Simplest answer would be “Company Lore” but I know that won’t satisfy the curiosity.
Sinistra Motors is an American car company that started in 1947 and has been making cars with the engine the right way around since the start (Longitudinal arrangement). After the founder crashed one of their first cars on a snowy winter morning, he set about making a ‘safer’ car.
Long story short, the founder, Luke Sinistra, is the CEO of a much more modern car company who went back in time. And yes, there’s a reason he’s still alive after all that time, but I won’t get into the details, they’re not too important here. Suffice it to say that he came from a time and car company where AWD was a thing, and never really learned RWD well enough to handle higher power and skinny tires.
So the reason for L-FWD is because it unlocks before T-FWD by quite a wide margin, and because the UE4 engine actually lets me fit some rather nice-sized power plants in these cars in that arrangement now. And because that’s the case, I adopted it as company lore because a lot of the Automation Car Companies have a quirk or two. Mine is SOHC with L-FWD. My previous company was DOHC with AWD, whenever possible.
As for why I’ve not made a company thread for Sinistra, I’m waiting for UE4 to stabilize out a bit more, mostly because I don’t like trying to build around potentially rapid balance changes.
