Ref. 2013 X150 XK 5L

I'm trying to establish the exact functions affected by the various driving modes. The owner's manual is vague, saying that Dynamic mode "...enhances key vehicle systems". I believe what the modes do is this:
Dynamic: More sensitive throttle response
Sport:
More sensitive throttle response
Stiffer suspension
Auto transmission up-changes at higher revs
Permanent manual transmission selectable by paddles
Delayed DSC intervention

Is there more to Dynamic mode than this?What I can't work out is the difference between Sport & Sport+Dynamic? Can anyone clarify definitively?

Thanks in anticipation,
Michael

 

For true hyperbole, the 2014 XK brochure is an excellent resource:

Dynamic Stability Control intervenes in demanding driving situations by applying braking to individual wheels where necessary, reducing engine torque and helping to maintain stability in the most challenging driving conditions. Adaptive Dynamics continuously monitor the car’s speed, steering and body movements, analysing the suspension response and varying the damping to suit conditions. The system calculates the appropriate suspension response 500 times every second keeping the vehicle flat, stable and secure. This array of driving technologies is designed to assist but never overwhelm allowing confident, precise handling without any loss of ride comfort.

The XK driving experience is taken to the next level through engaging technologies that enhance handling, response and performance. Jaguar Sequential Shift™ provides a choice of Automatic or Sport mode. Quickening the shifts, Sport mode exploits the full power of the XK engine. It is designed to monitor driving style and varies the shift schedule holding on to lower gears for longer. For total control, manual gearshifting can be selected utilizing simple one touch paddles mounted behind the steering wheel.

JaguarDrive Control™ offers further enhancements with Dynamic and Winter Modes. Engage Dynamic Mode and immediately the XK is more responsive. The engine torque delivery characteristics and gear shift points are modified to improve response speed and sensitivity. Winter Mode is designed to aid driving in slippery conditions. The accelerator pedal response is dampened to help reduce the risk of wheel spin and to help maintain progressive wheel control. Its bespoke shift settings delay and soften gear shifts for improved grip.

Clearly they didn't do development work on the M25 on a Friday night.
