What are the differences between an XKR-S and XKR-Portfolio

 

The 2008 XKR-S was a limited edition 'higher performance' version with the bigger Alcon brakes, raised top speed, body kit etc.

The 2008 Portfolio was a special edition version with Alcon brakes, 525w B&W stereo & different wheels and trim.

The Portfolio term these days is used for the 'luxury' trim level package.

This is not the first time that I've read the 2008 XKR-S has a slower 0-60 (5.1) than the regular/portfolio 2008 XKR (4.9).

Can anyone confirm this is actually true? If so then I'm glad I don't have an XKR-S.
To me the benefit of 175 top speed over 155 is mostly juvenile bragging rights, as its not like I'd really find an opportunity to go that fast often if ever. The extra top speed is definitely not worth any sacrifice in 0-60 time, which is far more likely to be encountered and missed in every-day driving.

You'd think at least the Jag marketing boys wouldn't allow the XKR-S to be worse than an XKR in any area of performance.

My understanding is the 2008 XKR-S is baslcally a 2008 XKR just with an uglier nose, lower/harder/smarter suspension, a slightly remapped ECU and a much noisier exhaust. Important stuff like engine, supercharger pressure, gear ratios and final drive ratio apparently remain identical.

 

I Love my 2008 XKR Portfolio and I don't need to have anymore power this car is fantastic.

 

Also remember the 2008 XKRS was only sold in Europe:

From Autoblog:
"Jaguar will produce a limited run of 200 XKR-S coupes, which will be offered in Europe only. Now, the regular XKR is a delectable conveyance that combines endless sex appeal with eye-widening performance. Put plainly, it is an absolute hoot to drive. The XKR-S takes all that goodness and ramps things up a bit. The 420-horsepower blown V8 is unchanged, and the XKR-S has the same 0-60 time (4.9 seconds) as its standard counterpart. What does change is the electronically governed top speed. Adding the "S" also adds 19 mph to the cat's top end, now 174 mph.

Among the myriad other changes made for the XKR-S are the addition of big Alcon Performance R brakes, a retuned suspension, and a host of visual and aerodynamics upgrades, such as new wheels with retro-logo caps, a new front splitter, side skirts, a new rear spoiler, and a rear diffuser insert. Inside, what was already a very nice cabin becomes opulent, with new interior trim, a higher-end audio system, updated instruments (to accomodate the higher top speed) and other sundry niceties. You can sum the whole thing up in two words: "fast" and "beautiful." We want."
