Audi A4 (2016-2024) Pros and Cons

Pros	Cons
Quiet and comfortable on long journeys	Not as engaging to drive as the BMW 3 Series or Jaguar XE
Wide range of efficient petrol and diesel engines	The Avant is not as practical as larger estate cars for similar money
Well equipped, even in the base model	Ride comfort suffers with sport suspension

Quick Summary

The Audi A4 (2016-2024) is a classy and competent compact executive saloon and estate car that represents the fifth and final generation of this popular model line. It combines smart styling with a beautifully appointed interior, spacious seating, and a comprehensive range of impressively efficient engines. Whilst it may not offer the driving engagement of the BMW 3 Series or the aspirational appeal of the Mercedes-Benz C-Class, the A4 excels in delivering a refined, quality experience with excellent infotainment systems and the optional Virtual Cockpit digital display. Boot space is generous for its class, and the rear seats split and fold into three sections for added flexibility.

The A4 is particularly impressive on motorways and for long-distance driving, offering smooth engines and excellent insulation from road and wind noise. The SE trim represents the best value, offering generous equipment including climate control, cruise control, and alloy wheels at a competitive price. For maximum fuel economy, the 2.0 TDI Ultra diesel achieves around 50-55mpg in real-world driving, whilst petrol versions deliver approximately 40-45mpg. Running costs are reasonable, with insurance groups ranging from 19 to 39 for mainstream versions. The A4 Avant estate provides additional practicality for those needing extra space, though it doesn't match larger estate cars in versatility.

Best for: Drivers seeking a refined, well-equipped executive saloon or estate with excellent comfort and efficiency, those prioritising long-distance comfort, and buyers wanting a quality interior and advanced technology.

Not ideal for: Those prioritising engaging driving dynamics, buyers seeking maximum practicality in an estate format, or those wanting the sportiest handling in the executive class.


Comparison vs Key Rivals



The Verdict

You should buy the A4 if: You prioritise refined comfort and long-distance driving, value a well-equipped interior with advanced technology, or seek a practical executive saloon or estate with efficient engines.

Consider alternatives if: You want the most engaging driving dynamics, require maximum estate car practicality, or desire premium badge prestige above all else.

Competitive Position: The Audi A4 (2016-2024) is a strong contender in the compact executive segment, offering excellent refinement, quality, and technology at a competitive price point. Whilst the BMW 3 Series edges ahead with superior driving dynamics and the Mercedes-Benz C-Class offers greater prestige, the A4 delivers outstanding value through its comprehensive equipment levels, efficient engines, and impeccable build quality. For buyers prioritising comfort, technology, and long-distance capability over outright sportiness, the A4 represents an intelligent choice that combines practicality with executive appeal.
