Honestly the new 45e range of BMWs seem like the best of both worlds. 6 cylinder engines mated to a decently sized battery for proper hybrid driving support in a bigger car

Unfortunately it is only the X5 that has the decent size battery. The battery on the 545e is much smaller which means it has a far less useful range and more expensive on company car tax, too, despite being cheaper to buy.

Oh really?
Seems like a strange move from BMW, as it would have surely helped with the sales?

I'd imagine its a technical limitation.
Nice, I'm looking to do the same with a Volvo hybrid, due to towing, EVs just aren't ideal yet for that purpose, it's not so much the range you can plan for that, its the charging whilst hitched up faff, severely reduced range and then finding a fast enough charger to not takes hour when you do find one on route.
Figured even if I can't get a good electricity tariff and the Hybrid only did 2 miles/kW its cost on my current tariff would still equate to 45-50 mpg, I'd be lucky to nudge 37mpg on a run in my diesel tank, in its predominant city driving/commuting use it is 21-23mpg so I am pretty sure I can only win with a Hybrid treating is as an EV most days and petrol when towing, I'd imagine once towing the petrol will be similar to the diesel with low 20s so no change there.
Of course was envisaging getting more out of the battery, above you say 3.4kW per mile (7 mile range
) , I assume you mean miles per KW, if it was miles per Kw you'd expect to get your entire journey on EV with a range of 81miles, sounds like you don't with 42 miles out of 24kW battery in the X5, that's 1.75 miles per kW assuming depletion by the end?

Perhaps, still a PITA though, as it still feels like many hybrid vehicles are the worst of both rather than the best

Yeah absolutely but in many companies a company car is still commonplace, so it’s great to see options which are cheaper and better for the environment.
I'm not really sure I understand why it has a 3 litre turbo petrol engine rather than the 3 litre turbo diesel engine. Zero emissions running around town and lower CO2 and lower fuel consumption when on a long trip.

I did mean miles for kWh! On the BMW its only recording the journey times when on pure EV in those figures. Obviously all the times its running in conjunction with the engine aren't included.
Thats the issue with Hybrids. The 3.4 miles per kWh sounds great, on par with an EV like a Tesla but its a false figure to a degree. The tesla has to use its EV motor for climbing hills, acceleration, going faster than 68 mph and still comes back with 3-4 miles per kWh. The Hybrid cheats by removing this from the figure on the dash.
Yes, I could perhaps "do" 80 miles on one charge in theory as if I am doing once section of my journey to work at 50 mph I can go 10 miles and only use 1/8th of my battery power. But that ignores getting up to speed or any hills.
The reality is you use up the rest of the charge in the batteries on acceleration/hills and high speed.
I suppose I could put it in all electric mode and stay below 68mph and go very slowly up hills etc but I bet I now longer show 3.4miles per kWh and the reality will be closer to 2 miles per kWh.
Its only a 130bp EV motor trying to push around a car which now weighs 2.5 tonnes.
So I am quite happy with 40 miles of journey each day been done on pure electric which i charge up at 5p per kWh at night.
ANd like you, I am then prepared to take the hit when towing and realise 20mpg (or less). Wont be any worse than towing on the v6 diesel. Towing 3.5 tonnes kills most car's fuel economy, I used to own a Daihatsu Fourtrak and that would only do 16 mpg when towing that weight.

Is it Mercedes who do hybrid diesels?
Seems like a great idea, cutting emissions in towns and then as you say, you get the longer range of a diesel.
Finding good balance is important
Yes diesel hybrid which I think is the 2.0L unit, though badged as x300dh. They're decent from what I've read/heard.
The Polestar 1 (PHEV) has a 34kWh battery -> about 80 miles of range.
Thats the route Mercedes went (albeit they only put a 2l 4 potter diesel in their GLE hybrid). I reckon a 3l diesel x5 with a 24kw battery would have sold like hotcakes.
I did see the new model next year gets the fully tuned 3l petrol rather than the detuned one in currently and it gets 500bhp combined as opposed to the 400bhp the current model has. This one shifts already with a 0-60 time close to 5 seconds in real life. I expect the new model will have sub 4.5 second times.

New Range Rover PHEV is pretty meaty - Straight six petrol and 38kWh pack. P510e with just over 500bhp is 5.3sec to 60.
Diesel is just a pain for aftertreatment and dosing with all the HV kit - particularly now we have started doing them properly with the battery under the floor.

Thats a decent battery pack. What's that, an 80 mile pure EV range? Will also mean almost minimal BIK as well (4% so £133 per month for a 40% taxpayer) . For those people not yet fully convinced by EV or need to tow their little princess's pony around.

70 in the Range Rover. I’m assuming the sport will be a bit higher.
Lol 70 is exactly whre the bIK drops from 7% to 4%. Funny that
Of course if you make a PHEV with 130mile EV range then it drops to 1% the same as an EV but doubt a 130 mile range with an engine is very practical due to weights.
That was my plan but the off peak tariffs are all locked out....missed the boat....grrr, hopefully they come back
I'd be very happy to get 40miles that would do a couple of days of the daily grind for us, Volvo only has a 18.8kw battery though, 15 usable, assuming a similar 1.75m/kW that's about 25miles just enough for daily mileage, I'm hoping it'd be better though as the car will never crack 50mph as it is all city driving and WLTP states 48miles.
Might need to take the missus to have another look at the X5 though, I'd prefer it.
I suspect you will do better than 1.75. Plus I dont mind the odd bit of engine kick in. I filled her up when I got it and the way its going those 15 gallons are going to last 3 weeks or more, maybe a month if i stop playing around with sport mode
. Better than the weekly fillup on my 3l v6 diesel Touareg anyway.I think you can still get Octopus Go on 30p day and 7.5p between 00.30 and 04.30
