MPG at 150mph

[Wolverine]

Anyone know what mpg you would be doing at 150mph ?

[Scotty]

I don't know the RS6 but you can see the mpg INCREASE on my S4 as it gets faster. Nearly twice as efficient at 160 as accelaraing at 80mph : HERE

And the police notices on the motorways say reduce your speed and safe fuel wotaloadabollockseh?

[DrB]

In my old S4 it was 20mpg at 150mph.

[rs666]

Not the same, but I get about 5-7mpg when on track

[Wacko]

If it helps, I was getting 7 mpg with my foot to the metal (i.e accelerating not constant speed) @ 170mph in Germany last year!

So, when your fuel gauge says nada and your arse is twitching is it better to drive at 150mph and get to the petrol station quicker??!!

Apparrently so. Without condoning excessive speed in anyway shape or form our limited evidence, experience and trials would suggest contrary to popular held belief that driving in such a manner (constant high speeds) would indeed have a positive effect on fuel consumption. Cant quite get my head round it tbh.
