Audi A3 Mk4 (2020-present) Pros and Cons

Pros	Cons
Lots of luxury and safety kit	Expensive for a car of this size
Very good to drive	Not as well finished as some rivals
Practical enough for a small family	There's a firm edge to the ride

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 practicality comparable to larger rivals. The car features a well-appointed interior with a 10.1-inch touchscreen, 10.25-inch Virtual Cockpit digital display, and comprehensive safety equipment including automatic emergency braking and lane departure warning. A 2024 facelift introduced styling refinements and additional technology enhancements.

The A3 delivers an engaging driving experience with responsive steering, strong grip, and tight body control, though the ride has a noticeably firm edge. Turbocharged petrol engines achieve around 50mpg, whilst diesel variants exceed 60mpg. Running costs align with BMW 1 Series and Mercedes A-Class equivalents, though the A3 commands a slight premium. Despite not advancing significantly from its predecessor, the A3 remains a desirable, well-equipped, and entertaining car to drive, justifying its position amongst the prestige hatchback elite.

Best for: Buyers seeking a premium, well-equipped hatchback with strong driving dynamics, luxury features, and practical space for small families. Not ideal for: Budget-conscious buyers, those prioritising softer ride comfort, or those seeking the most spacious compact hatchback available.
Comparison vs Key Rivals



The Verdict
