Not exact same swing, but same tempo. Iron's are meant to have a descending blow, which means you take a divot after you make contact with the ball. This gives the ball enormous backspin. The backspin gives it lift and stability, giving you the ability to hit shots with high precision. If you did that with the driver, you would give it to much backspin causing it to balloon and you would lose distance. You need a sweeping, more level swing with the driver. You can still swing harder with the same tempo, but I find that the only time to do that is when I have a long carry to a fairway.
