7. Suzuki Alto Turbo RS
Suzuki sold the Alto outside Japan as a compact car. But in Japan, it is still a Kei Car with one interesting version, the Alto Turbo RS. It is a hot hatch with five doors, three cylinders, aggressive looks, and an all-wheel-drive option.
Unfortunately, it comes with a lackluster 63 HP, 660 CCM turbo engine, which not many owners appreciate. The legal limit for modern Kei Cars is 63 HP, but most manufacturers offer tunable engines. They are easy to modify to close or over 100 HP, so owners can enjoy some real performance. And this is the case with the Turbo RS.
