745e vs 730D MHT
Discussion
Hi guys, so I have a dilemma to choose between the 745e vs 730D MHT.. a nice dilemma to have!
I'm going to covering around 30K miles in the next 12 months so would prefer something waftable. Work has given me a generous car allowance and so I am looking at some very respectable lease deals on both of the above cars. They actually come out cheaper than the 5 Series or X5 and have more toys as standard.
My question is really aimed at anyone that currently owns or has owned the 745e. The fuel consumption claimed is "interesting." I cannot see how they get away with the claimed 121-146 mpg for what is essentially the standard 6-pot 3 litre turbo, with addition of a 13kw battery pack to aid economy. I do have a charging point at home, but is it substantially better than the diesel for the long run?
On the other hand, I currently have a 635D, E64 as my daily, and I love the B57 engine as I still hit 50mpg on a motorway, and around 40mpg on shorter trips. I can source the 730D for even less than the 745e. As both cars will be leased with full maintenance, I'm not worried about servicing and I get a mileage allowance as well. So what would you choose?
Leftfield from a mate is to consider the Tesla Model 3 LR!
Too many choices!

Is the 740i the same set up, but Petrol only ?
If so, the economy figures on that, may be more representative of what you’ll achieve
You would think so, but then hybrid technology is tied in so that it adds power when it sees fit.. this is the issue for me as I cannot see anywhere that accurately explains how and in what form. Either way it's got a big chuffing turbo so any scale of economy will be instantly lost the first time you enjoy the boost If so, the economy figures on that, may be more representative of what you’ll achieve
The car can recharge itself (don't get me started on self-charging hybrid rubbish) but I can plug it in before I set it off and that is bit I am interested in. I'm not worried about tax as the lease company deals with that, I just need to understand what is reasonable to expect as an honest MPG average.
Presumably if you cover 30K in a year, it will all be long distance driving? The 745e would have an advantage in city and short journeys, where you could use the battery most of the time and avoid refueling, but for long motorway driving nothing really beats a powerful diesel with the associated range.
As it is a lease, you don't have to worry about residuals either.
For your use, I would go 730d

Yes it's certainly looking that way. Same engine in my 635D and I absolutely love it although this has 8 gears compared with my current 6. It's also on a special deal and works out a few quid cheaper. Insurance is around £100 less to boot. Of course if I could save with higher mpg's then that wouldn't matter.
What's the short and long drive split? How many -10miles journeys vs +20 miles? I would go with a 730d (no 740d??), but if short trips represent the majority all the emission tat will get upset, so a 745e would be a nicer choice because you will be able to go on electric pretty much everywhere (see Harry Garage x5 45e reviews).
Any longer distance driving diesel everytime.

The headline mpg figure quoted is what the car achieved on the standard test. This is very high as the car can achieve the majority the test route on the battery so uses very little fuel on the test.
I had a PHEV (not BMW) a few years ago with a similar high quoted mpg figure. If I just used it for local journeys then it did all the miles on electric and used no fuel, so infinite mpg. If I went on a 50 mile journey then it did 25 miles on electric and 25 miles on petrol so still high mpg. If I went on a long journey then the 25 mile electric range was insignificant and so mpg dropped to a much lower value.
I think the power train in the 745e is the same as in the X5 45e, so you may find this thread of interest:

So the commute to the office is 45 miles round trip and I work from home for most days. I get a call to service a client and that can be anywhere in England, Ireland Scotland and Wales, for emergency response I will fly but for upgrades I will drive and stay in hotels. I can have a Tesla Model 3 LR for the same money but according to Tesla and Plugshare the charging infrastructure is not quite there yet in Ireland. Any longer distance driving diesel everytime.
Thanks for the headsup regarding Harry's Garage - I watched that and was thoroughly impressed, although with the X5, it does have a proper 22KW battery and the 7 is only 10kw which is a real shame. The lease cost of the X5 is prohibitive with the mileage that I think I will cover, but if it were the same or similar I would be ordering one. It's quite amazing!
Looks like another vote the trusted 730D then.
I might be a bit late for this one but having driven both I thought I would share. Let me start with MPG...
745e: driven for 4.000 miles, in a mix of motorways (mostly 70-80 but also 100 with some testing into higher speeds - 120-155) and some city driving (mostly in sport because I wanted to have the battery charged for some town driving and pre-cooling). Having only charged it three times it averaged 30.5 MPG. Should also be noted that the car was new when I picked it up, so it wasnt yet run in (which I think increases fuel consumption). IIRC, when doing slower speeds motorway only (600 miles, of which 100 miles at 60mph and remaining at 80mph and also some stints at 95mph) it did 34 MPG. The two times that I charged it, when starting the car it showed 19/20 mile range (which I think would be met under city circumstances but not under the particular utilization that I gave it)
730d: driven for 600 miles, mostly mortorway (I reckon 500 out of 600) at 60mpg with very little fast stints (rigid speed limits...) it did 39 MPG.
I guess both of the above are real life fuel consumptions; I am definitely not a gentle driver, hence the relatively low MPG even in the diesel I guess.
Other considerations: the 745e is much quieter which I think really suits the character of the car. It was also significantly faster; the way I understand it, the electric motor fills the gap in the turbo-charged engine; this works well provided that you have the battery charged, which is guaranteed if you drive in sports (even in comfort, but at a lesser extent); without battery power it gets to 140mph easily, but north of that is much easier with the battery helping). The gearbox copes well with the mix of powertrains and is very smooth, hardly noticeable the change between electric only and hybrid - not jerky at all as is the case in lesser hybrid vehicles. I did a couple of videos in both vehicles to check 0-62; the 730d was 6.5secs and the 745 was 5.3 ish (when measured, the 730 had only myself inside whereas the 745e had 3 people on board and absolutely full of luggage).
All in all, depreciation not being a thing, I would get the 745e; thats because I think the fuel consumption difference is not that high as to justify the lower power, rougher noise and lack of electric powertrain (which lets you be a very sociable person in city center environments and pre-heat/pre-cool the car through your key).

Hi Nuno,
Thank you for your detailed synopsis which is most appreciated. However, due to the time elapsed since I first posted, my friend has talked me into the left-field solution which actually arrived on the 19th. Needless to say now (and I wasn't sure then), this is the best decision I've made, and although totally the opposite of what I had envisaged, I am blown away by the car in general. 635D is sold, two XJS's are sold, only the Porsche left as an ornament when I can be bothered to throw more money at it.
Think I can finally say, "Bye bye ICE, hello electrification" and I would never have thought that ten years ago!

Work has given me a generous car allowance and so I am looking at some very respectable lease deals on both of the above cars. They actually come out cheaper than the 5 Series or X5 and have more toys as standard.
My question is really aimed at anyone that currently owns or has owned the 745e. The fuel consumption claimed is "interesting." I cannot see how they get away with the claimed 121-146 mpg for what is essentially the standard 6-pot 3 litre turbo, with addition of a 13kw battery pack to aid economy. I do have a charging point at home, but is it substantially better than the diesel for the long run?
On the other hand, I currently have a 635D, E64 as my daily, and I love the B57 engine as I still hit 50mpg on a motorway, and around 40mpg on shorter trips. I can source the 730D for even less than the 745e. As both cars will be leased with full maintenance, I'm not worried about servicing and I get a mileage allowance as well. So what would you choose?
Leftfield from a mate is to consider the Tesla Model 3 LR! Too many choices!
