Released in 1991, the Cappuccino managed to slip into the Kei car category despite its turbocharged engine. The 657cc DOHC turbocharged I3 engine barely met Kei automotive regulations, which required an engine of less than 660cc and it was also just small enough. The engine produced 63 hp which was enough for the small size and it has been a fan favorite since its release.

The first generation of the Daihatsu Copen was released in 2002 and it was an impressive Kei car that many still love today. In Japan, the car was equipped with a 659cc I4 turbocharged JB-DET engine developing 63 hp. However, the engine did not meet the environmental regulations of many other countries, so it was also available with a 1.3-liter non-turbo engine in 2007 for European countries. This engine was indeed more powerful, but as a Kei car the original specs were also fantastic.


Its look is often considered very toy and cartoonish, however, the car is definitely nice and the different looks make it stand out. Since then there has also been a second generation, showing how successful the original Daihatsu Copen was. Having said that, the original has become quite collectable, with many loving it and many being disappointed when it was taken off the market.
