Vehicles from 2018 make up about 22.4%, while a smaller portion, around 7.1%, were manufactured in 2020. This suggests a significant concentration of these models from 2019, with fewer newer 2020 units, possibly reflecting production or sales trends during that period.

Based on the available data for the Hyundai i20 (2018-20) 5DR Hatchback 1.0 T-GDI 100 SS EU6 SE, all vehicles are equipped with an engine capacity of 998cc and run exclusively on petrol. This suggests a uniform specification across the sample, indicating that the model consistently features a 1.0-liter petrol engine, likely contributing to its efficiency and compliance with EU6 emissions standards.
