Downshift Into First?

Rev-matching is "blipping" the gas pedal to get the revs up while the clutch is in, to match with the gear you are going into. When done right, this makes for the smoothest shift feel, no surging or lurching.
Not sure about "over-winding" tho???
Note: With these new "sport" automatics that let you change gears manually, there is no clutch work, so I guess there is no way to rev-match? While I am still very new to manuals, I could tell today that these sport-shifts are not nearly as fun as true stick. Not as rewarding control-wise, either, tho it does allow you to power out of turns by downshifting. When coming to a stop, there is no need to downshift it, it automatically goes to 1st gear.

I must say, though, in relation to Maury's response- I was test driving a mazda6 manu/matic today, and around town never needed to rev past 3000... so trying to keep the revs above 4000 seems high to me, especially for low speed turns.
I'm not sure either - 4000rpm is turbo wound-up and enough leeway to upshift without it winding down - maybe he's talking about race-cornering?
Around town I generally upshift before 3000rpm unless I specifically want to kick the turbo in - about 2800rpm. You don't get the seat-hugging acceleration but where's the point in that if the next red light is only 100 yards ahead anyway. (Of course the option's always there if you feel like it...
)
I think I overstated the need to baby it before - so long as you're above 1000rpm or so, you can coast and even build speed.
I wouldn't worry about rev-matching, double-clutching and the like until you're comfortable just shifting in a manual.

no need to downshift to first, all u need is second, and or u can use 1st for going up hills from a dead stop, dont ever down to 1st if ur already moving, even a little, if ur car rolls just use 2nd.
