Would wish that soon there would be more prototypes. The other chassis manufacturers of the LMP2 and LMP3, and the current LMP1 class.
You could try the URD PX (paid mod), had the AudiLMP1, the Porsche LMP1, the Nissan LMP1 and Oreca LMP2 (Oreca5). Oh and the Rebellion LMP 1 (2015)
I would just add that URD has just recently updated ONLY the Audi LMP1 car to dx11 and rain effects. The rest of the cars will follow, at some point.
The current LMP1 class is rapidly dying, so we decided against licensing those cars. We are monitoring whatever class will replace it in popular endurance series and we are also looking at our options to license more prototypes in general.
Sad news indeed, but understandable. I remember from Mike Conways explanations in 2015 that the hybrid deployment is fully-automatic. There is nothing to press to deploy it (with the exception for the quick overtake button). The location of the deployment can be managed tho but it's mapped. Hence, what is really missing is the 4WD during the accelerations and eventually a boost pass. Also, there were 8 LMP1 out of 10 without Hybrid system last year (2018), with some capable to get below 3'20 at Le Mans. Hence, a SMP or Rebellion LMP1 could do the job as well
