Starting with depleted battery it still maintained a 9L/100km over the long trip which is less than my G81 would have done.

in eControl mode EV is definitely still on, but rarely used. fuel efficiency goes right to the drain when it's trying to recharge the battery (as expected).

that's very good MPG!

Nah it’s driven hard. Similar to f90.

Ok! but shouldn’t the hybrid driving mode help out enhance the mpg?

Why do you think its not right?
Close to 600 HP (ICE) moving 5400 mass in sport+ mode needs serious gas burning…
My M8 consums gas about 10-12 mpg in Sport+/S3 when I drive it the way meant to be driven LOL

Agree if it’s solely on ICE , my point here, what is the EV’s contribution to mpg?

When driving in sport or sport plus in hybrid mode, the engine does not turn off. If in comfort, which I don’t use at the moment, it will turn the engine off/on when it chooses. Then you’ll see the number go up.

contribution to MPG is from using the electric motor exclusively...so you go more miles without using gas.

For example, in my 330e this month I've traveled 208 miles, 164 of which in eDrive (all electric) and 44 miles without eDrive. This translates to 168 miles per gallon

[Khoispring]

lol guys I am confused ! So do you recommend to run in sport only or econtrol to run in the ICE lol the time ? I mean as long as my engine is running all the km marked wether I have the battery to help in performance is just a bonus right ?

[thaalrasha]

I did a 537 km trip which is almost a full fuel tank range, with little to no battery. Mostly motorway and maybe half an hour of congested city driving.

I'm pretty impressed by the consumption of this V8 given the weight of this car. I get better fuel efficiency than my G81 and on par or better than the G20 330e i had few years back. Without the city driving this would have gotten to 9L / 100 km ranges. Cars was left in hybrid mode and while the ICE was doing it's nominal job on the motor way i could see the EV power train was helping when little boost of power was needed while it remained in 8th gear. It seems to me BMW nailed the efficiency of using both power sources. Software seems to have progressed leaps and bounds compared to the G20 i had.

I have my deal made for exactly the G99 I want and all I need to do is press send on the email... and I'm hesitating. I am in my 50s and have nothing left to prove in terms of "real" M cars or hot laps or maxing it out on the autobahn- I've had those years in M3s and on S1000RRs. Now, within striking distance of being a grandfather, I feel like the G99 was designed with my stage of life in mind. Haha- sorry- I don't want to ruin it for anyone. Clearly, it was built for young people like you. I was kidding! =D

Here is the thing- the hybrid with electric mode is for regulations and ICE-forbidden city-centers that we don't have in Florida, so I need a reason for the extra 1000 lbs. I need a few more miles per gallon. It isn't a money issue and it isn't even an environmental issue per say- but I need something for the increased complexity and weight- performance certainly isn't it. If you aren't getting better mileage or performance and you don't need to comply with zero-ICE zones... what is all this complexity for? Especially given that I will still be paying a gas-guzzler tax. Having the first M wagon ever (in the US) is good- and that is what got me to consider the purchase but any meaningful increase in highway mileage would seal the deal. The XM data from the EPA does not make me hopeful. Forget around town- assume I am taking a hundred mile trip, or two hundred. Are the folks saying 23 mpg optimistic? Honestly, I'd take 20, but I am not sure I can accept 17 because I can get that with an ICE (the same ICE, actually) and skip 1000 lbs of technology.

Thoughts, disagreements, or especially data would be welcomed. I have read everything on Bimmerpost including this thread- Thaalrasha's post was very helpful. I just want to keep the conversation going and perhaps get a few more data points. Thanks!

It certainly should have great MPG on highway cruises (relatively speaking, of course). I've driven a total of 1500 miles with my G90 - likely ~70% is highway driving (hybrid mode) in express lanes going ~80 - 90 MPH. Remaining is short 5 - 10 mile trips mostly in hybrid, though some definitely more 'spirited' M1 / M2 driving...

Total average MPG is 38... for a 4.4L v8... pretty damn good.

Looking forward to this at some point!

Are you recharging each night with level 2 charger?

