Aholbro, you are trying to defend someone saying this discussion is about a one tenth difference in the quarter mile. Or even one tenth in 0-60 times. None of your quotes do that, because I never asked about why our cars can't turn 1 tenth of a second faster. It was an attempt by Doug to reduce the conversation to a trivial difference and criticize the merits of asking the question asked and discussed. 4 tenths of a second to sixty is, IMO, not a trivial difference.

I'm talking about .4 0-60. Which is a huge number. Then (to illustrate the massive difference of of .4 0-60), I point out that .4 is huge even in a 1/4 run. The talk about 1/4 was to establish context and scale. I have no idea what our cars run in the quarter... But where is the talk about .1 in the 1/4 mile being a topic of interest? That's Doug's talk, not mine, as you quote him saying exactly that below.

...at 4 second 0-60 rather than (God-forbid) 4.2 seconds but other than that, what is the point?

... No, not hand wringing and misplaced and endless fixation over '1 tenth in the 1/4', give the thread another read and you'll see that the only one talking about that is you.

OBJECTION! (your honor) "the attorney is projectiing on the plaintive..."

LOL... Not a listed objection. Maybe 'misstates the record' if you could quote me doing so. Only Doug says that the topic was centered on why our cars don't do .1 of a second better in the quarter, done IMO to try to trivialize the conversation, when in fact that's not what anyone was talking about a much larger performance difference, .4 to 60. Pretty obvious.


Sorry,

Skeeter

I'll probably regret peeking back here but it seems someone is getting testy. Even took the trouble to search and see how many posts I did and what I post about--a bit voyeuristic, no?

Doug,

Come on, not trying to put you or your car down. Hell, you bought the XK_R_, so performance must matter or have mattered in the past. just recognize that Jaguar is trying to compete on the world stage, and being faster and still elegant is a must. If you don't care about the former as much, understand that some of is bought a faster car to go faster. Doesn't seem hard to understand.

Apologies if I stepped on your toes making the point,

Skeeter

Yes, lots of research... See your pretty picture listed up with your name? Look over to the right. It shows how many posts you made. Click your name and it lists your posts. Thought I'd do you the courtesy of seeing where you were coming from, hardly an FBI background check. I'd be flattered if you'd read my posts, for real...

Peace,

Skeeter

If I wanted to be King of the Drag Strip, I would have bought a Nissan/Godzilla GT-R.

I bought my XKR because the XKR experience is far more than just 0-60 or 1/4 mile times. Beauty trumps Beast every day!

So, we're now on the 3rd page of this post, and I've read far more than I want to know about how much .4 of a second matters. Enough, already!
I'm sick of this and I won't take it any more!

Aren't you, too?

These guys hit 0-60 in 4 seconds flat and quarter in 12.3 with a stock 2010...

I get that the XkR isn't only about speed. But, to repeat myself:

"I'm not sure what's up, but I will admit I'm surprised so many of us are ok having such a fast and powerful car under deliver in this one frequently benchmarked aspect. "go buy a corvette or GTR if you want fast 0-60 times" does not get the point or explain the numbers."

Remove the image, cover the body in cardboard, and estimate 0-60 based on the numbers. I don't know about you but I would predict at least low 4s. It is not too heavy at the specs I cited to be a low 4 or even high 3 second car. Soft suspension helps in a drag race, so that's missing the answer also.

Why is the answer to numbers that don't seem too add up that the XKR is a "prestige" car and shouldn't be expected to be fast?

Can we agree that the numbers indicate more? Seriously, less than 4,000 lbs, 510 HP, 461 lb.ft from 2500rpm=... 4.4? Can't find another car that slow with equally impressive power and power to weight (with so much torque).

The prestige value of the car is irrelevant. Those numbers should produce more than I can produce. The board seems to be putting down similar times. Why?

"Because it is a beautiful car" is NOT an answer. Why are we so eager to downplay speed expectations of a 510 HP car? A car that feels like a missile from 40-100, or from 75 to 155?

Can we please talk about that rather than why we shouldn't be driving our silk slippers like a cheap Mustang? In a safe environment, I drive my car VERY hard. Not abusively but hard Prestige be damned, these cars go like lightning and have godlike brakes... I spare nothing keeping it in perfect shape but bought it to enjoy it in all aspects, hence the XKR and not the XK. The fact that the car is incredibly elegant is no explanation to what the thread is asking.

Sorry to sound argumentative, I'm really curious about this issue, no hard feelings to anyone, just want to focus on the explanation to what looks like a riddle.

Skeeter
+1 Very well put.

Anyone know what the 0-60 time is for the 2008 XKR? From what I understand my car has 420 HP and 413 ft/lbs. I have never been a drag racer and i don't go crazy on the street I prefer road tracks to learn how my car handles. However, I admit I am curious what the 0-60 time is since that is the first thing people have a tendency to ask about cars like ours. I will admit to a lifelong need for speed.

Default XKR vs Gran Turismo

a nice little comparison chart too for you DRubinitz. Reports like these make you feel great about the car you just purchased

Those are serious numbers for the 4.2. So the 5.0 should be 4 flat or in the 3's with good launch!

Just interesting that nobody on the board here has reported better than a 4.4, and that's the 2010+ XKR's! I amid I've slacked off this topic, too much rain and too much going on to have time to try and beat this rather unimpressive high water mark. Need to look into bigger rear Rubber, no word on what maximum rear size would be on newer XKR's, that's held me back a bit.

Question: since traction is a HUGE problem in launching, wouldn't smaller rims, say 18"s, with more flex in the sidewall almost certainly help getting better 0-60 times? Wider than stock and we'd have a double improvement...

Gotta get this sorted out. A week of no rain and less personal chaos and I'd be putting in my time.

But for now, 4.4 is the best the board has produced.

Absolutely...if they'd fit and not reduce too much airflow for brake cooling or negatively affect handling or any of the electronics related to that. Consider a stickier compound tire to achieve the same on stock wheels to avoid all that.

I'm not an expert in kinematics, but 0.4 s difference to reach a certain distance (quarter mile) versus a different speed (0-60) is very different. I wonder which is more drastic!

Skeeter, I understand your quest and I do tire of some folks attitude that performance should be so irrelevant when driving such a vehicle. I do love the acceleration but wonder what I can do to keep the beast from going sideways on me when the cap is on the Grey Poupon and I decide to punch it. It seems that the only practical and someone obvious suggestion that has thus far been offered is to change tires. I happen to have 19 in and have thought of putting some different size tires on when the time comes to change, and I would have thought by now in this thread that some useful information could have been offered to this end. I have seen some comments on other threads with respect to 20 in wheels and higher profile tires offering better traction. Can't we focus on this type of discussion rather than if the "need for speed" is a worthy aspiration?
