I would certainly take that on board, but then it only take a mili second to touch the brake to knock the CC off, one should still be alert regardless of whether using CC or no!
What would concern me more is having three punctures on presume-ing the m/way.

As Me says,cruise is far more accurate it will only give what is required instead of a lead boot.Quite right all EDC equipped engines deliever no fuel what so ever on a shut throttle on the overrun so although maybe yes downhill the set speed of say 60mph will be exceded the throttle will be shut.When the cruise parametre is enabled the engine output is increased,the idea is to save changing gear at hills and thus using fuel.(high engine speeds)Out of interest how can fuel be saved by gear usage as agaist cruise staying in one gear but ramping the torque up?
Nothing to do with caravans but I managed to drive 193 miles on cruise set to 73 mph (in a 70 speed limit) today without touching it, the brake or throttle.

Because the turbo needs to have a certain air mass flow to be in its most efficient range. Too low a crank speed can well result in poorer turbo efficiency, hence lower overall efficiency, just as too high a crank speed will. The secret is to operate the turbo at its ideal mass flow.

Trucker,
Read Nicks post, he does not specify what he was using so I assume he is referring to an accurate speed measuring device, in which case he is openly admitting speeding.
If not then he should clarify his methodology to avoid confusion and the justifiable condemnation for breaking the law.
Perhaps we should ask Mr Clegg to get rid of speeding laws part of his plea to the nation!

i usually set my cruise control to 70mph, and get my head down for forty winks. whether it saves me fuel i don't know, but i wake up refreshed and ready to enjoy my weekend away.
The in-dash display said 73, the gps said between 69 & 71.
It wasn't in Europe & more vehicles passed me than I passed.

Not quite sure on the link between crankspeed and boost pressure(turbo effiency).Boost pressure is a direct result of the quantity of fuel in each cylinder.For example an increase of fuel will result in a larger burnt charge exiting through the exhaust side of the turbocharger,thus increasing turbocharger speed and increasing boost pressure.
With modern day electronic control fuel delivery pressure and fuel quantity can be "adjusted" thus "adjusting" boost to suit the operation at any crankspeed.
Also another factor to mention is chargecooler sizing and type(air to air,water to air) and its effiency of keeping the charge at a disired temp.
John, if nick sets his CC to 73 that will be the car set to 73, unless the sat nav has CC, so I didnt have to assume that it was the speedo, as it says so in his post

This thread is about CC so I'm not going to add anything beyond this post, but as Nick openly reported setting his speed to an indicated 73, without specifying if it was vehicle Speedo or otherwise, one has to assume he was boasting about doing 73 in a 70mph zone. With no other information provided he was admitting speeding.
Even later when he relates that it was the vehicle speedo reading, he goes onto say the gps was indicating between 69 and 71. 71 is still speeding.
In his defence he says that many other vehicles were still passing him. Try telling that to the judge!
There is no defence for speeding.
If you wish to pursue this further I suggest you open a new thread.

John L. I assume you have never exceeded the limit by any figure.
I wasn't boasting that I had exceeded the speed limit, I was boasting that I had driven for 193 miles at a steady speed on cruise.
Now someone say I should have taken a break after 2 hours & that really will justify my decission to leave the UK.

I dont see how you can tell which is most economical ,i use the M4 quite a lot to go from Swansea to Reading a distance of about 150 miles ,every journey brings in different situations ,but driving solo in my Ford Mondeo 130 TDCI estate i have had 64.4 MPG using a mixture of foot excceleration and the cars cc ,but i have only acheived this once ,every journey i get a different reading ,but i do know if i go over 65 MPH the fuel economy will drop
