EV mode button in C-HR is meant just for parkings or so (when you don't want to wake all neighborhood), when you're driving really slow and it handles just about a kilometer.ans said:If you are crawling on the m25 under 30 mph you could always push the EV button behind the hand brake and put it in electric mode
Not sure why you say that. EV mode can be used whenever you like and speed is slow. eg parking, manoevering, in traffic, in 20mph limit, setting off on short road (I live 200 yds from main road) etc. etc.Karmalakas said:EV mode button in C-HR is meant just for parkings or so (when you don't want to wake all neighborhood), when you're driving really slow and it handles just about a kilometer.ans said:If you are crawling on the m25 under 30 mph you could always push the EV button behind the hand brake and put it in electric mode
Now I know this may sound like a silly question but was one of your journeys uphill and the other downhill as that could influence the mpg? You really need to do the same journey with and without cc.MarkyMUK said:From the comments in this forum I tested the cruise control better economy theory over the weekend 185 miles of which 178 were Motorway with cruise on at 73 (70 according to my garmin satnav) = 48.9 mpg. Returning the following day I didn't use cruise and achieved over 56mpg. Same temperatures and did both journeys within the same time (5 mins more on return trip)
So for me cruise isn't more economical, by quite some margin.
David, yes you are correct, as I live by the sea but according to ordnance survey it is 9m above sea level, and the place I traveled to is 12 meters above, but as you know things aren't so linear since it's the places you travel through. That said 3m isn't going to make a difference and since the lanes on M5/M4/M25/M11 are just meters apart it (to my mind at least) wouldn't make a differencedavid63 said:Now I know this may sound like a silly question but was one of your journeys uphill and the other downhill as that could influence the mpg?

Some years ago I regularly drove from Lancashire to Hampshire (when the family lived there) and always I got better mpg on the journey down than on the journey back home. I should add that was in the days before I had cc.
