Is there ANY chance that these will become a thing again?

VW uses an I5.

we're not talking about trash an/o/n

too bad 5 cyls are usually smoother than 4 bangers

>unbalanced
>being so dumb you don't understand the i5's and v10's are the most geometrically balanced around
>Does not understand Counter weights on crank shafts or block weights.
get out

>most balanced
>needs balance shafts

not him but are you daft?
the i5 and v10's dont require those weights , thats the whole reason regular engines arent as efficient and balanced. get out of your highschool auto class and learn before shit posting.
also
>balance shaft
for real? Shafts/ have you ever even seen a crank case or shaft/ do you know what the weights look like? get out of here middle schooler and take your FRS with you

>the i5
>dont require those weights
but they do

kek, the ones that don't require them are the I6s and V12s

Didn't Volvo prove they were viable in touring and in a heavy wagon no less? Why is this a question still? Every engine works if designed and implemented well.
