pandora21;599229 said:Bro Nightwind, yours a sports car. Vroom, Vroom......high FC worth it.
Mine raw, No mod.....only K&N filter dropped in recently. No roof, No M kit.
My info below:
My ride is e90 323i (2006 model)
FC is 15L/100km, or 6.6km/l. (a brand new E90 323i spec says 8.8km/l)
Mileage: 61,000km
Last oil change 1 mth ago.
17" Bridgestone (225/45)
My driving pattern : 70% "start/stop" city driving, only 30% highway.
Full tank 55 litres can only fetch me 370km.
Nightwind;611449 said:Hi for a fully "runned in" car your FC is rather high. Maybe you are heavy footed. My car has same engine as yours, and I put in 19" rims (versus your 17") and also a sun-roof and i also use paddleshift...and yet my FC is 14.1L per 100km
The FC sucks but its still better than your ride....i think u must be heavy footed la. Otherwise u better get the car checked out and tuned.
One interesting fact i note is that the FC on the 323i engine seems to be very bad compared to a 325i (same engine capacity but 325i has higher bhp at 218)....
I think the 323i needs high revs at low speeds (below 50km) and that kinda eats up alot of fuel. The car is ok when its on the go....but the lower bhp seems to affect the revs at lower speeeds.
I am conisdering a full engine remap ECU when the warranty period expires.....

However if my driving pattern changes to 20%C, 80%H, my FC can go up to 9-9.5km/L.
Hope the info is useful for ur comparison and Huat Ah!
Nightwind;611592 said:Ok thanks C3P0 i guess i was wrong....i had thought that with a detuned 2.5L engine the FC and performance of a 323i would be worse than a 325i. sounds like in terms of FC there is not much diff between the 2.
How old is your ride? Maybe the FC is so high coz engine is not runned in yet?

The engine is very fuel efficient when driving long distance on highway. But in start stop traffic, very bad.....
