Nothing like some friendly competition.
A few days ago, Porsche announced the 911 GT2 RS equipped with a Manthey Performance Kit set a new Nurburgring lap record time of 6:43.00, thus beating the previous record time of 6:48.047 set by the Mercedes-AMG GT Black Series by an impressive 4.747 seconds. It's quite an achievement and based on recent history, it's only a matter of time until the record is smashed once again.
For now, Porsche is basking in reflected glory and Mercedes-AMG has something to say about that. In an official Facebook post, Mercedes-AMG congratulated its rival for setting the new record, but couldn't help itself in pointing out one critical detail.
"Fair competition has always inspired us. Congrats on that belter of a lap on the Nordschliefe, Porsche - even though it took an additional performance kit to beat the record time set by our series production Mercedes-AMG GT Black Series."
It's a fair point to make and it should also be emphasized both extraordinary cars were produced at the end of the respective model's lifecycle. The 991.2-based 911 GT2 RS debuted for 2018 and the 992 generation 911s are already on sale. A new GT2 RS is only a matter of time. As for the AMG GT, it launched for the 2015 model year and it's a known fact the German automaker is currently hard at work on its successor.
A Black Series model typically signifies the ultimate version of a particular AMG model, so it's doubtful another more powerful AMG GT will arrive before it's discontinued. Still, we wouldn't rule out a performance pack of some sort to boost performance even further. If Porsche can do it why not AMG, despite the latter's Facebook statement.
For decades, there was supposedly a "gentleman's agreement" among the CEOs of Porsche, Mercedes, and Audi to never build a direct 911 rival. The AMG GT ended that. It never achieved the same wide-scale name recognition as the 911 but the Porsche has been around for decades.
