Hi folks,

Currently thinking about getting an X150 model XKR and would greatly appreciate everyone's thoughts on how the 4.2 and 5.0 versions compare.

Is the face-lifted 5.0 model dramatically better than the 2006-2009 4.2 version? Clearly the 5.0 has considerably more torque and power but 510 bhp seems almost a bit overkill for what is a luxury sports GT - unless of course the rest of the car has really well adapted for the new power plant.

After selling my 500 Chimaera I'm looking for a much more modern and dare I say it practical replacement that has a really well judged balance between performance, handling and frankly effortless wafting. Whilst the idea of the 5.0l appeals greatly, it would be a shame if all that extra power came at the expense of the car being a fully rounded.

I've no interest in constantly going sideways or sending out huge palls of tyre smoke where ever I go, but fabulous and every-day usable performance is very much on the want list!

Anyone have experience of both engines? Would I always regret not getting the more powerful car, or conversely is it possible that the vast power and torque of the 5.0l could actually compromise the overall roundness of what will be my main car?

After chopping and changing cars quite a lot recently I'm searching for a keeper now, and this means that what ever I get has to do everything really well rather than simply make me giggle at the brutal acceleration and exhaust note for the first few months a la Chimaera.

I'm assuming that the 5.0 is the real deal but I thought I'd check here first.

Opinions and advice greatly appreciated.

Cheers
TD

I have a 4.2 XKR and at no point in the 2.5 years I've owned it so far do I feel like I've had to "settle" for it, despite my original budget not stretching to the 5.0. It's a glorious thing, very very quick but feels very well balanced for it.

I'd also say the 4.2 looks much nicer than the 5.0, I don't like the front end of the 5.0 cars personally and the interior feels a little fake bling, for my taste.

The only thing that would tempt me out of mine would be a 5.0 XKR-S, but that'll be a few years down the line yet.
Looks wise I can't argue - I also find the newer version front end a little unresolved and perhaps a bit OTT

Guess I just need to get my act together and test drive both models to see how they stack up.

Thanks for the input so far.

Hmmm, interesting!

These very helpful responses are encouraging me to listen to my heart rather than my head, and my heart is - I think - suggesting the 4.2 rather than 5.0 for a variety of reasons.

Cost obviously comes in to it, especially if I am ummmming and ahhhhing anyway, but there are other considerations including the fact that I'm not an immediate fan of the pop up gear selector or the front end. I test drove a 4.4 TDV8 Range Rover the other day and the pop up gear selector did not float my boat much then.

Can I perhaps extend favour here and ask you experts what I'd need to look out for on the 4.2 with regards to reliability? I did read that the suspension needs attention after about 65k miles. I'd rather buy a car with much lower miles but if there are no real problems to worry about then an immaculate 70k miler at a sensible price might well be an option.

Hmm, I just realised that there is another question I should be asking and that is how the the newer 5.0 XK (not XKR) compares against the older 4.2 XKR.

If the new 5.0 XKR is too much of a nutter maybe the non supercharged version might be worth a look.

By the way, that was extremely hard for me to type. I can't believe I am actually considering the slower XK model when I could afford an XKR of the same age. That MUST be genuine proof that I am getting old - and the fact that I recently bought some rather nice sheepskin slippers.

Has anyone deliberately chosen the non supercharged version of the 5.0 XK for reasons unrelated to budget? If so what is the conclusion after having lived with the car for a while? Wish you had more poke or glad you did the grown up thing and went for the more everyday usable car?

It's noteworthy I feel that it's mostly us TVR drivers who don't like the fly by wire throttle pedal. I guess we're quite accustomed to having very fine control over throttle position (well you need it in a car that's notably faster than a 5.0 XKR but without any traction control) but those who haven't got used to TVR throttle pedals don't mind it.

Having thought on this more, I think it's just a matter of fine adjustment rather than whatever curve is on the pedal. Us TVR lot expect to have a great deal of control over throttle input and ankles are not the most precise things for most folk to have control over. A tiny pedal movement results in a massive change in torque in the 5.0 s/c engine in particular and it's hard to really enjoy the chassis on anything but a warm, bone dry road because of the way the car breaks traction ao aggressively.

Part of it might be the Jag's active diff being too effective too. The hydratrak in the Cerbera in particular is a lovely diff for road use that avoids sitting smoking one tyre but at the same time avoids the savage nature of very aggressive diffs which for uneven road use are a bit like trying to run with your shoe laces tied together.

