Kei Cars: The Little Cars That Can

In the Western world, cars seem to have been getting bigger.  For example, my early 2000 Volvo S70, a generous sedan when it came out, is shorter than the more modern “little” hatchbacks in the supermarket car park beside it.  However, this isn’t the case around the world.  In Japan, congestion is a problem in busy cities such as Tokyo and Kyoto, so one of the solutions was to introduce what are known as kei cars, also known as compact cars. Some people call these K-cars, as this is approximately the way the word “kei” is pronounced.

The concept of kei cars isn’t new; in fact, the Japanese government introduced the general idea and legislation related to these vehicles in the late 1940s as part of the post-WWII recovery efforts.  Back then, it was more about encouraging car ownership and stimulating the local automotive industry (and you can see for yourself how well that worked, given the number of Japanese makes on Australia’s roads).  Today, however, it’s more about congestion and fuel consumption.

What is a kei car?  As the Japanese name suggests (in full, it’s kei-jidōsha), it’s a small car.  Specifically, it’s one that has restrictions on its size, both in terms of its dimensions and its engine displacement.  To qualify as a kei car, an automobile has to be no taller than 2 metres, no wider than 1.45 metres and no longer than 3.4 metres.  In terms of engine displacement, the maximum allowed is 660 cc. There’s no official limit on engine power, but it’s very unusual for a factory kei car to have more than 47 kW.  Not that tuning and tweaking to get a bit more power is out of the question for those interested… Most of them are speed-limited to 140 km/h, which makes sense, given that these are designed for crowded city streets, not open road rural running.  The width means that they don’t handle quite as well at high speeds, so that’s another reason why their top speed isn’t as high as what you’d find with the average Toyota Corolla.

Needless to say, electric kei cars are out there as well.

To encourage the adoption of kei cars, the Japanese government has a few incentives set up.  If a car qualifies to have the distinctive yellow kei plates, it’s exempt from the need to buy parking space (apparently, to buy a car in Japan, you first have to buy street space to park it).  Various on-road taxes are reduced with kei cars, as these taxes are based on things such as the engine displacement and the weight. 

Now, we all know that where there are large numbers of people, there are houses to fix and goods to be transported, which require vans and trucks.  Your typical kei car has the sort of cargo space that would suit a minimalist (Marie Kondo would love these, if she doesn’t already).  However, kei vans and kei trucks are a thing – although we’d call latter kei utes, as they’re “pickup truck” rather than a miniature version of a big old Scania.  The kei vans or microvans are allowed to be taller than the kei cars, which allows the to carry more of a load and has earned them the nickname of “miàn bāo chē” (meaning “bread loaf cars” in nearby China. The kei trucks have the same basic wheelbase but a cab-chassis layout.

Because of their low fuel consumption, suitability for urban settings, kei cars and their relatives are growing in popularity in other parts of the world outside Japan.  Their general cuteness relates to another Japanese concept, namely the kawaii (cute) aesthetic.  Although many customers in Australia are leery about very small cars, given that physics says that they’re not going to come off well in a collision with an SUV, some popular kei marks are found in the Aussie market. Do any of these sound familiar?

These are all “regular” cars that meet the criteria for kei cars that you can find down at your local dealer (which is why we have them in our reviews page).  Plenty of people also arrange for private imports of popular kei cars such as various Daihatsu models, the stylish Honda Beat coupe convertible, the Suzuki Every van, the Toyota Copen sports car and the Subaru Sambar, just to name a few. There’s even a kei version of the Mitsubishi Pajero, the Pajero Mini.
