It is still used for this purpose in the context of the classic-car hobby, auto racing, and so forth.

The automotive industry currently uses the International System of Units / le Système international d'unités (SI), a modern metric system for this purpose worldwide (e.g. 6.1 litre Hemi). However, in markets accustomed to cubic inches, the actual displacement measurements of an engine are still given by many manufacturers in these units, usually along with metric value; e.g. the 6.1-litre Hemi's published displacement is 370.0 CID/6,059 cc.[1][2][3][4]

My car is a 376, not a 6.2 liter or litre for that matter. It's an American car in an American country, it should be referred to as a 376ci.
