    Fuel Economy Question

    I normally ride my DCT in manual mode

    However, when up to speed and cruising/motorways etc when no gear change is required, is there any fuel efficiency saving my riding in D mode?

    Christ, can't believe I'm posting this - next thing will be buying an anorak, noting train number and joining GreenPeace!

     :001: I've wondered this myself sometimes and concluded (based on nothing) that it doesn't make any difference. Once you're in top gear, economy will be the same irrespective of mode. The mode only changes the point at which gear changes happen. So I've decided to keep it in S mode like always.

    Hello,

    My pennyworth....

    I travel up to London every day on my 2016 DCT and achieve better economy in D mode at around 42mpg/9.5miles per litre on the trip computer. My journey is around 30 miles and comprises of about 18 miles of motorway/fast A road and the rest is mainly traffic filtering/slow running with short burst of acceleration.

    I have carried out my own testing on the economy in S mode and found it drops to about 37-38mpg/8.4miles per litre on the trip computer as it (seems to) hang onto the gears longer on the same journey.  Also Personally I find it harder to behave when in S mode! :001: When in D mode I ride some would say more sensibly!

    I think the damage to the mpg in sport mode is done when in traffic.

    I try to keep it at around 9.2 miles per litre as this gives me at least 3 round trips per tankful with a little to spare. Just my observations which I thought I would share.

    Best regards,

    David :028:

    Hi all.
    I am thinking of changing my manual CT to a dct I am a bit surprised
    By your miles per Ltr as auto should be better on fuel on the open road as info
    M reds is 55 per bar at 80 mph on the clock it's seems I would end with less miles
    per tank mine is 190 ish on main tank but have to ask do you use shell
    Supper unleaded even around town it's about 45 miles per bar and around town
    It's 160 miles on main tank some to think about achieving less miles per tank.

    Regards

    Which is.......?

    I'd get 55 mpg with a modification - its called losing 3 stone!

    I did a little test over the weekend ..........

    Wife (3rd brake) onboard - welsh rural twisties - reasonably sensible pace

    Achieved 205 miles to the full tank - with dash showing 15 miles left

    Quite impressed with that for a big thirsty V4 to be honest

    Thoughts?

    Extract from my write up on our Harz trip;

    This is my second CT, the first being a manual, whos first trip was to this very place.
    As with the first one, I think the Harz is made for the CT, it just seems to suit the bike perfectly. The big Honda easily eats the miles getting there, cruising at the limit and carrying all our gear with ease. My last CT gave me the best MPG ever on the way back at 55.2 MPG, the new one managed 55.1.

    This is cruising 2 up with full luggage between 110 to 130 KHP, Hooning about ive seen 43 :007:

    Fuelly thing below shows the MPG for both bikes.
