I have an S-Type 4.2SE coming up to 4 years old and 60,000 miles. According to the on board computer (which I'd say is a bit optimistic) I get around 23mpg without giving general driving any thought. Occasionally I have driven at a steady 70 using cruise control on the M25/M11 when visiting my son and usually get an indication around 34mpg. When going to Le Mans each June, driving at maybe 90-100 on excellent French roads, I get maybe 19-20mpg.

A problem with the S-Type is that the tank is only 60 or so litres, so the range is not particularly good...this can be irritating

I have the 3.0 X-Type, engine is great, the car feels just the 'right' size, a huge amount of grip and quite good handling. I have not driven a 4.2 S-type, but I would say that there is not much in it when it comes to 'feel'.

I get 21mpg locally and about 24-25mpg on the motorway. Boot and interior space is bigger in the x-type, but it really comes down to looks I feel. I like the post 2004 S-type, but the wife does'nt. The extra space and 4wd did it for me.

Downsides, well the consumption is high, my suspension is now beginning to feel tired at 75k miles, and the auto box can change at odd times, sometimes. Other than that, the quality is not as bad as people make out, and it DOES feel like a Jaguar, not a mondeo.

i prefer 4.2V8, much smoother, better 6-speed auto box, faster, better ride/handling, sounds better and yet very similar MPG figures/runnning costs...IMHO no contest.

what is average overall fuel con figs?

i would say around 24...

MPG for local driving?

19-20mpg

MPG on an 80 mph cruise?

late 20's possible early 30's if careful...28mpg? the X would be slightly worse here in my expercience.

Following on from the above....

I am now on my second S-Type and there's no doubt the newer models are much better all round compared to the original edition. The 6 speed gearbox, interior etc is a vast improvement, and the economy of the 4.2V8 is a little better than the early 4.0V8.

I have driven various X-Types for a few days at a time and they are OK, but I much prefer the S-Type. A good pal has an excellent 3.0L Sovereign Estate, fully loaded. He is pleased with it (he had an XJ6 Sovereign previous to it), and likes the 4WD and capacity of the estate. He is disappointed with the MPG and is experiencing something about the same or less than me! IMHO the only advantage of the X over the S is the capacity of the boot, and maybe the 4WD if you use it cross country regularly.

I've had the pleasure of both of these cars - X type is much tighter and more of a drivers car, the 4.2 S type is more of a wafter but is very very fast!

I managed about the same mpg in both (25-28mpg) and if I were to get another I think i'd get the S (honestly I get an S type R as I can't resist blowing my budget when I get a car!!). I suppose it depends what sort of driving you are doing though - if mainly motorways I'd defo go for the S whereas A & B road journeys the X would probably be better.

cheers guys - most of driving is commuting 6 miles out then 6 back - occasionally I get to escape to the Dales - 200 miles on motorway - then blasting around the lanes - is there much difference in width?

Can either be very slightly tweaked to enhance engine character? - I like the sound of both configurations (in other cars)

I was surprised to read that the 4.2 is 'very, very fast' - does it really pull that strong? (top speed of no interest) - does the 3 litre X sling itself down the road? - Currently drive a 2.5 Omega and 4.3 Griff (the Omega is a lot quicker than I expected, and the Griff, well she moves at quite a pace too..) - fed up with 23 mpg average, prefer high 20s if possible.

When did better better build and trim come in on these models - Unfortunately, being a Carer my budget is limited so I shall be aiming for the cheapest no hassle good spec car!

Very fast is 0 to 60 in 6 seconds dead, limited to 155mph. The 4.2 is 300bhp (earlier 4.0 is 285bhp i think). Not as fast as the griff but even if it was it wouldn't feel it as its quite civilised.

The 3.0 X-type kicks out a jaunty 226bhp 0 to 60 in 7 seconds dead.

Not sure what MPG you'd get from either of them a 6 mile commute though!

I agree with Ali D's comments regarding the S-Type 4.2. It is 300bhp, and does 0-60 in 6 seconds dead. It also carries on pulling strongly up to maybe 140ish.

When I got mine 4 years ago, I did consider the S-Type R as well. However, as most of the auto mag reviewers said something on the lines of "the R is a tad disappointing but the 4.2 SE always exceeds expectations", I decided on the "ordinary" 4.2. Performance wise, it's been great for me.

It's due for the 60,000 mile service and MoT tomorrrow, and there should be no problems.

Lone Granger,
I drive a 2.5 X sport manual and I've had 2 of them and you won't get more than 25 mpg, the extra weight of the awd and mechanical resistance mean the duratec 2.5/3.0 same engine is a thirsty little beast expect the 3.0 to run 1 mpg less and auto's to run 1mpg less than that, full to empty tank is achieved at between 300-330 miles depending on how hard you hit the loud pedal.

thanks for info - just as i was tending toward the 3 litre auto x type... - oh well, no worse than Omega - presumably c 29mpg on a long motorway cruise?

The 4.2 s type fans are claiming 0-60 in 6 secs - now that is genuinely quick - does it feel that quick? - does it sound nice inside when booting it? - I couldnt here the Monaro for instance - totally strangled..

funnily enough not quite as quiet as a standard monaro which i agree are WAY too quiet (hence my Wortec exhaust wink ) but not really much to get excited about noise wise, hence why the new XK has active exhausts cool

Lone Granger, My S-Type 4.2 SE in truth doesn't feel quite that quick but 0-60 in 6 seconds dead is the official time and has been matched by most auto reviewers. What does feel really quick is the ongoing acceleration through 60 and upwards to 100 and more. Great!

As for sound, it's pretty well silenced except for the short period when the engine is cold (the V8 warms up unusually fast). I have been in a 4.2 SE with a special exhaust (Paramount fitted I think) and that sounded really nice, not overly loud and intrusive but good and grumbly.

Feeling quick and being quick are not always the same thing.

A couple of years ago I went to California twice in fairly quick succession, Te first time I was given a TBird as the rental, the next time Hertz gave me an XK8 convertible.

Well the TBird seemed much quicker till you looked at the speedo, where as the XK8 didn't seem very quick till you looked down and saw how fast you were going.
