。
She immediately headed toward the car.
Literal
She [topic-は] immediately car [possessive-の] direction [toward-へ] headed.
直ちに ('immediately') is a formal adverb — more crisp and urgent than すぐに. ~の方へ向かう ('to head in the direction of') uses 方 (direction) and 向かう ('to head toward'). The sentence reads like a factual report or narrative description.
