I highly doubt many of the items in your list will be changed prior to production. However I feel it's extremely likely that the 4 drive modes will be modified to provide additional options since so many reviewers disliked this aspect of the car. It seems like a mere software change that would be easy to work on independently while they're tooling up for factory production.
And I absolutely love your idea of a "Stealth" mode. If they had called it Stealth mode Honda's marketing could spin it in a positive way, similar to how Tesla was able to generate press attention for their "Insane" and "Ludicrous" modes. Quiet mode simply sounds boring, exactly the opposite image that Acura wants to create for this car.
Great points.
For that matter, would it be interesting to have something beyond Track mode where there is overboost on the turbos, full charge unleashed on the electric motors (like hot lap on the 918), exhaust bypass, A/C compressor switched off, maximum torque vectoring and all nannies switched off?
What should they call it?
Psycho Mode? Hero Mode? Superman Mode?
Or how about Senna Mode?
On second thought, how hard would it be to allow the driver the ability to customize the number of modes, and the names and settings of each mode? As part of such programming, Honda could also offer customization of the gauges and displays to go along with each driving mode.
That would provide personalization that today's consumers expect. What other car manufacturers currently offer such an option?
I do like the fact that the IDS offers the ability to change everything at once to provide a specific experience - especially if it can be customized. It seems far more convenient than having a separate switch or knob for every system (e.g. suspension, DCT, steering, torque vectoring, throttle, exhaust etc.).
I would guess that if I could customize the settings, I would only need or use three: Stealth, Sport and Senna. Four seems overkill to me unless I am missing something. I would think that I would use Sport 75% of the time and the other two modes for special occasions. In Sport Mode, I would like the suspension and torque vectoring optimized for neutral and agile cornering, the exhaust to whisper around town and roar when I am going for it (like our 1st Gen cars do), full control of the DCT and moderately firm suspension settings. Then the other 2 modes can be set to the 2 extremes of the continuum.
