Please help

Which is better the V8 or the V6 S type ?
V8 is fuel hungry but fast , Has anyone any idea what sort of mpg you get -
mostly highway ?

   I don't know how this is possible, but Edmunds.com has the V6 version of
the S-Type listed as getting 18/26 mpg (City/Highway) while the V8 gets a
near-identical 17/26 mpg.
   How this plays out in the tarmac of reality I do not know.

Bigger engine in same weight of car does less work. Choice is more a
matter of preferred feel rather than fuel consumption. V6 is available
as a manual and the V8 isn't. The manual V6 is the sportier option.

I have 1,400 miles on my V8  S-Type;  and so far the computer says I am
doing 14.9 MPG.  I drive it like it was stolen;  so hopefully your mileage
is not that bad.

V8 beats V6 everytime.

I used to have a 4.2 straight 6 Sovereign and  a 3.5 Litre V8 Rover, and
although the Rover had a smaller displacement, it left the Jag for standing.

If you want fuel economy buy a mini - Jags are for enjoying !!!

Lighter car; different gearing. You are not comparing the engines
here. Twin ohc Jaguar XK - five times a Le Mans winner - far superior
engine to pushrod Buick V8, even if it was all ally.

>If you want fuel economy buy a mini - Jags are for enjoying !!!

As are Minis, Stu (the real ones - not the BMW thing). Some of us have
both.

Ive owned both. The V8 is stunning but i rarely acheived above 17MPG whereas
the V6 would deliver about 20MPG. Ive just bought a new 2004 XJ6. Ive gone
for the 3litre. Ive only had it 2 days but am returning 21MPG

We have a 2003 XJ8 Supercharged Vanden Plas with the 4.0 Supercharged
V8 engine, we have owned her for around 3 months now. The computer
states that we are getting an average of 26MPG, however I must state
that around 80% of our driving is highway driving.

Seems rather good to me. No idea what the V6 model S-Types will get,
but I would assume it will be no worse.

We have a 2003 S-Type R (Supercharged V8) with 14,000 miles on it.
Its mostly used for a short daily commute and has made a couple of
Pittsburgh to Ft Lauderdale round trips.  Its also been out on the
north course at Beaverun for some very hot laps.  The trip computer
has never been reset since it was new and its average fuel mileage is
holding at 23.4 MPG.  Not too shabby, if you ask me.

Neither of them - Only engine good enough to sit under a leaping cat has 12
cylinders - AND DEFINITELY NOT A DIESEL !!!

I know you are troling and I shouldn't bite, but...

The most significant engine in Jaguar history is not the V12, it is
the XK. A straight six, twin ohc engine sketched out in wartime and
built to power the post-way big saloons. It was launched in the XK120,
which was never intended to be a big seller but became one and spawned
a long series of sports and sports-racing cars, right through to the
E-type Series II. During this time it won Le Mans five times in 'C'
and 'D'-types. Available in sizes ranging from 2.4 litres to 4.2
litres, it also powered the compact saloons in all their variations
and the first three series of the XJ6. It was in production in its
many configurations for more than 40 years, continuing to power
Daimler limousines and Alvis light tanks long after it was replaced in
the mainstream cars by a new straight six.

Don't get me wrong, the V12 is a great engine.  A very minor player in
Jaguar history compared to the XK, however, and certainly not
deserving of the statement above.

David,
  You are right, you shouldn't bite!!

This is a guy who thinks the ONLY car that is truly a Jaguar is the XJS-V12.
He does not care about Jaguar as a marquee OR the Jaguar history.
Ironically, NO Jaguar from 1968 until the modern line came with a leaper
from the factory -- including the XJS.  In fact, I don't believe there was a
Jaguar made from the factory that EVER had a V-12 and a leaper!!   It was an
"add-on" from the dealerships.  The XJS rarely had a leaper added any way,
it had a growler badge on the hood.  Most owners thought the leaper on the
XJS was as silly as the leaper on the XKE.  The XJS he drives was a design
and product of British-Leyland, if I am not mistaken. And finally, the XJ40
was initially designed as to purposely NOT use a V-12 in the production,
which is why the Series III cars were produced to handle the V-12 sedan well
into the 90s.
   To dis-regard the history of the XK engine in both production and racing
is to dis-regard the history of the marquee. He might as well say the 1988
XJ40 was the only proper saloon ever made by Jaguar!!

Cheers

Leapers were banned in the UK and Continental Europe as part of Vehicle
design safety Standards, they were also banned in Australia and are only now
being reconsidered for introduction by the Federal Vehicle design standards
branch.  Maybe we will get these again, maybe not.  Jaguar Australia are
pursuing this.  The XJ40 was purposely designed not to include the then
Rover V8 (Oldsmobile parentage).  Leyland did not want to continue with the
V-12 and wished to include the V8 which the Jaguar design people and
engineers thought was considerably inferior to the V-12.  The V-12 was
included in the XJ40 when Ford gave the go-ahead and the front end was
re-engineered to take the V-12 as was originally intended.  The Series III
was contninued with the V-12 because the demand was still there and until
the XJ40 could be produced to include it.  It took some considerable
persuasion on the part of Jaguar to convince Ford Brass to lob the V-12 into
the XJ40.  By tyhen Ford were concentrating on the X300, a much simplified
car which returned to Vacuum brake boosting and rid itself of the stupid
hydraulic suspension.  The revised AJ 6 engine was much refined over the
Xj40 version along with better ECUs primarliy because of newer chip and
software development.  The later V8 again improved the smoothness although
still has some incredibly stupid coolant pipe design.

The development of Jaguar is an object lesson in why Governments should
never be allowed to get into business decisions.  The Leyland experimetn was
an absolute idsaster of not only Jaguar but the entire British motor
industry.

The XK was also a notorious oil leaker, which the Jaguar engineers
steadfastly  refused to rectify. I was apparently part of its British charm
and was thus responsible for sealing more highways with oil than any other
production engine. Rumor has it that world petroleum inventories gradually
increased as a result of scrappage of XK engines over the past 20 years.

No, you shouldn't bite but you know you love to .. Just as much as I love
looking at things from a slightly different angle ...

This has to be one of the best newsgroups around -

I bought the 05 S-Type with the V8 and so far I have been extremely happy.
I didn't like the noticible lack of power in the V6 version of the car (test
drove it).  I would have bought the S-Type R;  but they only had 2 of them
and I didn't like the color choice in one, or the lack of the touch screen
in the other.     So far I have added a JaguarXP air intake system.  Dealer
installed it (had like 30 steps,  looked like a pain to do);  and it adds to
the growl sound of the engine and [allegedly] added some horsepower (I can't
tell the difference).

I met with a sound system group (Tweeters) that has a kit to add DVD movie
capability to the touch screen.  Think it's worth doing?   I should add - it
was not inexpensive.  It was about $2K to add the functionality,  an Alipne
6 DVD changer in the trunk,  and 2 Alpine monitors in the headrests.
