2.0T FSI Engine??

86JR · 29 Dec 2009 at 10:55

I get around 42mpg average at the moment according to the computers (which do lie) at around 65 average, no overtaking.

last night i drove flat out and got 9mpg at around 90 average.

so i highly doubt 47mpg av

9mpg from a Passat diesel?

NickXX got twice that from a 330d around the Nurburgring. Just HOW hard were you driving!?

No manufacturer could get away with claiming 47 if it only did 30-35 real world, they are consistently 10% out, but rarely much more than that.

Are you joking?

like i said, flat out, i put chemical brothers - out of control on, and i got home from bodmin (i live near dobwalls) before the song finished.

that said it was 11pm and no traffic on the road.

WOW OMG UR SO COOL

but seriously, how slow is your car so that you need to mash the pedal to get 90mph average?

86JR · 29 Dec 2009 at 11:52

very slow, after all it does only have around 90hp at the moment, due to a big hole in the manifold.

Are you telling me BMW submitted a 30,000 mile car for testing?

Even if engines to 'loosen up' its still unacceptable. Pay £25k for a brand new 320d, get crap economy. Buy it 3 years later with 40k on it for half the price and get better economy

What did you get out of the 118D? I had one for 5 days with 2500miles on it and it averaged 48mpg.

It must be ridiculously slow because he must have just driven at wide open throttle the entire way. In even a half decent car doing that would probably cause a serious accident.

Best I got was 51mpg on a long distance run.

It shouldn't take 10,20k miles, in theory most will get progressively better after a couple of thousand miles up to 10k.

Obviously this depends on the car, engine and type of driving. A friends Micra was doing 35mpg ~ and when he bothered to take note again after about 5k he was hard pushed to get sub 40mpg.

90mph average is pretty serious, i take it youve never actually tried mjt, because 90mph average would be serious work indeed

90mph would be nearly vmax on a 90bhp passat

basically, it didnt happen.

i struggle to get as low as 9mpg average in my S4... just end the discussion there

Dangerous Dave · 29 Dec 2009 at 12:02

Another point to note is the 47mpg the OP has quoted is the extra urban figure for the 2L TFSI engine, the combined figure is 35mpg which most drivers get very close to. Even the 47mpg isn't too far fetched you can get 45mpg out of it sitting at a steady 50 in 6th however you are never going to be doing this for any length of time to get the average for a tank full into the 40s.

aproctor · 29 Dec 2009 at 12:02

On track days MX5s can go as low as 10mpg, this is an old car, engine etc and will do at best 35mpg.

Less in a passat derv...i think not.

I doubt he is, in my experience manufacturers figures are achieveable in the right circumstances. Most drivers accelerate too harshly, brake too late etc etc.

If you set out to achieve good MPG and have a decent trip computer that shows instantaneous/average MPG, you can drive the car to achieve it.

Sure you are going to have to go some to get it over a long period, as too many short journeys and hold ups have an impact, but the figures can be achieved, and in some cases, beaten.

Howard · 29 Dec 2009 at 12:08

You can get 35mpg out of your MX5?

In older cars, sure. I certainly didn't drive the 118d like I had just stolen it. I deliberately tried to be as efficient as possible. The 120d spent its entire 300 miles with me on the Motorway with the cruise set to 70mph as Muffin on here will testify. It still barely cracked 50mpg let alone the 67mpg its supposed to manage..

You'd be surprised, the 2.0 TDI is pretty good at returning decent economy even when driven hard.

A friend has a Golf 140 and averages close to 50mpg, dad has an A6 170 with a CVT gearbox and is averaging low 40s

No arguments regarding the 140 - said mate's Mrs has a Mk5 Golf with one in, as has my Dad. Maybe there's something strange about the installation in the Leon FR then?

To take a fuel consumption test, the car must have completed a minimum of 3000km's or the manufacturers run in period if longer, so yes you are right. It is quite possible that an vehicle submitted for a fuel consumption test may have done a lot more than 3000kms.

I usually find the best average fuel consumption on a diesel is around 8-10k miles, the low rpm they run at (comparitively) does mean an extended period of increased friction over a petrol.

i did north denmark - brussels in a day and averaged 80mph and i got slightly better consumption than 9mpg

cruisng at 150km/h the leon uses around 30-35mpg
add some autobahn vmax throttle mashing, roadworks and it still averaged in the 30s

But not 30-40k miles.
