Mind that power&drive-train control / setting will spread from F01 into other models as well: 5er, 6er, PAS etc.
So, benchmarking Sport & Sport+ modes to various M5 settings is logical.
Also: M5 can either produce 400, or 500hp.
So, benchmarking a N64 V8 TT to S85 V10 NA is also logical.
So, to make the new M5 better from the current one, the standard new 5er chassis & body should already be better than the current M5. Since the standard chassis & body are the platforms for the M-version. Therefore all the benchmarking.

F10 will be benchmarked to different models as well - especially for final fine set-ups: XF, FL A6, new E-class, F01, FL Quattroporte. BMW men also record Panamera & W212 drives & times on the Ring - so they can compare it to the ones of F10.
