I4 /40 (single) showed 158 miles remaining, we drove 12 miles to town and when we stopped for breakfast, our the range went up to 169 miles. This is an increase of around 20 miles when from the estimated range shown when we departed and drove 12 miles. My BMW I3/120 does this same thing. This increase in range was due to a number of reasons, such as the manner we conditioned the car (seats only) slow speed (45 mph), plus the warming of the battery from use. While I dislike seeing 249 mile on my I4-40 after a charge when it should read 280-300, I knows its only a estimate of what the processor thinks it learned when it calculates temperatures, conditioning, driving habits and speeds accumulated from past charge cycles. The I-4 40 will travel 280-300+ miles on a charge if you respect its limitations and consumption. Regards - Mike |

20" tires have less range
I'm getting on average 200 miles per charge on my M50. I think its because of the 20" tires. BMW build website even shows 44 miles less with bigger rims.

I think I've figured out a big reason why we see "low" numbers on the distance left display: The distance left display is showing distance left until the battery reaches 20%!
When I recharge my i4 M50 up to the recommended 80% it always shows me 160 miles. So how did it come up with that number? The BMW App says that I'm averaging 31.2kWh/100mi. We know the battery is 84kWh. So 84/0.312 is 270 miles. That's my full battery range. 60% of 270mi is 162 mi. That matches up. When I charge to 80% the distance display is taking the 20% off the top and 20% off the bottom. They don't recommend using the battery under 20% charge. |

Hello - Regretfully the battery is far less than 84kw. The manufacture incorporates a buffer zone so the owner can never fully charge nor fully discharge the battery. While few manufactures disclose their design and readings, it's my guess there is roughly 70kw usable. In addition the BCM will will automatically deduct mileage depending on temperature and your past driving habits.
Another problem is there is no way for the BCM to show a more accurate range unless you fully charge. When charging as the voltage rises to the set level and the charger stops, it updates the SOC circuitry to update the batteries capacity, otherwise it has no idea of the batteries true capacity. You should fully charge at least once a week if you expect the range to be accurate. Regards - Mike |
