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. 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 comfort and refinement, making it an excellent choice for those prioritising a serene driving experience and long-distance capability.

The A4 offers practical boot space comparable to the contemporary 3 Series and superior to the C-Class, with flexible rear seats that split into three sections. An estate variant, the A4 Avant, provides additional versatility for those needing extra luggage capacity. Running costs are competitive, with diesel models achieving 50-55mpg and petrol versions delivering 40-45mpg in real-world conditions. The well-equipped SE trim offers excellent value, though buyers should avoid larger alloy wheels and sport suspension for optimal ride comfort. In 2024, the A4 was succeeded by the A5, which now serves as Audi's combustion-engined executive saloon.

Best for: Drivers seeking a refined, comfortable executive saloon or estate with excellent build quality, efficient engines, and premium technology at a competitive price point.

Not ideal for: Buyers prioritising engaging driving dynamics, maximum practicality in an estate format, or those who prefer sportier suspension setups as standard.
