With a bit of cruise control driving to/from Wiseman's Ferry, I managed to improve my fuel economy considerably. The one thing I noticed today when driving was the moment you need to accelerate on a hill, the instant fuel consumption shoots to >20L/100km and that's shocking considering I'm only lightly throttling as opposed to heavy acceleration.

Image

However the thing which really saved fuel consumption was when I was coasting and it dropped to nil. And using cruise control, it hovered around the 10L/100km mark.

I guess I'll wait and see how things go once the car is more run in (it's currently on around 600km).

Jace,

I gotta say fuel consumption is not one of the strengths of either the Ralliart or Evo series. They are both heavy drinkers that I never have much faith in unfortunately.

With my ralliart, its exactly the same thing. Turn on the ignition and push down the accelerator gently, it starts with around 75L/100 and slowly works its way down. Uphill 20L/100k is also quite normal cos you are burying your right foot in 6th gear, otherwise if you downshift to 5th, its even worse, theres no other ways around it, but when you are cruising downhill, thats right its normally 0L/100K :lol:

Also, i wouldnt hold my hopes to high, even after the car ran in (I was hoping the fule consumption could be considerably more gentle and it never did!!), these days, if I'm driving like a grandma around, i'd be lucky to get 10.7L/100K with 65% cruising around and 35% heavy trafic, which is prolly acceptable i guess, if i get carried away from time to time, my worst record was 13.5L/100K -- 370Km full tank with the tank completely empty, you do the maths.

Another thing that really annoys me is that it seems to take forever for the fuel consumption to go down and the moment you downshift and reving this thing up, it jumps instantly up by .5Litre at least, so I really can't be bothered sometime, i mean if you can afford a $50,000 car ($70,000 in your case JACE :roll: ) who cares about a few extra litres, let her drink if it keeps her happy.

No kidding, trying to go faster up a hill will give you worse fuel economy.. Instead of cruising up it and dropping a bit of speed and staying at a constant power output you're asking the car to put more effort into going up a hill faster. Obviously it's going to drink more fuel

Fuel consumption is directly linked to your right foot, this has never been a huge secret.

ive had it up to 98L/100km before but this was the other day.
My true average in around town cruising is around 7L/100km.
My best tank was 702kms and worst was 542kms.
I have a 2.0 N/A too =P

LOL thanks for the responses guys- the point I was trying to make is that in say, my Civic, when going up the hill, I am pretty sure the fuel consumption was nowhere near what the Evo is doing when climbing. I'm not burying the foot into the ground here- I'm barely maintaining my speed of 60-70km/h. It just surprises me that even on slight upwards inclines, the fuel consumption also jumps considerably. I suppose the instantaneous fuel consumption graph is a gift and a curse!

As for the issues with the MMCS reported elsewhere on ClubCJ (somewhere in the satnav/head unit forums), I got the distance to empty error today when my fuel dropped to below 50km to go;

Image

I managed to average out a 13-14L day with mostly highway cruising. The interesting thing I noted is that even when I go a bit hard and overtake here and there, etc... the fuel consumption level doesn't change dramatically and stays around the 13-14L mark. Is it like this for RA owners too whereby thrashing or cruising doesn't make much difference?

7L/100km is awesome! When I drive short distances my average is around 9-10L/100km and if there are no hills maybe somewhere in the 8's but never 7L/100km. I can only get 7L/100km cruising

Thought I'd add that with civilised driving of decent distances >10km at a time, I'm averaging around 12.8L/100km which is inclusive of urban commuting around the place but without significant traffic (i.e. always moving).

New personal best of 10.9L/100km for fuel economy driving around 8pm on Victoria Rd:

Please don't- it's more of an Evo fuel diary although I guess if you really want to, it's the mods call :) Also makes the Evo X board a bit fuller with more topics!
