Edit: How do I thumbnail these pictures...?
Just got the 2017 Jazz Hybrid Modern Steel Metallic, coming from a 2008 Myvi 1.3L Auto (9 y.o. rattle cage

).
Only driven 40km,
Things I love:
Good Points #1: S-i-l-e-n-t.
Good Points #2: Braking is progressive as hell. Perfect slowdown -> stops transition very very easily done.
Good Points #3: Gear shift? What's that? You won't even feel it during acceleration.
Good Points #4: Below...
Opinion#1: NVH is good (coming from a 9 y.o. car). It's quite insulated. The wind noise + road noise VS speed is very jarring.
Cruising at 80-90 km/h is equivalent to old beater at 50km/h, which is scary. You don't feel the speed due to the insulation. Perhaps Mazda's concept of allowing road noise into cabin was a good idea...
Observation #1: Gear shift
felt, not jerk, @ 40-50km/h during deceleration/coast
Observation #2: Hybrid rolls forward after a short delay (500-700ms) after lifting off brake pedal. Closest analogy would be Proton's clutch CVT I think? Let go brake, wait a short while, only car rolls forward.
Bad Experience #1: Stopped at apex of shopping complex bump (no incline), open door to take ticket (tint, can't wind down window yet), close door, release brake pedal.
Car rolled backwards. WTF'd! Jammed brakes, then press accelerator.
Critique #1: The accelerator pedal is extremely laaaazy. I'm depressing about 2 cm but it's not moving??? Need press down to ~5 cm only car will move. Same behaviour observed during test drive also
Critique #2: Sound system is bloody awful for such a silent car. The old Myvi's stock front 4" dash mounted speakers has more presence.
Rear speakers booming like mad. Vocals are blurry as hell, can't make out anything aside the boom. Short time (10 minutes) in Jazz V-spec 6 speakers also similar thing. Blurry mess.
ICE part
Here's some frequency measurement I took using a calibrated mic, UMIK-1. Processing done in REW.
Methodology:
Laptop Bluetooth frequency sweep and measure with UMIK-1. (It's digital, Bluetooth codec should reconstruct back to flat right...

)
Measure 7 different positions and angles at driver's seating position then Average the frequency response.
Head Unit settings are Bass +0, Treble +0, Sound Effect OFF (Sedan/Compact/SUV/OFF)
A/C was at speed 1. Might have been blowing at mic, I forget. Mic has a wind shield though.
All measurements taken while on EV mode of course

Here's the result. 45dB noise floor / completely silent.

Here's a smoothed version.
Good Points #4: The sound treatment for this car is good stuff. Most frequencies decay after ~90ms.

Extra stuff:
Here's the Head Unit's Bass and Treble response.
Black is the +0 Bass +0 Treble.
Bass -5 ... +5

Treble -5 ... +5

So if I understand correctly , the whole graph thing states that change the HU to those settings to have a good experience ? Got it
