noun
RV; recreational vehicle; SUV; four-wheel drive car/minivan
In Japanese, アールブイしゃ typically refers to a category of vehicles that includes SUVs, crossovers, and four-wheel-drive passenger cars, but not large camper vans or motor homes. The English gloss 'recreational vehicle' can be misleading because in American English it often implies a camper.
最近、アールブイ車の人気が高まっている。
Recently, the popularity of RVs (SUVs) has been increasing.
彼は新しいアールブイ車を買って、家族でキャンプに行った。
He bought a new SUV and went camping with his family.
This is the literal translation of 'sports utility vehicle' and is sometimes used in formal contexts, but アールブイ車 is the common term.
From English 'RV' (recreational vehicle) + 車 (car). The Japanese usage has narrowed to exclude large campers.
