Official F80 M3 / F82 M4 EPA MPG gas mileage: 17/26 MPG

[tdizzle]

Isn't the initial EPA numbers just a guess and not an actual EPA test? Seems like I remember something similar happening on another car (maybe the F30?). Or I could be dreaming, but I swear I remember a year or so after launch the EPA actually tested the car and adjusted the numbers a bit.

I wonder (and I haven't done extensive research or even read every post in this thread because i'm lazy) if the car has been actually tested or is relying on some formula to estimate consumption and/or using what BMW is saying they expect.

These should be actual test numbers. They cannot release cars for sale until that is done.

'Vert gets same rating.

Meh, it happens. One engine failure doesn't make it a piece. I don't know of any high performance car that didn't have problems in the initial batch, including BMW's.

As for the M3, I think the econ is plenty good for a car of its size and power.

Jaguar F Type R with a 550hp V8 that goes 0 to 60 in 3.6s gets 16city,18combined, 23 hwy which is one less mpg than the M4 with DCT. Seems like BMW made awhole a lot of hoopla about efficiency/benefits of going turbo/smaller engine to get the same performance/efficiency as its V8 competition (even if its better than the old S65 V8)

The Jag has the 8 speed ZF. The 335i ZF auto give 3 mpg better than the 335i manual. The 8 speed in the M4 should give 20/29, way better than the Jag as it should. The "problem" in terms of mpg is not the engine it's the transmission. However a slush box in an M3 would not be ok even at 100 mpg...the DCT and manual are the best weapon it has vs. the Lexus and Benz competition.

I concur

Last Saturday I drove my new F80 using cruise control for hour, I was shock the computer says 30 miles/ gallon. I thought it a mistake and did reset it and got the same result.

With winter tires and the cold weather I managed a little over 23mpg on my first full tank. Not bad at all.

Not unusual. Drove from the PCD to Florida and averaged 30.8 mpg on 91 octane (which is what they put in during delivery). City driving is approximately 24 mpg.

I have been getting around 22mpg 'city' -- includes some stop sign, red light, parking garage crap -- 29 mpg highway -- includes a fair bit of 90+ mph cruising. Not quite as good as my N54, but the monster tires and 425 HP do exact a cost.

Put more air in your tires. Significant difference between the 30/30 psi that dealer puts in vs. the 34/36 that I prefer.

Our F80, #MSENTME, appears to be achieving ~22mpg ave.
Any highway driving using cruise control at 79mpg on turnpike yields 28.5mpg... Yes, display reads over 30mpg given conditions - just as it'll read 24mpg pulling a 'hill' and/or headwind.
Mixed driving = the car in stock trim has such limited traction, that it's not much 'fun' trying to really use too much of the throttle 'cause that lovely Yellow-flickering-light-of-promiscuity keeps intervening.
A fun-to-note techy observance is to use cruise while dash display reads TQ and HP figures on split screen with fuel mileage rates. Watching how little TQ and HP the car needs to achieve cruising speed is interesting.
Nice all around car for those questioning that fact. That said, if you know anyone looking for a #YMB #F80 for the right price, message me... Untimely life-changing factors on my part for you to take advantage of.

Sorry to hear. Stay strong.
