In addition to Andy G's excellently described listing of the various series of the roadster, I would like to add just one detail. With the introduction of the Roadster Sport in 2010 and afterwards the bespoke models as well the performance of the 3.0 Series 2 engine increased from about 206? PS to ca. 230 PS. This was clearly noticeable, I had both models. But the Series 1 Roadster I also had was a much more sporty machine and the transmission was better graded and felt better.
