Turbo cars don't love running lean at full throttle is what I was suggesting, but it's a thread about 750s so this is boring!
That’s quite a moving of the goal posts, no-one said to do anything at full throttle.seefarr said:
if it runs lean while you're on it, you'll do an engine.

Fuel tank capacity: 72 litres
You could try flicking to track mode where the fuel is shown as a % rather than range, at least that would get rid of the inherent guessing of the economy. Unsure how much 'reserve' there may be below zero. At 25mpg the full 72L should give 395 miles.
72 litres, even when the car is screaming about an imminent dry tank I can't get anything like this amount into it! Fuel tank capacity: 72 litres

Not out in the car today because of the bloody rain but I can't wait to try track mode thing, thanks.
I've never noticed that it changes to a percentage, does the 720 do that too?

When you put your card in the machine will pre-authorise the maximum amount it will allow you to spend on fuel. So €130 perhaps (but it will vary by which petrol station you use) and that is the amount that will show on your statement until it reconciles with the actual amount spend you did on fuel. This is usually a few days later and in dozens of French fill ups I’ve never had a problem with being charged the wrong amount.
Have a great trip. Look forward to the updates.
Thank you Deuce this is exactly what's going on, don't know why I didn't suss it. Have a great trip. Look forward to the updates.
One refill was 89 euros and they took 175 quid off me, but that would probably equate to 200 euros allowance. I'm so glad I didn't sit on the phone to the bank for an hour so they could point out my stupidity!
How have I never noticed this before on previous trips? Got to keep a closer eye on the finances

You may not want to do this while on a trip, but I’ve generally run my cars to empty while carrying a few litres of fuel to find out how much range is left after it says zero.
Of course you need to pick your venue, but it was worth doing for me as I do like to know how far I can actually go before running dry.
Each to their own Ken but doing that really doesn't appeal to me in a car well North of 300k!Of course you need to pick your venue, but it was worth doing for me as I do like to know how far I can actually go before running dry.

On my 720 I've found that when the range is down to about 30 miles you can only squeeze 47 litres in, so there's a lot left out of the 72 litre tank. I find the way it calculates range to utterly frustrating.
Once it gets into the last quarter I am looking for a decent petrol station.
On a recent trip a my friends GT3 Touring used €0.06 less fuel than me having both filled up at the same in before crossing to France.
It does seem to be an odd way of doing things. Although that little frisson of panic as it suddenly starts plummeting when your miles from anywhere certainly let's you know your alive! Once it gets into the last quarter I am looking for a decent petrol station.

McLaren confirmed 72 litres tank capacity to me. The gauge is basically useless, as it was on the 720. I think you need to differentiate between motorway and any other kind of driving. In a steady state cruise, I work to a 300 mile range and basically ignore the gauge. Reset the trip when you fill up and refill as you reach 300 and you should end up putting somewhere between 60 and 65 litres back in.
In "spirited" driving, I refill a) when I can and b) when the gauge hits red, at which point I'm probably putting in 50-55 litres or thereabouts. But since proper use sees about 10mpg, the remaining range at that point is somewhere around 40 miles to bone dry.
The 750 is notably less fuel-efficient than the 720, presumably mostly because of the shorter gearing.
I've got to say I admire your bravery mate, I know you've done an accurate assessment and I'm convinced you're correct but I don't know if I have the balls for it! I knew I could get more than it was reporting but ignoring the gauge completely and just counting the miles maybe beyond the limit of my nerves!

Even when you know it's wrong there's always that nagging doubt!
Agreed on the spirited driving side, no chances taken there, I'll always keep a decent buffer in the tank as these things will absolutely drink it when you're enjoying yourself. I had a lambo that gave you the actual in the moment figure, when I was going for it it would drop under 5 mpg instantly.
And yes, the 750 is definitely thirstier than the 720, first thing I noticed.
Has to be the shorter gearing. Unless we're getting quicker as we age.

Brad, where's the trip write up?!
Well I'm not sure whether to do it this year. I know it's a new car and all so that would be of interest but I'm not sure how much appetite there is for these blogs year in year out. Man goes to Europe, does a lot of driving, gets drunk and does stupid stuff, the format may be getting tired.But I'll stick something up if people want it, I have no shame!

Pls do it’s always an enjoyable read and with the new car as well an added bonus!But I'll stick something up if people want it, I have no shame!

I’m sure it can be a pain to write up so understand if you don’t fancy it but would still interested to know your route and any hotel recommendations. And at least a couple of pics of the new car.

Same here, often inspires me to get another trip planned. I’m sure it can be a pain to write up so understand if you don’t fancy it but would still interested to know your route and any hotel recommendations. And at least a couple of pics of the new car.

77 miles, Reading services to Severn view services. Google 1hr 21. Actual 1hr 04 mins (average 72mph) so not an economy run and plenty of hills. The MPG went down quickly when we crossed the bridge into Wales. But that's the wonder of a McLaren over an Italian equivalent, they can cruise the 'boring' bits of a long Euro tour much more efficiently and with no performance compromises when you get to the twisty bits. It highlights the engineering excellence and for me why McLaren have an edge on other supercars. My typical M-way MPG is around 36 so this was better than usual, and it doesn't need super either, in fact I would say it runs even better on 95 in terms of aural stimulation / whip cracks.
