Hybrid won't engage the engine unless the battery level drops enough or you request more acceleration than it can provide via the EV motor or your speed gets high enough (similar to above). So, in stop and go in the city, you may be running entirely on electricity and never engage the ICE.

You'll see a significant difference in the winter with the heating requirements versus summer where the a/c is more efficient than heating and how long you sit not moving at all.

With the US enabled capacity, the EPA says 31-miles, and that's probably good. More in the spring/fall where not as much heating/cooling is called for, and maybe less in the winter, while summer may be about that.

Everyone's driving routine is different and their gas mileage on an ICE will differ, too. Late braking, have to be the first across the intersection, unable to maintain a steady pace, all will cause less efficiency.

I want to replace my 40i with a 45e but can't figure out exactly how the 45e works. We have a Toyota hybrid which is not a plug-in hybrid but still gives me an idea of the process. In the Toyota you can use EV mode only or you can have mixed power where the battery helps the ICE but not only on hard acceleration, even in moderate acceleration. Is it the same process with BMW? If I drive in hybrid mode to use both engines simultaneously instead of jumping from the ICE to the battery and vice-versa? I drive about 50k kms a year and a small percentage is city driving. Mostly A roads and highways. Will it be possible to average 5 liters per 100 kilometers if I make a 600-kilometer business trip in one day, 300 kilometers each way, as I did last week? I got 10.8 L/100km in the 40i.

[biterror]

My average consumption is 4.8 l/100 km after over 27000 km. On long trips (1000 km per charge), consumption has been 7.6 ... 8.6 l/100 km depending on weather, speed, temperature etc. I don't think you could get down to 5 l/100 km on a 600 km trip with the 45e.

[nZtiZia]

pr0gi it's been shown and reported the 45e is more fuel efficient than the 40i because of the electric machine assisting the ICE, but it won't be significant over those long distances you travel

I think I can help, being in the same country and all
Short answer - no.
For me on the Sofia - Burgas highway (155km/h speed most of the time) I usually get 10.5 L/100km with empty battery.
If I start with a full battery it will be 9 L/100km.
If it's a slower road with be better, but not by much considering 600km is a lot.
Another example: Sofia - Pleven - Sofia, 10km/h above speed limit, 6L/100km with full battery, but that's only 340km total.

About 45-55 MPGs.

Depending on how I drive, the range on the next full charge fluctuates. Currently it's 46. Pacific northwest. In my last drive, I got a 5/5 on the driving style monitor in the car and after today's charge, I see 45 - the most I have seen.

Just curious - so you are driving in hybrid+? Are you observing more range from true coasting versus the regen braking?

[jad03060]

Regen starts when the motor is not pulling. Maintaining a steady speed, it's always pulling on the flat, but when you go downhill, you'll get some regen, and when you go uphill, if the engine is running, you'll get some boost from the EV motor. Regen increases as you release the pedal, so to 'coast', you'd not release it fully like you would on an ICE when in EV mode. Even when the computer says you can't drive any distance in EV mode, there's enough to help boost things along unless you were climbing up a long grade into the mountains. The only time it tries to stay in EV mode as long as possible is if you select EV mode, then, it will go faster before it turns the ICE on. In all other modes, the computer is making the decision what mode is more efficient, which can be a combination of one, the other or both motors except in sport mode, where it prioritizes performance versus efficiency and basically keeps the engine on.

My default is adaptive mode (done by coding it). Most of the time, around town, it stays in EV mode, but if it knows there's a hill ahead or a high-speed highway, it will turn the engine on to help make the transition smoother. Personally, I don't always hear when the engine turns on. The starter motor only operates from standstill, otherwise, it uses the EV motor, engages some clutches, and 'jump starts' the thing.

The engine is slightly detuned, the transmission is geared longer (lower RPM at speed) because it has the instant additional torque of the EV motor available to help it along.

I drive in the hybrid eco pro mode. If you have navigation enabled the regen is better. Note that the US spec cars won't regen in hybrid mode if there is no car in the front, even if the car is decelerating. Adaptive does seem to overcome this. Hybrid Eco Pro and Adaptive seem similar. But Adpative is little bit more eager to turn on ICE in uphill etc and your driving style. So I stick with Hybrid Eco Pro. I would say regen braking provides more range.

[nZtiZia]

in my experience, i don't feel any regen braking while in Hybrid Eco Pro when i take my foot off the accelerator. it feels like coasting in neutral. i feel regen braking in Hybrid (standard), though.

The 45e make no sense if you are consistently driving long distances. MPG is no better than non hybrid as the added weight offsets electric benefits. In my case I usually drive about 30 miles a day and my average mpg is well over 90. I fill the tank with gas once a year. There is no better car for that type of driving.

[BryanC84]

Most of my driving is pottering about.. so the range for me has been fine.
I've had my 45e nearly 2 years in July.

Some notes: Wheel size massively affects range. I have 21" and i've noticed I get up to max 40 miles.
Charging speed will always be disappointing. You use range quicker than it can ever charge in a short period - case in point.. i take my kids to school and then do our weekly shop.. probably 6 miles in total. Start with a full charge. Plugin when i get to shopping and it'll be 2 hours before its full again.
Regen sucks. Adds little to nothing.

I've done 17000 miles. Of that, probably 14500 have been pure electric. Damn OTA update wiped out the EV values so its currently showing 17k total, 10k EV.

Overall its been a great car. Its going next month as we have an i4 M50 on order.

I'm in Washington ... I use a level 2 charger and driving scared grandma I only see 30-32 miles of distance.... When we went to a hotel in Oregon recently I used their level 2 charger and it showed 39 miles of distance... Why would different chargers affect this ?

It's not an effect of different chargers.

because your most recent drive to Oregon was more efficient than your regular drive, you saw an increased range. if you repeated the next trip exactly the same way, you'll see 39 miles again. the electric range upon full charge is dynamically affected by many factors and not indicative of true range on your next trip unless you drive exactly the same way

Concur. Not having to go to a gas station is an underrated benefit, aside from charging being cheaper than gas….and the 45e being cheaper than the 40i after tax credits.

where is the driving style monitor in the car?

[ichibanb18c]

I'm located in SoCal too and can't manage to get any better than 28 mi on the battery. But only put about 600 miles on the car. Normally in hybrid mode. Normal city driving. People mention the hybrid eco pro mode but can't seem to find this.

[mnx5er]

I'm in Minnesota and getting around 35 miles off the battery. I drive in Electric Only mode. Ironically rush hour traffic extends how far the battery goes.

I get to ECO Pro by selecting Hybrid which brings up the screen and then I can select ECO Pro on the screen. I think you can also hit the Hybrid button multiple times.

Its under the driving information screen. Home —> Car —> Driving Information. I believe it only comes up if you are in ECO Pro mode.

I got into our 45e yesterday morning and noted 46 miles… this is the most I have seen. Driving style has been mostly flat expressway driving as of late, but lots of Air conditioning. I have not messed with range extension, etc. I was able to get very close to the 46 miles of range in combination city / highway driving. The range seems high. Has anyone else seen electric range numbers like this?

Also took 18.9 kW on board in last nights recharge…
