Best Saloon Diesel Fuel Consumption

donutheadhomer

Hey

Been searching on google and lots of conflicting/misleading information

My wife is in the market for a saloon under €10k, diesel with best fuel consumption. She drives mainly motorway/N routes but some rural/urban too. Lots of recommendations Diesel Mondeo, octatia, passat. Can anyone here recommend particular models please.

They're all gonna be good to be fair. There won't be much in it.
Something with a 6 speed Box will have a bit of an edge.
Be aware that added technology to improve fuel consumption/emissions could end up biting you too so you might spend your savings on repairs.


Octavia is in a lower class size wise to the mondeo or passat, it'd be in the same class as the jetta/focus/corolla type cars.

6 speed 2l diesel. Theres plenty of choice but I find it much easier to get mpg out of big diesels than high strung 1.6's


Vectra sport diesel does surprising mpg

I would expect an Octavia to be a bit better on fuel than the likes of a Passat or Mondeo as the Octavia is from the segment below the Passat and Mondeo so it is a smaller and lighter car. The Octavia is a also a hatchback btw.

Avensis saloon is a good solid car, I used to get 50mpg + easy from my 07 2ltr diesel hatchback without sparing it in any way. It's a bit bland, no worse than an Octavia though.

50mpg now sounds more like it. Hard to know though really as bigger engine is more tax too.

Big heavy cars need decent size engines to move them about without stress. Putting pint size engines in them is a false economy as the engine needs to work harder and use more fuel. Motor tax is a small part of car ownership yet lots of people seem to base their entire buying decision on what is affordable to tax.

Mazda are moving to bigger diesels with a lower tune a essentially low stress engine. And gives better mpg than the 1.6 unit.

The new 2.2 is ment to do 60 odd mpg

I know just showing my point that smaller isnt better. You can get better mpg and have less mechanical problems with larger diesels

I'd like to try one of those. Because their old 2.2 wasn't especially light on juice.

That goes for every car though.
Most family saloons that are sold in 1.6/1.8 and 2.0 will normally do better MPG in the 2.0, especially extra-urban driving.

Nor was it noted for its reliability. I just hope the new Skyactive engines will be reliable in the long run - though let's face it, they could hardly be any worse than the RF series engine.

it is hard to beat the older diesels are better than the newer ones, the passat red i gives exceptional returns, new does not mean better in the diesel engine world.

Newer ones aren't nearly as bad as they are made out but if you're buying one you do need to keep your eyes open.

I think engine size is only part of it. It also depends on your driving style. I tend to hand onto the revs to about 2.5-3k and get a fairly consistent 45mpg from a 2 litre diesel (44 in a 2.2 Mazda 6 previously) and I prefer it as it overcomes lag somewhat. If I was to keep it to 2k revs and it's close on 50mpg over a tank. If you're prepared to take your time and drive economically you will get decent economy from even the smaller ones but you need to be prepared to go nowhere particularly briskly. A lot of people simply don't understand the difference in driving a diesel meaning they can't possibly eek anything approaching good economy relative to a petrol equivalent.

I think the TDI is better though. More powerful and enough torque to spin the earth.
Comfortline is a must.:pac:

The best saloon car on diesel I ever drove was a 2009 Passat 2.0TDI Bluemotion. You might have to stretch your budget slightly to get a good one though unless you go for a high miler.

My Saab 93 averages 51mpg. Its a 2007 1.9 tid.
You'd get 2008 or 2009 one for €7k to €8k.
Lovely car to drive.

My Passat CC Bluemotion is averaging about 50mpg which is very good imo given it's size and weight. My previous BMW 3 Series averaged slightly higher. Both 2.0 litre and better than my previous Volvo S40 and Ford Focus that were 1.6 litre diesel.
