Differences between '93 and '94 XJS models? Need some help, please!

Steve, you're correct about V12's in 1993 US market: I should've known better, since I have in my possession original pages of July 1993 Motor Trend magazine highlighting the fact that the "new" and ONLY engine available (to America's market) is the 4.0L straight six, also describing it as "a better performer than last year's 5.3L V12"..."with 0.5 sec quicker 0 to 60"... "and 0.4 sec quicker in the quarter mile". They also mention that 100 ea. 6.0L V12 XJR-S "Jaguar-Sport" cars were destined to America ("but they're all spoken for already..."). -- So, I stand corrected.

Like I said, when you observe side-taken pictures, the facelift cars hardly look like they really need the body kit, but there's still a difference, of course.

I'll talk to my friend about the XJRS Registry.
Regards,
Reinaldo

They are all great cars, I would like to know however if there are any suspension / steering upgrades on these fab cars to incorporate to "Silver's" portfolio, please join the group also, my car is an 83 so too old to be a member.........darn it....but at least my steed now has the full V12 ..... 6.0 Litre.

There seems to be some misinformation stated above (or maybe not...)

1) There was no 1993 V12 XJS , only 1992 5.3L V12s and 1994-1996 6.0L v12s
2) The 1993 XJR-S is a 6.0L V12 using a JaguarSport bodykit mounted onto a facelift car. 3) The 1993 XJR-S body kit is a combination of the pre and post facelift JaguarSport body kits.
4) The 1994 V12 XJS front and rear bumper covers are very similar to the UK facelift XJR-S pieces, but not quite.
5) Reinaldo, get your friend to joint TheXJRSregistry.org is he hasn't already.

I'll add a thing or two regarding the TWR kit issue.
As we know, the last year for the TWR-inspired XJR-S model was 1993. This XJR-S model featured substantially different body lines/looks when compared to the non-TWR-inspired, pre-facelift XJS, via enhanced, more sporty lower body lines, particularly front and rear ends. The difference between these two cars is abismal.

However, if one places that same pre-facelift XJS side by side with a facelift model (side views are more descriptive), the differences are quite similar as they were vs. the XJR-S car. In other words, the pre-facelift car makes the facelift model look more like a TWR car by comparison, especially when it comes to the front and rear low profile wraparound bumpers/spoilers. Just pick up side pictures of pre and after facelift cars, say, on eBay, and the point is clearly confirmed. In general, the only lower body lines difference between the XJR-S and the facelift car is that the very lowest edge of the body tends to stick more outwards (adds "volume") on the TWR version, whereas on the facelift car it curves in, following the body's natural curvature towards the bottom.

The other difference is that the XJR-S has no chrome on the headlight rims (flat black on earlier models and body color in 1993); no chrome on the hood's front edge strip (flat black paint) and no chrome at all on the top surface of the front bumper (body color). In fact, pictures of my facelift XJS here at the JCNA Gallery, show how I followed the TWR concept by getting rid of the chrome (except the bumper) and having it painted the same BRG as the rest of the car. Only difference is that I went ahead and added the mesh grille to follow the supercharged Jaguar concept (earned by 130 HP worth of nitrous injection) but that's besides the point.

From all this, I'd derive that:
First, Jaguar obviously took the clue from the TWR / XJR-S body style and proceeded to redesign the subsequent XJS year model's body styles (i.e. the facelift cars) to reflect the great TWR-based looks to a good extent, and...

Second, that based on above, there is much less that a TWR body kit can improve over the facelift car as compared to what it did over the pre-facelift model, therefore, there'd be much less justification to significantly re-design the kit in order to make it fit the later XJS.

When I compare my '94 XJS to my friend's '93 XJR-S, I still notice the more sporty and aggressive, better looks that the TWR inspiration gives it; simply awesome, absolutely awesome.

OK, I beat this one to death, but the TWR-inspired enhancement on my own XJS speak for themselves, for my admiration of the features. Of course, the XJR-S 6.0L V12 wouldn't hurt either.....

Few more items, although not necessarily "body" changes:
The convertible top rear window is different because the introduction of the rear seat altered the top's folding arrangement.
The '94 model introduced the rear seats on the convertible in place of the traditional trunk.
The '93 has a passenger side glove box; the '94 does not.
The shifter, with the exception of the very early '94's, changed from a "T" type to the oval knob used on most of the later Jaguars for many years.

The V12 offers additional '93-to-'94 changes:
The V12 '94 introduces the latest style rear spoiler, along with painted side mirrors and painted headlight rims and the new five spoke wheels. None of this was available with the '93 V12 XJS.
Last, but not least, the V12 was enlarged to 6.0L in May of 1993, which would pretty much be the '94 year model here in America.
