BMW SMG vs PORSCHE PDK

[Liquidcell]

So I read they can both perfectly calculate in matter of nano seconds and shift faster than any humans.

Which is better? Why?

who knows, but if you mean SMG that old hat.

That was a robotised gear change with robotised clutch.

PDK is akin to DCT (dual clutch transmission)

changes are not made in nano seconds, but milli seconds.

can't comment on PDK but the DCT appears to work very well

Here is how it works
