I wish he had gotten an e40. It would have been better for this model’s testing if he had 19s instead of 20s. He had a worst case scenario.

I wouldn’t be surprised based on what I’m seeing with my e40 and other owners’ comments, if the e40 gets close to 300 in his test.
I'm thinking the same thing. I believe the eDrive40 will get over the EPA estimate with 18 inch wheels. This is my main reason on buying the eDrive40.........RANGE.

Are tyres really sole reason for such a low overall range (220 miles declared)? Or is bmw powertrain just thirsty? Tesla is maybe less luxury car but they always have way better consumption. Sure when I tested eDrive40 it had similar consumption as model 3 LR but tesla is 440 hp awd with 2 motors. I have a hard time beliving that tesla is the only one with low consumption, everybody is just way off.

Sticky tires.

The is eDrive40 vs the M50 with the same 19" tires give a difference of about 15 miles +/-.
The eDrive40 at 280ish and the M50 at 270ish.

Waiting for my M50......

Could it be that Tesla also has very optimistic consumption on board computer? That actuall range is a little bit higher?

Not sure how accurate this video is but from my understandingg is that they actually messure used energy (but not really 100% acurate but idea is valid). So in this example Tesla Y reports 18,7kWh/100km but consumption was 28% higher so 24 kWh/100km. To be fair, BMW i4 is around 13% off with same method



But on the other hand I think that they didn't include recuperated energy.

I have an e40 msport with 19" wheels and 859 performance tires.

I got the car with 100% charge and less than 30 miles on the odometer. (Perhaps from people driving it in and out of the port instead of delivering it.)

Looking at the myBMW charging history I have added 153 kWh of charge and now have 1067 in the clock after three weeks of driving. The state of charge is 50%, so add 40 kWh to bringto the starting point.

That gives me 1037 miles per 193 kWh, 5.37 miles per kWh, and a total range of 430 miles from full charge to dead stop.

My last road trip was on Saturday, when I started at 100%, drove about 250 miles, then charged to 80% with 44 kWh.

Counting 16 kWh to get back to 100% I used 60 kWh to go 250 miles, 4.16 mile per kWh, or 333 miles total range.

I drove the whole day in eco pro mode and B drive regeneration. The drive included highway driving at 65 to 75 mph, winding mountain roads at 30-45 mph, and town driving.

Note that my control screen tells me an estimated range of 275 miles at 100% charged, while myBMW tells me I have 150 miles of range and 49% charge or 306 miles range.

I have yet to do a really controled test of 70 mph on a flat highway in various modes (That wouldn't be fun), but I can sense a difference between 60 and 70 mph.

I am enjoying the assisted driving (self-steering) with two caveats: it is slow to respond in sharper curves, so needs to be watched on minor highways with sharper curves, and is not safe on narrow country roads with uncertain lane striping; also when changing lanes it seems to switch off when I lock in the turn signal, so I must then grab the wheel - I should just tap the turn signal (use the three blink mode).

Thinking of range on a long trip, there is a trade-off between driving faster and recharging more often and going slower for more range. Considering that fast chargers are spaced at 75-100 miles along major highways, I would probably just target particular fast chargers every 200+ miles and recharge to 80% each time; that gives you three hours of easy driving (and listening to the good sound system) between stops.

George, interesting & great results. I suspect (not sure what) something is wrong with your first 430 mile range estimate. I’d like to believe it can be achieved (downhill?) but I’m really not sure how it’s normally possible to achieve that kind of range in an i4 with its 80+ battery pack. The 430 mile range estimate is into the long range Lucid category with a far bigger battery.

Your second result is in the same ballpark I’m seeing with my e40 and 19” non-performance tires and, like you, I’m primarily driving in Eco Pro.

Ken,

My 1000 mile average includes a lot of low speed driving, and the numbers are recorded by the car, so I can't think of an obvious error. The only guess was my adding 40 kWh at the end to bring it to the initial charge.

I will someday do a controled highway test starting and ending with a measured 80% charge.

decent range.

i've put in for the m50 with 19"All seasons... By the sounds of it I should beat that range...

