Does the dynamic mode engage the trac dsc, and therefor we have less control in case of drifting or not?
some people red this on specifications but it's not to be found on books. so i think i got the response. it does engage it and there is less stability.
I noticed in dynamic mode, if you are in sport mode each gear stay longer, but if you are not in sport mode at low regime , the gears speed actually pass goes much faster, and you find yourself at 30 miles an hour in 4rth or so very quickly , like 1,2,3,4, and its real cool.
The little downer then is that you can't have the "dynamic mode noise and firmer ride" if you choose to have the full stability control on.

I think to separate these options will be cool, so one button for more noise, one button for a firmer ride, and one button for trac dsc so you have more traction. Then you still can have a firmer ride or more noise without being on trac DSC

 

Dynamic mode (checkered flag button) does not turn on trac dsc. that is a seperate button on the console. You can set it to track dsc or turn off dsc completely with the traction control button.

 

Dynamic mode is standard on face lift XKs (ie those with the JaguarDrive selector rather than the "J" gate). Here's what the handbook says: Dynamic mode co-ordinates the vehicle's control systems to deliver a high performance driving experience. This setting enhances key vehicle systems so that the vehicle's full potential can be exploited. The vehicle's responses are aimed at involving the driver more in focused and purposeful driving, helping swift progress. The MY12 brochure states that when Dynamic Mode is selected, Trac DSC is engaged and engine torque delivery characteristics and gear shift points are modified to improve responsiveness. So performance and handling are both affected. (Trac DSC is an alternative setting of DSC, with reduced system interventions. With Trac DSC engaged, traction may be increased, although stability may be reduced compared to normal DSC. Trac DSC is intended for use only on dry tarmac, by suitably experienced drivers. Trac DSC should not be selected for other surfaces or by drivers with insufficient skill and training to operate the vehicle safely with Trac DSC function engaged. Again, from the handbook.)
The exhaust note sounds different to me although this is very hard to track down. XKs have a semi-active exhaust system while the Rs have a fully active system. The active exhaust valves are opened in response to engine speed and throttle angle and the workshop manual has a table showing the relationship. However there is no mention of a difference when Dynamic Mode is selected so it might all be in the mind or it might just be that the opening point in the throttle position/RPM relationship is arrived at sooner.
Overall I'd say that Dynamic Mode enhances performance and exhaust note and relaxes the handling constraints of traction control and dynamic stability control but the effect is pretty subtle. Mind you I have a 5L so the performance is fairly startling anyway. My advice is to arrange a test drive and decide for yourself but based on my experience of a 5L X150 and my previous car, a 4.2 X100 XKR, I think the system is extremely good.


its on another xk forum.

You rather know it before messing around, if you want some noise and a firmer ride, you're in for much less control. Bye bye the track mode / dynamic mode... I don't se any difference of power, and i can accelerate much more when all is on, sometimes the acceleration can be totally different, and i got plenty enough of power in normal or sport mode.

there is roads made of asphalt that are very slippery even dry, I don't advice to accelerate with track mode on these like i did yesterday, maybe my rear tires are near good to be changed too, at 12000 miles already.(original dunlop but from 2009 indeed) , almost 4 years now and the gum is a bit dry maybe. I am going with pirelli for less miles but a "sticky" handling hopefully...

 

In my car (2012 Xkr-s), there is definitely a difference between dynamic mode/ dsc on and with dynamic mode/ trac dsc. The traction control intervenes much sooner (lower threshold) with the former. In my car the dynamic mode firms up the suspension, makes the throttle more sensitive and opens up the exhaust (much louder). The traction control button operates independently from the dynamic mode. This has been my experience and what they taught at R academy. Maybe someone else can chime in

 

the question Ive been having about the Competition mode vs Sport....what are the differences?

it seems like they both do the same thing....higher shift points, quicker throttle response, less restrictive traction control

 

Go out to your car and feel the rubber of your tires - I will bet you the rubber is VERY hard. The OEM Dunlops age rapidly and harden, which means you get very little traction. After 4 years I guarantee you the tires are shot (and actually beyond their specified lifespan) Change out your tires to a good summer tire and you will be smiling from ear to ear with newly discovered grip. I put Michelin Pilot Super Sports on my XKR after I realized the Dunlops were shot and it was like driving a different vehicle! (And there is no way the OEM dunlops are worth the price premium over the Dunlops).

 

you meant over the michelin, i heard these michelin were better but usually michelin tire , i really don't like them, as there is no grip , it last , it cost and has no caracter, again i heard the new michelin were better suited but i also heard one guy having trouble with those and i don't like Michelin. I will get the pirelli p zero cause i am a concerned at security and what i want is a sticky handling/feeling. thanks again. You convinced me to changed them earlier, I still have 10000 km easy (more than half left) on the front but I will go and get 4 new ones, for a better steering balance too.

 

sport does not stiffer straight the suspension. it may if you accelerate but a different way that when you are on dynamic mode.

 

This is from the 2010 XK Technical Guide:

When Dynamic mode is selected (via the JaguarDrive selector), the ADCM increases the sensitivity of the continuously variable damping system to its trigger inputs (roll, heave, steering input, lateral acceleration, etc.).

In doing so, the system then provides increased damping in reaction to vehicle motion – generating firmer body control and more immediate handling responses.

 

Unsure what you meant by selector, the only way i think to set the dynamic mode is to push a button, with the flag one, from the round selector i can only set to sport mode. Correct me if i am wrong.

 

It is indeed a button but that particular document seems to refer to the whole unit as the JaguarDrive Selector in the description and pictures.

Other documents refer to it as the JaguarDrive System when mentioning the buttons as well.

 

yes thanks, from the jaguardrive system/console...

 

Ah, no wonder on my Jaguar Alive autocross runs in an XKR, the traction control kept ruining my fun, even though I had dynamic sport mode on. The instructor kept yelling at me to not jam on the gas, which I wasn't--traction control was just cutting in and out abruptly!

 

It's strange TRAC DSC can't be turned off compeletly.

With Dynamic mode engaged, DSC OFF, i still get a blinking trac control light as i step on it around the corners. (12 XF)

 

Have you tried holding down the DSC button for over 10 seconds because if you do that the DSC should be disabled completely.

 

maybe you mistaken the slip differential control that will always been present jaguar said, even with track dsc off
