Thinking of changing our motorhome to an Autotrail Apache 634U. Only problem is it is a 3 litre automatic on a fiat decato, which we didnt want. Has anyone got any information on what we could expect mpg wise. Also, presume the tax will be dearer than our Autocruise stargazer 2.3.

I know its a daft question but if you don't want an automatic Fiat Ducato why by one .. :banana:
 
Only because it is the model we have been looking for. Love the layout, as it has a small garage accross back. First thoughts were to just forget it and keep on looking. But just wondered if someone on here might have some info.
 
We have a 2.8 JTD Autotrail Dakota on a Fiat Ducato and get around 25mpg. Not good but worth it for the layout you want. We got slightly more out of our older Kon Tiki but the layout just annoyed me on long trips. x
 
We are hanging the other way, trading in our Adria on a 2.5 Renault automatic for a Rapido A class on a Fiat 3.0 ltr manual. We have been looking for a Mercedes automatic but in the end decided to go with the manual Fiat (much cheaper).
No reason the tax should be any different apart from the weight, both our current & the new van are plated at 3850 kg so they are classed as PHGV £165. The fuel consumption we had with the auto was approx. 28 mpg, this was the average from new over 25k miles & it was starting to get more around the 30's. Hoping the new van will give at least around the 25 mpg but just have to watch the right foot.
 
We have the 3.0 manual on our autotrail Dakota and get about 25 to 26mpg. Not the best but I would never change for a smaller engine. It is great for hills and has bags of power ( try not to get too lead footed though) this is a 4.2 ton unit so the road tax is £165.00
 
Fuel

Hi Anglia
I have a Hymer B614 / 7mtr with / Fiat 2.8ltr. I am currently getting 27.7 mpg on a bad day at 75mph wind head on 23mpg.

Hope this helps :banana:

Thanks for all the help. Yep found out road tax will be cheaper and mpg isnt going to make much difference.

Hopefully going to see it this week.
 
MPG 2.8JTD Chip

Van, Knaus Sun Traveller, Fiat Ducato, manual 2.8 JTD, not exactly steamlined.
I did an extensive journey down to Spain from Northern Scotland this spring. Fuel consumption varied considerably dependant on conditions. On a good rural road in flatish country the best I got was 10.1 L/100km (28mpg) at a steady 90 kph.(56 mph)
The worst, in the black mountains was 14 L / 100 km (20 mpg)
I have taken the plunge and fitted a chip to the fuel system by "Chip Express".
Recently done the West Highlands and returned 11.5 L / 100 km (25 mpg), that's pretty hilly but not as severe as the French mountains. Due to lack of Aires I was carrying a full water tank, on the refill when you can principle.
At the end of this month I am going down to Portugal so will then get a better average consumption figure. Will report further.
What is immediately noticable is a significant improvement in torque and a much wider power band, possible to get down to 1500 rpm in 5th with no apparent stress or discomfort. Overtaking is now an option !!
So, so far, so good.
I have decided that I don't really like front wheel drive, mainly due to lack of grip on loose surfaces at low speed. More than once I have had to reverse out, throwing the weight onto the driven wheels. ( Some Mercedes come with a diff lock, but not a chance with a Fiat)
As for the automatic question, I personally am much happier having more control over the ratio in use and engine rpm. I'm not familiar with the 3 litre Fiat engine, but imagine that it will not be disimilar to the 2.8, but with a more modern fuel control system.
BTW, what convinced me to buy the Knaus was that I could stand up inside and draw the curtains on the bed and drive away.
 
True or False

Are these real mpg figures (worked out by the old method of dividing miles traveled by fuel put in) or computer fibs from the LCD panel on the dashboard?
 
Mine are from Red / Full give and take a few miles. Going to add up at the end of the year the fuel bill against milage and see what the :pc: is............
 
Our Homecar is built on an 07 renault master auto and is an absolute pleasure to drive. Love the auto box ,not sure about mpg but think its ok. Dont write off an auto box without driving it though, works well on a bigger vehicle

All worked out with a calculator and fuel receipt. No computer on my ancient beast.

I use a spreadsheet to enter miles from the odometer & trip miles, fuel in litres which is almost always when I fill up. If I do a partial fill I just note the amount of fuel & add it to the amount when I fill up. Might sound like a lot of messing but I created the spreadsheet years ago & had it on my PDA, took about a minute to enter the 3 figures while the wife would be paying.

From this spreadsheet I get the current mpg, the average mpg from new, how many litres per 100km & average. My mpg is over 25k miles in almost 4 years both here & in Europe, interesting that I can see a steady rise in the mpg average over the time, also the results I am getting now are almost always above the average with the odd exception. This show that the engine does start to give better results as it gets more miles on it. My tank is a useful 100 litres which gives me 600 to 700 miles.
 
the old fiat 2.8 is [especially the idTD ], for some reason , much more economical than the current 3 litre

I know several people with 3.8/4 tonners and manual gearbox and they report 22/23 to the gallon driving the 3 litre steadily ; at a guess the auto is thirstier
 
We have just arrived back from France with our Autotrail Mohawk on a 3.0 Auto and got a return of 25 ish mpg ove 3000 miles - bearing in mind we will travel on all sorts of roads (except the toll ones!) I think that is pretty good. This is also using the autocruise whenever possible as well.

The autobox is not an autobox in the true sense of the word - to my knowledge it is a standard manual box and clutch with some technical 'push me pull you' things to operate the gears. Therefore, no torque converter and should be no more use of fuel.

Don't forget that it can be driven like a manual as well without using a clutch pedal........nice!:cool:
 
Miles per gallon

I used to own a 3ltr Tracker and you could watch the fuel gauge go down. I now have a 2.3ltr and fuel consumption is very much better and improving as the engine loosens up. Although the 3ltr is probably one of the best engines ever produced and well on top of its job there is a premium to pay at the pumps. The 2.3ltr needs a little winding up on the hills but it's a super smooth power pack and very economical. You need to bear one thing in mind when going for the 3ltr on the lightweight chassis and that is it is fitted with 15 inch wheels and the speedo reads faster than it should and will definitely use more fuel than the chassis fitted with 16 inch wheels.
