I really can't help it..... LOL. People here who actually own these with the auto have to argue how they work with somebody who took a test drive once.
Agressive downshifting with the paddles, uses the rev matching feature just like the manual. No other auto trans I've ever experienced has even done anything close. If you don't "believe" it then by all means go take another test drive and get the sales guy to help you.
Also.... when down shifting, the car won't "speed up" if you take your foot off the gas like you're sposed to do when you're.... down shifting.
