Engine choices, too many and too confusing

[Draigflag]

I know this has been discussed before, I can't remember what the outcome was. But when users set up a vehicle profile, and they are asked to select an engine variant, the H4, L4, gas/diesel options are confusing and often, there are more choices than actually exist. This also becomes apparent when researching vehicles and applying filters, some cars which might only have 2 engine choice options, have 6 or 7 options to choose from, and it's obvious from the split that pepeople don't fully understand and just click one "that will do"

Would it not be better to offer the capacity of the engine in Cc or litres? I think most countries the World over use litres as a form of measuring engine capacity, 2.0 litre, 3.0 litre and so on. And then perhaps have a fuel option, gas diesel, hybrid, electric. Just an idea to make researching vehicles easier, and of course, with less options, all the data combined will be far more accurate than spread across variants of engines and fuels in cars that don't even exist.
