Had a new 2017 impala Lt for a rental this weekend. Awful. Controls were not easy to reach, power was underwhelming with the v6, vision was awful and the rearview mirror was tiny, as Nd the seats were uncomfortable. Plus it had zero features like parking sensors or backup camera.
The trunk was big though.
Probably to do with how heavy and bloated the cars are.
I find that modern engines actually make decent power but they get hamstrung by how the cars are programmed to hunt for the highest gear possible in most situations. I remember my 4-banger camry would have good-enough pickup if I was in manual mode and hung onto the gears.
In auto mode, it tries to stay under 2k rpm whenever possible and only downshifts when you mash the pedal. Makes the car feel very slow to the average person who doesn't manipulate the gears themselves.
I thought that foot on the floor led to the car not shifting when you were wringing it out unless you were going to hit redline? My old subaru does that and auto wrx's from the same era do the same. Autocrossers that drive an auto tend to use the throttle as an on/off switch where it's either all the way on the floor or not being touched at all depending on the course. Anything less than full throttle usually leads to a bit of shifting.
