RE: 50.4 MPG

I had a look at all the Evoques registered on Fuelly.......... Someone has logged 62.9mpg for an SD4! Think it might be a bit of a suspect entry that one!

A Pangea Green New Defender 110 First Edition is now sitting on my drive alongside British Racing Green Electric Mini Cooper SE Level 3. After 21 years in my hands my TDI300 90 was handed on to the next custodian on 15 July 2022.

RE: 50.4 MPG

If you judge your consumption from the trip computer Auto setting, it can be missleading, for example.
On a journey from home to birmingham I would do about 20 miles of normal roads with traffic and then get on the motorway as I get on the motorway my average will have been about 35, as I travle further down the motorway it will gradually increase to about 42 if I stay under the speed limit. Lets say ?I then stop for a brew, when I set off the Auto trip resets its self and for the rest of the journey ?I will get easily to 48 mpg, until i come off the motorway again.
What i am trying to say is that trip A or B will give you a much more realistic average consumption, but the only way to get an acurate figure is to brim the tank, run it almost empty, brim again and divide the number of miles by the number of gallons user

RE: 50.4 MPG

That's what most of do anyway. I think you'll find that is the case for most of the MPG figures quoted here - we know how the trip meters work.

With the possible exception of that 62.9 figure..... not any of the LRE's trip meters could be that optimistic!

My fuelly figure has just been corrected to UK Gallons, now a more respectable reading.

RE: 50.4 MPG

It's bound to drop a bit in the coming months, with colder temperatures and winter diesel.

RE: 50.4 MPG

Yes, using things like the heated screens, heating, heated steering wheel and seat heaters puts a big load on the alternator and increases fuel consumption.
I was recently advised that I shouldn't ever leave the car idling on the drive to warm it up, just long enogh to clear the front and rear screens otherwise there can be enough particulate generated to give the DPF a very hard time and that means even higher fuel consumption when it goes through a regeneration cycle

RE: 50.4 MPG

I wonder by how much these mileage claims were overstated.

Not being particularly knowledgeable on these things, I've never really understood this. This is my understanding of how vehicle electrics work: the engine turns and a belt linked to it drives the alternator which in turn keeps the battery charged. How does putting a higher load on the battery make a difference to fuel economy? Surely the alternator's being driven the same irrespective of the load?

I'm not disputing it does make a difference, it's just I'd like to understand why it does.

As Energy systems cannot be 100% efficient, The more load you draw from the car's system the more resistance the alternator has against turning, therefore more engine power is required to turn the alternator, therefore using power that could have been used to drive the wheels and so costing you mpg.
