What's the best and worst mpg you are achieving in your A Class 7.5mtr 4.5tn gross 170 - 180 Hp Euro 6 AUTOMATIC MOTORHOME (breathe in)

Which one ? Fiat or Mercedes generally gives better average mpg ? What's your average Adblue consumption ?

3000 miles UK to Spain via old non toll roads in france, back to UK with Fiat 150bhp manual, plated at 4.0t but probably running at 4.5t 🤫 we got an average of 25 mpg.
Happy with that considering my daily driver only gives me between 10.5 - 12.0 mpg

Don't see the point of this thread, you spend over £100k on a Motorhome does it matter if it does 22 or 26 mpg.

No, not at all to us. But, I do find it interesting. I found after about 10k miles in our last Ducato based MH there was a gradual uplift to about 10% more than when it was new. I am just curious to see if the Mercedes-Benz delivers the same. I don't track the mileage, or worry about how often I fill it up. I set the trip to see how many miles we do on a jaunt.
Safe and happy travels.

Depends how far you are driving it. Fuel is usually the biggest cost of our jaunts. My forthcoming trip will probably cost close to £600 in fuel. I suppose you offset that by pitch cost savings. :ROFLMAO:

Is there anything you don’t like about your van, looked in one a few months ago, Mrs liked it but I didn’t think it had enough storage ie e bikes in the garage etc

put that way.. no point really..

however.. by tracking it on an app such as Fuelly , if there is an unusual drop in MPG it can alert of something amiss ..

I had a Honda CRV which I tracked, it returned about 30 mpg .. then for no apparent reason it suddenly dropped .. I discovered near side rear calliper had seized..

It also helps develop a more economical driving style.. a kind of challenge to try and do better ..

Just bought one of the last V6 mercedes on a 5.5t sprinter chassis hoping for 20mpg 🤞🏻

Loved our V6 lovely sound. Around 20mpg about right(y). Has it got air on the rear as the Mercedes can wobble bit. They didn't use to be able to add it to the front but that was a few years ago.

Yes full VB factory fit air on the rear and VB FSD shocks on the front as you say Terry they don't do front air on the sprinter rwd.

I think you have to look at driving styles and weather manual, comformatic or automatic and where you travel as well. I get normally get 30mpg out of our 2.3l 150bhp 4.5t Autotrail Delaware rarely going over 60mph, but didn’t do as well travelling through Spain.

Interesting comment you make there about driving styles.
During my HGV training (class 2 and 1) I was taught to try and keep moving, even when approaching and moving out, on to a roundabout. The fine art is to slow down enough to place yourself into a gap in the traffic without stopping, providing there is an appropriate sized gap. The reason is to be fuel efficient. It will take more fuel to propel a vehicle from a stationary position than a slow rolling motion.
The same can be done for traffic lights. I usually let the hot heads to race ahead, activate the lights to green and move through without stopping.
Doing this during a nine hour drive would be very beneficial for the fuel economy. It would also be worthwhile for any motorhome taking to long drive.
I've literally driven through busy cities with very little stopping and without annoying anyone behind. Obviously, there has to be a certain consideration for other motorists. During my test day I had to bear in mind that making another motorists take action to avoid me was an instant fail.

I've noticed that some motorists actually want to stay behind a hgv. They've tailed me at 50 on the A road, had ample chance to overtake on the dual carriage way, yet they just behind my trailer. Strange. It never really bothered me, but in my own car, it does.

Wow - do they really do 10 mpg plus? That’s amazing! I’ve had daily driver cars that do less!! 😉

It's all down to how you drive I suppose. As sn owner driver I drive it steady, let the truck do what's its supposed to do and don't rag it. Even when I've done the odd bit of general haulage pulling 28t loads I've got 10 mpg, and with a non aero dynamic 15'5" high, 14 ft wide boat on weighing 15t, I've managed 12mpg.
On the other hand, an employed driver might only get 8mpg cause they don't pay the diesel or have to replace brakes or tyres, so it's nothing to them flooring the brakes coming in to roundabouts and flooring the accelerator coming out of them.
Still hurts though when you have to put 450 litres of fuel in it :swear:

Yea, but 450 litres is some loyalty points 😀

I think I got around 25 mpg but I do like to get there! Also I found that when I go faster it gets into the quite high geared 9th. Merc 4:5 T A class

Same here, 4.5 t loaded to about 3.8t sprinter auto, probably on motorways I like to do about 60 to 65, slower roads around 50 or less. I recon I average around 26.something if I am lucky. Often heard people saying they are getting sound 28 mpg, don’t know how they are driving though to achieve that. My Mercedes app shows 26.2 mpg average over the 10K miles we have driven it, but my Roadtrip app shows the odd trip as little as 23.5 and on one trip I managed 39mpg, didn’t expect that. I’ll have to recall that trip and figure out what I was doing well! Most trips on average are around 26th though.

Just checked out Fiat 140 bhp 9 speed automatic, 3.5 tonne total mileage 4500,over 3000 miles done on French Toll, and Spanish motorways at 65 to 75 mph then done some town / village mileage
Average 29.4 mpg, but all depends on how heavy your right foot is , and those who have same Fiat the gearbox goes up and bands ( some say gears ) like a prostitute's petty coat !!🥴

Our Merc V6 4x4 PVC has managed 19mpg average over its 10,000 miles, taking it steady and predominantly on-road so far. Plus 10L of Adblue every 2 or 3,000 miles it seems.
Thirsty but worth it for the relaxed drive it provides.

If you’re bothered about fuel consumption, I wonder if this pastime is for you?
Actual measures are of dubious value anyway but, having owned both Merc and Fiat base vehicles I have found that the Fiat is more frugal on fuel. The more important measure, in my mind, is the joy of driving and I consider Mercedes to be streets ahead of Fiat in that respect.
