I didn't think Mazdas 6 speed was that bad. It was smooth (when I drive good loaners). But honestly, the volvos 8 speed is the best transmission I've ever had. It's like driving butter around. The turbo in it kicks in at 1200 rpms (I think it's twin scroll) and just has power always available. Most times, it doesn't even need to downshift going up steep hills. Just a little more gas and it actually gains speed! Never had to floor it. It's impressive for a 4500lb car. It feels incredibly solid. Couple that with my hatred for Mazdas infotainment and love of volvos, and it's just all around better.
