A friend who works in a Jaguar dealership phoned to day. He asked if I still
had my SL55. He said I should go for a test drive in the new aluminum
XKR with a new engine giving out over 500 hp and weighing very little.
He said it would make mincemeat out of my SL and said another branch
had sold one to a guy with a SL65, he said it made mincemeat of that too.
Anybody in the States seen or driven one. I intend to find out just how quick it is.

It's a nice car,that's all.
Not much lighter then XFR (same engine) which in turn is slightly slower then SL63.
Nothing really to worry about....

jaguar vs sl65 very amusing... very!

Glad to see Jag has finally put a 500 HP engine in the XK. But at 4,100 lbs with 461 ft lbs of torque and reported 1/4 mile times of 12.6 to 13.1 seconds (http://www.fastestlaps.com/car_Jaguar_XKR_510_bhp.html) it's safe to say it won't be spanking any SL65s.

A jag that beat a 65 HMMM ... This I would have to see with my own eyes..

Hang on, don't just dismiss it. 500 bhp with a weight of 2 tons makes it power
to weight 250, a SL65 with 600 bhp at about 2.5 tons gives 240 bhp power to weight. I realise the torque is down but driving is believing.It should slaughter my 63 at 214 power to weight. It's booked for Tuesday, rain permitting.

Looking forward to reading your report. I think you'll outrun him.

Not trying to be rude but your posts are inaccurate with alarming consistency.

The SL65 does not weigh "about 2.5 tons" it weighs a hair over 2. Power to weight is right at 300bhp/ton. Off the top of my head your SL63 is just under two tons so has a power to weight of about 270bhp/ton, just below the M5.

Jag XKR should move well (probably close to 300bhp/ton like the Sl65)and be very comparable to your SL63, however, I'd guess the SL65 would best it fairly handily as outright power and aerodynamics become much more important than power/weight ratio as speeds climb.

I think your 63 just might take it or very very close. Will it slaughter a 65? No way!

I know you don't like me, but cut the crap and stick to the point mr know
it all
The weight of my 63 is on a plaque on the door frame. It states my car
is 2225 kilos in otherwords 2.225 tons, I know a 65 is at least 100k heavier
so 2325kilos in other words, that's 258 bhp per ton.
How do you know that the aerodynamics are better on the 65 than the Jaguar, something you saw sometime maybe

Actually Jag is 1660 kg making it 307 bhp per ton, apart from the torque
why is it so funny to say it may be as quick as a 65.
or quicker!!

actually the weight on the door sticker is gvwr. your real weight is far less.

on the topic - i think the jag will be slightly slower than the sl63 and will be definitely slower than a 65 car.

There seems to be so many different specs all different so I guess an about figure is best, after all somebody has to drive the car and there may be a
passenger and fuel all adding to the weight.
I just get so annoyed by people who poo poo any car that's not a MB.
They are narrow minded, I personally will never sell my SL63, even if the
Jag IS faster, they don't do a convertible with solid roof for a start,
but I always like to try the opposition, that's why I drove the 911 Turbo.
Unfortunately there are too many people waiting to jump on you at the first mistake you make, they get more out of correcting you than talking about the subject. The more cars you drive the more knowledge you have, that's the way I see it!

Sound8,

You insult people who know more than you.... You can never learn that way. People correct you as you are wrong. Everyone has been "on topic."
Ever noticed that no one likes you around here?

-Rob

I never insult people unless they insult me first.
If you are going to reply to one of my posts, why not keep to the subject
instead of getting personal. I realise that my Britishness is different from what is 90% USA members, and there are a few members like yourself who
always make it personal, but I am big enough to take it, because there are members who reply to my threads. Whereas you and your gang will always
pick on anything I say!!
You see what's happened, we are suppose to be disgussing whether anyone
in the States has seen or driven the new XKR and you have turned it into a slanging match.
Ever noticed that no one likes you.....my god playground talk.

New Jaguar XKR:
0-60 mph: 4.0s
0-100 mph: 8.8s
0-130 mph: 14.8s
1/4 mile: 12.3s @ 119 mph
70-0: 160ft
skidpad: 0.92g
wt: 4,085lbs

SL65:
0-60: 3.8s
0-100: 8.2s
0-130: 13.4s
1/4 mile: 11.9 @ 123 mph
70-0: 160ft
skidpad: 0.93g
wt: 4,494lbs

The new XKR is a great car... I personally like it a lot. But the SL65 out performs it easily in a straight line. You can tell above 100mph there is a huge advantage for the SL65. The SL65 runs from 60-130 mph in 9.6s, while the XKR does that same interval 10.8s. What I find amazing is that with 400+ more pounds the SL65 stops in the same distance as the XKR from 70mph ....and displays higher grip around the skidpad. And the best part .... push a button and your coupe becomes a convertible...

Thanks Tom for an excellent and comprehensive reply,I was feeiling a little vulnerable after the last reply. I believe congratulations are also in order.
It looks like the Jag would eat my 63, but I guess that all that torque from the 65 is eventually going to kill the cat. There is one thing though, what
happens if you can re-map the Jag, holy moly it could be seriously quick.
Here's a question, is it light enough to be called a sport scar though
Last time we discussed this a member stated that the SL65 was 2400kg,
maybe that's what I was thinking.
Once again thank you for your reply and bringing some civility to this thread,
much appreciated.

A change of the S/C pulley should give it some more boost and should be done in conjunction with the ECU tune. Arden claims another 30hp from their exhaust. Then again, just an ECU tune on an SL65 should push the SL65 well past a completely modded XKR.

Tom

Yes you are absolutely right, but where does it leave us with nat ***?

Looks like it was a dry day for you. Did you run the XKR? If so, how did things turn out?

You can't beleive the weather here, hurricane winds torrential rain, I am not going to drive it until it settles down. Maybe this Friday!

I have been reading about the flooding. You don't live near the lake district do you?

Im going to cop the new XKR over the Benz. The XKR is better in all aspects and just gorgeous. Jag>Benz
