LCR and 345miles a tank

[metroarmadillo]

how many litres are you all putting in when filling up?
In my experience if you fill up fairly shortly after the warning light comes on its going to be 55 litres?

this is 12.1 gallons.
So 345 from a tank is a little over 28mpg.
450 is around 37mpg.

FYI based on 55 litres:

miles + mpg

300 = 24.793
310 = 25.620
320 = 26.446
330 = 27.273
340 = 28.099
350 = 28.926
360 = 29.752
370 = 30.579
380 = 31.405
390 = 32.231
400 = 33.058
410 = 33.884
420 = 34.711
430 = 35.537
440 = 36.364
450 = 37.190
460 = 38.017
470 = 38.843


I have to say usually people on SCN would be reporting 23-29 mpg with most id say getting around 27mpg on their LCRs.
Seems we have managed to find the few who are getting more than this. Although im one of them

I always put in as much as I can so its sometimes 55 litres or sometimes tiny bit more, usually just to work and back and some weekend driving I'm lucky to get 350 to a tank but on long runs I can quite comfortably get 38mpg 450 miles ish. Before I had my car mapped my average over quite a few months was 24mpg and since mapping its gone up to 28mpg and thats driving the same way

How are perpeople seeing these figures i get 18mpgs on short trips & 27 on long

 

[Klone]

i have worked my mpg and my trip is pretty close tbh.

average driving i get just over 350, long runs i can get way more but havent done a full tank run yet... only a 170mile round trip which was around 1/4 of a tank.

6th gear 70mph ftw

 

[h0tr0x]

most i have seen is 31mpg from my car and that included a lot of coasting! wtf?

stop coasting for a start, learn how to drive economically.

i usually get 350-400 to a tank.

stop coasting for a start, learn how to drive economically.

this is the key... coasting in neutral uses petrol, if you let off in gear and let the engine brake the fuel supply stops... i think thats right?

 

[Joeb]

fcuk that.

my journeys are all A-B, no motorway, not even a hint.

about 280 if i dont put my foot down
250 if i give it some beans

24mpg



wouldnt the above method of letting the engine slow the car ruin the clutch? eat away at it?

 

[MATTCR]

mine looks like an LCR but I get 650 to a tank... 55mpg......

TAXI..............

get out. Now.

Nope, engine braking is fine... as long as you dont try and change from 5th to 2nd to brake!

your looking at it wrong.
Its not about engine braking,

Instead look at it as keeping the engine turning over without having top use fuel.


If you pop it into neutral the engine will then bein ticking over in the same way as if you were stopped at the lights with the engine running.
In both cases the engine is using fuel to keep going, - to stop itself from stopping/stalling.

If you simply lift off the accelerator and allow the car to slow like this (leaving it in gear) then the turning of the wheels keeps the engine turning over (via the gearbox clearly). There is not need for fuel to keep the engine turning.

Forget about the clutch, it doesnt cause an issue (assuming you dont ram it into 2nd at 70mpg) but in this case the clutch is the last thing to worry about anyway.


The key to be able to take advantage of this is ANTICIPATION. try driving without ever having to brake. clearly DO BRAKE if you have to, but see how far you can get without using it. (and no changing down the gears to slow the car either).
It will surprise you how little throttle you actually need to use in and around towns.

Traffic lights ahead... are they red? have they just turned red? if so they are unlikely to change to green soon so ease off the accelerator as soon as you are aware and take advantage of fuel free mileage as you approach the lights. If you are lucky you can arrive just as the que moves and you dont need to stop, but instead seemlessly joint the traffic.

Bloody glad mines on LPG!
But I agree! On a run I was only getting 30 to35 mpg!

[matt bristol]

OMG, my cupra has only ever managed 350 miles on a tank full, usually its around 280 - 300. Oh did I buy the wrong car!!!!

 

[jclaydon]

I rarely get less than 320 per tank from normal use.

I managed to get from Peterborough to the Nurburgring on little more than a single tank too

mpg

nobodys mentioned it but i think having cruise control really helps and keeps you legal

 

[bendohhh]

damnnn, i very rarely get over 280 miles to a tank in mine. that's from the brim to the light coming on.

 

[Ape]

A full tank in mine (Stage 2) will return about 280miles, which I think is around 21mpg. Mine rarely gets used economically as it's my toy. I have got 38mpg in the past (on the way to the Nurburgring, 6th gear @ around 70 / 75mph). On the track, I average between 3.5 and 5.5mpg

 

[andycupra]

cruise control will likely help people that are inherently poor at driving economically, - its amazxing how many people seem unable to keep their foot still.
However, if you are good at economical driving and understand what gets the best results then ultimately you should be able to get better mpg than using cruise.

I will clarify at this point that if you drive on a straight flat piece of road at a constant speed then you cant beat cruise. However if there are gradients, bends, changes to speed, traffic, junctions etc etc then you should have the advantage.
Why?
Cruise is purely reactive. It constantly measures speed and responds when the speed alters.
You on the other hand can be PRO-active. ie you can ANTICIPATE. for example you can let the speed increase on a downhill section to help with the following uphill section and avoid heavy throttle.
