How's your fuel economy?

Back to mpg, I'm thoroughly impressed with these numbers. It's similar to what I was getting in my previous 335xi, but with 125+ hp/tq.

Based on your username, you probably picked that up on S2000 boards. It's absolutely true on that car because the synchros on that Aisin transmission are built only to accept the loads from neighboring gears. For example, the RPM drop from 5th to 6th is small, so 6th only has a tiny synchro. This is normally fine, but people commonly run it to redline in 1st and 2nd then realize that they're loud and breaking the speed limit, so they shift directly into 6th. Coincidentally, lots of S2000s have issues with dead 6th gear synchros. If you want to quickly get into 6th on that car, the solution is to clutch in, row through all the intermediate gears, and then clutch out.

It's a blessing and a curse; the S2000's MT is one of the best feeling manual transmissions out there because of this, but it's also very fragile if not driven properly. This isn't an issue on other cars. In fact, a lot of MT cars will lock you out of 2nd and 3rd when you're in economy mode and force you to shift directly into 4th to save fuel.

Are you a wizard?? Yea, I'm pretty sure I read that on s2ki like you said. I do miss the transmission on the s2k but after getting used to the 6mt on the M3, I prefer this one over the s2000. However, I miss the s2000 every day since I've sold it....great car.

I have a s2000 and im taking delivery of my M4 on sat. ill see how they differ in shifting impressions

yea I love my tranny in my s2k. in my opinion, the 5th gear is useless for me. I hardly ever cruise on 5th whether in local or in freeway unless im travelling in that exact speed where 5th gear is adequate.

LMAO that was a great bit of deductive reasoning if I do say so myself!

[darmstadt]

Only done 1100km so far but as work is a 300km commute on the autobahn twice weekly (in efficiency but speeds of around 100-120 mph) and the rest is town (in sport mode naturally), then the indicated 22mpg (US) or 10,5 l/100km is pretty good I think

[pr0gi]

10,5 l/100km is pretty impressive if you ask me! My X5 3.0sd had 10-11l/100km

[major one]

first full tank of petrol - 18.6mpg. mix of easy and spirited driving - both on surface roads and motorways.

[superrobo]

gone through 3 tanks of gas, average 20.5 mpg
on freeway, that's about 23 mpg @ 70 to 80 mph

[irablumberg]

Mixed highway and suburban driving, spirited, has yielded about 20.8 MPG overall over the last 1,500 miles. Sport+ engine mode, Sport mode for DCT.

[GOLFFRR]

im avg 22.7 in the city so far.

[MaynardZed]

In at 19.2 mpg total. It was at 10.2mpg when I picked it up from idling, moving around vpc etc. Have not been babying the car either.

I'm modestly impressed so far, I think it could do 25+ mpg on the highway easily.

[Wes Howell]

I'm getting 14. lol.

Unfortunately, the rubber is going to be more expensive than gas.

[DadzM4]

If I reset when I am on the highway I can easily get 20+ doing 90 average. If I look after a day or two of driving normal for me, which is aggressive and fast I am at around 16 but that is with only 300+ miles on the car so I am certain it will pick up another 2-3 mpg as it breaks in. My E92 I averaged about 12 once fully broken in, so a large % better then the old.

[TurboSid]

20-22mpg

[04RC51]

I get 26mpg (in efficient) on the highway and my normal driving (all in sport plus) is around 15.5mph.

[robertg]

20.5 in city driving.

M1 set to Comfort Sport Sport

M2 set to Sport Plus Sport Plus Sport Plus

Car has 615 miles on it.

[jc05e46m3]

20-23

[E92LNGCGY]

11.9L per 100km about 19.8 mpg US. 90% city driving. Usually in M1 setting sport, sport, sport plus with start stop disabled.

[joeyb26]

18-20 in mainly city, i've seen has high as 28mpg on an 90 mile highway drive

[SakhirM4]

Run two tanks so far and getting 22.4 combined city/highway with under 1200 mile restrictions. My E46 only got 18 - 19 in same conditions.

[dhoggm3]

925 miles. 20.2 MPG during break-in.
