I took a test drive about a month ago in a '21 301A GT. My last Mustang was a '13 GT. Both M6 trans. I concur with OP in that I found the torque lower on the new car. About 4k is were I started to feel performance. My '13 was bone stock.
Hi Mustang people! Just joined the forum. I am currently driving a non-Mustang but when my lease expires next June I will be looking at a new GT. Very informative content here, my compliments.