Frankly the feel isn't there in the big and comparitively heavy Jags either. Again us TVR lot probably expect too much from them as a drivers' car. TVRs don't win many races but despite their reputation they are hugely communicative cars, as most purely mechanical cars are.
Interesting points.

I sold my Chim 500 just the a few weeks ago and already miss it. Having said that I simply was not using it enough hence the search for a more versatile car. I guess I could have used it as a daily but as you say, the lack of traction control coupled with what I found to be rather uncommunicative rear end made it a tiring car to cover ground quickly in. That's fine for a weekend blast but not so much for the daily grind of serenely yet rapidly getting from A to B.

I did get the car set up but maybe I should have had another go - or maybe I'm just a pussy. I never really knew how close to the limit I was, and relying on the mechanical grip of the tyres on the wet with no feel for when this runs out is not a exactly relaxing.

Anyway, point very much taken about the modern throttle mapping. Definitely something that will need some recalibrating; particularly since having sold the Chim my transport has been either a Landcruiser or a diesel Mondeo Estate!

As a completely left field addition to the discussion has anyone experience of both the XKR and the E92 M3? Very different cars I know, with very very different engines, but the M3 does have some attraction as a potential next car too.

Well just back from a test drive in the e92 M3 (manual) as this was also under consideration alongside the XKR. Have not managed to drive an XKR yet but there is one not too far away so maybe during the next week I will answer a few important XKR questions for myself too.

The M3 is an awesome car with a brilliant engine but despite being very well screwed together it did not feel quite as luxurious as I was hoping - it was not a well speced car to be fair.

These days being in luxurious and beautiful car that also has impressive sporting credentials is a probably a better mix than being in a high pedigree sports car that is low on the luxury side of things. Lovely seats though!

I'm still tempted by the M3 but I think that 90% of the time I'd not be fully utilising the full ability of the engine and chassis whilst always wishing for something a little more special to spend time in.

Next stop a good shot in both a 4.2 and a 5.0 XKR.

Thanks, Sly.

@TD, I'll be interested to hear what you make of the comparison with the M3, that's a car I do find myself occasionally wondering if I should have a go in.
Looks like it will be a while before I get to test an XKR but I have to say the M3 seems to have left an unexpectedly lasting impression.

This might be because it has been sometime since I owned such a broadly capable car - in fact the last one was probably my last e46 M3.

Sadly the things that were not great about the old one seem to have been carried through in to the new one. The steering rack needs to be sharper. You turn the wheel and the car does not turn as much as it feels like it should. Maybe this is an effort to limit oversteer but it just feels wrong. Also the manual gear change is still pretty disappointing - cartilaginous is the best way I have heard it described. It does not snick in to place as I'd like. And the suspension is still a bit too soft for such a focussed car ( this one did not have the optional dynamic damper control).

However the engine and chassis are superb and overall it is still a bloody good package. I am trying not to think about it too much!

Also as winter closes in up here in rural Scotland the RS4 / tweaked S4 option (see Chris Harris and his revo remapped supercharged S4 Avant) is making a good case.

Living at the end of a 1/2 mile dirt track has many advantages - but easy access in a sports car ain't one of them!

Hey 8bit, used to be up near your area but now down in the central belt but thanks for the offer any way. Nice car!

Feel like I was a bit harsh on the M3 but it is so good that the small areas where it is not completely perfect seem to stand out all the more because of the brilliance of the rest of the car.

Still might get one!

I deliberately chose the 5.0 XK and it has plenty poke. This after coming from two 4.2 XKR's both X100 and X150 models. Same go as the 4.2 but it's the dynamic suspension, noise and handling that is so much better. Got it in May and did a 3500 mile Europe trip. Most excellent. Try one.. smile
Thanks Jeff. Planning to try the 5.0 XKR next week and maybe the 4.2 as well. Will be interesting to see how they compare.

Forgot to add that the 4.2 I have seen has 66k miles on it and is a 2007. Anything major to worry about or are these cars pretty robust? I did hear that the gearbox oil should be changed at 60k so I will look in to this.

As for the 5.0, just how dramatic an improvement is it over the 4.2? The 4.2 is a lot cheaper than the 5.0 (£18k ish vs £31k for a 2009 27k mile 5.0 example).

