Default The design of the the XK8

When the XK8 was introduced in 1996, it was the cutting edge of automotive technology in many ways, and Jaguar had presented several papers to the engineering community detailing the design concepts.

I have collected these on my website and provide a link below for those interested in this snapshot of automotive history: http://www.thejagwrangler.com/jaguar...nd-papers.html

Some of the information can also be useful to help understand the design better when diagnosing difficult problems or making mods.

Enjoy!

Glad to see lots of you are finding this of interest!

There is definitely some cool XK8 trivia here.

I recall that when I was looking at and considering buying an XKE back in the mid 70's I kept hearing about "electrical problems" with Jags.

The thing is that I don't know of any cars from any other manufacturer in Europe, Asia or America that is plagued with "electrical problems". That is not to say that there not some issues with some of the more high end cars, but I don't know of any American car that has such issues.

What is it about Jaguar, specifically that there are still so many issues about the electrical system? Clearly, they have designed a system that is subject to a multitude of electrical issues. Is it just due to their line of thinking or what is it exactly?

Isn't the chassis and suspension nearly the same as the XJS from the early 80's? I wouldn't call that cutting edge.

I recall that also, but I think that he is talking about some of the other aspects.

I think that this was the first V8 that Jaguar produced, and though the initial engine had some problems, they were pretty much resolved in later versions.

I remember back in the 60's and 70's when the American car companies put out a totally new car every two, but mostly three years.

It as always said that you should not buy the first year of that new style, but wait until the second year, when they had a chance to correct some of the mistakes of the first year.

The new 32-valve twin cam alloy 4.0 V8 with a servo controlled throttle introduced in production on the XK8 in '96 was a pretty impressive piece of engineering, even though in hindsight there were a couple of significant flaws with the early ones.

Moreover, these articles discuss the networked electronics at length. The XK8 was one of the earliest luxury production cars that had a fully networked infrastructure, where nearly every aspect of vehicle operation was controlled by computers talking to each other over data networks. This design was important not only to Jaguar, but to Ford, who was investing heavily in the technology. New in '96, this technology, in more refined form, is today's mainstay in almost every automobile.

That's probably about as good an answer as we are going to get.

As quoted by Steve M

Actually none of the suspension or chassis is from the XJS, they never took XJS parts and threw a new body on it. The design of the XJS floor pan was utilized in the design of XK8 The engineers thought they had a good basis from the XJS plus the cost savings. The rest of the car was cutting edge for early nineties. This information is in Jaguar XK-8 by Philip Porter who was one of the engineers on the project.

Yeah, back when the XK8 was about to be released, there were a whole bunch of different articles about it in the car mags. I remember when I first started reading about it, I wanted one but figured I'd never afford a new one. Now I have one and the extended honeymoon is still going on. The XK was very innovative when it was released.

Excellent Read, I remember seeing the first '96 at the San Francisco auto show, what impressed me most was they had jacked up the cars and spun the wheels so the logos where all face up. That attention to detail had me hooked.

Why do the English drink warm beer?
Lucas refrigeration!

This is true only when referring to either European or American cars. I've yet to own a Japanese vehicle of any year of production that would render your statement as accurate.

Read the sentence above the one that you quoted for proper context.

Sorry for confusion. I will clarify. I have owned several Japanese vehicles, which I either purchased or leased as new that were 1st year of production models and, which have never given me any issues at all. I have also owned (leased) a few German cars (Mercedes 350E, Audi A6 and Audi A8) that gave me plenty of issues (mostly electrical gremlins). The German cars were NOT first year of production, so most glitches should have been fixed in previous years of production.
I guess what I am saying is that Japanese cars are better engineered than European or American cars. Having said that, the driving experience IMHO is far better in a European car than a Japanese car.

Your sample size of 2 is adequate to state that as fact. lol

Not a fact. More of an opinion based on over 20 years of driving experience and personal observation. For more factual evidence, reference Consumer Report reviews and JD Power surveys, which are based on large amounts of data.
