The i20 N is Hyundai's smallest and cheapest hot hatch, and one of the last affordable light cars built purely for fun. It pairs a turbo engine with a slick manual, a mechanical limited slip differential and a loud exhaust, in a tiny, agile body that's great fun on a back road. With keen pricing and a five year warranty, stretching to seven with Hyundai servicing, it outshines far pricier cars for driving enthusiasts who don't want to spend big.
