Yes, the DSG box is instant shifting

It is not really like any other gearbox out there. As far as I know it is the only one that have 2 clutches, one for gear 1,3,5 and one for gear 2,4,6 .
The electronics senses wheter you are accelerating or decelerating, it then puts the next gear in place, and when you want to change it simply shifts from on clutch to the other, giving you faster gearshifts than you can do with the manual.
Thats why the acceleration is faster than the manual and also constant the whole way up to top speed !
