A great and exciting report to start off with, and looking forward to the next!
One thing that I do question is regarding Mercedes-Benz/Mercedes-AMG.
OK, we know that AMG is handling development of the upcoming, next-generation SL-Class, and going alongside the GT with it, as the GT is a series-production model. We also know that originally, M-B was going to develop the SL-Class and SLK-Class together originally, but, that was revised to go with AMG and the GT, instead, which will result in the SLK going into the history-books when it's life-cycle is over. There was also word that there was to be a co-development effort with Nissan, with the next-generation Z-car and the SLK (similar to Toyota with BMW with the Supra and Z4), however, that's off the table.
Now, as the next SL is being developed by AMG now, the reports have it that it will be more of a proper 2+2, and to separate it further from the 2-seat GT; the current SL has a vestigial rear-seat setup similar to a Porsche 911. I can believe that for a 2+2 setup for the SL would allow it to be more relevant and more of a luxury-GT, separating it from the more focused GT. The SL would likely be longer overall than the GT, have a shorter hood and longer cabin, as I see it. Also, it's reported that the next SL will go back to a fabric-top, and some reports have a fixed-roof hardtop variant in the works, as well as the soft top, not unlike the GT.
As far as stepping on the toes of the S-Class Coupe and Cabriolet, I see mixed reports on this one. Some say that the S-Class Coupe and Cabriolet will disappear with the next-generation S-Class, as the larger SL-Class 2+2 will take the spot. Some went on to say that a large, full-sized 4-door CLS-like coupe will then take the place of the S-Class Coupe/Cabriolet. Others go on to say that the next S-Class will be a larger 2+2, but not large enough to overlap with the S-Class Coupe, and something of a bridge between the GT and S-Class Coupe.
Also, regarding the V12 powerplant - recent reports at the time that I post this say that the AMG65 models, with the V12, are being ended. No AMG models will use a V12 any longer. However, this is not to be mourned, for the hybrid AMG73 models are on the way, this being a twin-turbo 4.0L V8 mated to an electric motor, and produce in excess of 800HP, considerably more powerful than the V12. AMG did develop the V8 and V12 power-plants, but the V12 is to be used for Mercedes-Maybach models, as this range is expected to expand.