Planning on 18" for winters...

I'm just charging my M50 to 100% in readiness for a long round trip. At the moment, the app is showing 96% charge and a range of 297 miles! Hilariously optimistic…. or is it? We shall see.

[EDIT] Ah, the app now reports 100% and 313 miles!

Also getting similar predictions to be fair on my M50 (19" 861s) - actually think may not be unrealistic too. Just had a 190 mile round trip, getting home with 24% battery left with predicted range of 75 miles (started at 90% battery). Most of the journey was motorway with speed set at 75 mph. It is definitely more than exceeding my expectations with range - with some fun, spirited driving too!!

The one aspect of coming from my i-Pace to the M50 was the worry I might only get a similar range (220 miles on 22"s) – or potentially even less, judging from some early press. Happily, that does not appear to be the case!

Yeah, I'll report back in a day or two.

So, just drove from Bath to Bristol, then to my mom's in the West Midlands, then back to Bath. Round trip of 216.7 miles according to the car (which tallies with Google maps). Battery level was at 100% before I set out (no preconditioning or anything) and I just got back. Total time in car, four hours, 25 minutes.

Now, it's been a lovely warm day, with little or no wind, I haven't hammered the car (bar a few little testers!) and a good 95% of the journey has been on motorways, set at 72mph in Eco Pro (that's probably 70mph as BMW overestimates speeds). Air con was on, at a comfortable 19 degrees. Unbelievably, the car is reporting I have 28% battery left with an estimated 87 miles of range.

That, ladies and gentleman, is a total range of nearly 304 miles. I am astonished. Perfect conditions, true, and I was trying to get a decent range, but that's way beyond what I expected.

I sort of feel around the 70mph mark is a sweet spot. I did a short stint at 75 and noticed the range dropping more quickly. Same thing if you have a little fun with both motors. (I'm sure if I was near the Autobahn and not in the nanny state UK I could rip through the battery in an hour, hour-and-half. But it would be lots of fun!)

The car itself behaved well. I used the ACC and lane keeping for a lot of the journey, so was gliding up and down the M5, with just my hand resting on the wheel.

However, the auto lane changing is really hit and miss; for a while I didn't even think my car had it. To make it work you need completely clear lanes, then it gently drifts over as you indicate. However it takes too long, and on several occasions it didn't read the solid white line along the hard shoulder, and I ended up bouncing along the rumble strip. It's a fun gadget, but I don't think I'll be using it much unless they patch it, make it quicker to operate and a bit smarter/more responsive.

However, all in all, I bloody love this thing. It's the fastest, most technologically advanced, quietest car I've ever owned. And with the range it appears to have, who needs an E40?

That sounds promising. The only problem is, 70 mph is a very inconvenient speed on the German autobahn. You either drive 55 mph behind a truck or 110 mph in the passing lane. Anything else is no fun because you're constantly being overtaken.
 
#31 ·
Yeah, sure. Today was a range test for me, under the sort of circumstances I could live with, just to see what it might do. Ordinarily, I'd be doing around 75-80mph there and back. Next time I'll see what range impact that has.

I'm on 19s. I do wonder how the E40 will compare. Yes it's a bit lighter (2125kg vs 2215kg), but then you have all the strain on a single motor to push the car along.

The M50's WLTP range is up to 318 miles, so I guess 300ish isn't that remarkable. Either way I'm very happy with that result, when I thought 250-260 would be its max range!

The ‘strain‘ of a single motor never hurt any ICE cars nor did it hurt the Tesla MS with a single motor. This is a total non-issue.

No one except BMW knows why the single motor i4 40 only has a top speed of 190 kmh. It could be a marketing decission, or it could be limitations (temperature) on the single motor ? or it could be something else ? Most EV's has had thermal issues, one example is Tesla model S that was not able to complete a single lap on Nurburgring in the first years.

Misha Charoudin was working as a rescue truck driver on Nurburgring at that time. A big part of his job was to rescue norwegian model S that only managed half a lap.
