From the BMW info on the upcoming X5 xDrive45e:

"BMW says it will sip just 2.1 liters / 100 km, with equivalent CO2 emissions of 49 g/km."

Google converts this to 112 mpg. Clearly something must be wrong. How can PHEV of the X5 get 112 mpg? That's insane. The Honda Accord Hybrid gets 47 mpg.

I believe it has to do with how they word it. Per their release info, that 100km is combined fuel efficiency, and the 45e can go 80km on electric alone. So I'm assuming what they are referencing is if you have a fully-charged 45e, and get the maximum possible electric and fuel efficiency(as they do in "test labs", real world we know this won't happen), then you would see that type of fuel economy.

As for the Accord, is that for the regular Hybrid, or a plug-in hyrbid like the 45e?

accord is a regular hybrid, not plug in

[JayPichardo]

It is probably MPGe

[athanyel]

I'd lean towards MPGe as well but even that seems a bit high. For comparison, take a look at the official numbers for the 2018 X5 40e, 2018 Audi A3 e-tron, and 2018 Chevy Volt:

https://www.fueleconomy.gov/feg/Find...39589&id=39190

The X5 40e gets 56 MPGe but only 24 MPG. The Volt is a lot more efficient being smaller and lighter car with a much larger battery. That said, it only gets 106 MPGe.

So...I think we'll just have to wait and see.

Any real-world reports of the actual range of the 45e? I.e. with battery and gas tank full, how far can you drive on the highway at, say, 70 mph?

[W0ut]

There are users on this forum that already received their X5 45e.

I believe a few of them stated 5,2 liter/100km real world usage. (45mpg?)

With a plug-in hybrid the mileage depends heavily on the type of usage, driving style and if you keep the battery charged.

So I have just done my very first >100 mile drive in my 45e. 3 miles in the city, 80 miles on motorway then 20 miles of A road. I started with a full tank of petrol and only 11 miles on the battery.

Ended with an average of 39mpg and 25 miles of the journey done on electric. So the engine is still very new (just 185 miles on the clock at the start of the journey) so I'm sure things will change, but I was a little disappointed that the petrol efficiency was not higher, but the car is obviously pretty good at energy recovery, given how many miles I did on electric only, from the starting point. I left the car in Adaptive mode all the way

My official paperwork states 39g/km - so even better :-)

mpg with a hybdrid doesn't make sense. After 6 weeks I have driven 2/3 pure electric (daily home-work commute) so my mpg is way higher.

It all depends on how you charge the car and what your driving circumstances are.

When I have the battery fully charged it claims to be able to drive around 64km.

If you do a lot of driving in the neighborhood you can drive all electric and then you have 0,0l/100km so your average goes down very easily, but if you drive highway with speed around 120km/h then it quickly goes up and you definitely don't want to use battery control to charge the battery when you are driving in the ICE as it drives your average fuel consumption even higher.

If you do mainly highway and long distances, this is not a very fuel efficient car as its battery lasts for about 50-60km and then the fuel consumption goes up quite quickly.

Overall the car drives great, the power is there and in full electric mode the car is very relaxing to drive, even with the 22" wheels. On the highway, the engine is good but consumption goes up as it's a heavy car.

For me, the X5 would be the ultimate road trip car - comfy with long range. If the 45e has less total range than the 40i, ... than it wouldn’t be worth the decrease in cargo for me.

Do you have 19inch rims?

We got the paperwork for our car yesterday. When I enter the VIN in the website for registraions it states combined co2 31g/km WLTP (new standard) and 41g NDEC (old standard)
That is 1,3l/100km, 177mpg.
So officially with a full tank of gas you can drive 5188 kms / 3242 miles. Hilarious

Not calculating regenerative braking, 45e total range should be 5-10% less than 40i.

But I would love to hear from the owners of 45e what are they getting on weekend/long trips?

[AndroidRobot]

meanwhile my 50i gets 12-16mpg very reasonable for a fun time. I think the above comments nailed it. BMW is using the best possible scenario of a fully charged battery going the most efficient speed allowed for the test and putting the engine under the lightest load they can while accelerating within these parameters. BMW says the 50i gets 17 city, unless you never touch the gas that's not possible in real life. odds are the 45e will get maybe 50MPGe in reality Time will tell when people start getting theirs delivered in the US
