Need help making a div with a background image responsive

They basically did the same thing from what i am seeing.

I’m not totally sure, but i think Its just that the part of the image being cutout is not the car itself. This is because the car only takes up half of the screen so it mostly does not get cut off (instead he black surrounding it).

Your web page with the GTR still looks good however.
