Is using cruise control economic?

<< < (2/2)

waveydavey:
It depends how you use it and how you drive:
Any automatic system can't see what is happening ahead so it can only react rather than predict, if you drive 100% all the time you will do better. You can anticipate changes in speed and preempt them slowly.

That said the cruise control doesn't make mistakes or forget. If you are on cruise and start going down a  hill it will back off whereas most people tend to pick up speed - that will save fuel and more to the point your licence.

Overall the general answer is yes only because it is so constant and even the best drivers cant put that level of attention all the time.

Also as has been said the benefits for your back etc. are tremendous - not having one side muscles in tension for hours.

Me - I am a total convert, when i didn't have one in the old Disco I fitted it myself.

You want economy ???

Sell your Land Rovers !!!

cruise control will never beat a good driver who is thinking fuel consumption. proved it time and time again with the trucks at work.

cruise control tries to maintain a set speed uphill, when for fuel econonmy a driver would allow the vehicle to slow.
it accerates quickly, too quickly for good fuel mpg. Some Volvos accererate quicker with cruise than with the throttle.

I'm with Davidlandy.  It's great on flat roads with no traffic, but it won't drive as economically as a decent driver when you take hills and traffic into account.

The TD5 cruise DOES accelerate quite hard - but you can combat this by not using the Reset button.  When you have to slow down, don't use the Cruise to reach normal speed again;  accelerate manually up to the speed you want and then hit the + button again to maintain the speed.
