自動車가 빠릅니다

i remember "빠릅니다." by going brrrm brrrm cause it kinda sounds like that

the word for car here was first introduced as "automobile" but here , only "car" is accepted. makes me want to slap the duolingo owl

I am assuming that 빠르다 and 빨리 are of the same etymological root.

Would the infinitive (dictionary) form of 빠릅니다 be 빨다?