That is a serious hike just to get in to a slightly fresher 5.0 if I can get 90% of the upside from the older higher mileage 4.2, but if there are light-years of difference between the two cars then the 5.0 might just be worth it.

I'm leaning towards the 4.2 as a first port of call as long it will still be reliable (it has a FSH). If I love it I can always upgrade later I guess.

Thoughts?

Also, I work from home mostly and therefore won't be racking up the miles.

Thanks Iain, good info.

Update.....

I'm abroad at the moment and today my wife decided to go and drive a 5.0 XKR that is on the "possible" list.

Got a text this afternoon. "I fookin LOVE this car!"

She won't even go and drive an M3 now. No point she says; if it is anything like our old e46 then there is no contest!

A small and fully refundable deposit has been put down (with my permission on condition that it is genuinely fully refundable)

Looks like I have a test drive to do this Saturday. I still need to be convinced, but it sounds like it is going to be 3 against 1 - wife, car and car salesman vs me. My usual Devil's Advocate approach to these decisions may not prove to be a sufficient defence, but I'm not sure I want to win this one if the price is right.

I expect you'll love it... but I was looking forward to your feedback on how the 4.2 and the 5.0 compared! smile
I know. After all this careful research and preparation I then go and mess up the test drive strategy.

Logic would say that I should have test driven the cheaper 4.2 first bud instead my wife goes and drives the much more expensive 5.0 first! Never mind.

In preparation for my test drive of the 5.0 on Saturday can someone talk me thought the paddle shift details for this car?

I assume I can start paddle shifting when the car is in Drive right, rather than always having to out the car in to Sport. I test drove a Rangerover the other day and one thing that puzzled me was than when I did use the paddles in D the car would not revert back to manual
unless I put it in S and then back to D. Someone later told me that I could hold the upshift paddle for 3 seconds when in D and this would take it back to auto mode. Is it the same in the Jag?

Lastly, when in sport mode does the car automatically adjust the throttle map, damper settings and the traction control etc, or are all of these things manually configurable as in the M3.

I ask because I'd rather not have to go in to full Banzai driving mode every time I want to use the paddles.

Thanks yellowtang,

That all makes sense. The Dynamic mode button will remain firmly un-pressed given the disgusting weather we have today - well probably!

Sooooooo, assuming I like the car what sort of deal should I expect to be able to negotiate, or at least what elements might be up for discussion?

This car is from the Jaguar network. Obviously price, and the trade in value of the car I'm going to trade but what about warranty and servicing etc. The car currently comes with a 12 month warranty. Has anyone ever managed to talk this up to a 2 year warranty? The car is a 2009 so might be a struggle.

One other thought - this car has the chrome side "gills" and silver coloured air intakes on the front bumper. How hard are these to change to body coloured? Might be something to ask for as part of the deal I guess, as I am not 100% keen on the standard spec.

Well that was an expensive day out!

Picking the car up next Thursday and handing over a rather large wedge of cash + a Mondeo Estate.

The Jag really is a stonking car. Considerably lighter steering than I had expected and consequently less steering feel than the M3 BUT it is such an accomplished and luxurious all rounder that the trade off is well worth it. The heated steering wheel is a very nice touch and the seats are excellent.

The car is extremely comfortable, incredibly well specified and of course phenomenally quick. When in standard D mode it puts itself in a high gear and cruises along serenely using its vast reserves of torque, but put it into Dynamic mode and it sure as hell wakes up! I've driven some fast stuff in my time but this thing is a beast when it wants to be. Dynamic mode will certainly be used regularly. Sport mode is a decent compromise between pace and grace with the car hanging on to each gear for longer. Paddle shifts also good and surprisingly quick for a "traditional" auto.

As predicted the negotiation did not yield much - £500 of the sticker price, half price tyre and alloy insurance and a full tank of fuel but hey, life is too short to spend all day haggling over a few hundred quid.

The car is in great condition, 27k miles, with an excellent service history (service every year rather than on mileage). It is black with charcoal interior and red stitching.

I did not get try to negotiate a free black pack, mainly because my wife was not convinced about it - but I'll be working on this in the coming months as I do like the more stealthy look I think.

Pics when it arrives!

Yup, it was the one in Perth. Glad you agree it looks like a good car.

