The second-generation Kia Soul (2014-2019) brought significant upgrades, including a stiffer chassis, refined styling, better interior materials, and available modern tech like Apple CarPlay/Android Auto by 2018, while maintaining its iconic boxy design and practicality. Key features included available turbo engines (from 2017), an all-electric Soul EV, improved safety tech, and more cargo space, making it a more refined yet still affordable compact.
