Supercharged XFR is the fastest Jaguar ever at 225mph

I would take this over the M5, but with the money I would opt for a CTS-V over this.

well.. there are different buyers for the 3.. id say this goes after the high end mercs (not the AMG versions).. those are really refined cars with lots of power.. where as the M5 is refined but with a strong focus on drivability.. and the CTSV is just smart money if you ask me. you wont see the CEO of a fortune 500 company getting a CTSV... but maybe driving this jag instead of the standard merc.

personally i love it. i dont think jag has been able to shed that old man stigma that caddy has been able to manage very well in the last 10 years but any movement to the younger crowd is a good one. younger in this sense means the young baby boomers, and late Gen X

I drove the XF supercharged for a while, and liked it. This should be even more fun.

Now, if they could only fix those headlights.
This is what they SHOULD look like, in my opinion:

This is a lovely car and if I could be assured quality and reliability will not be an issue I would also choose it over a dime a dozen (though not as cheap) BMW.

The lights look... OK. They should be more agressive and Jaguar will surely remedy that with a facelift.

The interior is a tiny bit of a let down like most Jaguars are but that gershift knob is a stroke of genius, compared with the genius of underachievement of the column mounted gearshift levers in many MBs and the 7 series (puke and super puke).

gus i hear you.. the headlights were a disappointment. i wonder if they offer cats eye covers for this car

Hector- You say "and if I could be assured quality and reliability will not be an issue I would also choose it over a dime a dozen (though not as cheap) BMW"

Here you go -http://www.jdpower.com/autos/ratings/dependability-ratings-by-brand

According to JD power Jaguar is second fiddle to Lexus, ties BMW and leaves Merc in the dust.

For you ney sayers dont forget JD Power is based on actual warranty claims for all cars sold and not one car bought by a third party to remain neutral (Consumer Reports) in other words, a much broader survey giving a more accurate picture of reality and not perception!!!!

I love this car it looks classy and sporty but everytime I would buy the M5 and drop the badge from the boot for the wolf-in-sheep vibe

This car is FAR better looking than the 5 and MB.
But the gear selector is silly and right next to the cupholder. One tiny spill and it's over...

I think the reason this was top secret is because it never happened. I just don't see how 510 horsepower is going to get a heavy sedan to over 225 mph without some serious modification. The Jaguar XJ220 was lighter, more powerful (549 bhp) and more aerodynamic but only managed 212 mph until they took off the catalytic converters and remapped the ECU. Even then it only managed about 220 mph.

As I thought, it now appears that this XF-R car was tweaked to "over 600 horsepower." Since that's what the Corvette ZR-1 has and it can only manage about 205 mph, I'd guess the Jag was tweaked to considerably more than 600 horsepower. Still, this version looks prettier without those stupid Focus-esque chromey side pieces. Maybe getting rid of the drag from those is all it takes to go 225 mph...!

Roy, i agree with you on most parts but you can't compare this jag to the ZR1. The ZR1 has a really low top speed because it retains basically the same transmission ratios as the Z06. This means that 6th gear is very tall therefore requireing a lot more power to reach it's "ideal topspeed"

This car IS modified, but the modifications are not very substantial. I would estimate it still generates less than 600hp with them.

Also, this is an official Jaguar claim, it's not done by a small outfit.

Once again I come to the defense of my favorite brand.

The modificaions were as follows:

-Nitrous oxide to cool the intercooler, that way you get the coldest charge of air possible into the engine.

-No catalysts

-Modified airbox

-An aluminum undertray, smooths out the airflow under the car

-A modified front splitter and rear spoiler

-Racing fuel, most likely 102/103 octane

-The XFR has two intakes in the nose and one was blocked off.

How do I know this to be true? This all came from the horses mouth and that horse is named Mike Cross.

Does it use f1 racing fuel,like v-power?

by justinhk2000 #14, Posted: 2/20/2009

^v-power is a kind of shell gasoline with additives that clean your engine. this is the standard 90(us) octane, F1 cars should use more than 100(us) octane.
