Well, the top speed in 2nd (if info correct) would be 64 mph, so still only one shift required.  It would be significantly quicker - don't know amount.  

Time to 200kph would be much better, as would mountain driving be much more fun, and track driving on very tight tracks will be better too.

Autobahn and Nordschleife will be worse...
