The data indicates that the majority of the Audi A1 (2010-15) 3DR Hatchback 2.0 TDI DPF SS 143 EU5 Sport models were manufactured in 2012, accounting for 51.6% of the sample. Vehicles from 2014 constitute the second largest group at 25.8%, followed by 2013 at 19.4%. Only a small proportion, 3.2%, were produced in 2015. This suggests a significant production peak around 2012, with a considerable number of vehicles still on the road from that year, and a sharp decline in manufacturing in the subsequent years.

Based on the available data for the AUDI A1 (2010-15) 3-door hatchback 2.0 TDI DPF SS 143 EU5 Sport 6SPD models, all vehicles are powered by diesel fuel, with a consistent engine capacity of 1968 cc. This indicates that the entire sample exclusively uses diesel engines of similar size, highlighting a uniformity in engine specifications within this particular model range.
