Several comments. New car - 10 days in use so far.

The transmission shifts smoothly and normally cannot be felt
unless briskly accelerating. Since the engine is still so new, I'm
not pushing the car very much at this point, but upshifts and
downshifts are pretty smooth. If I drive it as a sedan around town,
you can't feel it shift.

When cruising at 60 mph, the trans is in OD and the engine only
turning 2000 rpm. That's pretty steep. When you push down gently on
the accelerator in this situation, the car tries to stay in OD and
acceleration is modest, especially if you are only going 40 or so
to begin with. A stronger push almost always results in a 2 gear
downshift and the engine builds up rpm and you take off. I have yet
to figure out how to get it to only shift down one gear, but I expect
I'll get a better feel for it over time.

I have to agree that the drive by wire gas pedal has more resistance
than my other cars, but part of this seems to be coming from the
mental impression that the car is "unresponsive" to very small pedal
inputs. This is actually true, since it tries to stay in OD. I'm
sure they are trying to improve gas mileage from this. It's too early
for me to see if this impression will go away as the car loosens up a
bit and the computer "learns" how I drive.

Of course, the sport shift is great and the car can really fly when
you want to drive that way!
