I get 400 miles, 40/60 city/highway, out of my lowly N52 with some pretty aggressive driving in manual mode... 600 even if its all highway miles.
The M is a beast but jeez pumping twice a week would just suck. Currently pump every 7-10 days.

No tunes at all, all engine parts are stock except for the RPI scoop which is really cosmetics. I have heard from many E60 owners around NYC that they too as well saw drop in fuel economy. I just recently got it serviced at BMW changed spark plugs, filters, and other maintenance and I still see the same results in city driving.

I might as well trade in the 535 for an M5 if that's what M5 owners are spending on gas. I'm really thinking about it too.

Holy crap, I get well over 400 miles to a tank (between 415-430). I spend around $200/mo on gas. Yes, I can squeeze out 600 miles a tank of ALL highway - made it from SoCal to Vegas on less than half a tank and it still said 292 miles to empty. I wouldn't mind doubling my gas bill to have an M5, it's a trade of WELL worth it.

All in all the mileage on BMW's is pretty impressive to me taking into consideration power and weight.
Who else can make 500hp at around 4000lbs and get better mileage?

DO IT! GO FOR IT!

my only complaint is the shitty ass SMG transmission. i wish it were the DCT or a regular 6 or 7 speed auto....the SMG just sucks. the only time i enjoy it is in ///M mode on the freeway....other than that its for the birds lol

You have a point there, my last car was the SRT-8 Jeep, I got a whopping 9 mpg in that thing!!!! It cost me around $750/mo in gas.

If the M5 is your only car, I think you may have a problem lol. Call me crazy while it is practical in many ways, I personally feel its very impractical. . . if for anything maintenance and fuel costs. I have a 2008 535i and I get a consistent 20 MPG out of it, on freeway trips I get nothing less than 24 MPG's. If you're getting 12-13 mpg out of a 535i, something is SERIOUSLY wrong. In the absolute worst city conditions I haven't seen less than 16.5 MPG. I also have a 2003 Nissan Maxima, I drive 64 miles for my daily commute. That car takes $57 to fill the tank and it lasts me all week or roughly 300 miles on a tank. B

Bimmers cost $$$ to maintain. M5 and fuel economy are irrelevant. I'm thinking of selling my 535i and picking up an LCI M5 (got too used to the nice LCI interior ) but I in no way will use the M5 as my daily car. I don't even use the 535i as my daily car just because of the costs of maintenance, I may be an exception though I like to keep my "nice" cars very nice

Long story short, do not buy an M5 if fuel is concern, worry more about brake and clutch jobs. A pair of rotors on the M5 run no less than $1000 ($2000 for a set of 4) A clutch job can cost upwards of $5000. It is a legit super car and a result has the respective maintenance costs.

Something is wrong with your car or how you drive. I get 400+ miles all the time on trips but 350 no problem around town. I don't idle in traffic much though and when I go we just go, not much in town light to light driving. computer mpg never really goes under 20.5 mpg.

The only time it really gets into the 18-19 mpg range is on local trips on 2 lane roads where I'm passing every car in 3rd gear.

I have the dinan stage 2 software and their exhaust and 64,000 miles. Oh, and have a Thule cargo box on all the time too.

Last year I spent over $10,000 on gas in a few vehicles on one credit card.... we drive a lot.

I'm getting 13mpg mixed driving, so go from there.
