Morning chaps,
I'm thinking of trading my Laguna in for a 9-5 to use as a motorway barge over the next couple of years. My work mileage has just shot up (from about 400 to 2,500 miles a month), and I fancy something a bit quieter and with a better image for when I arrive at customers premises.
I've been looking at a 2.0t from 99, and was just just wondering what kind of fuel consumption I'd be looking at? (I get 15p a miles from work so have to pay for my own petrol). I'm getting about 36mpg overall out of the Laguna, and about 40mpg if it's been a steady 70-75mph cruise for the whole tank. Would I be much worse off?

Not really bothered about speed or power from the car (I've my 911 for that at the weekends), just need something quiet, comfortable and with a decent image. I'm think the other alternative is a 99 plate BMW 318i if the Saab is going to chew too much juice, but they are just too common...

A 9-3 represents a great compromise for those that want the luxury and refinement of driving a good quality saloon, without the stigma of owning a BMW.



I've just got a 9-3 and am over the moon with it. Looked at a 9-5 but would never have parked it in my road! I'm getting about 32 mpg on my (short) run to work at the moment. That's with a manual box and a LPT. I think the stated figures for combined cycle on the 9-5 ar around the 30mpg mark.

I have just got a 9-3 Aero am getting 34mpg on the motorway at 70+ drops a bit round town, and depends how much you boot it but average for last week was 29.6mpg over about 500 motorway 250 A roads and local running.

btw if you are not worried about performance - my dad has a 95 with a 2.2 Tid engine and auto box - its slow but very good mpg and cruises happily at 70+ and has full spec - something like that might be a good choice for you

FWIW my MY 02 spec (250bhp) 9-5 Aero estate auto will return up to 33 + mpg on a decent motorway run. Round town stop start and a lot of short cold runs will have that down to around 24 it seems. Worst I have ever seen was 22.something but given the sort of use it have been getting it was no surprise.

A bit of winter stop start and about 75% motorway cruising sees me in the low 30's regularly - perhaps a little better using Sainsbury's 97 octane than regular 95 but difficult to be sure.

If an Aero auto Estate can do that I would anticipate slightly better numbers from a non Aero Manual doing mainly motorway work.

Not driven a Laguna but the 9-5 comfort is excellent IMO. That is an assessment compared with my 2 previous barges - Omega Elite and Senator 24V - both of which offered accomodation that would not be out of place in a gentleman's club. The 9-5 is a little smaller and, as an Aero, more firmly suspended, but I can still climb out feeling almost refreshed after a many hundred mile drive.

I have a 1998 2.0t auto Saab 9-5. On a good long run at a constant motorway speed (average for the UK) I can get high 30s meaning about 500 miles on a full tank. However, a more realistic result is 23 mpg around town ( I live in West Yorks so there are alot of hills to go up and down so economy will be compromised ). Personally then, I find the 9-5 to be particularly sensitive to the way its driven and the mode of motoring. Drive it lean and its very good, but push it up a hill and it can be thirsty. I generally average 300-360 miles on a full tank. I guess that a manual may return 1-2 mpg over the auto - but the auto is fantastic as autos go.

Cheers for the replies chaps... I'm wondering whether I might be better off heading towards a 9-3 diesel (99-00 model style). Didn't really want to go that route as I still see it as a Vectra (ducks and heads for cover...), but there seem to be a few in the Trader at a little over £2k with some highish miles on. The savings on fuel if I continue to do 2000+ miles a month might start to add up.

The Laguna is pretty sensitive to speed on fuel too - a 75mph motorway cruise sees 40mpg, but raise it to 80 and you drop to around 36mpg; whilst a sustained 95-110mph run back from skiing at Christmas to catch the ferry saw it drop to about 24mpg which shocked me a lot. My Corrado never varied so much when I had it, but then I guess it wasn't running near flatout.

I had a Merc C200cdi for a week in France once, and despite it being a diesel and cruising at 100+ everywhere on the motorway I seemed to get 43mpg... Really impressed me, but I can't justify the cost for a work motorway hack...

The diesel auto combo is appealing - one of my colleagues at work has a latest model 9-3 in that combo and he's really pleased with it.

You may not see much saving with an old Saab diesel. I have a W plate 115bhp 9-3, and at a steady 80 on the motorway, I get about 42mpg. Currently with alot of town/mixed driving, it has dropped to around 35mpg ). You also need to be careful with the high milers, as things start to go wrong. You need to check if the fuel pump has been replaced (can be £1000 to replace I believe), and that the turbo is in good condition. The air flow meter is a £300 plus job ( had mine done under warranty, luckily).
I really like the 9-3, but think the next one will be a petrol with lpg (if that stays low on tax). I had an lpt petrol and on a lazy 60mpg motorway journey, it was doing 40+mpg.

The new 1.9 TiD is hugely better in every way than the old 2.2.

Interesting points... Maybe a petrol is the way to stay (particularly as diesel continues to get more expensive)... I like the torque of diesel engines, and the sheer laziness, but a nice petrol is always rewarding on the days when the traffic clears...

Don't make the common mistake of thinking of a 9-3 as a Vectra in drag! For a start it's based on the Cavalier floorpan, but so much else is different

Drive both and you will find them poles apart!

What sort of fuel economy could I expect?
Mostly motorway driving, Thanks.

Non-turbo, motorway driving - I would think you should see around 30mpg, maybe a tad more.

My lightly modified 16v Turbo sees 26mpg average, but have got over 30 on a run before.

evening peps
the diesel is a good way to go for fuel economy and drive but is costly when goes wrong ,but saying that my customers with the diesels are doing well !
the diesels are that bad the main dealer sends them on to me!!!!!!!!1
the other thing is that they are a lot more expensive to buy than the 95 petrol, plus i need to sell my t plate 75k 95 new tyres, new turbo, sump cleaned and new front pads £2600 thats a bargin
cheers rik
