[B]E90 325i Fuel Consumption Figures[/B]

[Juan Powerblow]

That's interesting. I'm doing 13.3 L/100kms on the back of an average speed of 36.4 km/h. Unlike the E46, my E92 seems unwilling to glide so much which can be frustrating when trying to preserve FC. I suppose the added safety of engine braking is more important to BMW. Being a 323i, I do have to use a bit more revs but yet again, as E46F has also observed, my transmission feels quite different from his.

Ok we're getting some interesting results here:

E46F 325i: 14.7ltr/100km avg speed 28km/h
JPB 323i: 13.3ltr/100km avg speed 36.4km/h




Lets see if we can see some patterns here. Would be interested to see David Yong's and Cobra Kai's details as well

 

[Juan Powerblow]

Yeah, let's get more feedback!

I've only just reset my OBC so figures not accurate yet but will put mine up in a few days..

Looking at the figures posted already tho there seems to be some large variables in FC..are all the readings the same ltr/100km and not km/ltr or is that just the 4pots vs. the 6pots?

I put on lots of highway miles. So its quite easy to see why im getting a better fuel efficiency and speed avg. Traffic from PJ - Port Klang is a minimal.

Will be interesting to see what Cobra gets, since he runs highway & city everyday.

 

[Juan Powerblow]

There's already a strong and obvious co-relation between FC and average speeds. Good on E46F to initiate this fact finding mission. As for David Yong being out of the norm, this could just well be due to his "brand new" engine needing to run-in more. It would be helpful to get more feedback.

 

[danc]

The only thing to note is, if you reset the FC I don't think it resets the avg miles. So if you reset one and not both, the correlation might still be out.

 

[David Yong]

Hmm..... it seems like the faster you drive, the better FC you will get. Strange lar....

No wonder our friend Rimsukan driving on DS mode most of the time and still achieve better FC than us on normal D.

 

[E46Fanatic]

From the little survey, it looks like DY and myself are the slow poke drivers.... Amazing that some of you guys get so high average speeds!!

Heheh... y'all pamper your cars too much leh. Must rev above 2,500 rpms every now and then lor... :smokin:

 

[danc]

Guys,

It's the avg speed, so it actually means more of hiway crusing versus jam that gives the better FC. Driving fast in a stop ang go situation I doubt will improve on FC

 

[David Yong]

Most of the time my driving is town driving. Not much of highway driving. So that is why my average speed is not high. I think the highest average that I have achieved before is also less than 50km/h.

 

[Cobra Kai]

Guys,

My numbers below. This is the average over 4 months of daily driving and almost 10,000 km. For my daily trips to and from work, I actually track individually using the trip monitor. It's about 43 km for me each way, and the FC varies from about 10.5 ltr/100km - 15.5 ltr/100km depending on traffic conditions.

The 10.5 reading generally comes with average traffic (45 - 55 minutes) with average speed between 40 km/h - 60 km/h, which means that I am always moving, but too much traffic to really let loose

With really empty roads, I can average 100km/h per trip (26-28 minutes), and FC is about 11.5 - 12 ltr/100km. The FC only starts climbing on uphill acceleration or 180 km/h+.

The highest FC readings, i.e. 12+ is always when I am stuck in KL traffic, and average speed for the trip is < 40 km/h.

My average FC hasn't actually changed much over 4 months. Started off around 11.5, then went down to 11.4 after a trip to Melaka, and now stabilised around 11.6 for last couple of months. I'm interested to see the impact after the 10K mark as suggested by danc.

CK, yours is quite similar with danc's reading.
