What fuel economy do you get?

[Ray-Vic]

Having got our Boxer 2.0L BlueHDi based Bailey in March, and having had the engine remapped from 160bhp to 210bhp, I was interested to see what I get in terms of MPG. I reset trip B and we have been on a couple of trips away totalling just over 450 miles. I generally stick to the speed limits and tend to travel at 60mph on motorways on cruise control, with the odd stint above this if needing to for overtaking.

We are currently rated at 3,850kg and generally run very close to this (we were over last time out so have been a lot more diligent with loading)!

I checked the average MPG tonight when returning from Glastonbury and it is 29.0mpg, which I am not unhappy with at all. However, it got me thinking about whether it is reasonable, or not so good compared to other motorhomes, and what do you guys here return, obviously with consideration given to your particular driving style.

Many thanks.

see my previous posts regarding this.

I posted our last four motorhome MPG's on it.

210 bhp from a 2 litre diesel sounds very ambitious to me ?

fiat 2.3l multijet , mapped to 180bhp, stick to speed limits as best i can but on motorways were possible i use cruise control at (true , not speedo) 69mph.

average 28.6mpg calculated, 28.8mpg on the dashboard data.

Very subjective, due to type of vehicle such as A class, tag axle, engine (size and power) weight, also type or roads, such as up here in the Highlands it's very hilly so I would say lower mpg as against say Lincolnshire which is flat.

Our Hymer B544 (4250kg) has been remapped from 130 to 150 and returns an average 25mpg. Personally we don't worry about MPG.

How many ltrs do you think F1 cars are then?

Not really comparable though to a mass produced diesel lump

130BHP to 180BHP remap on my Citroen 2Ltr and on on this last trip around the West coast of Scotland including all the stop start single track roads still got 34MPG. Normal driving I have got it up to 40MPG

2.8JTD PVC .. used as a daily driver.. I log on Fuelly

that is the average over a year..

Agreed but as the girls say ‘size doesn’t matter’

 

[The Wino]

Has anyone actually taken a MH to a rolling road before and after remapping to actually measure the difference? I bet not many get the promised increase

 

[BusyBuilder]

My BMW K1300 regularly gets 48mpg around the Highlands, but unfortunately only has 165bhp.

 

[Nirvanauk]

I haven't a clue and I don't think it would make any difference if it was doing 30 or 29. It wouldn't stop my hobby.

 

[Stoosal]

Ford Transit 2.0 170bhp….driving style same as you. 28-30mpg

My 200 BHP GSXR1000 does 50 ish going steady.
Dropped to 26 at Portimao a couple of weeks ago

No idea, this is the figure which Superchips provide for their performance configuration (they do different maps). Whether it makes that I don't know, I haven't had it on a Dyno, but the difference from before to after is significant.

Nearly enough to get up to the speed limit

 

[Carpmart]

Iveco 3.0 hauling a 7.3T dirty great big RS body around returns high teens… seems decent to me!

The 1litre audi q2 has 116bhp & the 1,5 litre in some forms gets to high 200's so anything is possible?

Renault master 2.5, havnt got a clue what hp but it will cruise all day at 70 and clocks 34 mpg regular as clockwork , 80 on motorways or tootleing around country lanes.

It won't stop mine either, I just wondered what others got and whether I was in the ballpark of where others are. I've driven a Tesla for the last 4 years (and a motorbike) so have no idea what is good, bad or indifferent for a diesel motorhome.

 

[gus-lopez]

I average 33 mpg travelling back & forwards to the uk with a roof box on & fully loaded. This is using N&D roads stopping & starting, roundabouts etc. No box & dual carriageways I have seen 39/40 . That is on a 2,2tdci Transit fwdrive PVC.
I'd be happy with 29/30 on a large coachbuilt like your Bailey.My last coachbuilt,,extremely under powered, would average 30mpg.

when mine was done it was on the rolling road, but the original 130bhp and the remapped bhp are calculated at the flywheel.

however, i was not interested in the bhp increase but the increase in torque it gave me. which, makes a huge difference and is very noticeable.

 

[Ray-Vic]

Thanks for the replies all, I think it looks generally like high 20's is pretty much average. That's good, I'm quite happy to be getting that.

We're only on our 4th tank of fuel so can't "really" do a long term average on our 160hp peugeot Bailye, but ours is lighter (3250kg on weighbridge with us, dog, clothes, food and water). We seem to get based on my calucations 28-32mpg depending on driving style -> obviously more on the sites which are mostly motorways (ie, A14, M6) to get to, less on suffolks windy A roads which are more direct and we got the highest mpg when we were doing a cross country delivery from dealer to home (250 mi) all at ~ 65mph.. I'd be tempted for the remap if we had more payload, but frankly we don't so with us pulling half a ton less than you it's not needed in our case.

I only really did it as we were always going to increase the load to 4,000kg (Lady V likes to carry 500kg of wine!!) and I just felt that I would like a little more oomph on motorways and hills etc, resulting in less gear changing, which I have definitely got. It's made such a difference to driving (as noted above, it's more the increase in torque which is noticeable) and well worth the £250 for me. I think with the lower weight the 160hp is more than enough and when I picked it up and drove it home empty I was suitably impressed with the power it had.

Fiat based A Class, 140hbp 9 G auto, 7,000 miles on the clock, average to date 28.6mpg.

Yeah, I can see that but on our trip (eventually back) from France next year, we'll just dump the water for wine at close to the border on way home. 100kg of water is a lot of wine, and we have 250-300kg spare without doing that, so we have 400kg of wine available !
