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 the fifth-generation and final iteration of this iconic executive saloon, representing arguably the most complete A4 ever produced. With its smart styling, beautifully appointed interior, spacious seating, and impressively efficient engine range, it offers a compelling package for discerning buyers. The A4 provides boot space comparable to the BMW 3 Series and superior to the Mercedes-Benz C-Class, whilst the optional A4 Avant estate variant delivers additional practicality for those requiring extra cargo capacity. In 2024, the A4 was succeeded by the A5, as Audi realigned its naming conventions to denote combustion-engined vehicles with odd numbers.

Handling is satisfying and assured, with excellent body control and strong grip in front-wheel-drive versions, whilst quattro all-wheel-drive variants offer true all-weather capability. The ride quality strikes a fair balance between comfort and control, sitting between the cosseting Mercedes C-Class and firmer BMW 3 Series. With smooth engines, excellent insulation, and first-class infotainment featuring the Virtual Cockpit digital display, the A4 excels on motorways and long-distance journeys. Fuel economy is impressive, with diesel models achieving 50-55mpg and petrol variants around 40-45mpg in real-world driving. The SE trim offers the best value, providing comprehensive equipment including climate control and cruise control at a lower price than sportier variants.

Best for: Executive car buyers seeking a refined, well-equipped saloon or estate with excellent long-distance comfort, efficient engines, and premium build quality without sacrificing practicality.

Not ideal for: Drivers prioritising engaging, dynamic handling comparable to the BMW 3 Series or Jaguar XE, or those requiring maximum boot space at a lower price point.


Comparison vs Key Rivals



The Verdict

You should buy the A4 if: You seek a refined, well-equipped executive saloon or estate with excellent long-distance comfort, efficient engines, and premium build quality without compromising practicality.

Consider alternatives if: You prioritise engaging, dynamic handling comparable to the BMW 3 Series or Jaguar XE, or require maximum boot space at a lower price point.

Competitive Position: The Audi A4 (2016-2024) is a highly accomplished executive saloon that competes strongly in its segment. Whilst the BMW 3 Series edges ahead for driving engagement and the Jaguar XE offers marginally better value, the A4 distinguishes itself through its superior interior quality, comprehensive equipment levels, and exceptional motorway refinement. It represents an excellent choice for buyers prioritising comfort, efficiency, and build quality over outright driving dynamics, making it a smart and competent alternative to its German and British rivals.
