RC:

The C4 GTS Cab reaches speeds up to 280 kph pretty fast but speeds over 280 kph are basically insignificant because it takes forever until you reach 290 or even 300 kph. Absolutely worthless. This was the first time I missed my 991 Turbo S.  Luckily, I also have the Shelby GT500 for the Autobahn. The C4 GTS Cab is more of a nice weather/bad weather/curvy roads car but it sucks on the Autobahn.
