High speed limits and limited traffic. Highest I ever got was 30 mpg in the 3.0T. Cruising gets really good mileage. I have a lot of lights on the way to work so I usually hang out around 18-22 mph. My lifetime average is creeping up now that it's not 1000 degrees out but it's still right around 22 mpg.

I step on the gas and I really stop caring quickly. The toll roads around here are 75 (as high as 80 or 85 in some places). I get surprisingly great fuel economy at 70 mph.

Similar to the C

ECO: Really sluggish throttle response & early shifting
Comfort: Default. Decent for DD duty
Sport: Heavier steering, better throttle response
Sport+: Same as sport with sharper throttle response & exhaust burp on upshift. Doesn't go over 5th gear on the highway.
Individual: Combinations of the above, but not the exhaust burps (Sport+ only).

With these cars even cruising at 90 will result in good MPG... I can average about 28-30 mpg on the way back from Vegas, doing between 80-100mph with average about 90mph (3am in the morning).

The moment i get off the freeway, it goes back to teens :rofl:

The virtual cockpit defaults to a view that shows fuel economy. I know it's not a big deal one way or another, but I hate looking at it. Straight to map view.

Or, you can put it in what I call "mega cuck view" with the giant S dial

That's just the S Virtual Cuckpit. You activate mega cuck view by folding down the driver's visor and flipping up the mirror cover.

:spit:

Truer words have never been spoken!! LOL

Yeah the MPG's you can get is incredible when the conditions are right. I took a trip over the summer and on the way back I was able to drive for close to 3 hours with little to no traffic and here was my MPG.. I had my wife take the pic because even I couldn't believe it. And you're right as soon as I hit traffic and more city driving the MPG's dropped to 18 to 20..

Now granted, we all know that the trip computer isn't the most accurate way to calculate MPG's. But even if it's off, and I only got 27 or 28 MPG's how could I complain. This is a 5,000lbs suv with 2 adults and the cargo area packed..

This was in the V, right?

LOL Imagine...As you know it's very difficult to keep your foot out of it in that car..

difficult, yes...but even if you do, I personally never experienced a drastic enough improvement in mileage to warrant driving like a grandma...best was like 16.5mpg while coasting around 65mph

I think it all depends on the gearing... doesnt Corvette get something like 30mpg? due to its ridiculous long cuck.. i mean overdrive?

Hey its got a boost gauge, i wish i had that. mine only shows HP and Torque #s.
My Full digital gauge in comfort model, which i used 90% of the time looks exactly the same as the Analog one.. :rofl: so yah that is BMW for you.

I don't know about the science of it, but yeah it's like 15 city/30 highway.

1.5k rpm at 80mph.... that is how.

Mine is at 2k at 80mph...:what: considering how it was at 4.5rpm in my s2k before.

Dont you have the same ZF8 as me? so yours should be around the same.

:what:

I'm living in the stone age.

80mph = 3200RPM .... 16mpg :tomato: - 23mpg when lightly tuned.

:patriot:

No worries. Saintor is saving fuel, so you can use more.

No he's not. He's in Sport+ mode all the time to make the transmission bearable :rofl:

:chuckle:

:spit:

FFS. Saintor just needs to go out and buy his (his words) "krautmobile" and bail on this board.

He keeps on saying he is going to get the G20 3 series... i begged him not to. cuz he is the opposite of what BMW drivers are known for. We are known for many things.... But Saving fuel or MPG is not one of them.

It's all fun and games until he calls people names. :shrug:

That is weak sauce... name calling over the internet is weak shit.

Getting the dings out of my car next week. There were some when I bought it. Looking forward to it a little.

How many door dings do you have? it is only 1 year old right?

Son, that will be my 3rd BMW. You are a bit slow.

Or.

Possibly A6 2019. Maybe you can spot me in this video? (I was at this Audi event recently).

Yeah. I have three. All pre-existing. The guy that does it does it really affordably.

