Audi RS5 (2017-2025) Pros and Cons

Pros	Cons
Superb all-weather performance	Not the driver's car it could be
Practical Sportback model	Turbocharged engine is short on character
First-rate interior quality	Thumpy ride over poor surfaces

Quick Summary

The Audi RS5 (2017-2025) is a fast, secure, and handsome all-rounder that combines 444bhp of turbocharged performance with the stability of all-wheel drive quattro. Available as both a two-door coupe and five-door Sportback hatchback, it offers practicality alongside genuine straight-line speed. The cabin is exceptionally well-appointed with high-grade materials, intuitive MMI infotainment, and a configurable Virtual Cockpit display. With a 410-litre boot (465 litres in the Sportback), it provides useful everyday versatility for a performance car.

Whilst the RS5 never quite reaches the dynamic heights of the BMW M4, it compensates with all-weather security and civilised daily usability. The 2.9-litre twin-turbo V6 is responsive and forceful, though lacking the character of naturally-aspirated rivals. The eight-speed automatic gearbox is smooth and nearly as snappy as dual-clutch alternatives. Running costs are substantial, with fuel consumption typically in the low 20s under spirited driving, insurance groups 42-47, and premium tyre costs around £500 per set. However, fixed-price servicing and parts availability help manage long-term expenses.

Best for: Buyers seeking a fast, secure, and practical performance car with all-wheel drive capability, those who value interior quality and technology, and drivers prioritising all-weather stability over outright handling dynamics.

Not ideal for: Keen drivers seeking the sharpest handling and most rewarding driving experience, those wanting engine character and musicality, or budget-conscious buyers concerned with fuel economy and running costs.


Comparison vs Key Rivals



The Verdict

You should buy the RS5 if: You seek a fast, secure, and practical performance car with all-wheel drive capability, value interior quality and technology, and prioritise all-weather stability over outright handling dynamics.

Consider alternatives if: You're a keen driver seeking the sharpest handling and most rewarding driving experience, desire engine character and musicality, or are concerned with fuel economy and running costs.

Competitive Position: The Audi RS5 (2017-2025) is a capable performance car that excels in all-weather security and practicality, particularly with the five-door Sportback variant. Whilst it lacks the dynamic sharpness of the BMW M4 and the engine character of the Mercedes-AMG C63 Coupe, it offers a compelling alternative for those prioritising stability, interior quality, and everyday usability. The RS5's quattro all-wheel drive system and civilised demeanour make it an excellent choice for drivers who want genuine performance without sacrificing comfort or practicality. However, keen enthusiasts will find more rewarding alternatives in the BMW M4 or Mercedes-AMG C63 Coupe.
