If the s was making and "sssss" sound then "a" would be correct but since the s is part of an abbreviation (STI-Subaru Tecnica International) then the beginning of the s makes an "e" sound (and e is a vowel) therefore "an" would be correct.
all AWD cars will have 3 differentials, otherwise it wouldn't be road worthy.... Subaru's tend to have limited slip which is maybe what you mean. Allowing all wheel power during tire slippage.
@@krebgurfson5732 can't compare an awd elecrtronic toy which can barely get you out of a puddle. If awd was that great then why rally cars would bother with a true and tested mechancial torsen?
@@wrx5555 Měl jsi to v Auto mínus že? Proč ne v manuálním módu max na zadek? Mám přesně tohle STI nově, taky bych se to rád naučil, ale zatím někde bezpečně až u nás bude zase sníh 😀
