Suzuki Alto Turbo RS - Oh. My. Goodness. We all knew that Suzuki does small cars well, but this hot Kei hatchback takes it to the next level. With the cute face of a small, angry Pokémon, a 63bhp, 0.7-litre three-cylinder engine and a kerb weight of just 670kg, the Alto Turbo RS is sure to have all the charm you could ask for, and none of the expense of a full-sized hot hatch; it achieves 71mpg, according to Suzuki. I wanted one instantly after seeing one on the streets of Japan.
