In English, a small car is usually referred to as a "small car" or a "compact car". The term "small car" is used to refer to a car that is smaller than a medium-sized car, and a "compact car" is a car that is larger than a subcompact car but smaller than a mid-sized car.

The term "small car" originated in the early 20th century, when cars were first becoming popular and the different sizes of cars were being defined. "Compact car" originated in the 1950s, when car manufacturers began to produce smaller cars that were more fuel-efficient and affordable.

Here are some examples of sentences using these terms:

"I'm looking for a small car that's easy to park and good on gas."

"The compact car market has been growing in recent years as more people are looking for fuel-efficient vehicles."

"I own a small car, but I'm thinking of upgrading to a compact car with more features and comfort."

In Chinese, a small car can be referred to as a "小汽车" (xiǎo qìchē), and a compact car can be referred to as a "紧凑型汽车" (jǐncòu xíng qìchē).
