Am curious if the consumption is similar. I know we are comparing a v8 and a v10 (and yes I can afford to run either before the usual nonsense replies start)

I am considering swapping my 996 turbo for one of these. The pork id returning an average of 12mpg.

My guess would be M5 - around 15mpg and M3 - around 20mpg. Be interested to see the real figures.

The M5 will offer less MPG but will give you a better bang for your buck with the M button pressed. The M3 is a faster car on many roads and better around town, but for sheer grunt V10 wins.

The questions are how important is size, the M5 is quite a big car compared to your Porsche and do you need the boot capacity. Any trackday requirements and do toys count?

M3 vs M5, better long distance mileage, the M5 has a rubbish 70 or 75 L tank and is annoying when doing big trips. M3 is nimble in town, seriously quick around the lanes and fast enough on most roads to keep you happy, but the M5 is the current Daddy of big saloons....although don't write off the new Jag....a great car and well worth a serious look, I kid you not!

Around town the M6 was c.14mpg... 24mpg on a run if you were VERY careful and VERY sensible....

Are you a gay homosexual?

I get 7 mpg around town in the M5 and never more than 20 mpg on a run

My E92 M3 has averaged 22MPG, which I think is excellent - fair amount of motorway driving but I haven't been driving slowly or anything - good mixture of utterly caning it and just going to the station, shops etc.

I'd imagine M5 would be a lot worse for fuel consumption. I considered an M5 also but thought that M3 would be better for the small road near me - can't say I'm disappointed - M3 is awesome and bizarrely, you don't see that many. I've only seen about 5 E92 M3s in the past four months!

My average is 17mpg in the M5 which I think is quite good for a car this quick. If I want a bit of fun single figures the come into the equation but then again on the motorway with cruise set to 80 it will do 25mpg.

I came from a 911 also, the M5 is a much better car.

I came from a 911 into a M6. The M6 is doing an average of 13 mpg over the few weeks I've had it. That's sub 10mpg in town and closer to 20 mpg on a run. Well worth it though.

12mpg from a 911 Turbo? Wow, you must be absolutely caning it everywhere.

I've heard these things are capable of 25mpg without much effort...

my very mixed driving; v heavy central london stop/start plus some longer mway jaunts on a very irregular basis has resulted in 20-21MPG average from my E92 over 5,000 odd miles.

Having had a 996 and worked for BMW, spending decent amounts of time in M5 and M6 I would say that the E92 might average 4-5mpg more...but drive both with a heavy foot and I think you'd find they're within 2 mpg of each other.

You average 12mpg in your Turbo, do you get it out of first? In mine going around SPA at circa 2.45 I average 8mpg, and 26mpg getting there..... The M5 however has averaged 18 over the last 2000, but on its trip to Hull yesterday it didn't use a drop, the recovery truck probably did though. Why did they have to use such a sh**e gear box?

20mpg from my M3 saloon over 3,000 miles - living in Surrey - about two thirds back roads, commute to station and the rest motorway driving.

Steady motorway cruise gives decent range as well.

Were you traversing the A5 at 180 every day? The 911 is genuinely economical ime.

The M6 is prodigious ito thirst: Fill it up, drive 10 miles and the dial has swung left: in an old M5 you'd have covered 50+ miles before the same drop.

I can't see the M3 being so bad.

Zod, what in the name of Hades are you doing? I get 14 mpg.

London traffic in the mornings - lots of first and second gear at 0-30 mph. frown

Gearbox and clutch do not appear to be on talking terms.
Will advise when BMW Hull work it out........
