What qualifies as a kei car?
A kei car, also known as a keijidōsha or light automobile, is a special category of small vehicles that are popular in Japan. These compact cars are defined by their limited engine size and overall dimensions, making them a unique and practical choice for urban driving and parking in the country.
Definition of a Kei Car
To qualify as a kei car in Japan, a vehicle must meet the following criteria:
- Engine displacement of 660 cc or less
- Overall length of 3.4 meters (11.2 feet) or less
- Overall width of 1.48 meters (4.9 feet) or less
- Overall height of 2 meters (6.6 feet) or less
- Unladen vehicle weight of 660 kg (1,455 lbs) or less
These strict size and weight limitations help kei cars maintain their compact and maneuverable nature, which is essential for navigating Japan's crowded urban environments and tight parking spaces.
History and Popularity of Kei Cars
The kei car category was first introduced in Japan in 1949 as a way to provide affordable and practical transportation options for the post-war population. Over the decades, kei cars have become increasingly popular, accounting for about one-third of all new vehicle sales in Japan as of 2022.
The appeal of kei cars lies in their combination of small size, low cost, and high fuel efficiency. They are particularly popular with elderly drivers, young families, and urban residents who value the ease of parking and maneuvering in tight spaces. Kei cars also enjoy certain tax and insurance benefits in Japan, further contributing to their widespread adoption.
Kei Car Models and Manufacturers
Major Japanese automakers like Suzuki, Daihatsu, Honda, and Nissan are the primary producers of kei cars. Some popular kei car models include the Suzuki Alto, Daihatsu Mira, Honda N-Box, and Nissan Dayz.
While kei cars are primarily designed for the Japanese market, a few models have been exported to other countries, such as the Suzuki Alto and Daihatsu Mira. However, their limited size and engine displacement make them less practical for use outside of Japan's unique urban landscape.
