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 practical space for small families. The car features a well-appointed interior with a 10.1-inch touchscreen, 10.25-inch Virtual Cockpit digital display, and comprehensive safety equipment as standard. A 2024 facelift brought styling refinements and additional technology enhancements, keeping the A3 fresh and desirable.

The A3 delivers an engaging driving experience with responsive steering, tight body control and strong grip, though the ride has a noticeably firm edge. Turbocharged petrol engines achieve around 50mpg, whilst diesel variants return upwards of 60mpg. Running costs align with rivals, though the A3 commands a premium purchase price. With luxury kit, advanced technology, and entertaining dynamics, it represents a compelling choice for those seeking style and substance, though build quality has slightly declined compared to its predecessor.

Best for: Buyers seeking a premium, well-equipped hatchback with engaging driving dynamics, those prioritising luxury and technology, and small families needing practical space with prestige appeal.

Not ideal for: Budget-conscious buyers, those seeking the finest build quality, or drivers preferring a softer, more compliant ride.

You should buy the A3 if: You seek a premium, well-equipped hatchback with engaging driving dynamics, prioritise luxury and technology, or need practical space with prestige appeal.

Competitive Position: The Audi A3 Mk4 remains a highly competitive premium hatchback, offering style, technology and practicality to match its BMW 1 Series and Mercedes-Benz A-Class rivals. Whilst the competition has significantly improved and the A3 hasn't progressed dramatically, it still delivers engaging driving dynamics and comprehensive luxury equipment. The A3 commands a premium purchase price and features a firmer ride, but compensates with excellent user satisfaction, strong grip and responsive handling. For those valuing prestige, technology and driving enjoyment over budget considerations, the A3 represents a compelling and desirable choice in the premium compact segment.