[Oh_That_Guy]

That is really helpful. Thank you. I have seen enough 23 mpg and up discussions that I am ready to order. I just got a bit rattled that the EPA data on a similar drive train on the XM is 17 on the highway. There is a specific 125 mile drive I would likely make that I would be able to charge fully before both directions- to be honest, I am rarely far from a charger before and after drives, even long ones.

The hybrid fuel economy come from 2 main use scenario, according to my experience :
1- on short commute to and from work you can get away running pure EV or almost. fuel economy is almost 100%.
2- on longer journey, the V8 will do most of the mileage at constant high speed and the hybrid and EV drive train will take over in slow city stop and go traffic tremendously as the EV part is good a delivering torque from stop. The fuel consumption in the end will look like a constant highway consumption and the average won't be ruined by having the V8 in its less efficient use in stop and go traffic in cities.

FYI, my service advisor strongly encouraged me to drive in non-electric mode as drive in M1 or a setting that forces the gas engine to run during the first 1,000 mile break-in. If you drive in electric mode primarily in the first 1,000 miles you are not really breaking in the engine properly.

What kind of MPG do you think you are going to get from a heavy sedan with over 700hp that is not driving in hybrid mode. I drove mine thru break in mostly M1 mode (sport/sport plus) to make sure gas engine was on over 80% of the time and I averaged 14.5-15.5MPG with spirited driving. I’m sure that will get closer to 16-16.5 after break-in and if you want any better than that then drive more in electric or hybrid. I wasn’t expecting more than 15, especially after having to pay a gas guzzler tax!

Thoughts, [...]

If you can’t live with 15-17 then you should probably consider getting an i5 M60i instead. I definitely didn’t buy mine for gas mileage. Bought for performance with flexibility to drive in pure electric mode on most of my daily commutes to office, golf course, etc if I want more efficiency.

G80Power- I don't think we are on the same wavelength but I do appreciate your input. I am not interested in a different model or mpg except that mpg should be better than the last generation in the absence of other benefits from the new drivetrain. I'll try to be more clear about my concern. If the G90/99 offered performance gains I wouldn't care at all about the mpg. But it doesn't. In general, when engineering a replacement for a machine, if you dramatically increase the complexity (and in this case weight) of the machine you need to offer some benefit or form of offset. In automobile engineering that is often performance gains, but there are none here. There are regulatory gains but not in the US. That really only leaves efficiency as the area in which the BMW team can justify to the American market that their new complex drivetrain is superior rather than simply more complex. That is my interest in improved mpg.

I get what you are saying and what I will say is they the G90 is definitely different than the F90. I have now had both and also just came out of a G80. The G80 and F90 were both more raw and felt like more in your face raw power and more high strung. The G90 is heavier but also smoother. While it will be argued which M5 is faster, it seems to me Enron seeing videos that the G90 is faster in a roll race. What is different to me and not sure if better, is the G90 is some much smoother and quieter so while it is moving very fast, it is very deceptive because it doesn’t feelmlikbyou are going as fast. The technology is also way more advanced and I love that and new screen screen. I get in an F90 of 8 series and they just feel so dated to me now when I don’t see the I drive screens. I also rent BMWs almost every other week when I travel some have been driving all the models and have just gotten so accustomed to the new screens that all the other models that don’t have them now feel dated.

Regarding MPGs, I think the G90 is better than than previous with significantly more power and can be ALOt better depending on what mode you want to drive in. I personally like to go fast most of the time and it seems that I am averaging 2-4 more MPGs than my F90 but then again I didn’t buy this car for MPGs

[Oh_That_Guy]

Thanks for getting back to me. The fact that you, with your focus and driving style, are seeing a little better mpg even in spirited driving is really useful input. Thanks for sharing that. Hybrid technology is hard to justify on highways because "peak levelling" isn't anywhere near the gain of in-city regenerative braking. Even so, in theory we should see a small mpg gain on the highway. My mind is made up- I'm ordering the wagon. The dealer texted me last night that they have a G99 arriving and by some miracle it is available- but it is black on black and I'm an old school Alpine White guy. I don't mind waiting.
