So....yeah, I'll take the 8,400rpm V8 again, please.
I had the E92 M3 for 4 years, averaged around 14,5 litres/100 km. My F80 Comp averages 10,5 litres. Its a massive massive difference. 10.5 should be around 27 mpg. I drive exactly the same with both cars. 2 days ago we were having fun with my son for 3 hours, averaged 12.5 litres/100 km. Don't know how 19mpg is possible if not on full throttle all the time.

It’s all about driving style, off/low boost the S55 is less thirsty than the S65 but at mid to high boost it’s thirstier. For me the S55’s party trick for all it is giving up in terms of high rpm thrills and induction noise vs the S65 is it’s steep torque curve. That steepness require high psi and since it’s accessible at pretty much all rpms I tend to use it often, that’s why my consumption is WAY higher than yours.

E92 M3 has a pretty good highway fuel economy. Even if I spend most of the time 4,000rpm+, it will average about 8-10km/L whereas if I drive like a granny I could pull off around 13km/L.

It's all about driving style, off/low boost the S55 is less thirsty than the S65 but at mid to high boost it's thirstier.

I track boost via AWRON when I drive my car, and during normal driving the S55 uses little to no boost at all. It's only during hard acceleration where it comes on heavy. The pic below was taken on the 241 toll roads in Orange County at about 70 MPH cruising speed (...actually I slowed down to 47 MPH to take the pic, but at 70 MPH on cruise control the boost was identical). I'm using 0 boost. It truly surprises me that your mileage is so bad.

Exactly. Stay off boost and your mpg gets good. I chose not to since to me it’s the always accessible TQ spike that makes the S55 and that require boost, a lot of it. For the S65 it’s obviously the high rpm glory, which is only accessible, well at high rpm . Average it all out, a lot of S55 TQ/boost vs less frequent high rpm S65 and I end up with very similar average mpg.

Got it!


P.S. The S55's induction noise in sport+ is really nice.

This makes sense. Its not like the S55 is some puny 1.2L 4 banger haha. It being a 3.0L I6 lends it to having plenty of naturally occurring low end torque. Even under moderate driving, all modern 3.xL NA BMW engines were capable of getting 28-32mpgs on the fwy. I would think the boost in the S55 only needs to come on during hard acceleration, i.e. flooring it

And yes, that turbo spooling in Sport+ is fun to listen to. What psi are you seeing on the Awron under WOT in the different modes? Have you tried to see what the differences in boost/tuning in Efficient vs. Sport vs. Sport+. I'm curious to see if the boost is stepped or capped between the different modes or if it just comes on sooner or later.

The boost comes on sooner, but I'll check this week and report back regarding boost at certain speeds. I'll do trial runs up to 100mph.

Hopefully not on public roads! Wouldn't want to get a ticket. ;-)

This being the first time the M3 will get an old engine ( ~2 years on the street at G8X launch. ) I suspect it will have some nice upgrades and retune for the M3 launch and that the X3M will receive those as well.

However I suspect sound could be more muted than today’s S58 due to EU regulations that apparently have already tamed the raucous of the M5C’s exhaust for the 2020 model year.

SO BMW isn’t fixing that with artificial sound pumped into the cabin over the stereo anymore?

I’m hoping aftermarket exhaust can make up for the EU regulation damping?

If only BMW would let owners adjust/select how much sound they want to hear in the cabin (sound levels is selectable via coding but what a PITA) then people wouldn't mind so much. I like having a low amount of the ASD but everyone's hearing is different so why not let it be a volume switch? BMW always thinks they know best but sometimes they should let people decide for themselves. Ever since the E60 M5 was roasted by Jeremy Clarkson for having too many user selectable modes it seems like BMW pulled back and made things overly simplified. Not good either...

Overly simplified? Have you seen how many customizations there are on modern M cars? The E60 was just the start, a new M8 can configure drivetrain, powertrain, traction, transmission, brakes, suspension, steering, etc. Too many if you ask me.

Believe it or not, average M owner need to hear good and artificial exhaust note without having to think about if it's artificial. Providing a volume switch reminds them it's fake and decrease the happiness. Would your life be better with a magical switch that can take off your wife/girlfriend's makeup at your will?

If you care enough to dislike it, just code it off. It's an one off thing, no need to complain.

S65 could average those low numbers if you were driving 70-80 km/h so with socks on. That is not easy anywhere. With full tank I got sometimes to 500km but normally around 450. The tank in the F80 is clearly smaller and I can easily reach 600km. Massive difference.
Dont trust the E92 boardcomputer. It showed much too positive mileage for me. The only right way was to divide tanked litres by driven kilometres. The F80 is spot on always.

Question

Would Euro markets be getting quite exhaust than US/ other markets due to the particulate filter?