We traded the Mondeo (Titanium X in fact) after a lot of thought. We also have two 4x4s, one very good - Landcruiser - and the other, well let's just say it is a Disco 2, so we figured that we would not miss the Mondeo THAT much. However I have yet to own a car that is better value for money. Boring as it may sound the Mondeo has been totally superb. I can see us getting another one at some point.

Hoping to avoid too much sideways action in the XKR over the winter but no doubt I will be tempted to carefully explore the handling when the conditions and traffic make it safe.

Update: The TD family is now the owner of lovely (and slightly scary) ultimate black 5.0 XKR coupe.

It is one hell of a car and I'm thoroughly looking forward to getting used to it. I already think I prefer it in Sport mode rather than D since this allows me to dictate what gear I'm in and when the gears change. D mode is great for cruising / slow traffic but I prefer to have more control how the enormous performance is transmitted through the gear box. I have only even driven manual cars up until now and the auto box is really very good I must say.

Good stereo (B&W), great seats, heated steering wheel is a real luxury and the key-less entry is neat.

We had an interesting ride home on the wet, greasy cold roads back down from the Jag showroom in Perth, during which my wife conjured up an underwear challenging moment coming off a dual carriageway roundabout! Happily no harm done (underwear excluded) and the process of recalibrating to the new beast is now well under way.

Not had a chance to drive it since getting it back on Thursday as my wife is away with it this weekend - driving very cautiously I might add. And now it is snowing. Winter button will be used on the way back I suspect.

It's got Dunlop SportMaxx all round just now and they are in pretty good condition so will hopefully be performing as well as they should. That said I'm not sure how well I should expect them to perform when even when new. Anyone with experience of these tyres vs other brands?

8Bit, Should I be surprised of you suggest Vredestein Ultrac Sessantas as replacements when the time comes?

Out for a blast in the wet earlier on today with no dramas - partly because it was a "blast" in to loosest possible interpretation but I did explore a little bit more of what the car has to offer.

On to other topics. First it's got a long old nose though hasn't it? Stopped off in Tesco's and got out to see that I was a lot further forward in the parking space than I had thought. Happily I went for an "I don't know how big my car is yet" space so had lots of room all round.

Last but not least - what fuel do you guys use? I filled up with Super-unleaded today but are they just as happy on the regular stuff?

Thanks a8hex - good to know - and I agree, it is not like the thing needs more power!

I went with Super just in case as I could not find any reference to the recommended octane rating today. My 5.0l Chimaera actually had a sticker on the filler cap that said only to use 98 octane but there was nothing on the Jag filler cap.

Seem to be running at about 22 mpg which is no doubt a reflection my respect for the power this thing has and the fact that it has been wet ever since we got it last week.

Looks great Torque - the best real world GT on the planet I think, despite my fondness for Aston Martin - congratulations and all the best with it!
Thanks!

Yes it is quite a car that's for sure. We did have a hankering for a V8 Vantage but we'd have had to get an older 4.3 and the Jag was better in pretty much every important way really (apart from badge top trumps and styling perhaps)

I had a short blast in Dynamic mode the other day, which was entertaining! Love the sound of the thing when pushing on. I am also not missing having a gear stick which is a surprise.

Sadly the car is back off the dealers today for the usual teething problems to be fixed under warranty. The adaptive headlight warning light has come on a few times and from past experience I have learned that it's better to jump on these things early to make sure that everything is fully sorted before the 12 month warranty runs out!

Anyway, it is snowing here today so its not like we were going to be doing a lot of driving in it. Back tomorrow or the next day hopefully.

Sounds like a good plan.

I get intermittent problems with that warning light showing up, but the dealer can't find anything wrong.
Interesting. Did a bit of research and it does sound like a fairly common issue. I gather it is advisable to get a new battery fitted every 4 years as an old battery can throw up lots of odd electrical gremlins. That said the dealer has ordered in a new adaptive headlight unit just in case - although who knows if they will actually fit it, even if they say they are going to.

Have a brand new diesel XE as a courtesy car while the R is getting fixed. I know which I prefer but for what it is the XE is a very accomplished car. I definitely like the reversing camera - it is the one thing that the our XKR does not have that I'd have liked. I messed about with the paddles on it today and it went up to 8th gear! 6 seems to do me just fine on the XKR but I'll wager the ratios are a tad different.
