Quick Summary

The Audi A3 Mk4 (2020-present) is a premium five-door hatchback that maintains Audi's competitive position in the prestige compact car segment. With a 380-litre boot expanding to 1,200 litres with rear seats folded, it offers excellent practicality for a small family. The car features comprehensive standard equipment including a 10.1-inch touchscreen, 10.25-inch Virtual Cockpit digital display, satnav, Apple CarPlay/Android Auto, and advanced safety systems.
