I've been told that the DSG gearboxes are twin clutch paddle types which come under the name of S-Tronic. Is this true? Would you rate this kind of box better than a proper manual? My current car (FTO) has a Tiptronic gearbox and my main gripe with this is that it zaps about 20bhp from the wheels. Is the same to be said of the S-Tronic box?