Interesting read. While to the avg laymen (like me and most other drivers and car culture consumers) it seems to make superficial sense (50,000 cycles vs 500,000?!), but I wonder if we are a bit arrogant to assume we know better than the thousands of engineers/minds who worked at all the various major OEMs to develop and put in place this system Presumably they've done the testing and the engineering/design so that it should last for a reasonable life of the motor?

This could be the perfect question for someone like Engineered Explained to tackle.

Remember that the rated life of a part or system does not at all mean that it's the expected life. They will add a liberal safety margin to that expected life and test to that. Our devices are expected to last 7 years, we test them to 21 years.

There's a ton of testing around this and while the issue of oil on bearings dripping off and causing wear is present, it still takes time to happen. Most cars don't actively pump oil through rod bearings, it splashes around and gets into those spots. When it does that it stays there until it drips off (which could take hours) so the start stop cars just have a timer to kick the engine back on to circulate oil. Either that or they have an electric oil pump that will splash the oil around to prevent issues. Also, modern oil is quite good at retaining a film over time. It's not like they just tossed in a better starter and crossed their fingers, there was a LOT of work that went into it.

I'm not at all worried about start/stop systems causing excess wear and leave it enabled all the time.

Since i am no engine expert, i cannot answer that with concrete evidence one way or the other.
But from Business point of view, why was this feature invented in the first place? I think it is safe to say that it is for EPA regulation compliance.
So Manuf.'s priority and intention were to be in compliance, at least on paper. Do you really think that the manuf. cares about how much gas you save per tank if they don't have to meet certain EPA requirements?

Let's say just say a component with 50,000 cycles would last 20 years... 500,000 cycles would last 10 years. We would never know because by that time, you would assume it is time to change it anyway due to normal wear and tear. Once a car is that old... there should not be any surprises when some things break down. Also within these 10 years, a lot of things like driving habit, gas, oil could affect the reliability of these components. That is why i said it would be difficult to relate any repairs back to this down the road.

Someone would really have to prove it to me that 50,000 cycles vs 500,000 cycles will have no effect on long term reliability, because it is just hard to believe. But as far as real world difference 10 or 15 years later, it is almost impossible to prove.

I just picked up an X3 loaner last night... interestingly the Auto Start/stop is on by default so every time i turn off the car, it comes back on :mad: My 3 and 4 series remembers the last setting.
With my 15 miles commute each way, the engine was turn off at least 20 times due to train, lights and traffic on the freeway. and that is 40 times a day round trip without going anywhere else.
Roughly, 150,000 times in 10 years. vs. less than 10,000 times under the same circumstances but without auto/start.

So only time will tell. But personally if i bought a car and intend to keep it for a LONG time, i would not take that risks for 1-2 mpg.. if even that.

I haven't followed the development that closely, but there are probably some high mileage start/stop vehicles out there. We'll see, I suppose.

The Prius has been start stop for a very long time. They go incredibly high in mileage without much issue from that system.

I may have mentioned previously...
but nobody listens to a rockstar. Especially a dumb one.

I saw this video, but this guy is an old fashion mechanic. He gets a car well. The problem is, he only recommends Toyota for perceived reliability and admits to being unable to fix German cars. Half his videos are "don't get this, get a Toyota"

This is what I would probably do if I owned a car with such feature.

Certainly true as only time will tell. But your other thoughts are valid as well...there would be impossible to tell in a single car in the real world as there will be so many variables that could've contributed to motor wear and tear. Until we get hard data from an engineer....some people will definitely be skeptical of this feature.

One interesting thought experiment with regards to your 1-2mpg comment, we can think of it as how much money that additional 1-2mpg may save over a very long time.
200k mi at 20mpg: 10000 gallons
200k mi at 21mpg: 9524 gallons - savings of 476 gallons ($1351 @ avg $2.84/gal)
200k mi at 22mpg: 9090 gallons - savings of 910 gallons ($2584 @ avg $2.84/gal)

Of course this would only be feasible if someone were to keep their car for a very long time and they'll have to calculate whether turning that feature off is worth the cost.

I thought they start with the battery, not gas. Most of them are silent when they first start moving.
