Range on one tank

250 miles on average - occasionally more but not much. the range indicator shouldn't be trusted although I've been down to 0 a couple of times.

I usually get 440ish miles to a tank. On my long road trip, setting the cruise to the speed limit and just going, I got a couple of tanks at 550 miles, with 2 people and all our stuff in the car. I'm actually impressed.

I can believe that, I was impressed with one 300 mile freeway drive I took where I pretty much stayed at the speed limit trying for a mileage run. I filled the tank at the beginning and refilled at the end for the most accurate reading, rather than rely on the BMW calculator and was pleased to get 24 miles per gallon. I had two or three short bursts to over a 100 mph during the drive, but that shouldn't have affected mileage much. My previous car was a 1994 Lexus SC400 with the 4 liter V8 engine, and it rarely would achieve 20 mpg with its stock 250 horsepower motor on a freeway drive.

Are you sure thats an M5!!, thats incredible MPG.

i think one offs on long road trips are the exception. people want to know day to day usage.

Yep mine so far on 800 miles is 25.9 MPG.

i have done 63km (missed petrol station racing with another guy) on highway doing 120km/h after m3 range indicator showed me 0, so i do trust range indicators! it does show 0 long before u run out of fuel

Day to day to the 440 miles to a tank. It's down to driving style, how much traffic there is, and what your proportion of cruising to sat at traffic lights is. The reason I get to work before 7am is so that the roads are empty, and so that I'm not in the afternoon rush hour either. It really, really helps. 25 minutes at the speed limit and 2 minutes at lights, rather than an hour in stop-go traffic is way better fuel economy.

[Neil McRae]

is your M5 on a transporter truck during this? LOL

Picked up mine 1st September (details to follow once I can create post). Have only done 150 miles (+ 5 miles at delivery) and averaged 25.4 mpg (UK - 3/8 tank of fuel used), so should extrapolate to approx. 400 miles from a full tank. This is mostly gentle motorway and A road, but varying speeds and manually going up and down through gears during the running in period.

I had a pre-LCI dealer demo for half a day and, with mixed driving, I averaged approx. 25 mpg in that car.

[elitex]

Drove up to Ontario and Ottawa from Atlanta and got roughly 23 mpg. This is with trunk full of stuff along with my wife and 2 year old.

saw a nice MCB M5 in the underground parking lot of my hotel in Ottawa.

[jet888]

Great data gents.

Im showing it to the missus to prove its no BS that this much larger, more powerful machine is more frugal than my M3

[Neil McRae]

who buys an M5 and doesn't h00n?

jet: honestly whatever you are getting from your M3 add 2 to it for best scenario:

As you can imagine my miles per tank are low!

I've also found that commuting outside of rush hour on mostly freeway brings the economy way up - cruising at the speed limit rather than stop-go all the time is HUGELY more efficient. Likewise, getting up to speed with a moderately quick acceleration - quicker than most other people here, but no risk of wheelspin, and then cruising in a higher gear is more fuel-efficient than cruising slowly up to speed over the course of a mile.

You can view braking as fuel inefficiency, too - if you accelerated up to a speed, and then need to brake to match the speed of the car in front, you could instead have not accelerated as much and saved some fuel. Do I do this? Sort of - I leave a bigger gap than most people do here, so that I can lift off instead of braking, more often than most. I wouldn't say I'm a hyper-miler, not by any stretch, but I lived the first 30 years of my life in a country where fuel was 8.05 US dollars per gallon when I left, and I lived 40 miles from work. It turns out, some of the habits die hard.

One of those habits is the long-cut - instead of sticking to the main road with stop-go traffic, get onto a longer side road, for better fuel efficiency and consistency of journey time. I do that here on my way home - there's a weird set of lights and streets that means heading the wrong way first gets me past a traffic jam I would need to join the back of if I went the correct way first. I don't want to sit in traffic - sitting in traffic is wasting time and fuel.

Did you convert that to miles per US gallon? They're different. It's 10.99 miles per US gallon.

US gallons, like their pints, are smaller than the UK ones, by about 20%. So when we go out and drink 10 pints, that's 12 US pints.

[jbomb]

Nope I didn't convert to the US although I'm sure the OP is from the UK and as he did ask the question I didn't see the point in converting.
Nice explanation though

[UniqueCheese]

Hah. Oops. I hadn't spotted that. Well, I can go back to speaking British then, despite being in the US

[wrsbmw]

I get 23mpg hwy and about 14mpg around town. Around town tanks are usually around 250 then I fill up at 1/4 tank. I can easily go 400 without a refill before 1/4 on the highway. I don't like letting it get to fuel reserve.

[JOHNBMWM5]

I got my worst MPG this week, with easy driving on open roads
I filled the Car with 97 RON Sainsburys fuel , car hates it, 23.6 MPG.
Thats the worst running -in MPG I have had.

Tesco 99 from now on.
