mpg with cruise control - Page 2

andre372 · 30th May 2014, 11:51

Thanks everyone for sharing your experience. I always try to maintain speed when going uphill or around slight bends so this shouldn't be a factor. and as you say, cruise control makes small efficient adjustments rather than constantly going up and down by a few mph when relying on your right foot.
I guess I'll do a brim to brim test myself someday.

I thought that I get slightly better fuel consumption when using cruise control on long motorway runs but not checked brim to brim.

That's my hope as well

My V6 does the same sort of thing. If I deselect the cruise, (say to get safe separation from other traffic), when I press resume the car goes hell for leather, until it gets back up to the speed.

Driving manually, I would be much smoother with a gentler acceleration.

my mpg is better when using the control
I use mine all the time even down to 30 mph.

Cruise doesn't really work on UK motorways, you have to keep slowing down for the bends innit....

The bends are usually laid out for 70 MPH traffic...

I would not buy a car which did not have cruise fitted or one I could not fit it to due to driving 25-30k per year.
So I use it all the time and can't say I've noticed any difference in fuel consumption when using it.

Analogue or digital display?

I achieved my best mpg figure to date 60.3mpg with the cruise control set at 70 on an empty M5 between Gloucester and Exmouth.
