Hi, I am considering buying a second hand 2016 330e. As well as many localised trips I often will drive 150 miles in one trip (private not business), often I would be able to recharge at the other end, but I do also do a 300 mile round trip where I may not be able to recharge during it.
My question is what mpg do you get out of the 340e during such long motorway based trips, 150 mile and / or 300 miles.
Thanks
Dillon

You will get the same mpg as the 320i so around 33mpg on a long run. The battery is only small and will either enhance the performance up to 330 standards of offer around 20mile of pure electric when charged. I nearly bought one this year but seeing as it would be mainly used for short local runs i deemed a BEV more useful as less to go wrong with it in the long run.

I'd dispute that. I have a 530e (so same/similar power train in a heavier car) and when I do 200+ mile runs, I get a tad under 50mpg. I guess that comes from 20 'free' miles from the battery, plus regen giving you a few more, too. I don't brake often on motorways, but I guess I lift off often enough that it manages to get something more back.

(Based on my VW experience), it depends a lot on the journey as well. You don't just have 20 free miles, you have battery power to use when the engine is inefficient (start/stop, traffic, etc.), and the ability to switch off the engine under very light load (which my car frequently does on the nice parts of the motorways). A PHEV isn't just x miles EV, followed by x miles in a heavy ICE car, it's also using the motor to assist the engine.

One cool thing I've noticed in my car (don't know if BMWs do the same, I appreciate that I'm in the wrong part of the forum...) is that on the motorway, it'll sometimes use just the engine at say 45mpg, and sometimes it'll use the engine and a little battery power to get 65mpg and 30mi/kWh (both going the same speed) - basically using the battery to get a little fuel efficiency boost. With little PHEV tricks like that, you can certainly outperform the equivalent ICE car on a long journey.

But sure, run the battery flat, and it's just a heavy ICE car.

Anyway, I'll stop talking about the wrong brand now...

I was advised by BMW to stick it in sport mode and SAVE mode, and on a run it effectively charges approx 1 mile to 1 mile covered - much faster to recharge this way. So every 20m you get a freebie 20! Doesn't seem to upset mpg noticeably. I've got the 225xe - similar set up to yours I think.
Even in electric and sport mode, it recovers more electricity than without sport mode on.

Who advised you? The salespeople? Everything in the eDrive section of the Connected app points the user towards eco pro (driving mode under efficiency). Of course it's faster to charge the battery in Sport and Save mode, but it's hardly free as you're burning fuel to charge the battery.

The PHEV specialist. Try it. It works.
Eco mode doesn't charge as hard.
When you have no electric save mode generates off petrol engine. It's quicker in sport mode.

What MPG do you get?

That might be why it doesn't make much difference to your MPG. A petrol generator (which is basically what you're using the engine as) is not very efficient, so you'll get a lot of conversion losses by charging the battery from it. How significant that is to your overall MPG basically depends on whether you're hooning it or trying to maximise MPG. Charging the battery from the engine on my VW easily costs me 5-10mpg when driving carefully, but lead boots bring it down significantly more.

Well like I said it's not really noticeable so for me charging to get electric miles at the other end of the journey is cost effective as I'm getting 30-40 e miles instead of 15 at the start.
I've also noticed e supported petrol running doesn't really add much to petrol mpg.

45 petrol and 90 it's says on electric. I don't drive particularly Eco...
M/KWH electric consumption on the trip computer can be misleading!!

Fully charge the battery and drive 200 miles - it will show about 30M/KWH as used 6KWH but most of these miles will have been provided by petrol - not electricity.

Similarly the MPG figure will include some electricity.

Easier to measure petrol consumption on a long 400 mile motorway run , at 70/75 mph on cruise control I get 48mpg actual ( 50 reported ) full tank to full tank in comfort mode with battery empty to empty - return was 53 actual 54 reported.

Sport mode will force the ICE to run, so any excess power will be used to charge the battery, but you will never get all that energy back - better to run in standard hybrid mode and the car will adjust the blend depending on battery charge, throttle demand, some topography of the road from the map, and prefers EV when close to destination.

I'd agree with those figures, on 300 mile round trips in my 2017 530e. Driving style makes the biggest difference as Blanik says. Easing off on the accelerator and using regen braking as much as possible will add miles on a long journey. Right now it says avg 58 mpg, but most of the time we are using in 100% electric mode around town so that mpg is irrelevant as it doesn't include the electric miles.
