M5 WGN - Hyper-miling?

[omniflow]

Not sure if it's anyone on here, but I saw an E61 M5 yesterday somewhere between Aachen and Calais, and it looked like he was hyper-miling - doing about 50mph about 10ft from the back of a truck.

Now, I know that you can't stop in France or Belgium to re-fuel, but I would have thought that even a V10 M5 could make Calais at a steady 80mph after a final fill-up in Aachen.

I didn’t realise that - is it the case that if you did have to stop and fuel in those countries you’d have to declare this and comply with self isolation requirements etc?

Not that I’m planning a trip any time soon...

Apologies - of course you CAN stop in France or Belgium to re-fuel if you want to, but in theory you then have no option but to "mingle" with unclean folks and as a result will have to quarantine for 2 weeks when you get home. However, it doesn't look like anyone is asking the question, never mind doing any actual checks, so the entire thing is a bit of a farce anyway.

Owning an E63 M6, which is about 150kg lighter than the E61 M5 i don't think I ever saw 300 miles out of a tank. Obtaining 18mpg on a run was good going.

220miles from Aachen to Calais might be on the edge in a fully laden touring.

Agree... I had one of those when they were first produced. The combination of serious thirst and a small tank was killer. I was getting about 10 MPG in the city, and 18 required some very relaxed driving. Great engine though!

I used to do something similar along the A14 to pass the time (dual carriage way, chock-a-block with HGVs) when I used to have a regular Derby / Cambridge commute, 30 mpg was easily achievable at 60mph with a gentle right foot. Would easily get 300+ miles out of a tank and our semi-regular jaunts over to Anglesey would return 24/25mpg with the family in the car.

The E60 M5 is the only car where I had a 10 litre reserve tank permanently residing in the boot - the 70 litre fuel tank was pitiful, 100 litres would have been more adequate.

You can fill up without any issues. No-one will ever check and it doesn't matter.

I'm pretty sure refuelling is allowed if you're transiting a country. If you have a Maccies meal, go sightseeing and pick up a hitchhiker, then fair enough, but just refuelling & paying for it? Of course the rules don't specifically say that, but common sense does.

Love it!

Got to ask: were you desperately conserving fuel, or is it the same every journey?

And how did you find this thread? I hope you always drive the same way and then scoure the Internet after every drive in the hope of finding someone who has commented on you

I was 2 hours early for the eurotunnel so was just plodding along,,
I got sent this thread by a friend

Excellent!

And having seen your other post showing the car on track, I assume fuel conservation isn't a top priority for you. Unless you were pootling around there too

Got to be one of the least likely hyper-milers ever.

Haha some might say i was slow but hey, fuel economy isn’t an issue as i daily the car and i'm used to the single digit mpg around town

Brilliant - I thought it might be someone on here. I was the bloke that passed you in a black Maserati Gran Cabrio. We were also 2 hours early for our booked train, but I'd paid for FlexPlus because it was only about £30 more than the basic fare (switched from Ferry to Tunnel whilst we were away, definitely paid peak pricing for the tunnel)
