I think only the R doesn't auto upshift, the CS45 is basically a CS and that definitely upshifts.
The standard R will upshift at the limiter, if you spec the Performance Pack, it removes this and will not upshift at the limiter. All GTI models will upshift at the limiter, regardless of mode.
My little bit of advice on CS45 vs R....I have owned a CS40 and Mk7.5 R and currently own a Mk8 R Performance Pack, honestly, they are very different cars, my personal opinion is I would choose the Clubsport models over R models, this is based upon my own preference for a more interactive, engaging driving experience. In the real world, the Clubsport will feel just as quick, if not quicker due to the weight advantage. Traction won't be an issue as you learn to moderate the throttle...Given the choice, Clubsport everytime for me. (I have just ordered a CS45 myself as well)
You can get that fixed with a DSG tune though. TVS are your goto people for that.
