ive thought about it for a while, and ive realized that beamng has no V12's, I guess I could count the Scintilla, wait no, thats a V10, but ive always wondered why is there no V12s? I mean sure V12s have more of a luxury purpose, usually used for expensive, over-weight high tier luxury sedans/vans/suv, while V8's are used for pure power, having more acceleration, and torque, but why no V12s? beamng has a few vehicles that can be considered luxury, like the Bastion, its more of a sports car or performance but it probably does have a luxury version. maybe also apply the V10 on every car IF its able to fit. this is just a general question, I could appreciate it if I put a 5.7L V12 (only if it fits) on a Gavril D-series then just run it through Johnson valley or Jungle rock island. to sum it up, I just want stronger engine power, and more variety to engine customizations, but I still appreciate all the special little things that makes the customization so good in this game.
I don't think V12 in the Gavril D-Series is going to happen in near future, or ever. But you can download RK's engine mod from repo. It has great variety of options for engine customization.
