Default dynamic mode on S/C

After 2000 mi. on my 2011 S/C, I still can not feel/hear any difference when dynamic mode is engaged (except slightly higher shift points of the tranny). I definitely used to feel (and hear) the difference on my 2010 5.0L N/A.
Any thoughts?
Also, the engine induction sound inside the car under acceleration is not as sporty/'snorty' as the N/A.
Outside the car, the exhaust note of the S/C is nice and beefy, but can not be heard inside.

You may have the wrong impression of what Dynamic Mode is. That's almost a misnomer, it's less a "function" and more a "deactivation". It makes things less automatic and leaves more responsibility to the driver for a more active driving experience. With the exception that it locks TracsDSC on to help protect the driver from himself. :-) Description is below.

• Press button briefly to activate/deactivate
When active:
• TracDSC is automatically selected
• When Jaguar Sequential Shift is selected, up-shifts are fully controlled by the driver
• Selected gear displayed will change from white to amber as rev limiter is approached
• Cannot be active at the same time as ‘Winter mode’


Cheers,

I hear you steve,
but it's not exactly the experience I had with my 5.0L N/A.
For example, driving a long up-hill road under moderate/brisk acceleration - when I activate dynamic holding same throttle position, it does not downshift, but immediately aceelerate a little faster and the engine induction noise is sportier. This is a definite seat of the pants sensation - every time. It may be also a result of 'quicker' throttle response.
In the S/C, I dont have these changes going same roads doing same thing.

Also, whatever is written in the owner's manual is approved by lawyers. Not the whole story.

I've heard the same thing from others. It is normal. The SC version doesn't seem to show the same type difference noticed in the NA cars.

I haven't played around with the "checkered flag" much yet (only had the car for 10 weeks or so), but I tested this a bit today. Going 50 km/h on a straight the engine had about 1750 rpm. When I then held the checkered flag button for a few seconds it revved up to 2000. I had manual gear selection, so it wasn't due to a shift, just so it's mentioned. Not a big difference, but still a difference.

However, in that mode and the gearbox in sport it was almost uncomfortable to drive at low speeds, touch the gas pedal ever so softly and you get nudged ahead. I solved that by going very fast. No nudging at all.

Completely different car to drive from "regular mode".

Oh, and I finally got my average fuel consumption up to 17.5L/100 km (13.84 MPG) when in dynamic mode!

(Yes, I'm in the oil business).

Doesnt the NA cars have a tube from the intake that runs to the firewall like other cars have to give the driver a lil hint of the motor roar? I know nissan and ford cars have them, I laugh everytime I see them.
