The turbocharged M-cars certainly represent a transition (for better or worse) for BMW, and in particular BMW M.
Although the N/A engines with their ITBs and melodic symphonies are a thing of the past, we can still honor and appreciate such masterpieces of engineering without drawing negativity to the future.
Looking back, the S65 is truly special in that not only was it "inspired" by motorsport, but it is also a base [engine] from which motorsports continue to borrow from to this day.
To me, that is an extraordinary legacy that we can all be proud of, and I will share my knowledge and findings below.
I hope this is something that not only E9X M3 owners can appreciate, but something the whole BMW enthusiast community can find excitement in as well.
The S65 engine (& its derivatives) continue to live on in various racing applications (including in the 24 Hours of Le Mans, the 24 Hours of Nürburgring, etc.) by different teams in various cars/chassis, and in various configurations (displacements ranging from 3.6L~4.5L+).
I've compiled (an incomplete) encyclopedia on racing engines that use the S65 as a base engine.
Some of these you've probably never heard of while others (like the Z4 GT3) are quite familiar.
I also encourage fellow members to contribute more information regarding S65-based engines in racing applications. Enjoy

As a result of this research and in order to comply with the ACO’s homologation requirements the new engine will be based on a BMW 4,0 litre V8 engine. This engine has many distinct advantages over other available engines such as its low weight and high specific power output in road going form.

The engine was introduced for the 2011 season, following the ACO’s decision to mandate production based engines for the LMP2 category. We chose the BMW S65 4,0 litre V8 as our base engine (fitted to the M3 at the time) as it was available, reasonably priced and had a high specific output in roadcar form. We sourced the cylinder block and heads from our local BMW dealer and set about converting the engine for racing use. Cars fitted with the HK engine won races & championships in the LMP2 category in Europe and Asia.
