The auto gearbox is absolutely amazing !
By the past, I had an Evora S with the AT, but it was not really nice to use. The up shift was not fast at all, and down shift was even bad. You couldnt go down in first gear in hairpin bend (even if you could go down in first below 50km/h, in real situation, it was impossible to do). Now, it's quite as fast as every double clutch gearbox. I went on track with it, was really nice, the problem was I got a black flag due to the noise (106dB). The only complain with the AT is the lack of a LSD, but I can't feel it on main figures.
Another great point for me, regarding the AT is the sound when you up shift, it's like a crackering noise, a big bang at every single change. You cant hear that with the manual !
The only "issue" you can't get the open/close exhaust button fitted like on the manual or previous Evoras. I assume is due to a different ECU mapping, but impossible at this moment. It's really annoying when you go on track, as you'll be black flagged on quite every track day.
