AMR/Pro versus Mercedes AMG GT Pro

[leerandle]

Whilst flicking through various videos on Youtube last night, I noticed that Schmee150 had reviewed the new Mercedes AMG GT R Pro and thought that it seems similar to the Aston Martin Racing/Pro 'range'. Not only in the basic colour of grey/lime accents, but obviously the up-rated spec performance/aero/interior etc.

I wonder if there any link/agreement regarding the 'range' between the two brands (Knowing about the Engine/infotainment tie in) or just a coincidence ?

I do like the look of the AMG GT R, but would never buy one (Or even afford one).

When I noticed the AMG GT R Pro presentation I linked it to the Porsche 911 GT3 RS. A car very much suited to track-day use because of aerodynamic modifications - front splitter, flics, louvres, huge wing with Gurney-flap, and coil-over multi-adjustable suspension (enhancements). Roll cage and four-point-harness-systems are further features that indicate track usage. I don´t recognize any of these features in Aston Martin AMR cars - which is more a colorful marketing labeling?
Because of the different target niche markets I would not expect any agreement with AML in place. What I believe is: AMG and Porsche are closely watching each competitive move of the close rival and neighbour.
In 2019 the new Vantage GT4 race car will compete against the AMG GT4 and Cayman GT4 for use on track only - and that might be more interesting than such a compromise like the AMG GT R Pro - which cannot offer the performance and safety of a GT4 car and at the same time does not represent the elegance of an expensive sports car.
