A Very Unscientific Experiment

[Obadiah]

Thought you might like some observations on the new 1.2TSi engine, which is supposed to be greener.

 

Just repeated a drive round the M25 in my Yeti with the new engine, that I did in the wifes 'old' one.

 

'Old' engine cruising at 70mph max managed just about 43mpg

'New' engine managed almost 47mpg

 

Seems it might just be true!!

Seems strange - perhaps the wind changed favourably for your 2nd run? I find it difficult to believe they get 10% more economy out of it without major changes? Is it re-engineered?

[Urrell]

It probably has a raft of small changes and I think they now all come with regenerative braking etc.
Don't know how much of that the earlier versions had.

That's a great improvement. There are a few differences in the engine i.e. the new one is a 16 valve cambelt engine with the turbo on the back (I think) the old one is a 8 valve cam chain engine with the turbo on the front

I know you did the same run but was the air temperature about the same? This makes a big difference.

Nevertheless 47MPG at a steady 70MPH is pretty good for a Yeti which is hardly the most aerodynamic vehicle! I assume the 47 was from the Maxidot readout so probably about 43 real MPG. Might be interesting to keep a fill-to-fill comparison between the 2 Yeti's for a few thousand miles to get a more accurate comparison.

^^^^at that speed I agree with the 43mpg guestimation .

[Spaldi01]

The display on my yeti 1.2 is only 3% optimistic. My old A3 2.0 TDI was 20% optimistic. Is the display in petrol cars more accurate?

Don't believe it - no one has ever cruised round Motorway 25 at 70mph!

Even I don't believe that!

He was probably following a Romanian HGV.

I can vouch that it can be done at 3 am when going to Gatwick airport

I once was driven along the part of the southern section of the M25, at around 7 at night at over 100mph..................................
