About the Audi S5
Launched in 2007, the Audi S5 sits between the A5 and RS5 in Audi's performance line-up. The first generation (2007-2016) featured a 3.0-litre supercharged V6 producing 333bhp, while the second generation (2016-present) uses a 3.0-litre turbocharged V6 with 349bhp. Both generations offer coupe and Sportback body styles, with the latter providing increased practicality through four doors and a larger boot. Standard quattro all-wheel drive ensures excellent traction in all conditions, whilst build quality and interior refinement remain class-leading.
What Affects the Price of a Used Audi S5
Age and mileage are the primary factors influencing S5 values. Early 2008-2010 models now start around £8,000-£12,000 with higher mileages, whilst low-mileage facelift B8.5 models (2012-2016) command £18,000-£28,000. Second-generation cars from 2017 onwards typically range from £25,000 to £45,000 depending on specification and mileage. Body style affects pricing, with Sportback models often fetching £1,000-£2,000 more due to added practicality. Full Audi service history adds significant value, as do desirable options like Bang & Olufsen sound systems, adaptive dampers and Matrix LED headlights. Diesel S5 TDI models (2012-2018) offer lower running costs and hold value well. Condition is critical—neglected examples with worn interiors or incomplete service records sell for considerably less.
Tips for Buying a Used Audi S5
Always verify full service history, preferably from Audi main dealers, as cambelt and supercharger servicing on early models is expensive if overdue. Check for oil consumption issues on pre-2013 3.0 TFSI engines—excessive use may indicate bore wear. Inspect the quattro system thoroughly during test drives, listening for unusual noises from the differential and ensuring smooth power delivery to all wheels. Carbon build-up on intake valves is common on direct-injection engines, causing rough idling and reduced performance—budget for walnut blasting if symptoms present. Examine alloy wheels carefully for kerb damage and corrosion, as replacements are costly. Verify that all electronic systems function correctly, including adaptive cruise control, parking sensors and MMI infotainment. Consider approved used schemes from Audi for newer models, offering warranty coverage and peace of mind. Diesel S5 TDI versions provide excellent fuel economy but check DPF condition and ensure regular motorway use.
