For the SS, I'm not sure I'm buying the argument that the 10 speed is more responsive. Here's some data from Car and Driver:
2016 SS auto: https://www.caranddriver.com/reviews...c-test-review/
C/D TEST RESULTS:
Zero to 60 mph: 3.9 sec
Zero to 100 mph: 8.9 sec
Zero to 120 mph: 13.1 sec
Zero to 150 mph: 25.1 sec
Rolling start, 5-60 mph: 4.0 sec
Top gear, 30-50 mph: 2.3 sec
Top gear, 50-70 mph: 2.7 sec
Standing ¼-mile: 12.3 sec @ 116 mph
2019 SS auto: https://www.caranddriver.com/reviews...y-the-numbers/
C/D
TEST RESULTS
Zero to 60 mph: 3.9 sec
Zero to 100 mph: 8.8 sec
Zero to 130 mph: 15.4 sec
Rolling start, 5–60 mph: 4.2 sec
Top gear, 30–50 mph: 2.3 sec
Top gear, 50–70 mph: 2.6 sec
Standing ¼-mile: 12.2 sec @ 118 mph
Look specifically at the "Rolling Start, 5-60", "Top gear, 30-50 mph", and "Top gear, 50–70 mph" metrics. I'm not seeing the 2019 performing significantly better than the 2016. This is SS data and not LT (2.0T / 3.6) data, so it's possible the story changes with those engines. I just wanted to throw in some data to the discussion.
