V8 was available until the Gen 2 came out late 2016/17. All facelift cars (2015 on I think) came with the s-tronic. They can be distinguished by having single round exhausts instead of the quads, 3 fins at the back instead of 4 and the switchgear has Chrome edging. Front lights look slightly different too. The only car in that link that I can see being the r-tronic is the grey one with 99k miles on it, that looks like a pre-facelift.
