I changed last year from deisels to an SV AB. I decided to be green and can get into emission control zones in cities!!
I tow 2.5 ton of caravan and yesterday towed 150 miles M25, M1, M6 with cruise control set at 55 and acheived 20.6 mpg.
I was most surprised as cruise at 60 gives around 17.5mpg. Have been trying different speeds etc to see what I can achieve now I am let loose again, more out of interest than economics.

Most of you seems to drive around as some careful hockey mom's gettings numbers like SWMBO. I average around 15 l/100km or that would also be 15 MPG.

3.6 TDV8

 Supporter and maintainer of EDF - Mrs Edfors' shopping cart.

Long term average 19.7 MPG, quite a lot towing a trailer, the OH actually has a worse fuel average when she drives it..best 28.5, worst 10.9

So how big is the tank in the S/C L405... I take it it's smaller than the 105lt L322 then...?? Pete

Seems weird they would use a smaller one for the diesels, I wonder what goes in place of the missing 20ltrs... Pete

Adblue?

As above, I wondered if that could that be a change from when the diesels became Euro6 compliant, and needed adblue?

Then I worked out that in my MY13 it costs around £107 to fill up from near empty, which at £1.30 a litre for Diesel is 82 litres, so 86 litres for Diesels makes sense.

My SDV8 405 does 600 miles to a tank, wifeys 5.0 322 does 300 miles to a tank...

Reading this thread with interest. I am currently in the market for a L405 and have just sold my 2013 D4. We have just returned from a 2 week holiday to the scottish highlands in the d4 and covered 2500 miles in 2 weeks. Over the 2500miles we averaged 32.7mpg which I was very pleased with but it looks like I may be even more impressed with a L405

Are you after a 3 or a 4.4L? The 3.0 will probably give you better fuel economy than the D4. The 4.4, perhaps not, unless you drive it like a monk. At a constant 80 mph on motorways I get 32-33mpg from a 4.4, but local/A-roads will give less delight.

For me, it’s a moot point: I drive 6,000 miles a year, so we are talking a few £hundred a year difference on a car that was originally £100k+. That’s where too many people get hung up when they could just relax and enjoy the luxury

I’m pretty sure the diesel fuel tank shrank(?) by 20L for MY16 onwards (Euro6 / Adblue).

I’d echo the 32ish mpg figures - I seem to have this as my long term average for motorway and rural roads. It does fall off a bit when I get into a traffic queue. 2016 SDV8 AB

Got my heart set on a 4.4. Had a L322 4.4tdv8 a few years ago and it was a stonking engine so I can only imagine the L405 with more bhp and less weight will be even better. Could never fault the economy of my L322 as I could easily match or better what I got from the discovery

Going to look at a couple of cars tomorrow  Paul
