Was wondering what kind of gas consumption you guys getting in P400 mode for the full tank of gas.
I meant by gas millege. Km or Miles.

Who cares? It doesn't make that much of a difference. You're not going get rich driving around in 400 mode as opposed to 500 mode.

There should be no difference as the car runs on 10 cylinders in the P400 mode.

So the only thing that can make a difference is your right foot.

For daily driving.


Why did you buy this car if you wanted to get mileage like Grandmas car? I fill up my gas tank every day (and have been doing so for the past year) to the tune of $50 per fill up. I'm proud to be a sponsor of the US terrorist campaign in the middle east to support our oil manufacturing companies.

Pah!! Be glad your not in the UK / Europe. Works out at approx $150 per fill. That'll make you think about using P500S6 all the time.

You got to be kidding me? 150x30=$4500/mo.


Wow, that's just insane. Didn't the gas prices come down after the Iraq war?


When I was in Melbourne, Au. I was shell shocked when I was walking around the CBD. I came upon a VW (I think) dealership and was walking outside when I saw a used 2007? E55 AMG Mercedes. It had 67k kilometers on the clock and they wanted $95,000 for it lol.

Someone also told me that a brand new M5 costs upwards of $400k out there. I wonder what the new M3 goes for....I only saw one, and it was when I was in Cairns.

Petrol prices here are an absolue joke. I know that you Yanks went mad when it went over $1 a gallon. Here your looking at £1.30+ per litre (which is about $1.95 a liter or $7.39 a US gallon). Imagine what it would be like over there if you had our prices. We just have to suck it up and take it. $55 of gas would only get me 70 miles here.

Prices didnt come down after either the 1990 or 2003 Iraq invasions. It certainly isnt coming down now they have found a huge reserve in Afghanistan and under the the Falklands. Its only gonna get pricier here too with winter on its way and truck drivers struggling to get to the stations (bad drivers). You do wonder where it'll end.

I can remember back in 1994 when I paid exactly $1.00 USD per gallon of gasoline around this time of year. I can also remember when a pack of cigarettes was $1.00 as well in that year. What in the hell happened? 1994 wasn't that long ago....

Are these prices the norm for all over Europe? (Italy included?)

I'm planning a 1 month vacation out there next year.

Yeah about the norm depending on where you are. I know its about 15% more expensive than the UK in Greece and on Crete. Nobody drives anything flash over there. France is quite pricey too.

I took a trip to New Orleans from Atlanta. Drove in P400 to New Orleans and averaged 19MPG. Drove in P500 back to Atlanta and averageed 21MPG. Stayed in (D) Auto mode the whole time. This was my only highway long distance trip in the M5 so I thought I'd experiment. I usually drive in P500 S5 around town (manually). I was happy to get 19-21MPG in the M5 either way. Yeah for the 7th gear.


My guess is it takes more gas to go the same distance in P400 vs. P500. I noticed a delay in the kick down in P400 while passing a car or going up inclines, etc. vs. P500. I'm not sure if this theory holds true just a SWAG at why I had better MPG in P500 with the same route there and back. Little variances in the drive/trip may also contribute but it is safe to say that you won't see any MPG improvement in P400 from what I can tell. Anyone else have different results?

My experience of tune changing (which is basically what going from 400 to 500 is) is that the higher the output, the less gas you have to inject to achieve a given target, ie. 0-60 in 8 seconds with P400 will require more gas than 0-60 in 8 seconds with P500 because the engine is running more efficiently in P500 and you dont have to press the pedal so hard. I think thats right anyway.

Ive been driving in P400 for the last 2 months since i bought it just learning the cars 'traits'. Now im happy with it im gonna stick more with P500. My average for P400 was 13.2mpg, i'll see if it changes.

So, whats the point of P400 if P500 is more efficient??

Can you set up the car to just start in P500?

I dont think there was ever any point in it. I think its a bit of a 'look what we can do' shout at the likes of Audi and Merc and to impress the public when it was launched.

Can anyone tell me why the gas mileage is so bad in our cars? I used to drive a blown '03 Cobra with 445 rwhp and 435 rwtq and could easily get 23 mpg on the highway cruising along. I know our M's are 500 hp but they are only 383 tq and very top-end oriented. I would think keeping it in the lower revs would yield much better mpgs...

And FWIW, I don't really have that much of an issue with the mpg's, its the trips to the gas station!!! Major engineering flaw by BMW.
