What are the key safety features of the Audi S5?

All versions of the Audi S5 come with a solid suite of safety features, including multiple airbags, as well as stability and traction control. The quattro four-wheel drive means you get a sporty feel with the reassurance of all-wheel grip. Later models add advanced driver assists, such as adaptive cruise control, lane-keep assist and automatic emergency braking.

What engine options are available with the Audi S5?

The early 4.2-litre V8 petrol is known for power but relatively poor fuel efficiency. From 2012 to 2017, the S5 switched to a 3.0-litre supercharged V6 that offered plenty of acceleration. From 2017, you’ll find a turbocharged 3.0-litre V6 with brisk performance and better fuel economy. As petrol, diesel and mild hybrids are available, with six-speed automatic or manual gearboxes, you can choose which suits you best.

What are the standard technology and infotainment features in the Audi S5?

The S5 comes well-equipped, with early cars offering Bluetooth, DAB radio and navigation. Post-2016 models gain Audi’s MMI infotainment touchscreen, smartphone mirroring and (on higher trims) Virtual Cockpit digital instruments. Sound systems and leather upholstery, with options for full connectivity and premium Bang & Olufsen 3D audio, give the cabin a premium feel.

What is the fuel consumption of the Audi S5?

The V8 S5 averages around 23mpg, while the V6 from 2012 claims an economy improvement to about 30mpg. The latest turbo V6 S5 (from 2017 onwards) offers around 35mpg in real-world conditions, depending on driving style, chosen body and specification.

What should I check when buying a used Audi S5?

Check for a full main dealer or specialist service history – regular maintenance is crucial on performance engines and quattro systems. Listen for rattles and look for warning lights from the infotainment system, and test all in-car electronics thoroughly. The AA Vehicle Inspection service gives you extra peace of mind when you're buying a used car.

Are Audi S5 cars reliable?

Audi S5s are generally solid, with most owners reporting few major issues if maintenance is up to date. Some older V8s had timing-chain concerns, while infotainment glitches can affect later models. Costs for repairs and parts are higher than mainstream cars and reliability scores hover between average and below-average compared to rivals.
