Cheers Scotty, all I really bother doing is get into 5th as soon as I can and trundle up to junctions in 1st rather than neutral after Clarkson said it was more fuel efficient.
Does anyone know the physics of this? Is fuel consumption directly proportional to weight as per my rigorous and complex mathematical modelling?
There may be something in it, but the ammounts could be very very small yearly- so it would take a while to claim the money back.
You need to keep in mind as well that clarkson was comenting on all Modern cars at that point (so that would be cars from 03 onwards i expect- He was in a 03 plate Audi A8 TDI)
There may be a little truth that a pumas engine would use less fuel coasting in gear, then ideling with the clutch in- but again the ammounts your talking about are so miniscule that the savings over the year prob wouldn't even pay for a alitre of petrol.
I could be completly wrong, but thats how i would veiw.
Oh and as for getting into 5th gear as quick as possiable- Remeber the engine is at its most efficent when all the fluids have warmed up- and the 1700 engine is only pulling 1500-2000 rpm at 30. Also being in the lowest gear is not always the most econmical why to drive- if the engine is constantly underload to maintain the speed it will use more fuel.
I would suggest doing the free(ish) simple things i said before and see if that helps.
Also something that you may need to do could be a new Hego sensor if your fuel econmy is poor
Mine has knackerd up abit(ok alot) hence the really bad fuel econemy.
A new one should be around £65 from your local Motorfactors (Or £135 from ford)
Cheers Flash- I'll double check later and drop the wheel to make sure- but the rim does look sliver not black?
