I don't know if it's 67mph lol that was a mild guess... 50mph is the best in 6th as most of my trips are single carriage way I get it alot.
I've got well into the 40's with mine on long trips, it's all about patience and music... I don't need to go fast whilst music is on unless someone pisses me off or I am in Cupra R need the toilet mode haha
I didn't think the gear ratio went that low in 6th. I'm starting to think there's nothing wrong with my car after all!
Wow, all these years he was right about the fuel economy.
