The dynamic option is an increased speed of 174mph,a bigger spoiler than the standard XKR,A front splitter,side skirts,and a rear diffuser is the speed pack dynamic option and the black pack is similar but no 174mph option,but comes with bigger spoiler and front splitter only.Also each option comes with different standard wheels that i don't know off the bat,so u might want to look it up because the wheels can tell you what options the XKR have on it as well.I can tell u the 100% way to find it by typing in the Vin to find the window sticker on the monroneylabels.com website and that will tell you all the options that it have once you buy the window sticker from there

 

monroneylabels.com window stickers are available only for 5.0L X150 models from 2012 - 2015.

 

Here in the UK, give the VIN number to a friendly Jaguar dealer and they'll give you out the spec as delivered. They did this for me, by exchange of emails.

 

Back to what is in “dynamic mode”. A.K.A. pressing the magic racing flag button:
- stiffens suspension
- prevents exhaust bypass from closing, at any speed, so it remains open
- changes throttle response, such that it is at full open at 75% depressed on the pedal
- raises shift points
- and just discovered…disables speed control

Oh yeah, and since it sounds so good, causes the right foot to press harder on the gas pedal, and consequently MPG goes down.

 

??? Automatic Speed Limiter? I used that once to see what it did, never again since.

 

oops..I meant cruise control. 🙄

 

My ACC works normally with Dynamic mode. Course I don't specifically remember doing it, but I do use cruise quite often as well as Dynamic.

 

^^^\mine doesn’t have ACC. Which is kind of stupid for such a luxurious well featured car to not have that in 2015. Where as my 2010 Acura has it.

 

Adaptive Cruise was an option that seemed to be rarely taken up by buyers - at least here in the UK. When I was searching for my car I came across almost no XKs with it fitted. Maybe it was an expensive option and buyers didn't think it was worth it over the standard cruise control. Some people weren't aware though, that ACC added another capability; Advanced Emergency Brake Assist, which used the radar to sense a potential collision based on distance to the car in front and closing speed and pre-charged the brake circuit pressure, with an audible warning.

 

Oh yeah..,did I mention how awesome the exhaust sounds in Dynamic Mode, even with stock exhaust, when you press the gas/petrol pedal? You tube videos don’t do it Justice. With the top down, it sounds like a NASCAR car. Especially if I go by side barriers and it echoes off them. I think it actually sounds better than my Harley,

 

Remove fuse #19. You will always have that noise.

 

Is there any indication on the message centre display that dynamic mode has been activated?

 

There's a flag symbol in the message centre, and a brief confirmation message.

 

Just curious, why people remover be fuse, when you can turn it on & off with the dynamic switch.

 

Because I don't always want Dynamic mode switched on.

Sometimes I like to be able to drive the car in "S" and still have the transmission change up eventually.

Sometimes I like to burble gently along in "D", enjoying compliant suspension.

 

To follow up on my slightly facetious remark above; I've learned that the XKR is a versatile machine. Yes, it can be a bit of a road rocket. But sometimes, when the top's down, the windows are open, the sun is dappling through the trees overhead and your elbow is hanging out over the door you want a bit more of the 'XK' and a bit less of the 'R'. Dynamic Off/On and transmission D/S provide a total of 4 distinct characters to the car. I've found there's a time and place for each of them. (And then there's driving it in manual - another experience.)

 

Mine are red also, I wish they were black.

 

It also seems to be related to the "mystery" of the rear tires wearing out twice as fast as the front ones.
