Iame x30 engine series'

I’m looking at X30 lumps and wondered how the engine age series works such as ‘V’ series,‘N’ series, ‘S’ series
Any help appreciated

The letter before the serial number is just a production series code, and gives you an idea of the age of the case. N engines are about 6 yrs old, S about 4, and the V series came out in 2019.
